Cannot Dynamically Set OnClick ?
May 23, 2009
I'm having a problem with adding onClick events to <a> tags. The attribute is never added at all, but no errors are shown in the JavaScript console. I'm using Firefox 3.0.10.
Here's my code:
I made sure that the conditional statement was working correctly by adding an alert to the onClick portion, and the alerts worked fine. However, the onClick event is never added, not on Firefox or IE7.
It also works fine if I change each <a> tag's href to javascript: getPage(); , but I don't want to change what shows in the status bar.

so i have two functions, expand and colllapse. i want the buttons to start on collapse, and when pushed, change to expand. for instance:
<img id=img1 src=minus.png
so now in the collapse function, i want something like:
var imgID;
imgID = document.getElementById("img"+what);
imgID.src = "plus.png";
imgID.
changing the src works, but changing the onClick does not.
I've found some ways to change the onClick to a function Code:

I have a form in which i have multiple textboxes and radio buttons.
The form is dynamic in that if certain selections are made fields appear/disappear.
This is controlled client side by javascript. The whole form is set up correctly.
However these forms then read off an oracle database. This populates the form. (in effect selecting certain options)
i would like to be able to recurse through the document, selecting which elements are checked and then run the associated onclick method.
So far i have this whacky non-functioning code: (it finds the correct elements, but how do i run the onclick method?)
function load() {
var tags = document.getElementsByTagName("input")
for (var i=0;i<tags.length;i++) {
if (tags(i).type=="radio" && tags(i).checked==true) {
[Code]....

I have a function whose parameter is a reference the element that called it:
function someFunction(el)
{
...
}
The function is assigned to the onclick event of some elements in the
HTML source:
<input ... onclick="someFunction(this);" ...>
and dynamically to others:
elRef.onclick = someFunction;
When someFunction() is called from the statically-assigned onclick, el
is a reference to the element. But when it has been added dynamically,
el will be either undefined (IE) or 'event' (Mozilla et al).
To assign the right value to el, I can test if el exists and if it does,
whether its constructor is some type of HTML element or 'Event'. But IE
doesn't support the constructor property for elements (or have I just
not found it yet?) nor does it understand 'Event' the way Mozilla does. Code:

The following is a very simple example of what I want to do take an
elements oncontextmenu and changing it dynamically onclick of that
same element. The code below will fail unless you change the line
document.getElementById('div1').setAttribute('onco ntextmenu',
someText);
to
document.getElementById('div1').setAttribute('onco ntextmenu',
function(){alert('World World');return false;});

I have a small script which dynamically creates select tags (they are placed within divs). Each select has a + and - sign next to it, and if you click the + it adds another select below that one, or if you click the -, it removes that current select.
I've made it so that if there is only one select, it can't be removed. So i made it like this, when i create a select, the remove button is inactive. When i click to add another select button, it becomes active. The problem is that the onclick event is not working with any browser except Opera. This is the code:

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?

I'm a JavaScript noob, and I'm playing with it. I have some code which created a div inside another div by using the innerHTML of the outer div. That had an onclick event which worked fine. Now I'm trying to create the div as an object, so I'm doing something like this:
Code JavaScript:
var obj = document.createElement('div');
obj.id = "object";
obj.onClick = function() {alert("Clicked");};
obj.innerHTML = "something"; // an img tag in the actual code
document.getElementById('objects').appendChild(obj);
The new div is shown, but clicking on it does nothing. (I originally had another function, but changed to the alert for testing.)

I have a function that dynamically creates a new div, part of the function looks like:
root = document.getElementById('rootbox2');
var oDiv=root.appendChild(document.createElement("div"));
with(oDiv){
id=ji;
className="workshopRow";
setAttribute("attending","");
setAttribute("attending_count","0");
}
var oText = oDiv.appendChild (document.createTextNode(""));
var oDiv1=oDiv.appendChild(document.createElement("div"));
with(oDiv1){
className="workshopName";
}
var oText = oDiv1.appendChild (document.createTextNode(""));
var oSelect=oDiv1.appendChild(document.createElement("select"));
with(oSelect){
name="select_"+ji;
id="select_"+ji;
className="workshop";
onchange="calc_subtotal("+ji+")";
}
var oText = oSelect.appendChild (document.createTextNode(""));
var oOption=oSelect.appendChild(document.createElement("option"));
with(oOption){
value="12";
setAttribute("price",10);
}
What I am looking to do is add an onchange event to the select element, not sure if i have programmed it correctly but it does not seem to work.

