Suppose I have the following inside a function:Code JavaScript:document.getElementById('display_content').innerHTML = "hello";The above works.However, when I define it like the following it says display_content is null on firefox error console.
Code JavaScript: var display_content = document.getElementById('display_content');
I have been charged with using CSS to change the visited state of a hyperlinks that use "return false" in the href to cancel the redirect.The CSS is simple, the other three states (L, H, A) render properly. The visited state will not. I am inclined to say that this task is impossible without more JS due to the fact that the click event is effectively cancelled to and the redirect.[code]
This seemed like it should be so simple. It works fine in Firefox, but not in IE. The goal is to disable the form's Submit button, until the question is answered. (The alert is for troubleshooting.)
I want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.
In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.
I keep getting an error stating "getElementById("ballElement") is null, but I have a div with that exact id. I have looked at the JS script before that line, but found no errors there either. Please take a minute to see if you find something.
I create an xml file in a text editor: <?xml version="1.0" encoding="utf-8"?> <elts> <elt id="1" class="c1">content1</elt> <elt id="2" class="c1">content2</elt> </elts>
Then I load the file via xmlHttpRequest into xmlData variable. Why does xmlData.getElementById(Ƈ') return null and xmlData.firstChild.childNodes[0].className returns null also?
I have a table with td consisting of lists with <select></select>. When I do a document.getElementById("element").innerHTML I don't see the selected item. IOW, the innerHTML is not dynamic. Is there some way to get the most recent selected without traversing through the list's options.
Either I'm having a really dim Friday, or something strange is going on. I'm trying to add a method to the Validator plugin, using the following regex:
I am having a problem accessing and element by ID in a script that runs via 'window.onload' at the end of all my script definitions. Do the HTML elements exist at that point or should I look somewhere else for a bug?
I'm trying to add a class to a <li> where the href within it contains a string. I can apply the class to the anchor without a problem, but I can't seem to select the parent. Is an anchor a child? <li><a href="random.xls">Random Stuff</a></li>
In this case, since the href contains .xls, I'd like to be able to add a class to it. I've tried a variety of things, most recently this, but no luck: $('li has(a[href$=".xls"])').addClass('excel');
I'm using the following code (simplified version) to call a Json file, parse it and on each iteration, create a div with an ID of "tab". I'm using this with jQuery UI .tab() to create a listing with entries which have three tabs. Anyhow, the principle seems to work except that when I examine what's happening behind the scenes using Firefox console, I see that each href in the html code produced is causing the Json function to re-fire using the href as it's url target.

How can I set a href or onclick function for an "a" element that passes information to the function?I have a function showpage() that is called whenever one of a number of buttons are clicked. I need to pass information from the button clicked to that function.
I have an index.htm page ready. I want to be able to put in javascript code into the HTML coding that will write the ip address of the actual server that is hosting the website into a hidden text box. Then I want to insert this ip address into a hyperlink in the original index.htm to link to another html page (this will be a SSL secure page instead i.e. [URL].Also vice versa. (With SSL index.htm page have code that writes ip into hidden text box then hyperlink to the original http index page)
i have a script that changes an image in the main frame when you hover over a hyperlink in the navigation frame. however i would like to extend this and make the image that appears to be a hyperlink. the code i have is below. the navigation frame:-
I am trying to find a way to create a hyperlink that includes the URL of the current page as a query parameter, eghttp://website.com/ref?url=http://mywebsite.com/thispage.htmwhere the bit in green is generated from the URL of the current page rather than hard-coded into the HTML. The reason for this is that I am putting it into a page fragment to be called up with a virtual include and will appear on hundreds of pages, so I really don't want to have to hard-code the link every time!I don't use PHP or any form of CMS, so I think my best bet is to use Javascript (it's a non-critical function so I am not too worried if it fails for people without JS enabled). I think I could probably cobble something together using document.write but I suspect there is a better way of doing it.
I have code that basically will bold a hyperlink when a check box is checked. For example I have checkboxes that say;
Eggs [] Waffles [] Ham [X] Wheat Bread[X] White Bread[] Cheese[X]
When those boxes are checked it will bold links as follows
Breakfast sandwich Lunch Sandwich Dinner Sandwich
What I'd like to do is while the check boxes are being checked it'll highlight those hyperlinks that fall into the checked values. When it reaches a value that it doesn't fall into it will unbold itself. So far I have code that when a a certain combo of boxes is checked, it'll highlight, but like I said. I'd like to keep the links highlighted until it reaches a condition that'll make it unbold. Code:
I would like to make an hyperlink invisible, or disabled, with a click. The hyperlink opens a new window (target = _blank) and once the new window is shown, I don't want the hyperlink to be active anymore.
