Without using any Javascript framework or Class, I am working with pure Javascript and Ionic 5 .
I am trying to display the alert notification when the user hit the Add button
If the User does not fill the fields and then press the ADD Button, an alert pops out to notify the user to fill the fields
Note: Add button its function also is to Add two fields
The issue is when Hit the Add button, No notification pops out
here is the code
HTML section
<ion-alert-controller></ion-alert-controller>
In app.js file
const btnConfirm = document.querySelector('#btn-confirm');
const alertCtrl = document.querySelector('ion-alert-contrller');
btnConfirm.addEventListener('click' ,() => {
const enterReason = reasonInput.value;
const enterInput = parseFloat(amountInput.value).toFixed(2);
if(enterReason.trim().length <=0 || enterInput <= 0 || enterInput.trim().length <=0
) {
async function handleButtonClick() {
const alert = await alertController.create({
message: 'Please enter valid reason and amount!',
header: 'Invalid Inputs',
buttons: ['Okay']
});
await alert.present();
}
return; // if values are Invalid - stop execution
You should do somethign like:
const btnConfirm = document.querySelector('#btn-confirm');
btnConfirm.addEventListener('click' ,() => {
const enterReason = reasonInput.value;
const enterInput = parseFloat(amountInput.value).toFixed(2);
if(enterReason.trim().length <=0 || enterInput <= 0 || enterInput.trim().length <=0) {
presentAlert(); // call your alert function when input is invalid
return;
}else{
// continue execution
}
})
// keep your alert as a function. and call it when ever you want.
async function presentAlert() {
const alert = document.createElement('ion-alert');
alert.cssClass = 'my-custom-class';
alert.header = 'Alert';
alert.subHeader = 'Subtitle';
alert.message = 'This is an alert message.';
alert.buttons = ['OK'];
document.body.appendChild(alert);
await alert.present();
const { role } = await alert.onDidDismiss();
console.log('onDidDismiss resolved with role', role);
}
my code is :
function autocomplet() {
var min_length = 0; // min caracters to display the autocomplete
var keyword = $('#country_id').val();
if (keyword.length >= min_length) {
$.ajax({
url: 'ajaxname.php',
type: 'POST',
data: {keyword:keyword},
success:function(data){
$('#country_list_id').show();
$('#country_list_id').html(data);
}
});
} else {
$('#country_list_id').hide();
}
}
function set_item(item) {
// change input value
$('#country_id').val(item);
// hide proposition list
$('#country_list_id').hide();
}
and i wana hide ul (country_list_id) when user click on anywhere ?
and im not good in ajax :(
so any one can edit this code
Assuming you just want to hide the id when the user click basically anything.
Then here.
$(document).on("click", () => {
$('#country_list_id').hide();
})
I have been changing a form based on REACT and this is something I am a newb with (been using it already for 4 months but just segments of it, sometimes actual progress with the programming is based on pure luck and every time on advices of good people found here).
Currently I have a task of re-developing a form of this look:
What I need to achieve is Calibration radios' behavior based on Type's selection: if argument calibration is set to 0 (zero) then disable option 'Accredited' and check second option automatically.
Edited: 19 Oct 2017
This creates the drop down, and the DD works great:
createSuggestInput(name) {
const { id, value, labels } = this.props;
const _t = this.props.intl.formatMessage;
var options = [
{ value: 'one', label: 'One', calibration: '0' },
{ value: 'two', label: 'Two ', calibration: '1' },
{ value: 'three', label: 'Three', calibration: '0' },
{ value: 'four', label: 'Four', calibration: '1' },
];
return <Select.Creatable
name = {`${id}_${name}`}
value = {this.state.brandSelect}
placeholder = {_t(translations.txtSuggest)}
options = {options}
onChange = {this._onChange.bind(this)}
label = {labels[name]}
key = {`${id}_${name}`}
promptTextCreator = { (label) => _t(translations.txtCreate) + ' ' + label + _t(translations.txtCreateEnter) }
/>;
}
When selected option's calibration value is ZERO, I need to update set of Calibration radio buttons, by disabling the option "Accredited" and at the same time checking the second option, "Not Accredited".
createRadioCalibration(name) {
const { id, value, labels } = this.props;
const _t = this.props.intl.formatMessage;
const ACCREDITATION_TYPES = [
[CALIBRATION_ACCREDITED, _t(messages.calibrationAccredited)],
[CALIBRATION_NOT_ACCREDITED, _t(messages.calibrationNotAccredited)]
];
return <FormChoiceGroup
type = "radio"
values = {ACCREDITATION_TYPES.map(mapValueArray)}
key = {`${id}_${name}`}
name = {`${id}_${name}`}
value = {value[name]}
handleChange = {this.handleFieldChangeFn(name)}
/>;
}
These two are rendered as follows:
render () {
const FIELDS = {
[CALIBRATION]: this.createRadioCalibration(CALIBRATION),
[TYPE]: this.createSuggestInput(TYPE),
};
return (
<div className="repair-form-device repair-form-device-field-row">
<div className="repair-form-device-id">
{id + 1}
</div>
<div className="clearfix repair-form-device-content">
<div className="">
{ FIELDS[TYPE] }
</div>
<div className="">
<label>{_t(messages.repair)}</label>
{ FIELDS[CALIBRATION] }
</div>
.....
