Lost with .net and jQuery

I'm convinced t开发者_如何学运维his has been asked before and have found quite a few resources on this topic but I'm still very confused and not sure how to proceed.

I have a textarea whose data I need to send to a server and I need to capture the result which is a string. Here is my attempt:

$(document).ready(function () {

    $('#output-box').hide();

    $('#form1').submit(function () {
        var input = $('#txtinput').val()
        $.post('Default.aspx', { func: "ParseData" }, function (data) {
            $('#output-box').load(data).fadeIn();
        });
    });
});

How horribly am I off the mark?

Close, but try this:

$(function () {  // I like the shorthand way

    $('#output-box').hide(); 

    $('#form1').submit(function () { 
        var input = $('#txtinput').val();
        $.post('Default.aspx', { func: "ParseData" }, function (data) { 
            $('#output-box').val(data).fadeIn(); // set the value to the returned data 
        });
        return false; // block the normal submit action
    }); 
});

Basically, you use the val() function to change the value of the textarea rather than "loading" data into it. Also, you need to return false from the event handler or you will both send the AJAX request and do the normal, post action on the form.

Edit: based on your comment. If you need to call parseData first, then something like this might be appropriate.

$(function () {

    $('#output-box').hide(); 

    $('#form1').submit(function () { 
        var input = parseData( $('#txtinput').val() );
        $.post('Default.aspx', { txtinput: input }, function (data) { 
            $('#output-box').val(data).fadeIn();
        });
        return false;
    }); 
});
