I did some searching around, but didn't see this addressed directly. Here is an example of when dot notation fails in Firefox, and when SetAttribute doesn't fail: Code:
View 4 RepliesI've been working on this for about four hours (two today, two yesterday) and keep hitting the brick wall. I'm trying to create a function that will add an attribute to specified tags. As the title says, it works great in FF and not at all in IE7. Probably the first question you'll ask after you see my code is "why?" Well, I've got a form with over 100 form fields in it, and if I can avoid manually adding an attribute to all of them, I'll take the JS route.
[Code]...
I am having a terrible time getting the following code to work:
var foo = {
bar : "bar",
fooTwo : {
bar : foo.bar
}}
When this code runs, I am told that foo.bar does not exist in line 4. Why am
I getting this error?
I have difficulty understanding how square brackets work in JavaScript and this is causing me difficulty retrieving the values of the options of my Select controls.
My form contains many select boxes. Their names are stored in variables(in this case concat is the select control name) and I have no trouble accessing methods for the select object ie:
document.Allan.elements[concat].selectedIndex;
I would like to get the value of the selectedIndex but I am having difficulty because I don't know the right syntax. I'm looking for a statement like the one that follows but uses variables
document.form.theDay.options[2].text
Could some one help me use the right syntax?
Is it possible to have something like the following so that 'three'
can access 'one':
var x = {
one: 1,
two: { three:this.one } // Or parent.one ?
}
If not (which I have nearly come to a conclusion on) what is the next
best way to accomplish this?
I've started learning writing javascript objects with literal notation...
Instead of the usual syntax...
The problem is that it's hard for me to adapt procedures which I'm used to within the normal syntax for the literal notation. E.g:
Is this variable global or local? If it's local, how do I declare a variable globally? I also wonder if it is possible to bind events to objects from within the object? And if I'm correct - jQuery is coded this way, but how can they then make use of their selector:
When it is an object defined with literal notation that doesn't have a constructor?
i want the following var i="name";console.log({i:'value'}); o be equivalent to (as an end result)
var i='name'; var t={}; t[i]='value';console.log(t); is that possible?or must i use the second method?
I'm declaring a class in OLN:
Code:
The problem is that in IE, when I call myfunc() it complains with the error: Class is undefined
I'm not sure what I'm doing wrong. Class is declared in as much global scope as possible, and that shouldn't even matter in JS.
I'm trying to put a function in a object created using JSON notation. The syntax looks like this...
Code:
historySet = { ajaxRunFunction: "updatePageCopy('" + pageID + "','','" + pageName + "')"};
It works fine in FF, but in IE it calls the function updatePageCopy when it creates the object history set. I don't want to call the function when the object is created.
this script updates an image on a page and resets the class name of a link. Works fine in Mozilla browser. However, the setAttribute method in the second function doesn't work in IE. Is there a known bug connected with this?
Any ideas?
var view;
//update image
function getView(view)
{
var source = view.getAttribute("href");
var imgsrc = document.getElementById("view");
imgsrc.setAttribute("src", source);
setClass(view);
}
// update class names of links
function setClass(view)
{
var arLinks = document.getElementsByTagName("a");
var ct = (arLinks.length-1);
for (var i=0; i<ct; i++)
{
arLinks[i].setAttribute("class", "inactive");
}
view.setAttribute("class", "active");
}
I am struggling to write an meta element in JS. The meta element in question
is the refresh element.
This is the code I am using
//----------------
function setMetaContent(metaTag, metaName, value) {
//----------------
var metas = document.getElementsByTagName('meta');
if (debug) alert('[setMetaContent] metaTag='+metaTag+' metaName=
'+metaName+' value '+value);
for (var i=0; i<metas.length; i++) {
if (metas[i].getAttribute(metaTag)==metaName)
break;
}
if (debug) alert('[setMetaContent] i='+i+' value '+value);
metas[i].setAttribute('content',value);
}
and I call it with:
How do I use a variable in setAttribute ?
View 1 Replies View RelatedI'm in the process of migrating a script to use DOM core methods but I've hit a roadblock in the aforementioned browser. The following code snippet illustrates what I'm basically trying to do, it really is incredibly basic!
var newimg = document.createElement('img');
newimg.setAttribute('id', 'placeholder');
newimg.setAttribute('src', 'images/large/courtyard.jpg');
I'm then positioning the element on the page using appendChild(). Everything works perfectly on Firefox 1, IE5+, Opera 8, Konqueror 3.3.1 (Linux) but not in Opera 7.54. I suspect the element is being created as associated styling on #placeholder is being applied (just some padding and borders) but the image itself is not being displayed. I assume therefore that the problems lies with setAttribute()?
This seems like the sort of problem that others would have encountered, but I haven't been able to find mention of it anywhere.
this works perfectly in firefox - but in internet explorer it just creates the first lable and the input field, although it creates the input field as a regular text field instead of for files. the caption label and text field aren't created at all. any ideas? Code:
View 7 Replies View RelatedI am using the following code to create an 'a' element with 'texto' to add the onclick property to an object:
var vinculo = xCreateElement('a');
var nodoTexto = document.createTextNode('texto');
xAppendChild(vinculo, nodoTexto);
xAppendChild(celda2, vinculo);
vinculo.setAttribute('onclick', 'buscarSolucion(1,1,1)');
'celda2' is a table cell. This works with FF but not with IE. I solved this using a comment from here for the 'name' attribute, like this:
...
vinculo = xCreateElement('<a onClick="' + onClick + '">');
...
But I would like to put it in a function to make it general for any element that has the 'onclick' property. Is there any other way to set the 'onclick' attribute & to be understand by IE & FF?
NOTE: I also found that I can not set 'colspan', I have to set colSpan. Also, I can not set 'class' I have to use the canonical method with 'object.className=...'
I know there is a problem with IE (I wont bother inserting a witty comment here) on handling:
setAttribute('onclick','doStuff');
I have found
yourAnchor.onclick = function() {
// do what you want in here.
}
this works, but I the script I am working on is going through every DIV with a certain class and adding links to the div, I want the button to change something within the div where it is located so I need to pass the id of the parent div. I thought perhaps there was someway to find the id of the button pressed?
I'm trying to get a return of

