I am trying to add some custom logic to my semantic ui validation but can't figure out what I am doing wrong.
Basically, when the user selects "Yes" from the drop-down, I would like to make the "input_field" mandatory. If the user selects "No", the "input_field" becomes optional and the form can be submitted.
I tried searching for examples and followed some code from the Semantic Ui website but can't figure out what I am missing. Any advice would be appreciated as I am on a deadline for a project I am working on.
Form:
<div class="ui dimmer">
<div class="ui huge text loader">Loading</div>
</div>
<form method="post" action="" class="ui form" autocomplete="on">
<div class="ui segment">
<div class="ui two fields">
<div class='field'>
<div class="ui selection dropdown">
<input type="hidden" class="selectOption" name="select">
<i class="dropdown icon"></i>
<div class="default text">Select an option</div>
<div class="menu">
<div class="item" data-value="Yes">Yes</div>
<div class="item" data-value="No">No</div>
</div>
</div>
</div>
<div class="field">
<input id="input_field" name="input_field" type="text"/>
</div>
</div>
</div>
<button id="submit" class="ui green button" name="submit" type="submit">Submit</button>
</form>
Validation:
<script>
$('.ui.form').form({
keyboardShortcuts: false,
on: 'blur',
inline: 'true',
fields: {
selectOption: {
identifier: 'select',
rules: [
{
type: 'empty',
prompt: 'Please select an option'
}]
},
input_field: {
identifier: 'input_field',
depends: 'select',
rules: [
{
type: 'empty',
prompt: function() {
$('.select').on('change', function() {
if( this.value == 'Yes') {
return "Custom Validation";
}
return false;
}).trigger("change");
}
}]
}
},
onSuccess: function() {
$('.ui.dimmer').dimmer('show');
},
onFailure: function() {
event.preventDefault();
}
}
);
});
</script>
Figured out a solution for this! It might not be the best answer but it works and does what I am looking for.
<div class="ui dimmer">
<div class="ui huge text loader">Loading</div>
</div>
<form method="post" action="" class="ui form" autocomplete="on">
<div class="ui segment">
<div class="ui two fields">
<div class='field'>
<div class="ui selection dropdown">
<input type="hidden" class="selectOption" name="select">
<i class="dropdown icon"></i>
<div class="default text">Select an option</div>
<div class="menu">
<div class="item" data-value="Yes">Yes</div>
<div class="item" data-value="No">No</div>
</div>
</div>
</div>
<div class="field">
<input id="input_field" name="input_field" type="text"/>
</div>
</div>
</div>
<button id="submit" class="ui green button" name="submit" type="submit">Submit</button>
</form>
<script>
$('.ui.form').form({
keyboardShortcuts: false,
on: 'blur',
inline: 'true',
fields: {
selectOption: {
identifier: 'select',
rules: [
{
type: 'empty',
prompt: 'Please select an option'
}]
}
},
onSuccess: function() {
$('.ui.dimmer').dimmer('show');
},
onFailure: function() {
event.preventDefault();
}
}
);
$('.selectOption').on('change', function() {
if ( this.value == 'Yes' ) {
$('.ui.form').form('add rule', 'input_field', ['empty', 'integer']);
$('.ui.form').form('add prompt', 'input_field', 'Enter an integer');
}
if ( this.value == 'No' ) {
$('.ui.form').form('remove prompt', 'input_field');
$('.ui.form').form('remove rule', 'input_field');
}
}).trigger("change");
});
</script>
I was able to implement the validation rule by extending Semantic UI setting rules.
See below example:
$.fn.form.settings.rules.dependsOnFieldValue = function (value, dependFieldValue) {
var identifier = dependFieldValue.split('[')[0];
var dependValue = dependFieldValue.match(/\[(.*)\]/i)[1];
if( $('[data-validate="'+ identifier +'"]').length > 0 ) {
matchingValue = $('[data-validate="'+ identifier +'"]').val();
}
else if($('#' + identifier).length > 0) {
matchingValue = $('#' + identifier).val();
}
else if($('[name="' + identifier +'"]').length > 0) {
matchingValue = $('[name="' + identifier + '"]').val();
}
else if( $('[name="' + identifier +'[]"]').length > 0 ) {
matchingValue = $('[name="' + identifier +'[]"]');
}
return (matchingValue !== undefined)
? !( dependValue.toString() === matchingValue.toString() && value === '')
: false
;
};
Then in the form validation initializer you will pass the desired values as below:
$(".ui.form").form({
fields: {
select: {
identifier: 'select',
rules : [
{
type : 'empty'
}
]
},
input_field: {
identifier : 'input_field',
rules : [
{
type : 'dependsOnFieldValue[select[Yes]]',
}
]
},
...
