jquery ui autocomplete js error on keydown - autocomplete

i've included the jquery ui automcomplete plugin into the following structure:
<li class="search">
<input type="text" class="searchfield" name="searchfield" value="Search for Products" />
</li>
my javascript for this input field looks like:
<script type="text/javascript">
function addSearchFieldFunctionality() {
var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Perl",
"PHP",
"Python",
"Ruby",
"Scala",
"Scheme"
];
$('.searchfield').each(function () {
$(this).autocomplete({
source: availableTags,
minLength: 1
}).data("autocomplete")._renderItem = function(ul, item) {
//console.log(item);
var a = $('<a>', {
href: item.value,
text: item.label,
"class" : "mySearchClass"
});
var b = $('<a>', {
href: item.value,
text: "Add", style: "float:right"});
var $li = $('<li></li>', {style:"width:100%"});
return $li.add(a).appendTo(ul);
};
});
}
</script>
I'm loading that function on document ready. for some reason, if a start typing e.g. the first three letters of a item, i get a resultlist. as soon as i push the keydown push button on the keyword, i get the following error in the chrome (latest version) console:
Uncaught TypeError: Cannot read property 'top' of null
a.widget.activate jquery-ui.min.js:12
a.widget.move jquery-ui.min.js:12

a.widget._create.element.addClass.attr.attr.bind.bind.d jquery-ui.min.js:12
f.event.dispatch jquery-1.7.1.min.js:3
f.event.add.h.handle.i
i'm using version 1.7.1 of jQuery and Version 1.8.12 of jquery UI
On the demo page of jquery ui autocomplete the keydown works well.
Any ideas what's going wrong with my constellation?
It doesn't make a difference to use remote or local data.
Best regards,

I really can make your code working. So I tried to rewrote it in a more simplier way. The problem is render functions only accept strings, not html element. So I add a listener to render the list after its generation (fired on keydown() event).
My thought is you are doing it the wrong way.
why adding another class on those items ? they have already one, so they can be styled.
why transforming them into a nodes ? just add a click() event on them
Could you explain your functional goal ?
// Your list of links
var redirectLinks = {'Ruby': '1234.com', 'Asp': '1235.com'};
function redirect(url) {
// TODO implement window.location=url or whatever you like
if(redirectLinks[url] != undefined) {
alert('redirecting to '+url+' => '+redirectLinks[url]);
}
}
$('.searchfield').each(function () {
$(this).autocomplete(availableTags, {
minLength: 1,
change: function(event, ui) {
console.log('this change event doesnt seem to be fired');
},
select: function(event, ui) {
console.log('this select event doesnt seem to be fired');
}
});
// After the list construction
$(this).keyup(function(e){
if (e.which == 13) { // typing enter validates the input => autocompletechange
console.log('validating input '+$(this).val());
redirect($(this).val());
}
var $list = $('.ac_results:first ul').find('li');
$list.click(function() { // adding an event on suggestion => autocompleteselect
console.log('clicking on suggestion '+$(this).text());
redirect($(this).text());
});
});
});

Bootstrap-vue modal manipulate ok-disabled state in function

I've set the default OK Button in a Bootstrap-Vue Modal to disabled true and want to change it when inputing something in ab-form-input. Calling the function works but disabling ok-disabled not. Can't get access to the property. Seems to be a very basic question but in the component docs in bootstrap-vue there is only the infor that state can be changed (true-false) but not how to manipulate via script.
`
<template>
<b-modal
id="component-modal"
title="Add Component"
#ok="handleOk"
:ok-disabled="true"
>
<div class="container">
<b-row>
<b-col>Component: </b-col>
<b-col>
<b-form-input
v-model="component"
id="new-component"
required
#input="enableOK"
></b-form-input>
</b-col>
</b-row>
</div>
</b-modal>
</template>
<script>
import axios from 'axios';
import store from '../../store';
export default {
data() {
return {
count: 0,
};
},
methods: {
handleOk() {
this.handleSubmit();
},
handleSubmit() {
this.insertComponentClass(this.component, store.state.project);
delete this.component;
},
insertComponentClass(componentClass, pid) {
const path = `${store.state.apiURL}/componentclass/add`;
const payload = {
name: componentClass,
project_id: pid,
};
axios
.put(path, payload)
.then(() => {
this.$parent.getComponents();
})
.catch((error) => {
console.error(error);
});
},
enableOK() {
console.info('enable ok fired');
this.ok-disable = false; // doesnt wor, linter says "Invalid left-hand side in assignment expression"
},
},
};
</script>
`
There's a few things going on here that are incorrect.
You're binding the ok-disabled prop to a hardcoded value of true in your template. If you want that value to change, you'll need to bind it to a variable that you can update in your components <script>
For example, you can update the modal's :ok-disabled prop to:
:ok-disabled="okDisabled"
Then in your <script> data function, add it to the return object (defaulted to true):
data() {
return {
count: 0,
okDisabled: true,
}
}
Now the modal's :ok-disabled property is bound to that variable and we can change the value in the enableOk method like so:
this.okDisabled = false;
Note regarding the lint error, the name of the variable you're trying to assign to this.ok-disable is not a valid variable name. You can't use a dash (-) character for a Javascript variable name. You can rename it to the property we created earlier this.okDisabled