Below is the code.
My function:
function swap_content(id1,id2)
{
var tmp = document.getElementById(id1).name;
var theval = document.getElementsByName('primary_propertyp_id')[0].value;
document.getElementById(id1).name =
[Code]...
This is running through a PHP loop so it's making multiple divs and links for the secondaries. I am wanting to be able to swap out any of them to make them 'primary' this works for the first click, but after the first click it makes every div id and input name the same as the first that was clicked. It's also not working AT all if i click on the bottom link first, then a link above it. Top-down works, bottom-up doesn't..

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.

I have some JQuery that makes an Ajax call and then adds some rows to an existing table.
function
LoadDestinationTable() {
$("#destinationTable tr:gt(0)"[code]...
The problem is that the only place where the click event fires is on the rows that were added when the page was 1st rendered – the th, for example.I also tried adding an onclick event handler to the input button’s creation – that also does not fire.

I am using the Collapsible Checkbox Tree jquery Plugin.For that I have inserted this linein the javascrypt code:
When I make a list in the HTML code using the <ul id="example"> works perfectly.
But when I tried to make the list dynamically calling a JSON file, does not works fine.
If I insert theready(fn) mentioned above inside the javascrypt function that create dynamically the element<ul >as is shown next:
Improves a little bit, but still does not work fine. Specifically does not show the plus and minus sign, then I can not open or collapse it.
I tried also with thecheckboxtree pluginand I encountered the same problem.

At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code:
var tbody = document.getElementById('tableItems');
var row = document.createElement("tr");
var remainder = tbody.rows.length % 2;
if(remainder) {
row.setAttribute("class", "rowLightGreen");
}
var td1 = document.createElement("td");
td1.appendChild(document.createTextNode(qty));
td1.setAttribute("class","qty");
row.appendChild(td1);
tbody.appendChild(row);
One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?

I want to make it so that when I click on something, it changes what document.onclick does.
This is a simplified version of what I'm trying to do:
Code:
<div id="clickme" onclick="document.onclick = function(){ alert ('This should not be alerted on the first click'); }">Click here</div>
However, as you'll notice, the alert box shows up on the first click as well. The only way I have been able to get around this behaviour is to have the first onclick execute a timer that will then set the document.onclick after 1ms, however this seems very messy to me.

I have the following sample code and when I click the a href link it pops up both windows.
HTML4Strict Code:
<tr false;" style="cursor:pointer"> <td>Some data</td> <td>More date</td> <td><a href="thatlink.html" false;">Details</a></td></tr>
In other words - linking the link that should open up 'thatlink.html' opens up that window first followed by the 'thislink.html' window in the table row onclick call.

I have a few radio boxes where a user can choose different options and
I want to show an explanation of each option after it's clicked.
Here's what I have:
<script type="text/JavaScript">
function toggle(o){
o.className = ( o.className == "show" ) ? "hide" : "show";
}
'function describetype(){
' if (window.event.srcElement.value == "starter")
typedesc.innerHTML="A Starter request is for a new employee who's
never worked for cadbury or the Bottling Group before.";
' if (window.event.srcElement.value == "leaver")
typedesc.innerHTML="A Leaver request is for an existing employee who's
permanently leaving the company.";
'}
'function starter(){
'typedesc.innerHTML="A Starter request is for a new employee who's
never worked for cadbury or the Bottling Group before.";
'}
'function leaver(){
'typedesc.innerHTML="A Leaver request is for an existing employee
who's permanently leaving the company.";
'}
function describetype(o){
if (o == "starter"){
typedesc.innerHTML="Starters are...etc.";
}
if (o == "leaver"){
typedesc.innerHTML="Leavers are...etc.";
}
}
</script>
The first "toggle" function works fine but the "describetype" won't
work. Here's the HTML:
....
<td class="layout bold">
<input type="radio" name="reqtype" value="starter"
checked="checked" onclick="describetype(starter)"Starter<br>
<input type="radio" name="reqtype" value="leaver"
onclick="describetype(leaver)"Leaver<br />
</td>
<td class="layout bold">
<input type="radio" name="reqtype" value="mover"Mover<br />
<input type="radio" name="reqtype" value="adhoc"Ad Hoc
</td>
....
The error keeps saying that "starter" or "leaver" is undefined. I'm
not much of a javascript guy (mostly the cut and paste variety myself)
but everything I've seen says this should work. No?

Currently I am doing this:
What I'm actually doing is inserting the current time into an existing DIV and updating it every second. THAT all works.
What I want to do is also set an event for that div.... something like this:
Of course, the above doesn't work... and I'm not even sure what to ask for doing a Google search... because I get no hits (or maybe it's not possible).
I really don't want to edit the code itself (where that div is) because it's part of another app that may change as they update it and I don't want to have to re-patch every new release.

I thought about following code snippet code...
Has anyone an idea, if my thoughts on that are correct oder if this behaviour could be a problem?
And is there probably a better way to combine functions, so that all functions would be in one column?
