Javascript document.getElementById(“id”).value returning null instead of empty string when the element is an empty text box

Question

I have a text box element whose value I am trying to access using document.getElementById(\"id-name\").value. I find that the call is returning a null instead o

Answer 1

For your code

var mytextvalue = document.getElementById("mytext");

mytextvalue will contain null if you have a document.write() statement before this code. So remove the document.write statement and you should get a proper text object in the variable mytextvalue.

This is caused by document.write changing the document.
