Hi,
I have an application in which a popup window is opened from main window, from that popup window on clicking a button, the control goes to a servlet and after some calculations the control returns to the popup window. This works fine in IE6. But the same code behaves improperly in IE8. In IE8 on clicking button on popup window instead of control coming back to same popup window a new popup is opened. Can anybody help me on this?

I am trying to dynamically add rows to a table when the user clicks a button. here my function

Code:

	if(addTlFocusAreaCount <= 5)
	{
		//Create new Title row
		var titleRow = document.createElement("tr");
		var titleCol = document.createElement("th");

Compatibility Problems With Ff.

Hi, I have a piece of code that when executed will change the .onclick and .value of a button,

Code:

/* JAVASCRIPT */

function selectAllDays() {  
	var len = document.booking.days.length;
	for (var i=0; i<len; i++) {
		document.booking.days[i].checked = true;		
	}
	changeDaysButtonD();  
}

function deselectAllDays() { 
	var len = document.booking.days.length;
	for (var i=0; i<len; i++) {
		document.booking.days[i].checked = false;		
	}	
	changeDaysButtonS();  
}

function changeDaysButtonD() {   
	var obj = document.getElementById('selectall');
    obj.onclick = deselectAllDays;
	obj.value = "Deselect All Days";
}

function changeDaysButtonS() { 
	var obj = document.getElementById('selectall');
    obj.onclick = selectAllDays;
	obj.value = "Select All Days";
}

Code:

HTML

<input type="button" id="selectall" name="selectall" value="Select All Days" onclick = "selectAllDays();"><br/>
<input type="checkbox" name="days" value="Monday">Monday<br/>
<input type="checkbox" name="days" value="Tuesday">Tuesday<br/>
<input type="checkbox" name="days" value="Wednesday">Wednesday<br/>
<input type="checkbox" name="days" value="Thursday">Thursday<br/>
<input type="checkbox" name="days" value="Friday">Friday<br/>

So, when the button is initially clicked it runs the selectAllDays() function, which will also run the function to change the state of the button to "Deselect all days" however when I run this in FireFox it gives the error of
Error: selectAllDays is not defined
Source File: http://davidc.herobo.com/groupsite/booking.html

Though in Internet Explorer this runs fine and selects/deselects the checkboxes without any problem.

I'd like to know if anyone knows why it won't work in FireFox?

Help would be much appreciated,
Thanks, Dave.

EDIT: i think the problem was i had an html element named 'comment' so IE was getting confused when i made a js variable 'comment'
(don't use IE it is the worst browser)

i am in the process of debugging a website, it works wel in Google Chrome and firefox but not in IE
i am putting all the relevant code below.
this is in the head tag, and is the only JavaScript executed when the debugger show the error
Code:

function first_run(){
answer_state=document.getElementById('state');//set node for 'show_answer' function
answer_ab=document.getElementById('ab');//set node for 'show_answer' function
answer_capitol=document.getElementById('capitol');//set node for 'show_answer' function
answer_next=document.getElementById('next');
comment=document.getElementById('comment')//line marked with error
ui=document.getElementById('UI');//sets 'ui' to form location
score_right=document.getElementById('right');//returns null
score_wrong=document.getElementById('wrong');
score_right=score_wrong.previousElementSibling//score_right work around
score_show_ans=document.getElementById('show_ans');

runs above code on page load
Code:

<body onkeydown="if (event.keyCode == 13){check()}" onload="first_run()">

in body tag, node that erred line refers to.
Code:

<div id=comment>
</div>

the error message in IE's developer tools debugger is "Object doesn't support this property or method" States javascript.html, line 395 character 1"

i've done all of my coding in Chrome and have no expirence in IE's syntax, any ideas what the problem is?

Js/iframe Compatibility In Ie8?

Similar Tutorials

View Content

Hi--

I have the following javascript which is setting up a quiz (delivered from off-site) into an iframe. The javascript code determines if the visitor has Flash or not, and then sets up the page, on button click, to deliver the appropriate version of the quiz into the iframe.

For some reason, this code works in everything (it seems) except IE8. In IE8 without Flash, something (perhaps in the code itself?) kicks the viewer into a blank page. If someone could just test the URL below and tell me if they get the same problem, that would help! Maybe (I am thinking) it is because the computer I tested it on did not have JS enabled? Or maybe there is something in the code? Or maybe with the quiz delivered from off-site?

Here is the code:
Quote:


<article id="page_7c">
<div class="box" id="page1">
<a href="#page_1" class="close"></a>
<div class="wrapper pad_bot1">
<div class="grid_16 prefix_4">

<p></p>
<div id="tester">

</div>

</div>
</div>
</div>
</article>


<SCRIPT>

</SCRIPT>
And here is the URL of the site:

Quote:
http://www.ABCsofUFOs.com
If you click on the link bottom left ("Test Your Knowledge of UFOs") that should send you to the appropriate version of the quiz.

