passing variables in href tag

jordan2000 · 08-08-2012, 04:11 AM

What is the correct syntax for passing variables in a href tag when the href is outside of the javascript tags? I believe it is not recognizing the href because it is not reading the variables: boxid & projectname. Please advise.

*******************************************************

<script type="text/javascript" language="javascript">

var linkURL = '';
var boxid = '';
var changeLinkURL = '';

function getUrlVars()
{
var vars = [], boxid;
var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
vars[key] = value;
});
return vars;
}

function PassQueryString()
{
boxid = getUrlVars()["boxid"];
projectName = getUrlVars()["project"];
alert("ParseQueryString - BoxID :" + boxid);
alert("ParseQueryString - ProjectName :" + projectName);

}
function changeLinkURL()
{
boxid = getUrlVars()["boxid"];
projectName = getUrlVars()["project"];
linkURL = "C:\Users\Geri\Desktop\test_1.htm + "?boxid=" + boxid + "&projectName=" + projectName";
}
function Project(pname)
{
location.href=menuURL[pname];
}

</script>

<script type="text/javascript">
var first = getUrlVars()["boxid"];
var second = getUrlVars()["project"];
alert("back button : " + "" + first);
alert("back button : " + "" + second);
</script>

<a href="C:\Users\Geri\Desktop\test_1.htm?boxid=DBB&project=projectName">

<IMG style="BORDER-BOTTOM: 0px solid;
BORDER-LEFT: 0px solid; BORDER-TOP: 0px solid; BORDER-RIGHT: 0px solid" border=0
alt="Back Button" src="C:\Users\Geri\Desktop\test_1.htm/Back%20Button/back_button1.gif">
</A></P>

</a>

<body>
</body>
</html>

The first problem I see is with the URL itself. I have not had much luck getting Windows-style directories to work well in a browser. Try replacing C:\Users\Geri\Desktop\test_1.htm with file:///Users/Geri/Desktop/test_1.htm*

Second, I notice your quotations are not matched:

linkURL = "C:\Users\Geri\Desktop\test_1.htm + "?boxid=" + boxid + "&projectName=" + projectName"; should be

linkURL = "C:\Users\Geri\Desktop\test_1.htm" + "?boxid=" + boxid + "&projectName=" + projectName"; **

And back to the link itself, you shouldn't use an entity for the "&"

Hope I could help

.
The "getUrlVars()" method you use here would have been helpful to me on my first project, where I had a password protected page (the password was less for actual protection; as my father always says, "locks only keep honest people out"). I ended up needing to set up a localhost server.... backstory over...

*it might be file:///c/....
**You could actually cut that part out, making it linkURL = "C:\Users\Geri\Desktop\test_1.htm?boxid=" + boxid + "&projectName=" + projectName";

passing variables in href tag

We can pass variable using the ? Symbol.
for example :

is we want to send a name and id of a person the we can sent it using the following format.

name = "Minisuit";
Id= 1001;
Now we can send it

<a href =nextpage.html?FirstName=name&id=id >click Me </a>
