JavaScript - Xmlhttp In Ie

So, my url looks like index.php?id=2&name=test&place=14

There is a next link that uses an onClick= to call an ajax function. This ajax function runs this php script (bar_next.php) behind the scenes.

I need to put just the id value into the code below.

Code:

xmlhttp.open("GET","bar_next.php?id=URL VALUES GO HERE",false);

Thanks.

Alright, so I've been writing a plain javascript file, which is called by HTML later to grab information from a certain page and then parse through that information. This is being done as a Windows Gadget, so the "browser" is IE.

I have two main problems with this: One is caching. I can't get not caching to work at all. I've tried headers and I've tried putting something random at the end of the URL. The randomness at the end of the URL works when done from an HTML file embedded with Javascript but will not work from a pure Javascript file.

My other, potentially bigger, problem is that the xmlhttp object does not seem to ever want to open again. I'm pretty sure what's happening is it doesn't get back into ready state 4. That is, unless I run an html file that accesses the same url. Then, suddenly, the gadget runs its update function and it actually decides to work. The gadget still runs the update function otherwise but it doesn't actually do anything, which is I believe caused by it never getting back to ready state 4 on its own.

I appreciate any help on this, and if I didn't explain anything clearly I'm more than happy to clarify.

Cheers.

Hi,

I am trying to make a fuinction that, when called, will return the string that is retrned in text form from my php code.

This is what i currently have, but it is just failing when it is run, what am i doing wrong?

Code:

function shortenUrl(url) {
 	var response;
	var	xmlhttp = new XMLHttpRequest();
	xmlhttp.open("GET", "http://10.1.1.10/projects/short/?ext&url=" + encodeURIComponent(url), false);
	xmlhttp.send(null);
	xmlhttp.onload = function() {
		var response = xmlhttp.responseText;
		return response;
	}
	return "Failed!";
}

alert(shortenUrl("http://www.google.com.au/"));

Thanks

Edit:

ohh, and this is running chrome, so no standards issues

I am trying to figure out that if the function "xmlhttp.onreadystatechange=function()" returns true the whole function "function checkUser(str)" should return true as well....so not sure how to do it. i have banged my head since long so please advise!

Here is the code below:

--------------------------------------------------------



function checkUser(str)
{
var sp = document.getElementById("msgs");

if (str=="")
{
document.getElementById("msgs").innerHTML="Username cannot be empty.";
return false;
}

if (str.length <= 6)
{
document.getElementById("msgs").innerHTML="Username cannot be less than 6 characters and must not start with a number or a special value";
return false;
}


if (window.XMLHttpRequest)
{ //code for IE7+, firefox, chrome, opera, safari
xmlhttp=new XMLHttpRequest();
}
else
{ //code for old IE
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}

xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
if (xmlhttp.responseText === 'FOUND')
{
sp.style.color = "red";
sp.innerHTML = "[ERROR]: The username \"" + str + "\" already exist. Please try a different name.";
return false;
}

else if (xmlhttp.responseText === 'NOT FOUND')
{
sp.style.color = "blue";
sp.innerHTML = "Username: VALID";
return true;
}

}
}

xmlhttp.open("GET", "checkUser.php?q="+str,true);
xmlhttp.send();

}
