To generate textbox dynamically
buffer += "<tr><td>" + nomen_list.getName() + "</td><td><input type='text' style='width:50px' class='n_val' id=" + nomen_list.getId() + "-" + nomen_list.getCat() + " value=" + nomen_list.getVal() + " /></td></tr>";
I getting dynamically textbox, but focusout is not working for dynamically generated textbox, whereas same page has some textbox, which is hard-coded for that, above script gets triggered.
$(window).load(function() {
$(document).on('focusout','.n_val',function() {
alert(this.id);
});
});
Instead of using document you could use the text box's closest parent id or class. I have no idea of your html layout, hence using document. Also see jQuery on.
$(document).on("focusout", ".n_val", function(){
alert("hi");
});
Try this:
$(document).ready(function() {
$(document).on('focusout','.n_val', function() {
alert(this.id);
});
});
$(document).on('focusout', '#randmSubstationTable tbody tr td', function () {
$('#randmSubstationTable tbody tr td')
.focusout(function(){
$(this).parent().parent().children().index($(this).parent());
});
});
You should call focusout AFTER every textbox is added to the DOM. Here you are probably calling it too soon (at load event, which probably occurs before you add the dynamic textboxes)

I am using this code for the click handling on a button inside my page:
$(document).on("click", $('#' + GlobalVariables.currentUserType).find(".addDocumentToSection"), function (e) {
addItemToDocumentGrid();
$('#removeDocumentFromSection').disable(true).addClass("disabled");
$('#removeSelection').disable(true).addClass("disabled");
});
But the event fires as soon as I click anywhere in the page. Even if it is not the supposed button which I want to select with $('#' + GlobalVariables.currentUserType).find(".addDocumentToSection").
$('#' + GlobalVariables.currentUserType).find(".addDocumentToSection") returns one element which is actually the button which I want to be selected.
Why does it behave like that?
If you want to use event delegation, the second argument should be a selector, not a jQuery object.
$(document).on("click", '#' + GlobalVariables.currentUserType + " .addDocumentToSection", function (e) {
// ---------------------^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
addItemToDocumentGrid();
$('#removeDocumentFromSection').disable(true).addClass("disabled");
$('#removeSelection').disable(true).addClass("disabled");
});
If you don't want to use event delegation, you need to call on on the element you want to hook the event on:
$('#' + GlobalVariables.currentUserType).find(".addDocumentToSection").on("click", function (e) {
addItemToDocumentGrid();
$('#removeDocumentFromSection').disable(true).addClass("disabled");
$('#removeSelection').disable(true).addClass("disabled");
});
This is all covered in the on documentation.
You are attaching onClick event to a document element. Try:
var button = $('#' + GlobalVariables.currentUserType).find(".addDocumentToSection");
button.on("click", function() {
addItemToDocumentGrid();
$('#removeDocumentFromSection').disable(true).addClass("disabled");
$('#removeSelection').disable(true).addClass("disabled");
});
$('#' + GlobalVariables.currentUserType).find(".addDocumentToSection").on("click", function(e){
});
jQuery can use selectors before the .on("click", this should work for you.
So I have multiple delete buttons on a table and each button has there own unique id. I am trying to get this value via javascript but I can't get it to work at all.
Here is a section js that is working properly and loads the correct html (this is ran for each movie):
function createRow(movie) {
movie.NewDate = new Date(movie.ReleaseDate);
return '<tr><td><img class="movieImage" src="' +
movie.ImageLink +
'" alt="' +
movie.Title +
' Image" style="width:50px;height:75px">' +
'<td>' +
movie.Title +
'</td><td>' +
movie.NewDate.toLocaleDateString("en-US") +
'</td><td><button type="button" class="removeButton" value="' + movie.DVDID + '">Delete</button></td></tr>';
}
And here is the js where I am trying to retrieve the id:
$(document)
.ready(function () {
var deleteButtons = $(".removeButton");
deleteButtons.each(function (index) {
var currentButton = $(this);
var buttonValue = currentButton.val();
currentButton.click(function () {
alert(buttonValue);
});
});
});
I found the last snippet via Click one of multiple buttons, put value in text input
Right now just getting a proper alert would be sufficient.
Have you tried this approach:
$("#tableId").on("click", ".removeButton", function(){ alert($(this).attr("value")); })
This "on" binds all the ".removeButton" elements with the given function when click is triggered.
Your javascript should look like this:
$(document).ready(function () {
var deleteButtons = $(".removeButton");
deleteButtons.on('click', function() {
alert($(this).attr('value'));
});
});
Also, since you adding these buttons dynamicly with javascript, you may need to rebind button click events after you add new row. Also binding should be done after loading button html to DOM.
Since you are creating buttons dynamically, you won't be able to reach them properly because when the javascript was initiated they didn't exist in the DOM. So in order for you to be able to find the buttons, you'll have to look at the document scope and then find which button (class) you click on, like so:
$(document).on('click', '.removeButton', function(){
console.log($(this).val())
})
See fiddle for complete example
The solution may be obvious, but when clicking the .remove element, I am trying to remove the entire .tag element that is the parent. Currently, clicking the .remove element has no response.
HTML
'<div class="tag"><input id="' + id + '" type="hidden" name="' + name + '" value="' + value + '" />' + input + '<i class="remove dismiss fa fa-remove"></i></div>'
JS
$('.remove').on('click', '.remove', function() {
$(this).parent().remove();
});
Try this : As you are adding remove link dynamically, you need to register click handler using .on(). But in your case you have error in using .on(). Please use below code.