}
});
Notice that we pass the <select> identifier (in this case also called select) within the first [] and then the value that we want to see to make the input_field mandatory ("Yes" in this case).
I installed "element-ui": "^2.3.7" and I use it in my Vue component :
<el-date-picker
v-model="valueDateTimeOrder"
type="daterange"
align="right"
unlink-panels
range-separator="To"
start-placeholder="Start date"
end-placeholder="End date"
:picker-options = "pickerOptions">
</el-date-picker>
in data:
pickerOptions: {
disabledDate(time) {
return time.getTime() > Date.now();
},
}
It's works perfect. But when I want to disable all in an array, I don't know how to do it. Because the array only exist after get api. But data is done after all this component, it cannot wait call the range. Help me to set picker-options. Thanks
I think this can help you.
var app = new Vue({
el: '#app',
data() {
var vm = this;
return {
disabledDates: [],
pickerOptions1: {
disabledDate(time) {
time = moment(time).format('YYYY-MM-DD');
return vm.disabledDates.indexOf(time)>-1;
}
},
value1: '',
val: ''
};
},
methods: {
appendDate () {
this.disabledDates.push(this.val);
this.$refs.picker.unmountPicker();
this.$refs.picker.mountPicker();
}
}
})

Does anyone know how to open a bootstrap modal with vue 2.0? Before vue.js I would simply open the modal by using jQuery: $('#myModal').modal('show');
However, is there a proper way I should do this in Vue?
Thank you.
My code is based on the Michael Tranchida's answer.

Example on Codepen if you are not familiar with Pug click View compiled HTML on a dropdown window in HTML section.
This is the basic example of how Modals works in Bootstrap. I'll appreciate if anyone will adopt it for general purposes.
Have a great code 🦀!
I did an amalgam of the Vue.js Modal example and the Bootstrap 3.* live demo.
Basically, I used the Vue.js modal example but replaced (sorta) the Vue.js "html" part with the bootstrap modal html markup, save one thing (I think). I had to strip the outer div from the bootstrap 3, then it just worked, voila!
So the relevant code is regarding bootstrap. Just strip the outer div from the bootstrap markup and it should work. So...
ugh, a site for developers and i can't easily paste in code? This has been a serious continuing problem for me. Am i the only one? Based on history, I'm prolly an idiot and there's an easy way to paste in code, please advise. Every time i try, it's a horrible hack of formatting, at best.
i'll provide a sample jsfiddle of how i did it if requested.
Using the $nextTick() function worked for me. It just waits until Vue has updated the DOM and then shows the modal:
HTML
<div v-if="is_modal_visible" id="modal" class="modal fade">...</div>
JS
{
data: {
isModalVisible: false,
},
methods: {
showModal() {
this.isModalVisible = true;
this.$nextTick(() => {
$('#modal').modal('show');
});
}
},
}
Here's the Vue way to open a Bootstrap modal..
Bootstrap 5 (2022)
Now that Bootstrap 5 no longer requires jQuery, it's easy to use the Bootstrap modal component modularly. You can simply use the data-bs attributes, or create a Vue wrapper component like this...
<bs-modal id="theModal">
<button class="btn btn-info" slot="trigger"> Bootstrap modal </button>
<div slot="target" class="modal" tabindex="-1">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Modal title</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
<p>Modal body text goes here.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</bs-modal>
const { Modal } = bootstrap
const modal = Vue.component('bsModal', {
template: `
<div>
<slot name="trigger"></slot>
<slot name="target"></slot>
</div>
`,
mounted() {
var trigger = this.$slots['trigger'][0].elm
var target = this.$slots['target'][0].elm
trigger.addEventListener('click',()=>{
var theModal = new Modal(target, {})
theModal.show()
})
},
})
Bootstrap 5 Modal in Vue Demo
Bootstrap 4
Bootstrap 4 JS components require jQuery, but it's not necessary (or desirable) to use jQuery in Vue components. Instead manipulate the DOM using Vue...
