I like to use my own code to do that. This is independent of Marketo and should work for any form fields.
I created this function to parse the url and grab any parameters it may have:
function getQueryString( name )
{
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec(window.location.href);
if( results == null )
return "";
else
return results[1];
}
Then I declare a variable for each value I intend to use from the parameters like this:
var firstname = decodeURI(getQueryString('fname')).replace(/\+/g," ");
Since you said that you already have jquery running on the site you dont need to re-declare it. Just use it.
Like this:
var $jQ = jQuery.noConflict();
$jQ(document).ready(function() {
$jQ('#FirstName').attr('value',firstname);
});
If you are trying to pass the values of ...?
fname=John&
lname=Doe to fields called FirstName and LastName respectively on the form, the code would like like this within a script tag.
START sample
////////////////////////////
//This function will parse the URL
function getQueryString( name )
{
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec(window.location.href);
if( results == null )
return "";
else
return results[1];
}
// Declare variables for ease of use later
var firstname = decodeURI(getQueryString('fname')).replace(/\+/g," ");
var lastname = decodeURI(getQueryString('lname')).replace(/\+/g," ");
var $jQ = jQuery.noConflict();
$jQ(document).ready(function() {
// Assign the values to the fields
$jQ('#FirstName').attr('value',firstname);
$jQ('#LastName').attr('value',lastname);
});
////////////////////////////
END sample
I hope that helps.
Good luck!
