[Original] PHP+ajax implements simulated Win file management system 8_PHP tutorial

I have been quite busy during this period, so I took some time off to finish it. Now I will continue to talk about the js.js file renaming function

function edit(e,path){

var text=e.innerHTML;

var eT=document.createElement("input");//The file name is rewritten according to the user's click

e.innerHTML="";

e.appendChild(eT);

eT.value=text;

eT.select();

e.onclick="";

eT.onblur=function(){                                      

CreateAjax();

if(text == this.value){

e.innerHTML=this.value;

e.onclick=function(){edit(this,path)};

Return false;

}else{

e.innerHTML=this.value;

Re_name(path,this.value,e);

e.onclick=function(){edit(this,path)};

}

};

}

The above is DOM+JS to complete and operate the file.

function CreateAjax(){//I won’t say much about this function, it has been discussed many times.

try { xmlhttp = new XMLHttpRequest();}

catch (e){

try { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");}

catch (e2){

try { xmlhttp = new ActiveXObject("MSXML2.XMLHTTP"); }

catch(e3){ xmlhttp = false; }

}

}                                           

if( !xmlhttp){alert('Sorry, the browser you are using does not support AJAX!'); return false;}

}

function Re_name(o_name,n_name,e){ //Renamed here.

var name=o_name.replace(/.*/(.+)$/i,"$1");

if(name.match(/^w{1,255}.w{1,8}$/i)){//Use regular rules to determine the legality of the file name.

if(!n_name.match(/^w{1,250}.w{1,8}$/i)){

 

e.innerHTML=name;

document.getElementById("t").innerHTML="

Sorry, the file extension cannot be modified...

";

                                   

setInterval("func()",3000);
       
Return false;

}

}else if(name.match(/^w{1,255}$/i)){

if(!n_name.match(/^w{1,250}$/i)){

e.innerHTML=name;

       

document.getElementById("t").innerHTML="

";

setInterval("func()",3000);

Return false;

}

}else{

​​​alert('illegal operation');

e.innerHTML=name;

return false;

}

var url="rename.php?path="+encodeURI(o_name.replace("/","/"))+"&nname="+encodeURI(n_name)+"&rd="+Math.random();

Senddata('GET',url,ReturnValue,null); //Send to rename.php

}
