Firebug Prevents Page Interaction	View Content

Hey all,

Whenever firebug detects a js error on a page, it prevents you from interacting with the page, so you can't scroll, you can't click, you can't do anything except close the window. Anyway around this? Thanks.

Please advise me:

I've successfully called a variety of functions that have no parameter value such as:
function expand() //expand() in this line is merely an example
But I'm unsuccessful calling a function with a paramter value such as:
function expand(id)

Here is the the call line:
document.addEventListener("DOMContentLoaded", expand(id) , false);

Here is the Function:
function expand(id)
{
for (var i = 1; i<=10; i++)
{
if (document.getElementById('smenu'+i))
{
document.getElementById('smenu'+i).style.display='none';
}
}
if (id)

Nested Contenteditable Element Prevents Hyperlink Default Behavior

Similar Tutorials

View Content

I've got the following problem. In IE if a contenteditable element is nested inside a hyperlink, clicking on the element prevents the hyperlink default behavior, i.e. navigation to another document. In FF it works fine. How can I solve the problem? Just removing the contentEditable attribute is not a solution since I want this behavior (navigation to another document) only when user clicks the content-editable element with pressed Ctrl key.

Thanks.

Javascript Error In Firebug, Please Help!!!

Hello.

Recently my company's site has been acting funny. Images on the page bladv.com/work aren't displaying except in older/non-updated browsers. When I ran Firebug to check the javascript, I got the following message twice.

"NetworkError: 404 Not Found - http://bladv.com/assets/_cache/00000000009939b9184d06e0feb33450dc78b54e11.js"

Does anyone know why I'm getting this code, and would this be the reason images on the page bladv.com/work aren't showing up?

If this is the problem, how do I fix it? I tried adding the js file into the cache folder but I'm still getting the error codes in Firebug and the images are still invisible. Hope that makes sense, I'm very very new to javascript.

Thanks

I am trying to debug this with FireBug

Code:

    //create an element
    var element = document.createElement('input');
    //set some attributes
    element.setAttribute('type', 'button');

    document.getElementById('myDiv').appendChild(element);
    //uses EventUtil to attach an event listener

}

var EventUtil = {
    (2)addHandler: function(element, type, handler) {
        //check if the element and the browser support DOM Level 2 event attachment
        //if the user is not browsing with IE
        if (element.addEventListener) {
            element.addEventListener(type, handler, false);
        }
        //if user is browsing with IE
        else if (element.attachEvent) {
            element.attachEvent("on" + type, handler);
        }
        //if user is using a browser that only supports DOM Level 0 event attachment 
        else {
            element["on" + type] = handler;
        }
    },
    
    removeHandler: function(element, type, handler) {
        //check if the element and the browser support DOM Level 2 event attachment
        //if the user is not browsing with IE
        if (element.removeEventListener) {
            element.removeEventListener(type, handler, false);
        }
        //if user is browsing with IE
        else if (element.detachEvent) {
            element.detachEvent("on" + type, handler);
        }
        //if user is using a browser that only supports DOM Level 0 event attachment 
        else {
            element["on" + type] = null;
        }
    },
    
    preventDefault: function(event)
    {
        if(event.preventDefault)
        {
            event.preventDefault();
        }
        else
        {
            event.returnValue = false;
        }
    }
};

I put a breakpoint on the line marked with (1), I am trying to go to line (2) with all the available options FireBug gives, but unfortunately I get the end of chapter12_nodeOne function. Any ideas why?

Ok so I'm playing around with writing scripts reading through JavaScript: The Definitive Guide and I'm on the Section "Relationships Between Frames".

'$active Is Not Defined' Firebug Error

Similar Tutorials

View Content

I'm getting an '$active is not defined' error, which makes sense because the method that defines it isn't called till 10 seconds after I check if it is defined below. But that's the point. I'm actually checking to see if it is defined, and if it's not, then I defined. However, firebug still gives me the error for this:

Code:

if ($active == undefined) {
						$active = $('.paging a.active');
						}
						var triggerID = $active.attr("rel") - 1; 
					        var image_reelPosition = triggerID * imageWidth;

I also tried:
if ($active === undefined)
if (!$active)

But nothing works. I'm just trying to check if it's not defined, then define it.
Yet it won't let me check if it is undefined because it is telling me it's undefined despite the fact I'm checking for that very reason.

Thanks for any response.

Jquery - Firebug Gives An Error/warning!

Similar Tutorials

View Content

Hello.

