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:
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 try to find working example, but no luck.I need this very simply javascript to onClick change value and second click change value back and third click change value again back and so on..
View 7 Replies View RelatedI'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.
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 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:

View 2 Replies View RelatedSo 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.

View 1 Replies View RelatedI have a bunch of input rows, each with id in the form of something like.. item:characteristics:age or item:setting:type1:blah. It's kind of like going down folders to get to the item I want. So as you can see in the code, I am splitting each id and trying to rebuild it in the form item[characteristics][age] then set it to the value of the input field. This is modifying the properties of the item. We already have the item object passed into my code and i'm simply modifying the properties to the new values from the user's input.
Does anyone know how I can do this without eval? I'm mainly using it because the variable name can't be hard coded, it is dynamic.
Here's the code I have so far.

[Code]...
am at the very beginning of Javascript. This is the first website I tried to include Javascript, so don't be too mean
What I want to do is to change a CSS property dynamically. It'll be best if I show you what I did:
<script language="javascript">
function ChangeHeight()
{
var browser = navigator.appName;
[Code].....
Why I want do change this? Well... Different people have different resolutions and I want that my website fits perfectly into the browser.
alert(document.getElementById('content').style.height); This shows just an empty MessageBox with nothing in it.
Something I would like to do is change the value of a label. Let's say I have a textbox and onchange, I want to change the value of that label (say adding numbers together or string concatenation).
This works fine if I use another textbox instead of a label, but I want to show Text rather than an input type. Is this possible? I avoid JS at all costs b/c I tend to suck with client-side programming.

still beating my head for a popup window anyway I can get it. With JavaScript I can change the content within tag "bodies" but is it possible to change the actual tag itself.
Code:
<form id="loginForm" name="login" action="" method="post" onSubmit="timerWindow($username)">
<input type="text" name="username" value="" onBlur="doUsername();">
I'm using onBlur on the username field so as soon as the event happens I can do the JavaScript call. What I want to do is have the username (that was just entered) passed to the timerWindow function. I think it is getting close to being solved.

Is it possible to use Javascript to dynamically change the PHP file used for an include?
For example, if I have a php doc like
I can get Javascript to remove the included stuff, but I can't figure out how to change the <?php include('onefile.php'); ?> into <?php include('otherfile.php'); ?>.
