The Document Object Model (DOM) as implemented in MSXML provides a programmatic representation of XML documents, fragments, nodes, or node-sets. It also provides an application programming interface for working with XML data.
The following JScript fragments outline the basic process of programming with XML DOM.
var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
Example:
function loadXML(xmlFilePath) { try //Internet Explorer { xmlDoc=new ActiveXObject("Microsoft.XMLDOM"); } catch(e) { try //Firefox, Mozilla, Opera, etc. { xmlDoc=document.implementation.createDocument("","",null); } catch(e) { alert(e.message) } } try { xmlDoc.async=false; xmlDoc.load(xmlFilePath); // xmlFilePath - xml file path Ex: test.xml return(xmlDoc); } catch(e) { alert(e.message) } return(null); }

The setInterval() method evaluates a function or an expression repeatedly for the specified number of milliseconds and it returns an interval reference.
Syntax:
variable = setInterval(expression, milliseconds)
or
variable = setInterval(function, milliseconds)
variable holds the interval reference returned by seInterval method.
Example:
Below example display the current time information using setInterval method call the date object.
<html> <head> <title> setInterval Method Example </title> <script language="javascript"> function startSetInt() { ref=setInterval("init()",100); } function init() { dt = new Date(); document.getElementById("lbl").innerText = "Timer : " + dt; document.getElementById("btnStart").disabled = true; document.getElementById("btnStop").disabled = false; } function stopSetInt() { clearInterval(ref) document.getElementById("lbl").innerText = "Timer : "; document.getElementById("btnStart").disabled = false; document.getElementById("btnStop").disabled = true; } </script> </head> <body onload="startSetInt()"> <label id="lbl" name="lbl"></label> </br> </br> <input type="button" id="btnStart" value="Start" onclick="startSetInt()" /> <input type="button" id="btnStop" value="Stop" onclick="stopSetInt()" /> </body> </html>

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition – December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others.

Split Function: Delimiter :-
The space character ” ” we mentioned will be our delimiter and it is used by the split function as a way of breaking up the string. Every time it sees the delimiter we specified, it will create a new element in an array. The first argument of the split function is the delimiter.
Split() Function:-
The split() function splits text and puts the pieces into an array, with each piece taking up one slot in the array. For example, if you were to split “This is some text”,the split() function would create an array with four slots (zero to 3). The first slot in the array would contain “This”, the second slot would contain “is”, the third “some” and the fourth “text”.
Example:-
var stringdata= "1$2$3$4"; var splitdata = stringdata.split("$"); for(i = 0; i < splitdata.length; i++) { document.write("Element " + i + " = " + splitdata [i]); }
Output
=====
Element 0 = 1
Element 1 = 2
Element 2 = 3
Element 3 = 4

Example:-
Display Next Day of Today
function getNextDate() { var date= new Date(); var day = date.getDate(); var month = date.getMonth(); var year = date.getYear(); var nextdate= new Date(year, month, day +1); var nxtDate=nextdate.getMonth()+1+"/"+nextdate.getDate()+"/"+NextDate.getYear(); document.getElementById('DisplaynextDate').value=nxtDate; //Display Next Date(today+1) }

var cell2 = row.insertCell(1); var txt = document.createElement('input'); txt.setAttribute('type', 'text'); txt.setAttribute('name', 'firsttextbox'); txt.setAttribute('className', 'text_box'); txt.setAttribute('id', 'firsttextbox' + iteration); txt.setAttribute('size', '21'); cell2.appendChild(txt);
3.If u Add a Textarea to a Table,then use this
cell1 = row.insertCell(1); var e1 = document.createElement('textarea'); e1.name = 'text2' + iteration; e1.id = 'text2' + iteration; e1.column= '50'; cell1.appendChild(e1);
4.Row can be Re-Order by using
var tbl = delRow.parentNode.parentNode; tbl.tBodies[0].rows[i].myRow.two.id = 'firsttextbox' + count;
If u Delete 3 Row the Reorder as
4th Row as—-3th Row
5th Row as—-4th Row
6th Row as—-5th Row
5.If u want to Delete the Third Row,then use this coding
var delRow = obj.parentNode.parentNode; var rowArray = new Array(delRow); for (var i=0; i<rowObjArray.length; i++)</div> { var rIndex = rowObjArray[i].sectionRowIndex; rowObjArray[i].parentNode.deleteRow(rIndex); }
