I need to know how to add an event to a button. The specific issue is that I want to add an event which is a prototype function of a class. Consider the following as an example:
MyTestClass = function() {
this.firstName = "Pete";
this.lastName = "Johnson";
[code]....
I have a <div> containing 3 buttons. The buttons have id's like this:
Button 1: btnFoo
Button 2: btnBar
Button 3: btnBaz
I'd like to add an click event to each button to call a function named [button ID]_click():
i.e.
btnFoo_click()
btnBar_click()
btnBaz_click()
So far I have this:
$("#divButtons button").each(function() {.
$( this ).bind("click",function(){
eval(($(this)[0].id) + '_click()');
});
});
This works but is there a way without having to use eval and still utilizing the lovely .each function?
I have a basic HTML form with a button that submits the form via jQuery's $.post to a processor. That processor returns the identical form, including any errors below any of the elements e.g. input, textarea, etc. The response also has a new submit button to submit the form once more, however, because I'm retrieving a giant string with HTML elements and because jQuery already loaded, that new submit button doesn't do anything. How can I parse jQuery's response for that button and assign a handler so that when the button is pushed, it submits the form again?

Im trying to develop an AJAX application which updates a <select> list with a series of <option> tags when the user makes an entry in a field.
Therefore, my ajax application needs to dynamically create <option> tags and append them to the <select> list on the form. I have got this working in all browsers. However, i do not know how to add an "onclick" event handler to each <option> tag that is dynamically created in my javascript code.
Code:
As you can see, i create an option javascript object for each new <option> tag and add it to the <select> list. This works. But how can i also add an "onclick" event handler in the javascript code?
<label id="mylabel" onclick="myOnclickFunction()">My Label</label>
How to get the "myOnclickFunction()" _string_ with jQuery? JavaScript getAttribute("onclick") works fine, but I want to do it through jQuery.
I try to add a function to be triggered also within an event (which already has a function). I coded it, unfortunatelly one line of the code should be different for IE and Moz. I try to find a common way without using a browser detector... Any ideea? The red line works for Mozilla, the blue one for IE:
function addFunc(){
var e = document.getElementsByTagName('*');
for(var i=0;i<e.length;i++){
if(e[i].getAttribute('onclick')||e[i].getAttribute('onclick')!=null){// Moz || IE
//var f = new Function(e[i].getAttribute('onclick'));
var f = e[i].getAttribute('onclick');
e[i].onclick=function(){f();otherFunction()}
}}} Code:
Is it possible to set an html element's (created through HTML DOM's createElement() method) 'onclick' attribute's value to a Javascript function which requires a parameter, passing a variable to it at the same time?
I have the following Javascript code:
var parentDiv = document.getElementById("subscribers");
var stubSpan = document.createElement("span");
stubSpan.id = "opentok_subscriber_" + stream.streamId;
stubSpan.onclick = showStreamInFullScreenMode(stream);
parentDiv.appendChild(stubSpan);
'stream' in the bolded line is a parameter variable of the function that the above code is in, and I'm trying to pass it to another function using an onclick event.
I have some jQuery.ajax() calls. It'is all the same but success function and I'd like get less code by taking all ajax calls in the same function.But I need one additional parameter I am using later in the success function, for instance.My actual code is like this:
jQuery.ajax(myParam){
...
success: function(responseData){[code]....
But I can't manage to archieve that.
I want to preserve a 16/9 aspect ratio to the window after any resize, making the width a function of the height.
As I have a window.resizeTo() inside the window.onresize event function, the infinite loop is served. How may I quit it?

const c_ra=16/9;
window.onresize = function WindowReSize() {
var myWidth = 0, myHeight = 0;

I can't append click event handler at the <a> element when it is created by jquery on that way...

According to ECMAScript, the root of the prototype chain is Object.Prototype. Each object has an internal property [[Prototype]] that could be another object or NULL.... However, it also says that every function has the Function prototype object: Function.Prototype, it confused me, because a function is an object, for a function object, what is its function prototype and object prototype..For example:
var x = function (n) {return n+1;};
what is the relationships of x, Object.Prototype and Function.Prototype
I am trying to get to the bottom of javascript object, prototypes etc. I have a fairly good grasp of it, but I get confused the closer I get to the base object.prototype. FIrst of all, I was under the impression that all objects descend directly from Object. But some objects (like Array) seem to inherit properties and methods from the function.prototype. So does this mean that the chain is like this:
object -- function -- array Second, I noticed (on the mozilla javascript reference site that object.prototype inherits properties and methods from function.prototype and vice versa!? How can this be? I must be missing something important about understanding the chain?
I have the following javascript function:
[ function addNewWindowEvent(evType, fn)

