I'd like to use a function to "build" the parameters I want to send along a $.post

Something like this :

function makePostParm()
{
var t = '';
var parms = array("id","name");
var vals = array(100,"mark");
for(t=0;t<parms.length;t++){
   t = t + "," + parms[t] + ":" + vals[t];
}
}

function mypost(params)
{
   $.post("ajax.php", {params} );
}

var parameter = makePostParm();
mypost( parameter );

Is this at all possible or ??

Thx,
Mark

You should build an actual object, and not a string representation of it. You can do this through a function, or by explicitly setting them using json notation:

var params = {
    id:100,
    name:"mark"
}

$.post("ajax.php", params);

------
OR
------

function addParam(obj, key, value) {
    obj[key] = value;
}

var params = {};
addParam(params, "id", 100);
addParam(params, "name", "mark");

}

$.post("ajax.php", params);

oops. left an extra "}" there at the end, right before the $.post call. That shouldn't be there!

I made some minor changes - the function should return obj and the obj should be updated like this :

function addParams(obj,key,value)
{
obj[key] = value;
return obj;
}
var params = {};
params = addParams(params,"id",100);
etc.

At least that was what worked for me
