Onclick Handler Firing Multiple Times When It Shouldn't?

Jul 23, 2005

I have a web page that tracks clicks on certain hyperlinks. I am using
attachEvent() to attach to the document onClick handler, for IE browsers.
It works fine, except that for about 1 out of every 6 clicks, I get 2 to 4
click events for a single click. I know this because each time the
hyperlink is clicked, I write a record to a MySQL database. I write the
record to the database by setting the SRC property of an IFRAME on the page,
to a tracking script.

If I look at the database, for 1 out of every 6 clicks, I see 2 to 4 records
for the same click event (occassionally as many as 6 records). They are at
least 1 second and at most 7 seconds apart from each other.

Onclick Not Firing After Onchange?

Jan 22, 2010

I have an input text with an onchange event that calls a function in which an alert box displays. I also have a button whose onclick calls a different function. If the user makes a change in the input text and immediately clicks the button, the onchange event fires, displaying the alert box, but the code in the function for the onclick of the button doesn't execute. I've read that this has something to do with event bubbling, but I haven't seen any solutions.

2 JS Functions Not Firing Correctly (one After The Other) Onclick

Sep 12, 2011

The context: I am trying to fire a Google Analytics Tracking Code, and a Website Optimiser Conversion Script on an Onclick, one after another, before following an external link. It's on an image button. It must work for JS disabled. The Problem: The first one was that the newest browsers were executing the external link before the tags were firing. I added return false; to stop this which it did. This however ignited an old problem I had - being the two scripts just would not fire one after another. The Code:

Onclick Handler In 'for' Loop ?

Mar 30, 2010

I'm finishing up the front-end of an events management application, but I'm running into a problem with my javascript.

Here's the scenario: I have the php application returning all event details into a JSON object.

The object structure looks like this:

Code:

Each event title listing on the calendar grid is assigned "#" plus the event's ID for it's link, just for testing purposes--no problems.

Eventually, I want the user to get a yui container (modal) with the event details, but when I add the onclick handler to the links, the id that gets passed for each of the links is the same, 60 (which is the ID of the last iteration in the loop).

Here is my code:

Code:

I've tried using the var keyword to localize the id, but that produced the same problem.

Dynamically Created Control's Onclick Not Firing?

Mar 24, 2010

So i have a javascript function which clones a Node on my page. That part works fine, as does the renaming of all the controls. The part that i do not understand, and cannot get to work is that several of the controls have an onclick event. On the dynamically created controls this onclick does not fire. Does anyone know why this would be, or possibly how to get around it?

Onclick Event Handler Not Running When Run Twice

Mar 25, 2011

i have registered a validation function as the onclick event handler. It runs for the first time but does not run when i click on the button the second time. ( this is because i have put an aert box in the validation function and it does not show up when i click on the submit button for the second time)

here is the code

Code:

<input type="submit" value="Submit" action="submit.php " onClick="return validate('add_item_form');">

Code:

function validate(form_name){
validate=1;
string="";

[Code]....

when i leave all the fields of the form blank then the error message is displayed. But when i click on the submit button again then the validation function does not run.

DOM: How To Associate A Value From A Database With An Onclick Handler?

Jun 21, 2006

I am trying to use DOM to create a UI for editing info pulled from a database. The info pulled are the locations of a given company. So, company A might have 2 locations (address, city, zip), and this is the info I want to present.

The way I have it now I use dom to parse the returned XML file and display the location info for each location on a seperate line. At the end of each line I want a button that the user can click which will then replace the current line (just text) with 3 input boxes populated with the values for address, city, zip.

Another button (UPDATE) will then be used to call a function which will update the db with the new location information. This is all no problem, but the part I cannot fathom is how do I associate the "location id" (from the database) with the UPDATE button on a given line, so that when the UPDATE button is clicked the function it activates will know which location (ie row) in the db to update. Code:

Add OnClick Event Handler To Each Banner

Feb 11, 2009

I've successfully used the Random-Order javascript on my site for years to shuffle around a number of banners on my main page.I now want to add an onClick event handler to each banner so that I can use Google Analytics to track those exit links, but I can't get the script to work when adding the onClick; the banners just don't show up on the webpage then. I'm pretty sure that some coding needs to happen in the function area below the content section, that just putting the onClick in each item won't do it, but I don't write this stuff, so I have no clue what to do to make it work right. Here's the script WITH the onClick code I would like to add in red. If you were to remove everything in red, the remaining code would be exactly as it currently appears on my site and works properly.

Adding An Onclick Event Handler In The <option> Tag

Feb 9, 2009

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?