Just after upgrading from v1.4.3 to v1.4.4 I started receiving this javascript error on the console, but apart from the update, I didn't do any code modifications. If I follow the console link, it takes me to this point in the source:

Im writing a piece of javascript that dynamically adds a link to a page, this is the code i'm using
var newP;
newP = document.createElement("a");
newP.innerHTML = "Click here";[code].........
However, it wont work?!?! the link appears in the right place on the page when i remove the line newP.setAttribute("href","http:[url]......);and if i view the source the link is <a>Click here</a> (without any href) so there's got to be something wrong with that line but i don't know what it is.I'm using firefox.
It works OK in IE and Moz, but in Opera the change of the attribute's value works on once, first time. No error. That confuses me. Why works only once? Any ideas? Code:
View 16 Replies View RelatedI have multiple attributes (class, id and title) that is needed to insert into a div together. All I know how to use setAttribute for single attribute. So the question is there an "array" setAttribute method to insert all attributes together into an element OR is there a "after" or "before" setAttribute method I can use to insert an attribute after or before other attribute?
View 2 Replies View RelatedI want to implement:
<a href=123 onclick="javascript:return false">123</a>
in DOM,
I have:
var link = document.createElement('a');
link.setAttribute('href', 123);
link.setAttribute('onclick', 'function() { return false; }');
but it doesn't work. The reason I want a href and onclick = false is because I want to drag and drop the 123.
I need setAttribute "src" from main windows to pop-up window (Iframe in it) and also i need to prepload all src files ONCE, so if user ever click to open pop-up and do it againt, its no need to loading againt, can anybody help with the script ... ? Or maybe can sugest me with better method to have same result.
View 3 Replies View RelatedI have the following code:
A = {
"value": "a",

B = A ;
B.value = "b";
alert (A.value); // => b
I expected A.value to be "a". how can I change values of a new object, without changing the parent-object?
I have a line which looks like this in PHP:
Code:
<input id="btnCancel$folder_id" type="button" value="Cancel" onclick="swfu.$folder_id.cancelQueue();" disabled="disabled" />
and of course when output looks like this:
Code:
<input id="btnCancel111" type="button" value="Cancel" onclick="swfu.111.cancelQueue();" disabled="disabled" />
It seems that the .111. throws an expected ";" error. swfu.cancelQueue(); by itself does not.
These objects are being defined in a function which takes in the folder ID as a variable, and then builds using this line:
Code:
swfu[folderId] = new SWFUpload(settings);
I am trying to setup a form with radio buttons. Each radio button has an OnClick event. When a radiobutton is clicked the current set of radio buttons will be replaced with a new set using document.createElement("input"). Each new radio button needs the same onclick event addedas in the initial set of radio buttons. I first tried:
element.setAttribute('onclick', MyFunction(value));
This, however, will somehow automatically trigger the onclick event! I searched on the internet and found this as the solution:
var new_onclick = function() { alert("this works!"); };
element.setAttribute('onclick', new_onclick);
This will give a "Object" is undefined error!
