Nav Send Data To Web Service Javascript
That is a nice solution by Alistair. After studying it a bit (wasn't sure at first too), an object literal is created containing 4 properties. The value of each property (1) is arbitrary. It then sees if the form 'name' exists in the object as a property. That check boils down to:return!objthis.name. Where 'obj' is the object containing the 4 properties. If 'this.name' (e.g.

VIEWSTATE, address, name, etc) is a property within obj, false is returned so the item is filtered out. Likewise, if 'this.name' is not a property of obj, it evaluates to false which returns a true value so the filter function keeps the value. I tried using your code, and was very impressed with the ease it allowed for submitting the form, especially using the ServerProxy script, which will be useful as well in other scenarios calling the ASP.NET server.One issue I have, which is not directly related to this but popped up after using this solution, was the value of the name attribute of the input element. Basically, the input has runat=server and appears inside a content placeholder (and a master page), and the name is now a combination of the naming containers (ex. 'ctl100$ContentPlaceholder1$TextBox1'), which is basically useless when trying to extract the values on the server.
Do you know of any solutions or workarounds for this issue?If you could send any replies to my email address as well, I would really appreciate it (schmuli @ gmail). Great article. I like the way jQuery is used without ScriptManager (sucky ScriptManager). It is native to the browser and JavaScript nature.There is only one problem here, and that is, your server code (Page Method body) is now dependent on the markup, which technically means that whenever you update your markup, you have to update the body of Page Method too.Anyway, let's support CSS3. Have a look at CSS3 Multi-Column Layout Module.Thanks.
In ASP.NET 3.5+, if you decorate your web service class as a ScriptService, then you don't have to do any of that mess. The framework will deserialize form data and try to match to the parameters of the web method.Also, if you decorate the web method as ScriptMethod, you can optionally pass into the ScriptMethodAttribute a named parameter to specify the ResponseFormat as JSON.
Again, the framework will use the JavascriptSerializer to try and convert the method return object into JSON and send it down the pipe to the client.