Dynamically Setting Query String With <select> Onclick() Handler

Jul 23, 2005

I need to pass the selected option of a <select> tag into a query
string, so that the page is reloaded with the selected option already
chosen. This will occur with the onclick() event hander, and the query
string will be processed using a server-side technology. I'm just not
sure how to word the "onclick" handler. Here's what I have:

<select id="StartMonth" name="StartMonth" onchange="location.href =
'thispage.cfm?StartMonth=_______'">

What is the correct wording to set the underlined portion to whatever
was selected? I know it has to be done with JavaScript, since the
decision is made on the client-side.

JQuery :: Accessing Button Attributes OnClick Event Handler

Nov 30, 2011

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({ .....

Set An Onclick Event Handler To Call A Function Which Requires A Parameter?

Jun 11, 2011

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.

Display One Div Multiple Times

Apr 15, 2009

I'm currently working on a browser based 2d multiplayer rpg using PHP and ajax. As the number of beta testers has increased, I have found that there is a significant amount of lag involved in changing maps (maps are 480x480px ea consisting of multiple images. What I would *like* to do, ideally, is only load each image once. So the first time I encounter "grass1.png", for example, it is loaded into div id "grass1", and never needs to be loaded again. My question is this, is it possible, to do the above, and then call div id "grass1" for each instance of the image?

This way, I could store all images encountered thus far. When the player left a map, all images would be positioned off-screen, and moved into the field of view as needed. I am already doing this, but there is a div for each unique object. (meaning there could be 10+ divs for the same image, for just one single map!). This would be much more efficient if I were able to call and store just one div per image, and just display it multiple times in multiple places.

Run A Function Multiple Times?

May 20, 2011

I made a sort of typewriter script that shows every next character of a text in a particular DIV, each milisecond. (testing in IE, not tested in other browsers yet)

Now, after the function has run, I cannot run it again. It stops all completely.
I have put some variable in it to see it's running or not. But that doesn't help it anyway.

Has this something to do with event bubbling or something else?

Code JavaScript:
<html>
<head>
<meta http-equiv="Content-type" content="text/html;charset=UTF-8">
<title>Test</title>

Stop Multiple Onclicks From Firing On Layered Divs?

Jun 6, 2010

I'm writing a GUI css/html editor in JavaScript which is a litte ambitious considering I just started with js like a month ago. Here's my first hurdle:

Users can add divs simply by clicking on the div or element in which they want the new div to reside. The creation of a new div is in the onclick event. However, when I click on a div, I'm getting an onclick events from it and all the divs positions below it, so it's creating multiple new divs and all I want is one!

Is there any way to make the onclick even fire for just the top layer div? Maybe using the z-index or something?

Possible To Call Function Multiple Times

Apr 13, 2010

I'm currently working on my first ever javascript and have run into an issue.
Source:
Code:
<script language="JavaScript">
img_width = 0;
img_height = 10;
timer = null;

function imageGrow(bar_len) {
growImg = document.getElementById('imageResize').style
growImg.width= img_width;
if(img_width != bar_len) {
img_width += 10;
timer = setTimeout('imageGrow()', 20);
} else {
clearTimeout('timer');
}}
</script>

<img onLoad="imageGrow(100);" src="img/graph.jpg" border="0" width="1" height="10" id="imageResize" align="center"><br />
<img onLoad="imageGrow(50);" src="img/graph.jpg" border="0" width="1" height="10" id="imageResize" align="center"><br />

I have 2 issues. First, the second image does not call the javascript and I assume this is because both images have the same ID? Can I associate code to 2 elements? Is it even possible to call the function multiple times in the way I'm trying to? Second, as the script is written above, the image never stops growing even when it reaches '100' as specified in the script. If I change 'if(img_width != bar_len)' to if(img_width != 100) it does stop growning when it reaches 100. I am unsure why, as bar_len = 100 when I call the function! I don't know if it makes any difference, but the HTML in my final code will be dynamically generated with ASP.

JQuery :: .live() Fires Multiple Times?

Oct 18, 2011

I have a problem when I use the .live() function that I can't figure out. It's something I've run across several times and it keeps confusing me.

My jQuery:

jQuery('#content div.portfolio').live({
mouseover: function(){
jQuery(this).find('img').fadeOut();

[code]....

My problem is: when the mouse enters and leaves the image the image fades in and out for up to four times. The first mouseenter is just fadeout, fadein, fadeout. why is the event being triggered multiple times and more importantly what can I do to prevent this behavior?