Bootstrap-vue: Auto-select first hardcoded <option> in <b-form-select>

I'm using b-form-select with server-side generated option tags:
<b-form-select :state="errors.has('type') ? false : null"
v-model="type"
v-validate="'required'"
name="type"
plain>
<option value="note" >Note</option>
<option value="reminder" >Reminder</option>
</b-form-select>
When no data is set for this field I want to auto-select the first option in the list.
Is this possible? I have not found how to access the component's options from within my Vue instance.
your v-model should have the value of the first option.
example
<template>
<div>
<b-form-select v-model="selected" :options="options" />
<div class="mt-3">Selected: <strong>{{ selected }}</strong></div>
</div>
</template>
<script>
export default {
data() {
return {
selected: 'a',
options: [
{ value: null, text: 'Please select an option' },
{ value: 'a', text: 'This is First option' },
{ value: 'b', text: 'Selected Option' },
{ value: { C: '3PO' }, text: 'This is an option with object value' },
{ value: 'd', text: 'This one is disabled', disabled: true }
]
}
}
}
</script>
You can trigger this.selected=${firstOptionValue} when no data is set.
what if we don't know what the first option is. The list is generated?
if you have dynamic data, something like this will work.
<template>
<div>
<b-form-select v-model="selected" :options="options" />
<div class="mt-3">Selected: <strong>{{ selected }}</strong></div>
</div>
</template>
<script>
export default {
data() {
return {
selected: [],
options: [],
};
},
mounted: function() {
this.getOptions();
},
methods: {
getOptions() {
//Your logic goes here for data fetch from API
const options = res.data;
this.options = res.data;
this.selected = options[0].fieldName; // Assigns first index of Options to model
return options;
},
},
};
</script>
If your options are stored in a property which is loaded dynamically:
computed property
async computed (using AsyncComputed plugin)
through props, which may change
Then you can #Watch the property to set the first option.
That way the behavior of selecting the first item is separated from data-loading and your code is more understandable.
Example using Typescript and #AsyncComputed
export default class PersonComponent extends Vue {
selectedPersonId: string = undefined;
// ...
// Example method that loads persons data from API
#AsyncComputed()
async persons(): Promise<Person[]> {
return await apiClient.persons.getAll();
}
// Computed property that transforms api data to option list
get personSelectOptions() {
const persons = this.persons as Person[];
return persons.map((person) => ({
text: person.name,
value: person.id
}));
}
// Select the first person in the options list whenever the options change
#Watch('personSelectOptions')
automaticallySelectFirstPerson(persons: {value: string}[]) {
this.selectedPersonId = persons[0].value;
}
}

