to append a parameter string like: '?key=val' to the currenturl and the value for the key changes based on the user input. Isthere any jquery utility that does the base url extraction fromwindow.location, so that I can append the '?key=val' to that?

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.
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...
If I have the following
2^n=a
javascript:Math.pow(2,n)=a;
and I now a how do I then find n with javascript?.
I am trying to think of a good way to write some javascript that checks to see if the url entered by a user is base directory url and not an individual page. For example,
I want them to enter something like:
http://www.example.com
And not an individual page like:
http://www.example.com/index.html
I am using a generic Template in a site where different domain names may enter at different levels of a web site.By using some CSS in my <header> to set the base url.I am able to refer to the address of an image by just having.By changing the BASE URL I am able to change which image will display.So I need to obtain the URL address that the viewer, came into the web site on, and then set the BASE URL.
View 2 Replies View RelatedI 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:
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--" ?
Got an assignment for a javascript class and I have been banging my head against the wall for a week now.[code]In the main page I have tried several different ways to access the "src" property of the image, none of which I am 100% sure is correct. I think the problem is in the main page, in that I am not accessing the image right, but I could be wrong. I have spent hours on google and digging through the book, but I am still coming up empty handed.

I came across a very odd browser behavior when trying to modify a css class using javascript and at the same time having a base html statement in my html file.Without the base html statement, all browsers work fine and I can change the css class definition using javascript easily.With a base html statement, only FireFox still works while Internet Explorer and Google Chrome dont work anymore. If there is a cross-domain issue, while one browser does work and the others dont? An example of what I'm talking about, with the base statement:

View 2 Replies View RelatedI need to be able to get the value from the input box below to send a PHP script. This value is generated based on other fields in the form using Javascript.
<input type="text" name="need" value="0" onFocus="this.blur()">
The value of "0" is auto set because it starts out as 0 and as you fill in other details the number increases. I have tried to remove the "0" and continue but when posting to a PHP script ($_POST['needs']) it shows up blank.
