    Which is a good approach?

    Hi. I want to call 2 functions on body load.(JS functions).

    So calling both on body load is good or call one function on body load and call other one at the end of first function?

    i mean;

    Code:
    function my fun()
{

}

function myfun2()
{


}
<body onLoad="myfun();myfun2()">
    or

    Code:
    fuction myfun()
{


// Do all craps here.


myfun2();
}

function myfun2()
{


// Do all craps here.

}

<body onLoad="myfun()">
    Which approach is good.

    Is there any advantage and disadvantage in both of these?

    Regards

      that depends a bit on the 'craps' that should be done ... seen from a practical usage ... you could even use:

      Code:
      function initPage() {
    myFun1();
    myFun2();
}
      and later on:

      Code:
      <body onload="initPage();">
      which is a bit better since usally the scripts are in external files and it is good practice to have single entry and return points in your code ... but its even a bit of taste of the programmer ... i would use the method shown above ... since i think the methods typically should be self contained and in html there should only be one call ... so that i could have a look at the js-file and see what happens when initPage() is called ... i wouldn't destroy the 'semantics' of myFun1() with the call of the second function and might be you want to call it alone somewhere ... but when you call myFun2() within it then you need params or whatever to avoid the call of myFun2() sometimes ...

      kind regards

              Ok.. Back to actual problem.

              I want to create few text boxes dynamically and also i want to incorporate auto update via AJAX.

              So i need dynamic text box creation function and auto update function both to be called on body load.

              Regards

                      Not back to actual problem.

                      But back to actual question.

                      The reason why i asked that question

                          I am starting to implement it.

                          If problem arises definitely post question.

                          Regards
