I am trying to trigger an event when an input textbox changed:
$('.packeta-selector-branch-id').on('change', function () { alert('helo'); })
This works only If I manually type something in the textbox, but in my case where an external javascript is setting the textbox value, not working.
I created a little jsfiddle to show this:
https://jsfiddle.net/6vnuqxa0/
To try out:
Click on Choose pickup point
Select something from list and click on "Choose this pick up point".
Any ideas how to resolve this issue?
The selected answer to jQuery watch for domElement changes? suggests binding to the DOMSubtreeModified event. I have tried iin your fiddle and it works! The answer does mention that this event may be deprecated, but it is worth looking into.
In your case, add an id to your div so that you have:
<div id="packeta-selector-branch-id" class="packeta-selector-branch-id"></div>
Then the following code will trigger the alert when the contents of that div change.
$('#packeta-selector-branch-id').bind('DOMSubtreeModified', function(e) {
if (e.target.innerHTML.length > 0) {
alert('helo');
}
});
Otherwise, I would look at the widget itself and try and determine if it fires any events on select. If so, you could attach some behaviour to that event.
trigger('change') when click button. but a ID or name on your input would be better
$(document).off('click', '.button select-branch').on('click', '.button select-branch', function(){
$('.packeta-selector-branch-id').trigger('change');
})

I have a page with a asp:textBox.
In my code behind (VB.net) in the Page Load, depending on such filters, i'm going to enable/disable this asp:textBox in this way:
this.txtB.Enabled = true;
this.txtB.Enabled = false;
In the moment that the user change the context of this asp:Textbox (only if it's enabled) i want to do some stuff, and so i thought to use jQuery in this way:
$('.txtB:enabled').on("propertychange input paste", function () { ... });
The problem is that, in some cases, the textBox that in the beginning was disabled had to become enabled too. And i do that always in jQuery:
$(".txt_PISocAppNom").prop('disabled', false);
But in this case when then the user change the context of the textBox, the previous method didn't catch the changes.
I assume that the problem derive from the fact that in my code behind i'm setting the ENABLE attribute and in jQuery the DISABLE attribut.
I don't know if my supposition is correct and in that case how to change the code to make it work.
Have you tried using 'live' instead of 'on'?
$('.txtB:enabled').live("propertychange input paste", function () { ... });
If your textbox is disabled at the beginning the selector '.txtB:enabled' won't apply to it so the change event will not get attached to it. Using 'live' will make sure that the event also gets attached for the future elements.
'live' has been deprecated in the new versions of jquery. In jquery 1.7+ you can also use $('.parentB').on("propertychange input paste", ".txtB:enabled", function () { ... }); to get the same result as 'live'. I'm using '.parentB' as a selector to get the parent of your textbox.
The problem was that i inserted the
$(".txtB:enabled").on("propertychange input paste", function () { ... });
in the
$(document).ready(function () { ... });
In that case, it was attacked in the early stages only to those items that were enabled. So, if my textbox was at first disabled, and enabled only later it hadn't the .on(...) property.
Here's my situation: I've got a field that once the user double click, it'll edit the field. That's fine and working. I've got two functions: ok and cancel. Cancel disables the editing mode. ATM, the user has to click cancel to disable the editing mode. What I'd like to is to allow the editing mode to be disabled when the user clicks anywhere else on the page. How can I accomplish this with Angular?
EDIT: I'm adding my markup (Note: this is Jade):
tr(ng-repeat="user in users | filter:searchText"s)
td(ng-dblclick="editItem(user)", hm-double-tap="editItem(user)", ng-blur="cancelEditing()")
span(ng-hide="user.editing") {{user.name}}
form(ng-submit="doneEditing(user)", ng-show="user.editing", class="inline-editing-2", ng-blur="cancelEditing()")
input(type="text", class="form-control", ng-model="user.name")
button(class="btn btn-success mr-1", ng-show="user.editing", ng-click="doneEditing(user)")
span(ng-click="doneEditing(user)").fa.fa-check-circle
button(class="btn btn-warning mr-1", ng-show="user.editing", ng-click="cancelEditing(user)")
span(ng-click="cancelEditing(user)").fa.fa-times-circle
As you can see, I've got a hg-repeat on user. When double click on the td element it makes user.editing true so the form shows up. the cancelEditing(user) makes the variable false and only the field is displayed.
I've added ng-blur="cancelEditing()" on thetr,td,spanandform` and none of it worked.
