Colleagues asked me, we get data from the database, the Ajax way to display the front page. Don't say anything, write a case.

1, create a page:

<!DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "Http://www.w3.org/TR/html4/loose.dtd "><HTML><Head> 　　 <Scripttype= "Text/javascript"src= "Ajax.js"></Script> 　　 <Metahttp-equiv= "Content-type"content= "text/html; charset=utf-8"> 　　 <title>Ajax Demo</title></Head><Body> 　　 <inputtype= "button"ID= "Txt1"onclick= "Showhint ()"value= "Get 123"/> 　　 <P>Digital:<spanID= "Txthint"></span></P> </Body></HTML>

2. Write a JS, which is Ajax

1 varXMLHTTP;2 functionShowhint ()3 {4     //defining a new array5     varArray =NewArray ();6     //Create a XMLHttpRequest object7     if(window. XMLHttpRequest)8{//code for ie7+, Firefox, Chrome, Opera, Safari modern browser9xmlhttp=NewXMLHttpRequest ();Ten     } One     Else A{//code for IE6, IE5 user low version IE -xmlhttp=NewActiveXObject ("Microsoft.XMLHTTP"); -     } the      -     //set the request type, request address, and whether to enable asynchronous processing requests, most settings turn on True -Xmlhttp.open ("GET", "gethint.php",true); -     //sending requests to the server + xmlhttp.send (); -     //Handling onReadyStateChange Events We specify the tasks that are performed when the server responds to readiness to be processed +Xmlhttp.onreadystatechange=function() A     { at         if(Xmlhttp.readystate==4 && xmlhttp.status==200) -         { -document.getElementById ("Txthint"). innerhtml=Xmlhttp.responsetext; -         } -     } -}

3, OK, write a PHP bar, as a server. The data is false.

1<?PHP2 //populate an array with a name3 $a[]= "1";4 $a[]= "2";5 $a[]= "3";6 7 $hint="";8  for($i= 0;$i<Count($a);$i++)9 {    Ten     $hint=$hint."  ".$a[$i]; One } A $response=$hint; - //Output Response - Echo $response; the?>

Look at the interface:

Click the button:

No more than a few more, come out.
