How to enable a disabled text field?

Question

I wanna know how do I enable a disabled form text field on submit. Also I wanna make sure if user goes back to form or click reset field will show again as disabled.

I tried to use

document.pizza.field07.disabled = false ;

It does disables the field, by clicking reset or hitting back button still keeps it enable.

Please guide.

Answer 1

To access this element in a more standard way, use document.getElementById with setAttribute

document.getElementById("field07").setAttribute("disabled", false);

EDIT

Based on your comment, it looks like field07 is a name, not an id. As such, this should be what you want:

var allfield7s = document.getElementsByName("field07");
for (var i = 0; i < allfield7s.length; i++)
    allfield7s[i].setAttribute("disabled", false);

Answer 2

That is the only working solution for Me:

var allfield7s = document.getElementsByName("field07");
for (var i = 0; i < allfield7s.length; i++)
    allfield7s[i].removeAttribute("disabled");

Answer 3

You can enable a disabled html control with the following JavaScript code.

document.getElementById('elementId').removeAttribute('disabled');