And lastly the _onChange function:
_onChange(tool) {
const { id } = this.props;
this.setState({
brandSelect: tool
});
}
As I stated previously, I am stuck with the main task, which is manipulating the Calibration radio buttons.
I believe I can update its status inside the _onChange function, but everything I tested so far lead me nowhere.
Your patience is much appreciated!
I would like to be able to use the numericRefinementList to allow users to pick the distance from themselves an item can be? This would be using the IP geo-location feature or inputting the geo-location from browser if available.
Less than 50km
50 - 100km
100 - 150km
More than 150km
https://community.algolia.com/instantsearch.js/documentation/#numericrefinementlist
This is unfortunately not something you can do with the numericRefinementList but you can probably build a custom widget setting the aroundRadius depending on the link you've clicked on:
function radiusList(options) {
if (!options.container) {
throw new Error('radiusList: usage: radiusList({container, ...})');
}
var $container = $(options.container);
if ($container.length === 0) {
throw new Error('radiusList: cannot select \'' + options.container + '\'');
}
return {
init: function(args) {
// event delegation: set the aroundRadius of the underlying link
$(document).on('click', '.radius-link', function(e) {
e.preventDefault();
args.helper.setQueryParameter('aroundRadius', +$(this).data('radius'));
args.helper.search();
});
},
render: function(args) {
// FIXME: display the list of radius links
var html = '<ul>';
html += '<li>< 100km</li>';
html += '</ul>';
$container.html(html);
}
};
}
And then you use it with:
search.addWidget(radiusList({container: '#my-radius-list'}));
Everything I try just does nothing, no errors, message, really anything. So I have three tabs, the first being a login tab, each tab has its own .js code, so for example, the login has its own login.js. Now, I use the httpClient to authenticate back to our website, and now want to remove the login tab and display the other tabs, cannot get it to work for the life of me, I can now remove the login tab but cannot load ay of the other tabs. Driving me nuts because I am finding 20 examples but they either don't separate the tabs into their own .js files or the example just plain doesn't work for me. Help! This seems so basic but yet...

I think that's all you'd need to see, the login.js has my latest attempt but I've tried things like tabGroup.open({url : 'app.js'}) and about three our four other option. Thanks.
You may want to add this eventListener to your app.js where the tabGroup is.
You can then fire a "app:gotoTab" event from anywhere.
app.js
Ti.App.addEventListener('app:gotoTab', function(e) {
tabGroup.setActiveTab(e.tab);
});
login.js
// tab index starts with 0, so 0 is your first tab
Ti.App.fireEvent('app:gotoTab', { tab: 0 });
Simply Copy paste this code
Login.js
var win = Titanium.UI.currentWindow;
var appUrl = "http://localhost:3001/ticket_agents/sign_in";
var email = Titanium.UI.createTextField({
color:'#336699',
top:10,
left:10,
width:300,
height:40,
hintText:'Email',
keyboardType:Titanium.UI.KEYBOARD_DEFAULT,
returnKeyType:Titanium.UI.RETURNKEY_DEFAULT,
borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED
});
win.add(email);
var password = Titanium.UI.createTextField({
color:'#336699',
top:60,
left:10,
width:300,
height:40,
hintText:'Password',
passwordMask:true,
keyboardType:Titanium.UI.KEYBOARD_DEFAULT,
returnKeyType:Titanium.UI.RETURNKEY_DEFAULT,
borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED
});
win.add(password);
var loginBtn = Titanium.UI.createButton({
title:'Login',
top:110,
width:90,
height:35,
borderRadius:1,
font:{fontFamily:'Arial',fontWeight:'bold',fontSize:14}
});
var loginReq = Titanium.Network.createHTTPClient({
onload : function(e) {
var json = this.responseText;
var response = JSON.parse(json);
Ti.API.info("Received text: " + this.responseText);
if (response.id > 0)
{
alert("login Success");
tabGroup.setActiveTab(2);
}
else
{
alert("Unknown login error");
}
},
onerror : function(e) {
var response = this.responseText;
Ti.API.debug(e.error);
alert('error: ' + this.responseText);
},

Hey Ross, You always remember window.close work on child Window perfectly.
In this application. You can use single Window base Application.
If, In First Window Login Successfully then, you can OPEN Second child Window.
for more details you can use KICHEN Shink Example. this is very useful for You.
You may want to redesign your UI. The Apple Human Interface Guidelines specifically say that you shouldn't programmatically switch tabs or add/remove tabs. They expect that a tabgroup should only be controlled by the user once you put it in front of them.
If the user needs to log in before they can use other features of your app you can present the a login window before the window with the tab group. Otherwise, you should replace the content of the login tab with something else after a successful login, perhaps with user profile information or some instructions.
