Hi, I was wondering if it was possible to do something like this in javascript? eg: Say I have 3 textfields called obj1, obj2 and obj3. for(var i=1;i<4;i++) { //1 to 3 (obj+i).value = "whatever"; } Although this code doesn't work, is there someway to actually do it like so?, as I remember one of my college teachers showing me another students javascript code who had done something like that, but now I can't remember how. Or is there a way to get all input/text area objects in the page without specifying each of their names, eg automatically recall all the names? Thanks.

Q Is it possible to do this in javascript?
A Yes. For all reasonable 'this'.

for(var i=1;i<4;i++) { //1 to 3
document.getElementByID["obj"+i].value = "whatever";
}

should work if I didn't overlook some typo
