Javascript Object

1.ArraYObj = {}; =>In javascript this way we can define an array obj

2.ArrayObj = new Array();

obj = function(){}=>This way we can define a function and here the function behave as object

Note:1.An element's offsetLeft and offsetTop properties return the pixel distance the element is offset from its offsetParent.The main offsetParent is body but

<td> <img id="TheWRImage" src="wrlogo.gif" /> </td>

In the above ex referenc to the image id offset parent is <td>

After creating a event object in the following way we can call a function at the time of fire an event.

eventobj = document.getElementById('testeventid');

eventobj["onclick"] = function() { alert("ok");};

eventobj["onmouseover"] = function() { alert("bk");};

Singletone javascript function

testFunction = function() { this.value1 = "testvalue"; } testFunction.prototype.test = function() { alert(this.value1); } eventobj["onclick"] = function() { testobj = new testFunction(); testobj.test(); };

In Javascript we can alocate a value into a member of an object and simultaneously call a function like the following way
testFunction().value2 = "test";