I've many div with sequence of ids like d1 d2 d3 ... and I need to listen to their click event so I'm using a loop to add an event handler to them, Here it's my code:
for(var i = 0; i < $ds.length; i++){
var $d = $ds[i];
var xFunc = function(e){
document.title = "d: "+$d;
[Code]....
But when I click on each of them always the title goes to "d: 4" where 4 is the last value in $ds.
I'm creating a drop down menu so that when a user clicks on the drop down arrow and then hovers over one of the options, a bubble comes up and does a validation. The thing is that everything works fine in Firefox, but not in IE or Chrome. The problem is that the .mouseover() function doesn't work on the <option> tags in IE and Chrome, but it works fine in Firefox because apparently FF is the only browser that supports it.
View 3 Replies View RelatedI'm trying to change a word in an animated collapsible div script from Dynamic Drive. When clicking "Hide" I want the word to change to "Show". I have part of the script, but it's not working correctly - it just removes "Hide" when clicking on it. See the example here.
The code so far is this:animatedcollapse.ontoggle=function($, divobj, state){ //fires each time a DIV is expanded/contracted
//$: Access to jQuery
//divobj: DOM reference to DIV being expanded/ collapsed. Use "divobj.id" to get its ID
//state: "block" or "none", depending on state
if ($('#'+divobj.id+'-toggle').length==1){ //if toggle link has id 'divid-toggle' defined
if (state=="block")
$('#'+divobj.id+'-toggle').prepend('<span class="prefix">Hide </span>')
else
$('#'+divobj.id+'-toggle').find('span.prefix').remove()
}}
I'm totally new to jQuery.
My plan is to create a JavaScript class, with some functions and variables, and one of the functions is called when a user clicks on a certain element. However, I need to find out the ID of the element that was clicked (in the example, that of the <p>) for further processing. It looks basically like the following:
[Code]...
The result was very crazy, because console.log(this) gave me the node as result, and console.log($(this)) did the same only as jQuery node, but trying to find out the attribute via jQuery gave undefined as result. I haven't checked if this.id would work (should probably), but I'd prefer to keep the whole script in jQuery, if possible. I suspect it may be an overusage of the 'this' keyword, but if so, what's the proper way to do it?
I have problem with this code:
jQuery('.container').on('click', '.item a', function(event){
showContent(jQuery(this).attr('href'), event);

i'm looking for the best way to use global properties that defined at class level insid event handler functions.
for example :
function MyClass() {
this.v1 = "hello";
this.v2 = {name: 'joe', age:'30'};
this.link1 = $("<a/>", {id: "link1"});
[Code].....
actually, in link1Handler 'this' returns to link1 not to main class. so how to get class properties or functions inside the private functions of the same class?
I haven't come across an exampe that would enable me to pass data to my event handler.For example, if I click a button I want it to pass the value of an adjacent text input to my handler.

I pulled out an old javascript object I created a while back a few days ago and I've been developing in Firefox ever since. Then I decided to test how it worked in other browsers and.....it works in none of them! Not chrome, not IE(7/8), not opera, and not safari.
It's built like this:
Code:
function myCalendar() {
//constructor function
}
myDiv.prototype.newMethod = function() {
[Code].....
It's really as simple as that....what's on the go? Do any JS experts out there know anything about this?
I am have an MVC app that generates a list of rows, of which one of the columns is a button. Here is the rendered HTML for the buttons:
<input
id
="btnUpdate21"
type
="submit"
value
="Approve"
synchId
="21"
/>
<input
id
="btnUpdate22"
type
="submit"
value
="Approve"
synchId
="22"
/> .....
Following is my selector that I use to bind the buttons to my click event:
<script
type
="text/javascript"
charset
="utf-8"
>
$(document).ready(function
() {
$('input[id^="btnUpdate"]'
).click(promptForSynchDate);
});
I have been trying to access the button Id, though what I really need is the attribute synchId, to use inside of a modal. I have so far been unable to access either one of them. My modal works fine. But the value of either attribute is always "undefined".
Here is my click event handler: (I stuck the alert in there just for debug purposes)
function promptForSynchDate() {
$(document).ready(
function () {
var test1 = $(this).attr('id');
alert(
'test1 is : ' + test1);
$(
'#approve-synch').dialog({ .....
