The first reg.php file is done and I'm going to do the second step.

var xmlHttp = false;
function Ajaxcreate () {//Here is the creation of XMLHTTPT to like

try {
XmlHttp = new ActiveXObject ("Msxml2.xmlhttp");
catch (e) {

try {
XmlHttp = new ActiveXObject ("Microsoft.XMLHTTP");
} catch (E2) {

XmlHttp = false;
}

}

if (!xmlhttp && typeof XMLHttpRequest!= \\\ ' undefined\\\ ') {

XmlHttp = new XMLHttpRequest ();

}

if (!xmlhttp) {alert (\\\ ' Create xmlHttp Fail \\\ '); return false;}

}

function Ajax () {//Here is the action to be performed after the reg.php onblur () event is received.

Ajaxcreate ();

var Xmvalue=document.getelementbyid ("XM"). Value;

var url= "/boke/blog/type.php?txt=" +encodeuri (Xmvalue);

if (xmvalue== null | | xmvalue.length>20 | | | xmvalue = "") return false;

Xmlhttp.open ("POST", url,true);

Xmlhttp.setrequestheader ("Content-type", "application/x-www-form-urlencoded");

Xmlhttp.send (Xmvalue);

Xmlhttp.onreadystatechange=returnstate;

}

function Returnstate () {

if (xmlhttp.readystate!= 4) {

document.getElementById ("Divxm"). Innerhtml= "<div id=\\\ ' phperblog_showinfo_red\\\ ' ><font color=red> In the verification, please ...</font></div> later ";

}

if (xmlhttp.readystate = = 4) {

document.getElementById ("Divxm"). Innerhtml=xmlhttp.responsetext;

}

}
