Changing InnerHTML Of DIV From Within IFrame In Firefox
Nov 9, 2010
I created a page that has an iframe on it. Within this iframe I call an asp page. The asp page is supposed to do some work and then update the innerHTML of a <div> object on the parent page to indicate that processing of the page in the iframe is complete. The code works in IE but not FireFox. I am wondering what is the best way to make the script work for both browsers?
Sub page JavaScript:
updateParent(){
parent.document.getElementById("num2").innerHTML = '<center><strong>Processing complete.</strong></center>';
}
Parent page:
<div id="num2"></div>

Ive got a small image of a power button and when pressed the inner section on the button changes to yellow, but when its pressed down Im also trying to get part of my H1 (main header logo title) to change to yellow.
Ive created a span with an id surrounding the letters of the H1 that I want to change, the id being : "power";
The javascript that I have come up with so far and works is as follows:
<img id="poweron" src="http://www.sitepoint.com/forums/images/power.png" alt="Power on button" onmousedown="this.src='images/poweron.png';" onmouseup="this.src='images/power.png';"/>
I understand Im not really supposed to be using inline JS, and I know Ive got to create a function for the onmousedown event to trigger changing the H1 text, so am I under the right impression that the JS so far written is redundant and will have to be re-written so thats contained within a script placed just before the closing </body> and an external script for invoking the main function ?

The problemetic code is presented below:
Code:
The output is always
Quote:
Isn't that weird? Because text_val is assigned the value of innerHtml. So if text_val is shown to be 50 then why is innerHtml shows value as 5? The div always shows 5 seconds.
The full context is given below.

I was playing around with some onmouseover/onmouseout and setting innerHTML to various strings depending on what has been mousedover/out. The DIV for the innerHTML was above the items being onmouseovered/out and because the strings sent were of different lengths, sometimes a one or two line wrap would happen and everything below it would be resized accordingly creating a horrible effect. For reference, what is a good way to approach building pages which are immune to this effect?

I'm populating a table from my database using .Net and within this application, I am then comparing the value the user has entered to the first column of every table row in the pre-populated table.For some reason, when I loop through each row in the table and return the value in the first column...the value always stays the same when in fact i know its different by just looking at it on the screen and in the html source.I throw up an alert message for each time it loops, and it its looping the correct amount of times, just not returning a the correct value.
HTML:
<table id="tblProducts" name="tblProducts">
<tr>
<td id="tdProdNum">

I found a function online that allows me to swap text onclick and have amended it as follows:
Code:
function swapText(obj, n) {
if(obj.oldText){
obj.innerHTML = obj.oldText;
obj.oldText = null;
[Code]...
I have this partially achieved when clicked, any number will indeed "turn into" an h1'd representation of itself but I can't get the other links in the group to disappear when the h1'd number appears (onclick).

I'm using an i-frame to grab a server-side text file and display its content
elsewhere in the html document. On change of the i-frame source, I want to
access its innerHTML.
The i-frame source changes just fine and even displays the source; the glitch
is in accessing the innerHTML for that new i-frame src file. It requires *TWO*
clicks of the onClick element to get the correct innerHTML (with just one
click, the source will change, and display the new file in the html document;
however, the innerHTML is still that of the old source file for the i-frame).
This does not appear to be a loading problem with the new src file into the
i-frame. (ie: setTimeout on a function to get the innerHTML after the src file
loads does not work).
So the question is: how can I get the i-frame source to change AND access the
new src file's innerHTML with one click?? Code:

I am nOOb to Javascript and wanted to extract HTML from another website. I tried this by using an iframe that opened up the desired webpage and called a script to read the innerhtml of the frame using the onLoad event.
It fails however with a Permission Denied error when trying to extract the html via the script (see code below).
Not sure if I am doing something worng, or if this is just not allowed on ClientSide scripting (I can appreciate writing isn't) but not being able to read.
Anyway, assuming this can't be done in this manner, is there another way in which it might short of using server side scripting?
<SCRIPT language = "Javascript">
function readFile()
{
doc=window["myframe"].document.body.innerHTML;
//TBD...
}

Here is my problem in a nutshell: a script to model dynamic table
extension. It works under Firefox. But IE just aborts, complaining about
an "unknown runtime error" in the line with "innerHTML". Why?
<html><head></head><body>
<script language="javascript">
function extend() {
var tb = document.getElementById('thetable').tBodies[0];
var newrow = document.createElement('tr');
tb.insertBefore(newrow,tb.rows[tb.rows.length-1]);
tb.rows[tb.rows.length-2].innerHTML =
'<td>A</td><td>dummy</td><td>row</td>'
}
</script>
<table id="thetable">
<tr><td>1-1</td><td>1-2</td><td>1-3</td></tr>
<tr><td>2-1</td><td>2-2</td><td>2-3</td></tr>
<tr><td>3-1</td><td>3-2</td><td>3-3</td></tr>
<tr><td colspan="3"><a href="javascript:extend();">extend</a></td></tr>
</table>

