Question

I have some code like:

$.post('/Invoice/UpdateFieldUser/', invoiceLine, function (data) {
    if (data == 'false') {
        alert("An approver could not be updated");
    } else {
        var fieldlabel = $('#fieldapprovallabel' + invoiceLineId + '');
        fieldlabel.text($(".fieldapproverddl option:selected").text());
    }
})

UpdateFieldUser returns a boolean. I thought I could test the return value as above but it isn’t working. Anyone know what I’m doing wrong?

'false' is a non-empty string which evaluates to true. Try using false (no quotes), or use developer tools (like Firebug) to inspect the value of data to see what is actually being returned.
