copied!<p>Several ways to accomplish this. Like above, look at the .NET PageMethod/WebMethods. It will show you how to build the WebMethods and call them from Javascript.</p> <p>I've been switching away from .NET pre-built stuff and going with straight jQuery ajax calls. It's the same thing, but using jQuery you have a little more control over the call and what it returns.</p> <pre><code>jQuery.ajax({ type: "POST", url: "edit.aspx/yourmethodname", data: "{yourmethodparam:" + somevar + "}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(response) { alert(response.d); } error: function(err, response) { alert("error"); } }); </code></pre> <p>It's more complex, but you get more control over what type of object is returned, JSON or text. </p> <p>Remember, response.d the "d" is the JSON object if you decide to return more then just a simple type, like string or integer. You can return objects like lists and such. These will be converted to JSON objects. If it were a simple type like an integer, then just 'response' would be the value.</p> <p>If you decide to go more complex and use JSON return objects, watch the 'datatype' property, sometimes I found .NET returning string objects that had to be converted into JSON using, json2.js file - <a href="http://www.json.org/js.html" rel="nofollow noreferrer">http://www.json.org/js.html</a>. It threw me for a loop for a long time. It's a good site that will explain JSON, as that's what the PageMethod/WebMethods are really using.</p>
