JavaScript - Append String To Referring Url

hello,

I'm trying to build a simple function to append and replace an argument in a query string,

for example, if my url was like;

www.domain.com/page.php?test=123&blah=abc

and I want to add on qty=5 like;

www.domain.com/page.php?test=123&blah=abc&qty=5

ok, no problem there, however if I now want to update that to qty=6, i get this:

http://www.domain.com/page.php?test=...bc&qty=5&qty=6


my code thus far;
Code:

function AppendURL(){
	var AURL = document.getElementById('AddToCartLink');
	var numQty = document.getElementById('Qty').value;
	var TempURL = AURL.href;
	AURL.href = TempURL + '&Qty=' + numQty;
}

The code is JScript .NET, which is basically a .NET version of Javascript. Regardless of language, Anyone with appending type of skill can answer my question.

The problem is, when I keep issuing the request it keeps appending over and over again



Code:

if (oSession.uriContains("search?q=")) 
{
    var str = oSession.fullUrl;
    var sAppend = "+test1+test2+test3";
    if (!oSession.uriContains(sAppend))
    {
        oSession.fullUrl = str.replace( "search?q=","search?q="+sAppend);
    }
}

Can you please give me an example? I'm still new to programming.

Thank you

In this case, Let's take Google Search as example:

The code is JScript .NET, which is basically a .NET version of Javascript. Regardless of language, Anyone with appending type of skill can answer my question.

This code is used in Fiddler(It's a Man-in-the-middle proxy)

Code:

if (oSession.uriContains("&q=")) // oSession is a Fiddler object session // uriContains() function, checks for case-insensitive string from the URI
{
    var str = oSession.fullUrl;
    var sAppend = "test1+test2+test3";
    if (!oSession.uriContains(sAppend))
    {
        oSession.fullUrl = str.replace( "&q=","&q="+sAppend);
    }
}

For those who are confused, It says, If &q= is present in the URI, replace/append &q= with &q=test1+test2+test3

Problem: It appends test1+test2+test3 instantly, when it sees &q= in the URL.

Basically, how do I make it wait until I click the submit/search button

Thank you.

Update: I heard about Onsubmit() event, but not really familiar with it. How do I use it? like, should I go to google source page and edit the form id?

Also, Any other methods besides Onsubmit()?

I am using a third party shopping cart service written in php. I don't have access to the php code so I decided to use javascript to write a cookie.

What I'm trying to do is have the cookie capture the referring URL and then keep it for a day and have it follow where ever the visitor goes in the shopping cart. Then when they check out, the referring URL will populate a form field and be returned as part of the form results. This way I can track where my visitors come from. My code is below and I'm adding it to the file designated as the head section. (The files I have access to must use some form of include but I can't use php in them - just html and javascript. I've tried.)

I have an alert in the code that suggests something to do as well as set the cookie. The alert comes up and the cookie is set but when you go to another page, the alert comes up again and another cookie is set. I just need to have it set once so when they fill out the order form, I'll know where they came from.

This is my code and thanks for the help.

Code:

<SCRIPT LANGUAGE="JavaScript">
cookie_name = "dataCookie";
var referred;
function getName() {
if(document.cookie)
{
index = document.cookie.indexOf(cookie_name);
if (index != -1)
{
namestart = (document.cookie.indexOf("=", index) + 1);
nameend = document.cookie.indexOf(";", index);
if (nameend == -1) {nameend = document.cookie.length;}
referred = document.cookie.substring(namestart, nameend);
return referred;
}
}
}
referred=getName();
if (referred == "dataCookie")
{referred = "No-Referral"}
function getCookie(c_name) {
		if (document.cookie.length>0) {
			 c_start=document.cookie.indexOf(c_name + "=")
			 if (c_start!=-1) {
    		c_start=c_start + c_name.length+1 
    		c_end=document.cookie.indexOf(";",c_start)
    		if (c_end==-1) c_end=document.cookie.length
    				return unescape(document.cookie.substring(c_start,c_end))
      } 
  		}
		return ""
}	
function setCookie(c_name,value,expiredays) {
		var exdate=new Date()
		exdate.setDate(exdate.getDate()+expiredays)
		document.cookie=c_name+ "=" + escape(value) + ((expiredays==null) ? "" : "; expires="+exdate.toGMTString())
}		
function checkCookie() 
{
	{
	var cookieEnabled=(navigator.cookieenabled)? true : false 
	//if not IE4+ nor NS6+ 
	if (typeof navigator.cookieenabled=="undefined" &&!cookieEnabled)

		cookieEnabled=(document.cookie.indexOf("testcookie")!=-1)? true : false

							}
							}

						{setCookie('thedate', thedate, 365)}
						alert('Be sure to subscribe to our newsletter.')
    					}
  				}

Hi,

I'm a retired social worker with beginner skills in scripting a web page and need some suggestions.

I create eLearning materials which are given away as a communty service to help people improve their health. A typical eLearning project has a few educational screens (using a Learner Management System-LMS-template) and an interactive exercise (on an external web page-htm or html-usually accessed by button which navigates to the exercise's URL).

The interactive exercise should only be accessed from inside the eLearning lesson using the button, because it requires understanding of the way it works plus important cautions to assure proper use. I need to prevent the use of the URL outside of taking the lesson (for example, someone taking the lesson acquires the exercise's URL from their browser history and then may give this to others who access the exercise directly-without necessary knowledge and cautions).

I tried document.referrer, using JavaScript. Using the referrer URL from inside the lesson and adding the JavaScript to the exercise's htm code worked OK in FF, but not in IE 8. In FF, if the referrer was not the correct single URL from inside the lesson, then it redirected; if the correct URL, the exercise appears.

The JS code follows:

Code:

<script language="JavaScript" type="text/javascript">
<!--
var oksite = "http://www.mysite.com/xyz/courseidxxxxx/yyyy/zzz.html";
var redirect = "http://mysite.com/error.html"; 
if (document.referrer != oksite)
{
location.replace(redirect);
}
//-->
</script>

In IE 8, I was not able to get it to work. Using an alert, I noticed that the referrer in IE 8 was blank.

My web hosting (GoDaddy) is a shared Windows hosting. I would have to upgrade from IIS6 to IIS7 to use PHP. Bigger challenge: I've never used PHP. If possible, I would prefer to use JS. But, I am open to any suggestion that will help.

I am also wondering if part of the IE 8 issue is that I am using IE 8 X 64?

I'm stuck and hope someone can suggest a way to solve this access issue.

Thanks for your help.

Kind Regards,
