Question

I have simple script which contains two pages – script.php and function.php. Script.php contains one input field with ID #code , one link with ID #submit and jquery function

$('#submit').click(function () {
    $.ajax({
    url: 'function.php',
    type: "POST",
    data: "text=" + $("#code").val(),
    dataType: 'text',
    success: function(data) {
        $('#info').html(data);              
            }
        });         
    return false;
    });

How can I clear #code input field value depending on the return result from function.php?
For example, if query is incomplete function.php will only show message in #info field, but if query is complete script will show message and clear input field value.

Answer 1

Consider returning JSON data from function.php, so something like this

{"clearCode":"true","info":"Some HTML"}

Then you can use the jQuery function getJSON.

This means you can return a boolean which decides whether to clear #code or not and also return some html for #info