Launch modal
<div :class="modalClasses" class="fade" id="reject" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Modal</h4>
<button type="button" class="close" #click="toggle()">×</button>
</div>
<div class="modal-body"> ... </div>
</div>
</div>
</div>
var vm = new Vue({
el: '#app',
data () {
return {
modalClasses: ['modal','fade'],
}
},
methods: {
toggle() {
document.body.className += ' modal-open'
let modalClasses = this.modalClasses
if (modalClasses.indexOf('d-block') > -1) {
modalClasses.pop()
modalClasses.pop()
//hide backdrop
let backdrop = document.querySelector('.modal-backdrop')
document.body.removeChild(backdrop)
}
else {
modalClasses.push('d-block')
modalClasses.push('show')
//show backdrop
let backdrop = document.createElement('div')
backdrop.classList = "modal-backdrop fade show"
document.body.appendChild(backdrop)
}
}
}
})
Bootstrap 4 Vue Modal Demo
My priority was to keep using Bootstrap code, since they made the effort to make the modal work, fixin' the scrollbars and all. I found existing proposals try to mimic that, but they go only part of the way. I didn't even want to leave it to chance: I just wanted to use actual bootstrap code.
Additionally, I wanted to have a procedural interface, e.g. calling dialog.show(gimme plenty of parameters here), not just toggling a variable somewhere (even if that variable could be a complex object).
I also wanted to have Vue's reactivity and component rendering for the actual dialog contents.
The problem to solve was that Vue refuses to cooperate if it finds component's DOM to have been manipulated externally. So, basically, I moved the outer div declaring the modal itself, out of the component and registered the component such that I also gain procedural access to the dialogs.
Code like this is possible:
window.mydialog.yesNo('Question', 'Do you like this dialog?')
On to the solution.
main.html (basically just the outer div wrapping our component):
<div class="modal fade" id="df-modal-handler" tabindex="-1" role="dialog" aria-hidden="true">
<df-modal-handler/>
</div>
component-template.html (the rest of the modal):
<script type="text/x-template" id="df-modal-handler-template">
<div :class="'modal-dialog ' + sizeClass" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">{{ title }}</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body" v-html="body"/>
<div class="modal-footer">
<button type="button" v-for="button in buttons" :class="button.classes" v-bind="button.arias"
#click.stop="buttonClick(button, callback)">{{ button.text }}
</button>
</div>
</div>
</div>
</script>
component-def.js - contains logic for showing & manipulating the dialog, also supports dialog stacks in case you make a mistake and invoke two dialogs in sequence:
Vue.component('df-modal-handler', {
template: `#df-modal-handler-template`,
props: {},
data() {
return {
dialogs: [],
initialEventAssignDone: false,
};
},
computed: {
bootstrapDialog() { return document.querySelector('#df-modal-handler'); },
currentDialog() { return this.dialogs.length ? this.dialogs[this.dialogs.length - 1] : null; },
sizeClass() {
let dlg = this.currentDialog;
if (!dlg) return 'modal-sm';
if (dlg.large || ['large', 'lg', 'modal-lg'].includes(dlg.size)) return 'modal-lg';
else if (dlg.small || ['small', 'sm', 'modal-sm'].includes(dlg.size)) return 'modal-sm';
return '';
},
title() { return this.currentDialog ? this.currentDialog.title : 'No dialogs to show!'; },
body() { return this.currentDialog ? this.currentDialog.body : 'No dialogs have been invoked'; },
callback() { return this.currentDialog ? this.currentDialog.callback : null; },
buttons() {
const self = this;
let res = this.currentDialog && this.currentDialog.buttons ? this.currentDialog.buttons : [{close: 'default'}];
return res.map(value => {
if (value.close == 'default') value = {
text: 'Close',
classes: 'btn btn-secondary',
data_return: 'close'
};
else if (value.yes == 'default') value = {
text: 'Yes',
classes: 'btn btn-primary',
data_return: 'yes'
};
else if (value.no == 'default') value = {
text: 'No',
classes: 'btn btn-secondary',
data_return: 'no'
};
value.arias = value.arias || {};
let clss = (value.classes || '').split(' ');
if (clss.indexOf('btn') == -1) clss.push('btn');
value.classes = clss.join(' ');
return value;
});
},
},
created() {
// make our API available
window.mydialog = this;
},
methods: {
show: function show() {
const self = this;
if (!self.initialEventAssignDone) {
// created is too soon. if we try to do this there, the dialog won't even show.