jsTree - cannot create new node - all other functions work well

Deselect and hover funcntions work fina but create/delete/rename don't.
What do is do wrong?
info.json contains 5 nodes marked from 1 to 5.
<head>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<link rel="stylesheet" href="jstree\dist\themes\default\style.min.css" />
<script src="jstree\dist\jstree.js"></script>
<script>
$(function() {
$('#test_tree').jstree({
'core' : {
'data' : {
'url' : 'info.json',
'data' : function (node) {
return { 'id' : node.id };
}
}
}
});
});
</script>
</head>
<body>
<div id="container" >
<div id="nav_bar">
<button id="create" onclick = "demo_create()">Create</button>
</div>
<div id="test_tree"></div
</div>
<script>
function demo_create() {
$.jstree.reference('#test_tree').hover_node('ajson5');
$.jstree.reference('#test_tree').deselect_node('ajson1');
$.jstree.reference('#test_tree').create_node();
};
</script>
</body>
I used same example from official site but it doesn't work
Thanks for any help.
First, in order for changes to be made to the tree, checkcallback in core config need to be set to true.
$('#test_tree').jstree({
'core' : {
'data' : {
'url' : 'info.json',
'data' : function (node) {
return { 'id' : node.id };
},
check_callback : true
}
}
You need to at least pass the parent.id to the create_node function.
$.jstree.reference('#test_tree').create_node('ajson1');
You could check the API at the jstree website for the full parameter list.
Demo jsTreeView 3.2.1 version
$("#treeView").jstree({ 'core': {
'check_callback': true,
'themes': {
"variant": "large"
},
'data':
[{"id":"1","parent":"#","text":"Parent Node"}]
}
});
You are missing the single quotation mark for the check_callback, after using that it will work. e.g. 'check_callback': true.
Code to create new Node
var ref_treeview = $("#treeView").jstree(true);
sel = ref_treeview.get_selected();
if (!sel.length) {
return false;
}
sel = sel[0];
sel = ref_treeview.create_node(sel, "childNode", "last", CreateNode,true);
Here CreateNode is my Callback function name
you have to send the selected element.
use the following (this is basically the code of the create button in the demo page http://www.jstree.com/demo/):
var tree = $("#test_tree").jstree(true);
var sel = tree.get_selected();
if (!sel.length)
{
return false;
}
sel = sel[0];
sel = tree.create_node(sel);
if (sel)
{
tree.edit(sel);
}
At the time when you create the jstree instance you just need to configure the
'core' setting as shown bellow:
$(function () {
$('#jstree').jstree({
'core':{check_callback : true}
});
You have to set the type of the newly created node like so:
$('#tree').jstree().create_node('#', {'id': 'blah', 'text': 'new node', 'type': 'folder'}, 'last', function() {
console.log('done');
});
jstree documentation should be improved.
using code from the other answers, I was able to make the following work:
Please note, this actually works. I am using it to create menus for an external ajax API.
function makeNode(menunode, menuname){
var inst = $.jstree.reference("#treemenu"); //get menu instance
var obj = inst.get_node(menunode);
inst.create_node(obj, menuname); //creates nodes. use "#" to make root nodes
inst.open_node(obj); // open the node (unfold)
});
usage:
//create menu instance and allow tree changes
$('#treemenu').jstree({'core' : {'check_callback': true}});
makeNode("#", "main menu"); //makes root node
makeNode("#j1_1", "submenu in main menu"); //makes sub node
this is assuming that you have a div with id="treemenu" thusly
<div id="treemenu"></div>

upload file in add/edit from of jqgrid?

How to implement AutoCompleteExtender OnclientPopulated behaviour?

I am trying to implement an autocomplete list using the Ajax toolkit: AutoCompleteExtender
How to achieve the following behaviours using Ajax toolkit: AutoCompleteExtender?
Can provide any code examples also?
Like google search, when the autocomplete list if display base on the inputs. When the mouse is move out or focus on other area. The autocomplete list is still showing base on the input value.
If user enter abc and system display autocompletelist like abcd, abcde. When user move the mouse out and then click back the same input abc system should again display the autocomplete list.
Can anyone advise?
I personally prefer using jQuery UI Autocomplete.
Demo & Code:
jQuery UI Autocomplete
Sample JS Code:
$(function() {
function log( message ) {
$( "<div>" ).text( message ).prependTo( "#log" );
$( "#log" ).scrollTop( 0 );
}
$( "#city" ).autocomplete({
source: function( request, response ) {
$.ajax({
url: "http://ws.geonames.org/searchJSON",
dataType: "jsonp",
data: {
featureClass: "P",
style: "full",
maxRows: 12,
name_startsWith: request.term
},
success: function( data ) {
response( $.map( data.geonames, function( item ) {
return {
label: item.name + (item.adminName1 ? ", " + item.adminName1 : "") + ", " + item.countryName,
value: item.name
}
}));
}
});
},
minLength: 2,
select: function( event, ui ) {
log( ui.item ?
"Selected: " + ui.item.label :
"Nothing selected, input was " + this.value);
},
open: function() {
$( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
},
close: function() {
$( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
}
});
});
Your first point is the ajax ACE (Auto Complete Extender) default behavior.
the second one, you can use jquery .mouseleave() and .mouseenter() event to shave your contextKey in a hidden field on mouse leave and fill it again in mouse enter.