Many thanks for any help!

Newbie Stuck On Compatibility Problem

I adapted (well, attempted to, at least) a quote/testimonial rotation script to fit into my website. The script works PERFECTLY on Firefox but after making my modifications, I killed it in IE...and being a total n00b to JavaScripting.....I'm totally stumped.

In Firefox, the script shows at the proper height. In Internet Explorer, the script is only shown at ~40 pixels and doesn't seem to be rotating through the different quotes (it still fades but it fades the same quote back and forth).

The obvious question: HOW DO I FIX IT?!!?

Original script was found at: http://www.caodesigns.com/blog/tutor....php?postID=33

My script is at: http://www.digitalctrl.org/help.html (right sidebar, in the "Testimonials" box).

But something I want to know for future reference.......what is it that causes things to be formatted differently across browsers? This cross browser INcompatability is giving me grey hairs.

I've been lurking around your community for a while now.....I hope you gents don't mind my first post being a question.

If I need to reformat my post or do anything else to get assistance, please let me know so I can take care of it.

Settimeout And Elemid Compatibility Problem

Hello all.

I am doing an experiment with setTimeout for a much larger project and cant seem to get this bit of code working. What is "supposed" to happen is on hover the div goes black, and on removing the mouse it turns red after 1 second. however, it doesnt work. ive tried a bunch of variations but nothing gets it to work. i want to line up a bunch of divs and not need to write a seperate function for each one. any ideas?

here is the HTML:

Code:

<div id="0" onMouseOver="blackit('0')" onMouseOut="fadeit('0')"></div>
<div id="1" onMouseOver="blackit('1')" onMouseOut="fadeit('1')"></div>
<div id="2" onMouseOver="blackit('2')" onMouseOut="fadeit('2')"></div>
<div id="3" onMouseOver="blackit('3')" onMouseOut="fadeit('3')"></div>

here is the JavaScript:
Code:

function blackit(elemID)
{
document.getElementById(elemID).style.backgroundColor="#000";
}

function fadeit(elemID)
{
setTimeout("document.getElementById(elemID).style.backgroundColor='red'", 1000);
}

there is some CSS but nothing crazy. it should work but it doesnt. the black on hover works but then it either stays black or goes red immediately, not waiting the 1 second.

thanks

Onmouseout On Div Tag--bubbling Problems, Cross Browser Compatibility?

Similar Tutorials

View Content

Hi all, I am having trouble with an onmouseout event on a div tag. I have read about bubbling a little, and put to use some information I found on the internet, but I still can't overcome a few problems.

What I am trying to achieve is that the addStyleDiv function will only call the addStyle function if the user mouses out of the 'rollover' div. As the code stands, the addStyleDiv function is called when any element within the div is moused out (this is expected--bubbling) and the addStyleDiv function handles these instances properly. However, when mousing out of the rollover div, the rollover div is never the source element that triggers the onmouseout event. There is no empty space in the rollover div, that is, it is entirely filled with elements, so that could be part of the problem, but shouldn't bubbling cause the event to be triggered twice-once for the internal element and once for the div itself?

I would also be interested in knowing if the method by which I am handling the events is reliable on most browsers or if someone with more expertise can offer a suggestion to increase cross browser compatibility.

Thanks a million in advance.

HTML
Code:

<div id="rollover" onmouseout="addStyleDiv(event,'feat_main');">

Safari Compatibility Issue With Dynamic Population Of Selects

Similar Tutorials

View Content

Anyone have any issues with Safari in relation to javascript compatibility?

I have a page that loads dynamically through user selections as follows:

There is a set of three radio buttons. The user selects one and a div opens revealing a select box populated with entries related to the radio button selection.

When the user makes a selection from the select box, one of two things happen. 1) If there are child records relating to their selection, a second div opens revealing another select box containing the child entries relating to the first select box choice. Or 2) if there are no child entries relating to the selection in the first select box, a div opens displaying a description relating to the selection they made in the first select box.

The data is all coming from prepopulated javascript arrays.

This works like a dream in IE and Chrome. Unfortunately, when we were in the final stages of testing before release to a live environment, we discovered it works in Safari only as far as the user makes a selection from the three radio buttons driving the opening of the first div layer containing the first select. At this point it stops working completely.

On top of that, I can not find where in the latest release of Safari, that I can see any javascript errors (or if I even can). I am REALLY in need of help. Anything you can offer?

Thanks!!

Does anyone know how to make URL links that use Javascript still work when

The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version.

I tried the <script><noscript> tags, but I'm not sure if I'm using it
correctly, as my URL completely disappears.
