script flexibility

[HaLo2FrEeEk]

Is there any way to pass post variables to a Javascript without explicitly setting them as a parameter in the function name?  For example, in AJAX, if I wanted to pass different url's with different parameters (like, page1 would have user_id, and count passed to it; page2 would have just a url passed to it) without making the javascript function look like this:

 

function dosomething(url, param1, param2, param3) {

  // blah...

  }

 

Could I just make the Javascript get whatever is in the form, no matter what or how many things are in it?

 

Does this make sense?

you could pass an array... you would just have to have PHP format the POST array into something javascript can understand

How would I go about doing that?  Also, I saw a script that passed the form name as a getElementById variable, like:

 

javascript:somefunction(document.getElementById(this.form));

 

I don't know how exactly that worked, but.  Any more help would be really nice.

bump.

you can also directly echo in variables into the raw js on page loads

It's AJAX though, so I can't do that, I need to have different parameters passed to the javascript, the closest I've gotten is this:

 

function ajax(url, div_id, param1, param2, elementname, element) {
  var poststr = param1+((param2 == null || param2 == '') ? "" : "&"+param2)+((element == null || element == '') ? "" : "&"+elementname+"="+document.getElementById(element).value);
  //alert(poststr);
  obj = document.getElementById(div_id);
  loading();
  makePOSTRequest(url, poststr);
  }

 

But that has it's flaws.