$(document).on('click', '.remove', function() {
$(this).parent().remove();
});
More Information on jQuery .on()
You can try this:
http://jsfiddle.net/myyzrwwe/
$('.remove').on('click', function() {
$(this).parent().remove();
});
You shouldn't always use delegate the event to the same element that has been delegated. You need to select a static parent. In my example, the document object is the parent of everything.
$('body').on('click', '.remove', function() {
$(this).parent().remove();
});
The problem might be you are binding the event to .remove, if this content is dynamic you might have a problem. Its better, in those cases, to bind to document.
$(document).on()
The callback has the event parameter, use that to remove.
function(e) {
$(e.currentTarget).parent().remove();
}
Check if you undelegate elements.
I am adding extra selects and text fields to a form using jQuery. However I want to be able to remove added text fields using the remove button.
Once a field has been added jQuery can not seem to detect it.
jQuery
var counter = 2;
$("#addButton").click(function () {
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'contact-list-div-' + counter).attr("class", 'contact-list-div');
newTextBoxDiv.after().html('<select></select>' +
'<input type="text" name="textbox' + counter +
'" id="textbox' + counter + '" value="" >' + '<button type="button" class="removeButton" id="removeButton-' + counter + '">Remove Button</button>');
newTextBoxDiv.appendTo("#contact-list");
counter++;
});
$(".removeButton").click(function() {
alert(this.id); //this never shows, only on the element that was
//added directly added using html, in this case removeButton-1
});
HTML
<div id="contact-list">
<div class="contact-list-div" id="contact-list-div-1">
<select></select>
<input>
<button type='button' class='removeButton' id='removeButton-1'>Remove Button</button>
</div>
</div>
<input type='button' value='Add Button' id='addButton'>
$('#contact-list').on('click', '.removeButton', function() {
//Your code
});
You need to use event-delegation:
$(document).on('click', '.removeButton',function() {
$(this).parents('.contact-list-div').remove();
});
You appending content to your DOM after the event-listener for your click on .removeButton is registered. So this element does not exist at the time your binding a click event to it.
Through event-delegation you are able to bind an event-listiner to an existing parent (document in this case, but #contact-list would be working too). And this will listen to all events of its descendants matching the .removeButton - selector.
Demo
This is because you are binding the events to elements that do not yet exist.
Use jQuery delegation to enable handlers on not yet existing elements:
$("body").on("click", ".removeButton", function() {
alert(this.id);
});
You add the click listener only at the first button.
Try using delegate:
$(document).delegate(".removeButton", "click", function() {
alert(this.id);
});
This tells the document that whenever a event click occours on an element with class "removeButton" it should call that callback
(You can see it working here)
Because the element is dynamicly added with jQuery, the normal .click event of jQuery will be not able to detect the new added elements.
Use instead .on. See the example below:
$("body").on("click", ".removeButton", function() {
alert(this.id); //this never shows, only on the element that was
//added directly added using html, in this case removeButton-1
});
<html>
<head>
<script>
$(document).ready(function(){
$("p").click(function(){
$(this).hide();
});
});
function func(){
var s = "<p id=" + id +">"+"<center>"+"<h2><b>Topic :</b></h2>"+message+"</center></p><br>";
document.getElementById("stat").innerHTML+=s;
}
</script>
</head>
<body>
//call function func
<pre id="stat" > </pre>
</body>
</html>
Guys the function func is supposed to create a paragraph with id as "id " and the content as a message inside the tag with id as "stat " .. it works fine
But i cant use the 'Jquery' selector to use the click function on tag :/ !
the reason i am inserting inside in is i need the interpreter to consider "\n" as a new line.
Why is that , not working ?
and is there any other way to do it ?
Try this,
$(document).ready(function(){
$(document).on('click','p',function(){
$(this).hide();
});
});
$(document).on('click', 'p', function() { $(this).hide();})
The code you wrote is not working because the p element is not present when the document is loaded. Since the p element is dynamically added, you have to attach the event to the document object
the fastest way will be to change
var s = "<p id=" + id +">"+"<center>"+"<h2><b>Topic :</b></h2>"+message+"</center></p><br>";
to
var s = "<p id=" + id +" onclick=\"$(this).hide()\">"+"<center>"+"<h2><b>Topic :</b></h2>"+message+"</center></p><br>";
and delete this
$(document).ready(function(){
$("p").click(function(){
$(this).hide();
});
});
This may help:
$('body').on('click', 'p', function(){
$(this).hide();
});
use .on() instead
$(document).on('click', 'p', function(){
$(this).hide();
});
.on() has to ability to add a click handler to elements that are created dynamically , like your <p> tags are
Attach the click event handler inside func:
function func(){
var s = "<p id=" + id +">"+"<center>"+"<h2><b>Topic :</b></h2>"+message+"</center></p><br>";
document.getElementById("stat").innerHTML+=s;
$("#" + id).click(function(){
$(this).hide();
});
}
Or better still:
function func(){
var s = $("<p id=" + id +">"+"<center>"+"<h2><b>Topic :</b></h2>"+message+"</center></p><br>");
$("#stat").append(s);
s.click(function(){
$(this).hide();
});
}
