Question

I want to pass the value entered by a user in a form field from a page called “productDetail” to the form field in a page called “gmap-3”.

Now normally, if both fields were on the same page, I’d just do something like :

$('#productDetail').live("pagecreate", function() {
    $('#submitPost').tap(function() {
        if ($('#postalFrom').val()== "" || null) {
            var postalCode = $('#postalFrom').val();
            alert("Enter postal code first.");
        } else {
            $('#from').val(postalCode);
        }
    });
});

But considering the form field “(‘#from’)” is on the page “g-map3” and not “productDetails”, how can I accomplish that ?

Thanks in advance !

Answer 1

when going from one page to another, pass the values with the url e.g.

http://example.com?postalCode=11204&fname=john&lname=doe

then parse the url with location.search. something like

var params = location.search.substring(1,location.search.length).split("&");
for (var i = 0; i < params.length; i++)
{
  var field = params[i].split("=")[0];
  var value = params[i].split("=")[1];
  // process
}

EDIT

forgot to get rid of the “?” 😛 hence the substring(1,location.search.length)
