JS Code:     Some HTML code: & Lt; TD width = "387" align = "Left" & gt;Onchange = "getcity (this. Options [This. Options. selectedindex]. Value);">Province Pr = NULL;For (INT I = 0; I PR = (province) allpros. Get (I );%>">}%>& Lt; TD width = "387"

  Page for implementation: drag the DIV & Lt; TD width = "25%" valgin = "TOP" & gt; Ajax DataGrid Asp.net & Lt; TD width = "25%" & gt; C #. Net & Lt; TD width = "25%" & gt; expose Crip Js xmlhttp. js called on the page // JavaScript

Now, more and more Ajax applications are used. The company found some materials on the Internet so that they can be used in the future, however, I have not found any examples in development. Now I have posted a simple example for your reference. I

One of the ways to submit a form using Ajax is to convert the form data into a string of request strings. Below is Convert form data into a string of request strings Function formtorequeststring (form_obj){VaR QUERY_STRING = '';VaR and = '';//

Finally, it's a good time. An example of Ajax partial Refresh: Front-end page:   Ajax partial refresh   Background page: [getpart. asp]   Dim rs Dim SQL Set rs = server. Createobject ("ADODB. recordset ") SQL = "select * From king_test"

// Ajax application // My God, I cannot understand PHP. Forget it. Find an example of Asp.net. /* Use jquery to generate a div container with the ID "rating ". The Code generates five links and appends them to the "rating" container. When one of

There are many messy solutions on the Internet, such as setting up Web. config. Thanks to the monkey for telling me the most common method is the front-end JS Chinese code escape () and backend decoding server. urldecode () In addition, if the

Today I have nothing to worry about. in C #2.0, I used ajax to write an example of refreshing and fast paging. The time is too short. For the shortcomings, please point out that we should first put ajaxpro. DLL file to reference, you can go to http:/

Originally, when I wrote Ajax in vs2003, I referenced Ajax. dll. Today I used vs2005 to find that this Ajax cannot be used. In the previous call dialog box, "jscript runtime error: the object is missing", so I found an ajaxpro.2.dll to reference it.

If you do not use any help package, you may write a large amount of code to create an XMLHTTPRequest object and asynchronously track its process, then parse the response and process it. You are very lucky when you do not need to support more than

var xmlhttpreq; // create the XMLHTTPRequest object function createxmlhttprequest () {If (window. XMLHttpRequest) {// Mozilla xmlhttpreq = new XMLHttpRequest ();} else if (window. activexobject) {// IE browser try {xmlhttpreq = new activexobject

Ajax is usually used for asynchronous processing, but in some cases, Ajax synchronization is used to process data. For example, when detecting data with JS, Ajax is required to submit a request to obtain whether the user exists in the database, this
