javascript: how to make Input non editable

Do you want dynamically set the input non-editable?
Here we go:

var setNonEditable=true;

var input =document.getElementById("InputId");

//#1 In this case - the value won't be save in the input field event it presents there

if(setNonEditable)

 {

    input .style.visibility = 'hidden';

 }

else

 {

   input .style.visibility = 'visible';

  }

//#2 The value will be saved even the input is not editable but value is in there

if(setNonEditable)

 {

   input .disabled = true;

 }

else

 {

     input .disabled = false;

  }

Happy easy coding!