Any ideas what am I missing?
Use ng-blur to bind your cancel event to the element. It will fire when the element loses focus.
IE: <input ng-blur="cancel()" />
Note: The cancel function must be within scope.
Angular ngBlur Docs
Update from comments:
Give the input element focus when your double tab event fires making the field editable. Your blur event is likely not firing because the input element never had focus.
You could do this from inside your editItem function or from inside the directive.
As an example:
yourApp.directive('hmDoubleTap', function(){
return function(scope, element, attr){
if(doubleTap) {
// Fire editItem(user)
// You could add your .focus() inside editItem().
// Or focus the first input element at the end of the directive.
element.find("input")[0].focus();
}
};
});
b1j's answer would work only if the element gains focus. Does hm-double-tap directive focuses the element after double click? If not you will have to trigger focus in editItem function.
Another approach would be to handle the click event on any other element like this:
$('#field-no-edit').click(function() {
$(this).hide();
$('#field-edit').show().focus();
});
$('body').on('click', function(e){
console.log($(e.target).attr('id'));
if ($(e.target).attr('id') != 'field-no-edit') {
console.log('not');
$('#field-no-edit').text($('#field-edit').val());
$('#field-edit').hide();
$('#field-no-edit').show();
}
});
JSFiddle
So, I have a hidden file input, and multiple clicks open up multiple file input dialogs. So I disable them temporarily like so:
on click:
$("#file_input").click();
$(document).off(event, #parent_click);
on success, on the change event for the file input
$(document).on(event, #parent_click, clickHandler);
HOWEVER! If the user opens up the File Dialog, and then decides to not do anything, and hits cancel, the #parent_click clickHandler can never be turned on again.
How do I rectify this?
If I correctly got it, you can on .change() check for input value and if it's empty just not to fire disable
$('#yourInputId').change(function{
if($('#yourInputId').val() == ''){
//do some stuff
} else {
//do other stuff
}
})
BTW please, could you provide some fiddle next time, if it's possible, it will be much easier to find out a solution with it.
UPDATED working Fiddle
I am trying to restrict the user from clicking on a button multiple times. They can click on the button once when the page loads. If the page is reloaded the same should apply the user can click on the button only once.
I am using the following code however it doesn't seem to work for me
$("#doAccess").click(function() {
$("#doAccess").removeAttr('onclick');
DoSave();
});
Disable the button after it's been clicked
var accessBtn = $('#doAccess');
accessBtn.click(function() {
accessBtn[0].disabled = true;
DoSave();
});
Sounds like what you really need is:
$("#doAccess").one('click', DoSave);
jsFiddle example
.one() - Attach a handler to an event for the elements. The handler is executed at most once per element per event type.
Why not this?
$("#doAccess").once('click', function() {
DoSave();
});
You should probably also gray out or disable #doAccess, whatever it is.
First, sorry for my bad English.
I'm making a Coupons site and have trouble with selecting and deselecting the coupons. Each coupon is in a DIV 'box' in which there is a checkbox.
I made a onClick function on the DIV box (so the user can select the coupon by clicking on anything inside the DIV box. What I need now is, when the user want to deselect the coupon (by clicking on the checkbox inside the DIV box), I need to 'override' the DIV's onClick function (execute the checkbox onClick event, not the DIV's onClick event).
I know that everyone prefers some code as an example, but the question/problem is simple and I don't think you need all of my un'useless code inside the events/functions :)
Thanks :)
It seems like you want stopPropagation if the checkbox is being unchecked: http://jsfiddle.net/8Dcq8/.
$("div").click(function() {
alert("add"); // clicking anywhere in div to add coupon
});
$(":checkbox").click(function(e) {
if(!this.checked) { // if unchecking, remove coupon
alert("remove");
e.stopPropagation(); // don't run parent onclick
}
});
If the <div> click handler looks something like this:
var $boxes = $('div.box');
$boxes.on('click', function ()
{
// do whatever to select the coupon
});
Then the checkbox handler should look something like this:
$boxes.find('input[type="checkbox"]').on('click', function (event)
{
event.stopPropagation();
// do whatever to deselect the coupon
});
See event.stopPropagation().
You have to cancel bubbling. See here for an explanation.
You can use the jQuery Alternative, or create sub-elements with onClicks that don't target your checkbox. you might be able to use something like this also.
document.getElementById('element').checked.onreadystatechange=function(){
//code
}
good luck
