Script code to implement UrlEncode and UrlDecode with JavaScript_javascript skills

Copy code The code is as follows:

<script type="text/vbscript">
Function str2asc(strstr) 
str2asc = hex(asc(strstr)) 
End Function 
Function asc2str(ascasc) 
asc2str = chr(ascasc) 
End Function 
</script>

Convert vbscript function into javascript for easy use in non-IE browsers

Copy code The code is as follows:

function str2asc(strstr){
return (" 0" strstr.charCodeAt(0).toString(16)).slice(-2);
}
function asc2str(ascasc){
return String.fromCharCode(ascasc);
}

Copy code The code is as follows:

<script type="text/javascript">
/*The UrlEncode and UrlDecode functions start here*/ 
function UrlEncode(str){ 
var ret=""; 
var strSpecial="!"#$%&'()*, /:;<=>?[]^`{|}~%";
var tt= "";

for(var i=0;i<str.length;i ) {  
 var chr = str.charAt(i);  
 var c=str2asc(chr);  
 tt = chr ":" c "n";  
  if(parseInt("0x" c ) > 0x7f){                                                                         
ret =" ";
else if(strSpecial.indexOf(chr)!=-1)
ret ="%" c.toString(16); t=chr ;  
                                                                                                 .length;i ){ 
 var chr = str.charAt(i); 
 if(chr == " "){ 
 ret =" "; 
 }else if(chr==" %"){ 
 var asc = str.substring(i 1,i 3); 
 if(parseInt("0x" asc)>0x7f){ 
 ret =asc2str(parseInt("0x" asc str.substring(i 4,i 6)));
i =5;
}else{
ret =asc2str(parseInt("0x" asc));
} else{
ret = chr;
}
return ret;
} ert(UrlDecode("����")) ; 
</script>
