Another simple Javascript question..sending a variable from a link to a .js file

[Syringer]

So I have a .js file that I want to run with a variable in it--and what I have is basically:

http://blah.com/a.js&id=100

and within a.js I have:

window.open('http://wharg.com/blah.jsp?seller='%id, 'var_here, features);

but that doesn't work.

You need a server side language to pick up that arg and render it into the javascript.

you can get the url params in javascript, but from what i remember you have to parse the url manually (or at least methodically)

 

[Snapster]

You can get the param using a parser function like:

function QueryStringParam( name )
{
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var tmpURL = window.location.href;
var results = regex.exec( tmpURL );

if( results == null )
{
return "";
}
else
{
return results[1];
}
}

So:

window.open('http://wharg.com/blah.jsp?seller=' + QueryStringParam('id'), features);

Well, just like with the other question, there are some misconceptions here too 🙂
You can not have a hyperlink to a .js file. If you do, the browser will prompt your user to either open or save the file to their computer. JS files are not associated with web browsers. On windows computers, for example, they are associated with wshost (Windows Script Host). Even if the user chooses to open the file from the browser, it would still first launch the script host and then run your file, which is, I am sure, not something you were planning on. Tell us what your scenario is and what are trying to achieve.
