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 the following code:
<script language="JavaScript">
function func1() {
alert("func1 invoked");
}
function func2() {
alert("func2 invoked");
}
function changeFunction() {
var img = document.getElementById('img');
if (window.addEventListener) { // Mozilla, Netscape, Firefox
img.addEventListener('click', func2, false);
}
else {// IE
img.attachEvent('onClick', func2);
}
}
</script>
<img id="img" src="test.jpg" width="10" height="10" onClick="func1();"></img>
when the image is clicked with the mouse, function func1 is invoked as expected. When I call function changeFunction, I want to change the code that is invoked when the image is clicked from func1 to func2. Instead, both are invoked because addEventListener and attachEvent add an additional handler instead of setting one.
I am looking for a way to change the handler from one function to another. Can anyone think of a solution probably using removeEventListener?
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) {

I am trying to stop a preloaded images used in a rollover. The images are linked to a tab navigation system, that open on the same page.

// enumeration of the "active" images

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:

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.
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 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 got this problem with live() event.I have used it as follows.
$(".addressDiv span").live("mouseover", function(){
//clickable function here......
------------------------
});
I have used the live() event to trigger the function on mouseover in the dynamically added elements. But the problem i got is that once the live event is called it takes the class of the element and stores. And when the class of that particular element is changed dynamically the live() event does not detect the new classed added dynamically, instead it takes the former class. Live() event does not update the class.
currently on our site we have and expanding <div> that responds to both the onmouseover and onmouseout events. It works wonderfully.
The UX people now would like the expanding <div> to open with the onclick event and then as soon as the mouse leaves the expanded div, it would close. I have tried using the onmouseout event in conjunction the onclick event but it does not work (the div persists).
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?
I have a page with 3 divisions overlaying each other. I dynamically
change the visibility to switch between them. On the Mac version of IE
5.1 I am not able to activate the scroll bars after making a division
visible. Only the originally displayed division works. I am able to
click on the data (option select lists) in all of the divisions. There
is no problem when I use Netscape.
I would like to dynamically change the z-index to see if that would
help. Can someone tell me how?
I have a piece of javascript I need to modify. Right now it changes a stylesheet in the document between style.css and no_indent.css. These
are in the head of my document:
<link rel=stylesheet href=/style.css>
<link rel=stylesheet href=/no_indent.css>
<link rel=stylesheet href=/style.css>
What the code below does is toggle between the two depending on what link is clicked. Here are the links:
<a href=javascript:changeSheets(1)>Threaded</a>
<a href=javascript:changeSheets(2)>Flat</a>
What I want to do is have one link that will toggle between the two
stylesheets. So the page loads style.css initially. If the link is
clicked once it changes to no_indent.css. If it's clicked again it
changes back to style.css, and so on.
Can anyone let me know how to do this?
code:
----------------------------------
function changeSheets(whichSheet){
whichSheet=whichSheet-1;
if(document.styleSheets){
var c=document.styleSheets.length;
for(var i=0;i<c;i++){
if(i!=whichSheet){
document.styleSheets[i].disabled=true;
}else{
document.styleSheets[i].disabled=false;
}
}
}
}
Is there a way to change the contents of a div block dynamically? Or should I use iframe instead?
View 9 Replies View RelatedI'm having a problem dynamically changing the color of a table background.
I'm not sure exactly how to word this, but I'll give an example.
I have a function called greentored(propname)
i want to be able to change the following to a different color:
document.all.propname.style.visibility
but substitute the propname with the variable that I'm sending over.
Here is what I had written before but it did not work, it should be easy to
understand what i'm trying to do:
function greentored(propname) {
changecolor = "document.all." + propname + ".style.background";
changecolor = "green";
}
I understand why this doesn't work because all i'm doing is reasigning
"changecolor" to equal green, rather then setting the property of the first
instance of "changecolor" to green.
I have a template that will have tons of different background options. I want people looking at the demo to be able to test out each one without having to reload the page.

I am building a schedule web page and before I just had it use plain static HTML and CSS to control the styling. I wrote some javascript that goes through the table's rows, then cells (double for loop), and if the cells innerHTML == "" then the style class is changed. I do have some working code, however it only works in IE. Here's a copy of the script:
<script type="text/javascript">
for (var i = 0; i < document.getElementById('table').rows.length; i ++)
for (var j = 0; j < document.getElementById('table').rows(i).cells.length; j ++)

Instead of implenting a prefabricated calender on my site, I tried a different route. I built a simple form where the user picks time and date. Now, what I need to do is to secure a dynamic changing of the <select> tag carrying the values for days in the month, based on what information the user has put into the <select> tag carrying the values for the month. This should be logical, as it should not be possible to choose ie. the 31st of June, as there's no such date. I hope you understand what I need.

I have a drop down box on a site, and when an option is selected, I need the value of a text box to change.
My form has the following in it:
<select name="event">
<option value="" onclick="updateprice(0)">Please Select..</option>
<option value="3" onclick="updateprice(25)">Monday 16th February 2004 (£25 per ticket)</option>
<option value="2" onclick="updateprice(20)">Saturday 28th February 2004 (£20 per ticket)</option>
</select>
and I have this javascript function:
function updateprice(theamount) {
document.nonmember.adminprice.value = theamount
}
the form is called 'nonmember' and the text box i need to change is called 'adminprice'.
Everything works fine in mozilla, but in IE nothing happens when I select an item from the drop down list (not even a javascript error)
I have a flash header on my website with 5 menu items (home, register, about us, etc)
myheader.swf?button=1 "Home" is focused
myheader.swf?button=2 "register" is focused
etc etc
When you click on a menu item it becomes the focused menu item (or "button") and the flash fires off a javascript event which handles the AJAX.Using the browser's back/forward buttons, the flash header's focused item does not change.
I can capture the history change, but how can I change the " .swf?button=x " using javascript.
PS: the flash header is a big file and I do not want to reload it every single time to update the var