self.initialEventAssignDone = true;
$(self.bootstrapDialog).on('hide.bs.modal', function (event) {
let callback = null;
if (self.dialogs.length) callback = self.dialogs.pop().callback;
if (self.dialogs.length) event.preventDefault();
if (callback && callback.df_called !== true) callback(null);
});
}
$(self.bootstrapDialog).modal('show');
},
hide: function hide() {
$(this.bootstrapDialog).modal('hide');
},
buttonClick(button, callback) {
if (callback) { callback(button.data_return); callback.df_called = true; }
else console.log(button);
this.hide();
},
yesNo(title, question, callback) {
this.dialogs.push({
title: title, body: question, buttons: [{yes: 'default'}, {no: 'default'}], callback: callback
});
this.show();
},
},
});
Do note that this solution creates one single dialog instance in the DOM and re-uses that for all your dialog needs. There are no transitions (yet), so the UX isn't too great when there are multiple active dialogs. It's bad practice anyway, but I wanted it covered because you never know...
Dialog body is actually a v-html, so just instantiate your component with some parameters to have it draw the body itself.
I create button with params for modal and simply trigger click()
document.getElementById('modalOpenBtn').click()
<a id="modalOpenBtn" data-toggle="modal" data-target="#Modal">open modal</a>
<div class="modal" id="Modal" tabindex="-1" role="dialog" aria-labelledby="orderSubmitModalLabel" aria-hidden="true">...</div>
From https://getbootstrap.com/docs/4.0/getting-started/javascript/#programmatic-api
$('#myModal').modal('show')
You can do this from a Vue method and it works just fine.

Vue.component('modal', {
template: '#modal-template'
})
// start app
new Vue({
el: '#app',
data: {
showModal: false
}

</div>
$(function() {
$('input.month-mode').datetimepicker({
viewMode: 'months',
format: 'MM/YYYY',
showClose: true,
maxDate: current_month,
});
});
I want to add close text to it. by default it shows 'X', but I want to change it. Is it possible?
You can use icons option to define a custom css class for your icon and then you can write a css rule to customize close text as shown below:
$(function () {
var current_month = moment(); // just a sample value
$('#datetimepicker1').datetimepicker({
showClose: true,
viewMode: 'months',
format: 'MM/YYYY',
maxDate: current_month,
icons: {
close: 'closeText'
}
});
});
.closeText:before {
content: "Close";
}

<link href="//cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.7.14/css/bootstrap-datetimepicker.css" rel="stylesheet"/>
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.js"></script>

<script src="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.6/js/bootstrap.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.7.14/js/bootstrap-datetimepicker.min.js"></script>
<div class='input-group date' id='datetimepicker1'>
<input type='text' class="form-control" />
<span class="input-group-addon">
<span class="glyphicon glyphicon-calendar"></span>
</span>
</div>
One way to do this is to use the icon classes to a add a new class and then use css to add some content. Something like:
$(function() {
$('input.month-mode').datetimepicker({
viewMode: 'months',
format: 'MM/YYYY',
showClose: true,
maxDate: current_month,
icons: {
close: 'textclass1'
}
});
});
Css:
.textclass1::before {
content: "Close";
}
I have this code in html (notice the numers 1 and 2in the outside and inside elements):
<div class="list_item" id="item_1">
<div class="list_item_int">My first line</div>
<div class="eval_buttons">
<div class="approve" id="1"></div>
<div class="dismiss" id="1"></div>
</div>
<div class="list_item" id="item_2">
<div class="list_item_int">My second line</div>
<div class="eval_buttons">
<div class="approve" id="2"></div>
<div class="dismiss" id="2"></div>
</div>
Then I have this script:
$().ready(function(){
$(".approve").click(function(){
$.post(
"php/judge_work.php",
{action : "1", work_info : this.id},
function(data){
$("#item_" + this.id).hide("slow");
}
);
});
$(".dismiss").click(function(){
$.post(
"php/judge_work.php",
{action : "0", work_info : this.id},
function(data){
alert(data);
}
);
});
});
Is there a way to make $("#item_" + this.id).hide("slow"); work? thanks on your kind response.
You can use .closest(), like this:
$(this).closest(".list_item") //gets the ancestor <div class="list_item">
In your case since this won't be the clicked element in the $.post() callback, it'll look like this:
$(".approve").click(function(){
var li = $(this).closest(".list_item");
$.post(
"php/judge_work.php",
{action : "1", work_info : this.id},
function(data){
li.hide("slow");
}
);
});