I have a page, with 3 IFRAMEs on it. From one of these IFRAMES, i am trying to append to the content of another IFRAME.
This doesnt work:
top.frames[0].document.getElementByID('chat').innerHTML+= "new content"
any thoughts?
I know I'm referring to the right frame, because
top.frames[0].document.location.href = "someotherpage.html"
does work

This is what im trying to achieve. At the top of my page there is some
search functionality, through which you cause to be loaded a string
representing an HTML page. Below this and occuupying about 80% of the
window real estate, there is a DIV. There is also a toggle button with
two options "Code View" and "Text View" as I have named them. Depending
on which mode you are in, you can see the block of HTML either as code
(in other words the tags are not rendered. You see the HTML as it
exists.) or as text (rendered HTML). Consider the following code, which
is a simplified version of the page.
<script language="javascript">
var mode = "code";
var s = "<html><head>
<style type="text/css">
My Stylesheet
</style>
<title>
MyTitle
</title>
</head>
<body>";
function ViewDoc()
{
if(mode == "code")
document.getElementById("docArea").innerText = s;
else
document.getElementById("docArea").innerHTML = s;
}
function ChageMode()
{
if(mode == "code")
mode == "text";
else
mode == "code";
}
</script>
<HTML><BODY>
<table>
<tr>
<td>
<input type='button' onclick='ViewDoc()' value='View Document'>
<input type='button' onclick-='ChangeMode() value='Change Mode'>
</td>
</tr>
</table>
<div id='docArea'/>
</BODY></HTML
The variable s contains an actual example of some HTML im trying to
load here (with the contents of the stylesheet omitted.)
Now, the following works fine in Internet Explorer. It does not work at
all in Mozilla Firefox. In firefox, for example, I have to cut out the
stylesheet, or the entire page goes fubar. Without the embedded
stylesheet, the "text" view (rendered html) works just fine. But the
"innerText" does not work in Firefox, and im not sure how to replicate
it.

I am generating a string from AJAX data which contains forms and submit buttons. I then try to assign this string to a div using innerHTML. This works fine in IE but Firefox strips form tags and every thing in between form tags. How to solve this issue
Example code:
str = "<form action='somepage.php' methid=post><input type=text name=some_field><input type=submit value='Submit'></form>";
document.getElementById('some_div').innerHTML=str;

I am encountering this problem with Firefox, but no problem in IE. I have in a hidden <div> dynamically generated select options intended for re-use by dynamically created forms on page.
For Example:
<div>
<option value="1">xxx</option>
</div>
With javascript, when I use getElementById() to get the <div>, and then get the innerHTML, on IE I get the content just as they were generated out, and I was able to put this into an empty <select> and everything works. But when I try the same in Firefox, the innerHTML returns only the text part of the content. The "<option value="1">" part has been stripped off. Wondering if there's a solution to get around this?

I'm having an issue with Firefox and the innerHTML code. My index file has the following html body code in it:
Code:
<div id="testBox" style="text-align: center; color:white;">
test text
</div>
Then, in a separate html document loaded through an iframe, I have the following code that works great in IE but not in Firefox:
Code:
<SCRIPT type="text/javascript">
function ChangeML(){
parent.testBox.innerHTML ='text has been changed';
};
</script>
The function ChangeML is called on a click event using MooTools, but I figured that part isn't what's causing the problems because everything else works fine. No error seems to be reported ... it just skips right over this piece of code.

I can read the contents of an iframe:
HTML Code:
var iframe = document.getElementById("message");
var iframeContents = iframe.contentDocument.body.innerHTML;
var txtarea = document.getElementById('message2');
txtarea.value = iframeContents;
This will read the contents of an iframe, and write it to a textarea.
iframe is editable, and content is entered by the user. Still, this works.
But, below code is not working. Trying to put some content to an iframe, with the same innerHTML method above. It returns no errors or warnings. Even last alert() displays "<div>lorem ipsum</div>", but iframe is empty, it displays nothing..
HTML Code:
var textContent = "lorem ipsum";
var iframe2 = document.getElementById('message');
iframe2.contentDocument.body.innerHTML = '<div>'+textContent+'</div>'
alert(iframe.contentDocument.body.innerHTML);

The following extremely simply JavaScript code:

<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta http-equiv="Content-Style-Type" content="text/css">
[Code]....
alerts the innerHTML content in all the browsers. Except in Firefox 3.6.8, which alerts a blank value. What the f?:confused: I know that innerHTML is not a standard DOM method, but it used to be a crossbrowser one since FF 1.5, right? Edit: It does not work even in case of firstChild.nodeValue or firstChild.data. FF 3.6.8 says that the DIV element has no first child, which is amazing.
