Getting textbox value(or itself) in javascript results in null

Question

code:

<input name="xy" size="2" type="text" />

this is meant to be a textbox, looks like and functions like one.

js:

  alert(document.getElementById("xy"));

and this returns null. If I try to get value of it or whatever, I simply get nothing.

Any reason ? (p.s: javascript works fine and its external)

There is no element with an id of "xy", so getElementById doesn't find one. — David

Just set an id :

<input id="xy" name="xy" size="2" type="text" />

getElementById take the id attribute, not the name.

As our friend Ren said:

getElementById gets by the id, so you should set and id

But if you need to use the name atribute you could use: document.getElementsByName
