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 i         


        

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();

Answer 2

In my experience

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

is good on a browser running on a PC. But on mobile if you want the keyboard to show up so the user can input directly then you also need:

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