Updating web pages with ajax
Other differences between Java Script objects and JSON include support for data types: JSON does not yet have an accepted standard for representing datetimes, for example. NET application, the raw content of that request populates the , which states that I am expecting the "Receiver" page to return some HMTL to me.
If all goes well with the request, the returned HTML will be plugged in to an element with the id of "result".
And this time, the response shows that the Rsequest.
Input Stream is the only place where I can get at the posted data on the server.
As I touched on earlier, there is nothing magical about JSON.
It is just a data interchange format where values are converted to a string.
However, most issues that I have seen relating to j Query POST requests seem to result from a lack of understanding about how these settings actually work.
You can post a range of different data types including form values, arrays, Java Script objects and JSON.
However, its server-side processing model has several drawbacks inherent in the technology: Enter Microsoft's ASP. AJAX, which stands for A synchronous J ava Script A nd X ML, is an integrated framework for providing incremental page updates via cross-platform Java Script, composed of server-side code comprising the Microsoft AJAX Framework, and a script component called the Microsoft AJAX Script Library. NET AJAX extensions also provide cross-platform support for accessing ASP. This whitepaper examines the partial page updates functionality of the ASP.NET Razor Web Pages and explores how different options have different results.This information is provided at the j Query site ( Query.ajax/) and what is detailed above doesn't add to the official documentation.The demo displays the latest blog posts from the rss feed on my blog and displays the date and time for the latest data refresh.
I’ve also hooked up a loading image for the AJAX requests using $Setup() but this is optional if you didn’t want to see a loading image you could remove this code or even display a smaller loading image so the data is still visible on screen while the new data is loading asynchronously.
The result from posting the car object looks like this: So if you want to post a Java Script object via j Query, pass the plain object to the option alone. Then you can access the property values of the object in the Request collection as if you have posted a form.