I'm coding a simple hover-opacity thing for some images on my site on the navigation bar.
Although I'm receiving this message in my Firebug.

uncaught exception: Syntax error, unrecognized expression: .

Here's the navigation code:

Code:

<div class="navigation">

<a href="home"><img class="home" src="images/navigation/home.gif" /></a> - <a href="home" class="home">Home</a>
<a href="news"><img class="news" src="images/navigation/news.gif" /></a> - <a href="news" class="news">News</a>

</div>

So the effect I've made is, when I hover the image, its opacity gets set to 1. And when I move my mouse away the image changes opacity to .5

And when I hover the text "Home" or "News" the same effect happens with the image.

And here's my jQuery:

Code:

$(function(){	
	$('.navigation img').css({
		opacity: .5
	});
	
	$('.navigation img').hover(function(){
		$(this).stop().animate({ opacity: 1 },300);
	}, function(){
		$(this).stop().animate({ opacity: .5 },300);
	});
	
	$('.navigation a').hover(function(){
		var imageClass = $(this).attr('class');
		
		$('.navigation img.' + imageClass).stop().animate({ opacity: 1 }, 300);
	}, function(){
		var imageClass = $(this).attr('class');
		
		$('.navigation img.' + imageClass).stop().animate({ opacity: .5 }, 300);
	});
});

I can't seem to find the error in my script(s).

Any help is appreciated.

EDIT: Apparently the error appears when I make anchor tags around the image.

Code:

<a href="home"><img ... /></a>

This gives the error. :S

Code:

<img ... />

But this doesn't? How can this be?

Firebug Inspect Element Feature Using The .net Framework And Javascript

Similar Tutorials

View Content

Hello JavaScripters! I was hoping you could help me with an application I'm working on using C# and the .NET Framework that incorporates Javascript. I'm trying to do something similar to to the FireBug / Firefox Inspect Element featu

I came across http://www.selectorgadget.com/ which is exactly what I'm trying to do. It's in Javascript and after looking through the source code for the past 2 hours I still don't have a clue how to incorporate it into my program...

From what I can tell it uses tokenizing and recursive analysis of DOM elements to figure out CSS selector paths: http://www.selectorgadget.com/stable/lib/dom.js.

Here is what I have so far. The javascript code highlights HTML elements such as a <table> tag and changes the border and background color.

Code:

  document.onmouseover = dohighlight;
  document.onmouseout = dohighlightoff;

  var BGCOLOR = "#444444";
  var BORDERCOLOR = "#FF0000";

// Highlight <table> in grey 
  function dohighlight()
  {
    var elem = window.event.srcElement;

    while (elem!=null && elem.tagName!="TABLE")
        elem = elem.parentElement;

    if (elem==null) return;

    if (elem.border==0)
    {
        elem.border = 1;

        // store current values in custom tag attributes
        //
        elem.oldcolor = elem.style.backgroundColor; // store backgroundcolor
        elem.style.backgroundColor = BGCOLOR; // new background color

        elem.oldbordercolor = elem.style.borderColor; // same with bordercolor
        elem.style.borderColor = BORDERCOLOR;

        var rng = document.body.createTextRange();
        rng.moveToElementText(elem);

// Make a red border around <table>
  function dohighlightoff()
  {
    var elem = window.event.srcElement;

    while (elem!=null && elem.tagName!="TABLE")
        elem = elem.parentElement;

    if (elem==null) return;

    if (elem.border==1)
    {
        elem.border = 0;

        // recover values from custom tag attribute values
        elem.style.backgroundColor = elem.oldcolor;
        elem.style.borderColor = elem.oldbordercolor;
    }
  }

Any ideas on how to incorporate the Selectorgadget into my program would be greatly appreciated!

Loading External Js Before Page Page Load (specific Span Element)

View Content

Hello. My goal is to load the JS for a specific element before displaying that element. I integrated a third part script, and it works well. I set the timer he

The JS is in my heading as <script type="text/javascript" src="countdownpro.js"></script>

About mid-body I have: <span id="countdown1">2010-07-20 00:00:00 GMT+00:00</span> which allows for the setting of a target date to countdown to.

When the page first loads it shows the above long format target time, until the js/meta tags kick in to modify it to just show the actual countdown as 00:00:00.

I have attached countdownpro.js to this post. I tried shifting the function CD_Init() to the top of the script, and also appended it inline with the .html. I tried setting the big external script to "defer", but neither arrangement worked. I also tried placing the src file right at the top.

I appreciate your help.
