Today, let's look at the pagination in silence. Think about it as if no post has been posted in the original area for a long time. Let's extend it to a PHP + AJAX paging demonstration by the way. Okay, let's talk about it, first, we are still the basic AJAX development framework:
Copy content to clipboard
Code:
Var http_request = false;
Function send_request (url) {// initialization, specifying the processing function and sending the request function
Http_request = false;
// Start initializing the XMLHttpRequest object
If (window. XMLHttpRequest) {// Mozilla Browser
Http_request = new XMLHttpRequest ();
If (http_request.overrideMimeType) {// sets the MIME category
Http_request.overrideMimeType ("text/xml ");
}
}
Else if (window. ActiveXObject) {// IE browser
Try {
Http_request = new ActiveXObject ("Msxml2.XMLHttp ");
} Catch (e ){
Try {
Http_request = new ActiveXobject ("Microsoft. XMLHttp ");
} Catch (e ){}
}
}
If (! Http_request) {// exception. An error occurred while creating the object instance.
Window. alert ("An error occurred while creating the XMLHttp object! ");
Return false;
}
Http_request.onreadystatechange = processrequest;
// Determine the request sending method, URL, and whether to execute the following code synchronously
Http_request.open ("GET", url, true );
Http_request.send (null );
}
// Function for processing the returned information
Function processrequest (){
If (http_request.readyState = 4) {// judge the object status
If (http_request.status = 200) {// The message is returned successfully. Start to process the information.
Document. getElementById (reobj). innerHTML = http_request.responseText;
}
Else {// The page is abnormal.
Alert ("the page you requested is abnormal! ");
}
}
}
Function dopage (obj, url ){
Document. getElementById (obj). innerHTML = "reading data ...";
Send_request (url );
Reobj = obj;
}
I put the content in a p display. When the page flip action is generated, I use AJAX to update the DIV to achieve the page flip effect. This is the page code for displaying the content:
Copy content to clipboard
Code:
Header ("Content-type: text/html; charset = GBK"); // output encoding to avoid Chinese garbled characters
?>
