Regex using groups in javascript

Convert the xml to uppercase except text or textContent and attribute values.

var XML_String="<start_tag><data>some data</data><data id=\"xyz\" id2=\"yyy\">some data2</data></start_tag>"  
XML_String=XML_String.replace(/(<|<\/)([\"_a-zA-Z0-9\s=]*)(>)/gi, function(s, group1, group2,group3) { 
 if(group2.indexOf("\"")>-1){
  var substr=group2;
  substr=substr.replace(/([a-zA-Z0-9=_\s]*)(\")([_a-zA-Z0-9]*)(\")/gi,function(sb,group1,group2,group3,group4){
   return group1.toUpperCase()+group2+group3+group4;
  });
  group2=substr;   
 }else{
  group2=group2.toUpperCase()
 }   
return group1+group2+group3;});

Add CDATA in JavaScript

 var newCdata=dataXmlDom.createCDATASection("data to append");  
 newContextElem.appendChild(newCdata);  

XSLT on Client

 function xmlTranform(){  
      var xml=file.xml;  
      var xsl=file.xsl;  
      if(window.ActiveXObject)   
      {  
           ex=xml.transformNode(xsl);  
           jDivObj.append(ex);  
      }else if(document.implementation && document.implementation.createDocument){  
           var xsltProcessor=new XSLTProcessor();  
           xsltProcessor.importStylesheet(xsl);  
           var resultDocument=xsltProcessor.transformToFragment(xml,document);  
           var i=resultDocument.firstChild.innerHTML;  
           $("#testDiv").html(i);                                 
      }  
      tb_show("xslt", "#TB_inline?&height=485&width=750&inlineId=testDiv","");// thickbox overlay  
      $("#testDiv").empty();  
 }  

RegExp in JavaScript

 <script type="text/javascript">  
 var str = "mastertablemastertext";  
 var patt1 = /master/i;  
//i is modifier for case-insensitive and g for Global search
 alert(str.match(patt1));  
 </script>  

Arrays in Javascript

 function start() {  
      var example=new Array();  
      example[0]="first";  
      example[1]="esc";  
      for(var i=0;i<example.length;i++){  
           alert(example[i]);  
      }  
      example[example.length]="third";  
      alert(example.length+" "+example["esc"]);  
 }

Pop-ups

 function post_to_url(path, params, method) {  
      method = method || "post"; // Set method to post by default, if not specified.  
      //Here we are creating a form tag and adding attributes to it   
      var form = document.createElement("form");  
      form.setAttribute("method", method);  
      form.setAttribute("action", path);  
      form.setAttribute("target", "NameofthePopup");   
      //Creating input tag and adding attributes to it  
      for(var key in params) {  
           var hiddenField = document.createElement("input");  
           hiddenField.setAttribute("type", "hidden");  
           hiddenField.setAttribute("name", key);  
           hiddenField.setAttribute("value", params[key]);  
           //adding input tags to from tag.  
           form.appendChild(hiddenField);  
      }  
      document.body.appendChild(form);  // Not entirely sure if this is necessary  
      window.open('URL',"NameofthePopup","width=670,height=680,toolbar=no,location=no,directories=no,status=no,menubar=no,resizable=no");  
      form.submit();// submitting the form  
 }  

• In the above function we are using the Post method to send the parameters.
• params should be in follwoing formate(inside the flower brackets):{Arg1:'Arg1Value',Arg2:'Arg2Value'} 

Char to ascii in javascript

 function ascii_value (c)  
 {  
      // restrict input to a single character  
      c = c . charAt (0);  
      // loop through all possible ASCII values  
      var i;  
      for (i = 0; i < 256; ++ i)  
      {  
           // convert i into a 2-digit hex string  
           var h = i . toString (16);  
           if (h . length == 1)  
                h = "0" + h;  
           // insert a % character into the string  
           h = "%" + h;  
           // determine the character represented by the escape code  
           h = unescape (h);  
           // if the characters match, we've found the ASCII value  
           if (h == c)  
                break;  
      }  
      return i;  
 }
