I was having problems with putting web2py tags inside my util.js, so I
moved it to the views instead:
function doPost(callback, data) {
$.post(callback, data, function(data){})
.done(function() { alert("Done!"); })
.fail(function() { alert("Failed!");})
}
function add_item(url, item_id, some_detail) {
var test = {};
test.item_id = item_id;
test.some_detail = some_detail;
var dat = {'test' : test};
var data = $.toJSON(dat);
doPost(url, data);
}
My button looks like this now:
<a href="" id="additem" onclick="add_item({{=URL('default', 'add_item')}},
{{item.id}}, 1);">Add Me</a>
But for some reason the add_item() in util.js is not being called.
