dom events - How to set cursor to input box in Javascript?

Question

document.getElementById(frmObj.id).value="";
document.getElementById(frmObj.id).autofocus;
document.getElementById("errorMsg").innerHTML = "Only numeric value is allowed";

In the above code the value of the form object is perfectly setting to "" but there is no cursor in the text box. I want a cursor to be there. focus() only focuses that input box but does not actually set the cursor.

Answer 1

In JavaScript first focus on the control and then select the control to display the cursor on texbox...

document.getElementById(frmObj.id).focus();
document.getElementById(frmObj.id).select();

or by using jQuery

$("#textboxID").focus();
