Getting Href Attribute Of <base> Tag?

Jul 20, 2005

I'm trying to get the href attribute from the base tag in the document
head. The following does not seem to work... any ideas what I'm doing
wrong?


if(!(document.getElementsByTagName) ||
!(basehrefs = document.getElementsByTagName('base')) ||
!(basehrefs.length) || !(basehrefs.length > 0) ||
!(basehrefs[0].getAttribute) ||
!(basehref = basehrefs[0].getAttribute('href')) )
basehref = ''

This is essentially a very cautious version of:

basehref = doument.getElementsByTagName('base')[0].getAttribute('href')

The big hairy if just provides checks to make sure everything can be
done and provide a contingency if it doesn't...

Drop Down Multilevel Vs. Base Href

Jul 20, 2006

I need to make a drop-down menu for my multi-level website. I need all the links on this dropdown to work on every page, no matter on what level (subfolders, sub-subfolders etc.) it's called out.

i have a base href tag on every page set to my index page the links in my drop down menu look like this location='supplies/painting.htm'

where 'supplies' is the folder contained in the main root folder, so it should be working but it's not. Whenever i click on this link while i'm in the 'about_us' folder, it tries to bring out the page 'about_us/supplies/painting.htm'

Only thing left to add is that this script is included "as is" with dreamweaver, and thats why i have no idea how it works. I'd code it myself, but the client wants it that way Code:

BASE HREF And A HREF="#" Onclick="..."

Jul 6, 2006

I've looked for this and I wouldn't know what the best practice would be
for solving the following problem.

We use a BASE tag in our HTML pages. Now we have some links that use the
<A HREF="#" onclick="...">Hello</Amethod to invoke a JavaScript.
However, because of the BASE tag, when clicking a link containing only a
# as 'href' it will load the root index.html file. What I want is it to
do nothing and execute the onclick handler.

Now I have two possible solutions:

- Replace the # with javascript:... and remove the onclick handler.
- Replace the A HREF by a SPAN having the same style as a link.

Both however, I've learn it isn't good practice to use javascript: in a
link. The SPAN as link would be a sort of Sim-HREF, which will probably
end up being trouble (span:hover anyone?). Anyone has a viable solution,
cause I must be missing something.

Change Href Attribute With Two Dropdowns

Nov 24, 2005

I am in a problems here trying to generate link by two dropdown boxes. So, I wanted it to be like when user selects some option from dropdown one the href attribute changes, index.php?staticvar=something&dynvar1=something, that is something I have already managed to do:

function change_href(id)
{
if (id != '')
{
var dynvar1 = document.getElementById("s"+id).value;
document.getElementById(id).href = "index.php?staticvar="+id+"&dynvar1="+dynvar1;
return;
}
else
{
return false;
}
}
This works perfectly for me, but now I need to modify the href with another variable, so it would be needed to be like:
index.php?staticvar=something&dynvar1=something&dynvar2=something2

The problem is that I don't know how to make it the way that user can change their selections, for example if user first selects (from dropdown) dynvar1 to be "test" and dynvar2 to be "test3", but then changes hes mind and decides to re-select dynvar2 to be "test4". It would be needed to be like only the dynvar2 part of the href changes with proper value (not changing the dynvar1 or staticvar).

I managed to make it changeable but it was like this:
index.php?staticvar=something&dynvar1=something&dynvar2=123&dynvar2=123

So, it didn't update the dynvar2 part, but instead just added another dynvar2 variable.

JQuery :: Href Attribute IE Vs Standards Browsers

Aug 30, 2010

I'm having an odd issue that i can't recreate in jsbin.i have an anchor tag:

<a class="navigateToCategory" href="#523">Instruments</a>
and the code below:
$('.navigateToCategory').bind('click',function(e){
e.preventDefault();
alert($(this).attr('href'));
});

IE will give me [URL] while all other browsers give me "#523". I tried to recreate this using a small test case, but i can't do it. IE always returns the "#523" just like all the other browsers. here's a jsbin of it workinghttp://jsbin.com/unowe3/13 why .attr('href') would be different in IE vs Other browsers on my page but not jsbin? i'm using the same doctype and version of jquery, and identical code. i can't think of any code that i could have written that would affect how .attr('href') works. Edit: i did build a "hacky" solution for it by using $.browser.msie and an if statement, but it doesn't make any sense to me why it would be different in my situation vs any other.(not to mention, if it for some reason starts working properly, the "hacky" solution will cause it to not work)

I'm pretty green to jQuery. I have a .load() calling in some content that has some links within it. After that content is loaded, am I able to change the attributes of those links? This is how I'm loading in the content:

Which contains:
<a class="table_button0" href="#"></a>
<a class="table_button1" href="#"></a>

Aug 28, 2010

Right, so there are a bunch of links in this format: <a href="/profiles/########">username</a>

I'm using greasemonkey, and what I want to do is go through and get all of the /profiles/######## part of the anchor tag. I'm using Regex and I can't seem to get a match.This is what I have so far:

function ok() {
var names = document.getElementsByTagName('a');

what is actually desired is I want there to be a way I can select these somehow as well..

JQuery :: Matching All Anchor Tags With "http://" In The Href Attribute

Apr 19, 2010

I want to be able to match all <a> tags on a Web page that are external links, which would be signified by the href attribute starting with "http://", obviously. Then I want to add an attribute to the matching tags.

I ran across this script that is supposed to do that:

<script type="text/javascript">
$(document).ready(function(){
$('a[href^=http://]').attr('target','_blank');
});
</script>

But it doesn't work. I don't understand regex very well yet, so I'm not sure if that part of it is right, but the jQuery syntax looks correct to my inexperienced eyes.

I know jQuery is working on the site already, the script is below the call the the jQuery library, and yes, I do have the script in the Head tag of the page...

Overriding Methods In Sub Or Base Classes

Jan 20, 2011

In class based languages you can override methods in subclasses like so:
class BaseClass{
methodA(){
print( name() );
}name(){
return "--base--class--";
}}
class SubClass extends BaseClass{
name(){
return "--sub--class--";
}}

So the following code prints "--sub--class--"
(new SubClass).methodA();
So even though methodA belonged to the BaseClass, it called the overridden version found in SubClass. Would the equivalent code in Javascript print "--sub--class--" or "--base--class--" ?

JQuery :: Href In Output Code Causing $getJson() Function To Try To Load Up A File With Href In Url

Jul 12, 2010

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.

JQuery :: Passing Base 64 Encoded String Through Ajax?

Feb 1, 2011

I have an image that is encoded as a base 64 string, and I'm having trouble passing that a WCF service using $.ajax(). I initally tried using JSON to pass the argument to the web service, but I kept getting 400 Bad Request errors for anything of reasonable length (if I just pass a test string in, it makes it through, of course). I've tried calling encodeURIComponent on the string before stringifying it, but that hasn't helped. I've also tried various content types ("application/json; charset=utf-8", as well as whatever the default is) and that hasn't made a difference either. Unfortunately, the request is being made through a mobile phone, so debugging options are few. Is there an upper limit to the size of the argument that I'm passing in this? The strings can be a few hundred kb at the low end up to maybe 1 or 2 mb at the high end.

Here is a snippet of the code I am using:

$.ajax({
type: "POST",
url: "http://www.myserver.com/MyService.svc/MyFunction",
cache: false,

[Code]....

No matter what the string consists of, it errors would with a 400 Bad Request error. No further information.
