Iterating through an unknown length array of textareas, using Javascript

Question

I'm trying to iterate through an array of textareas on my page with ClassName TextInput and change their values ( innerHTML ). The function I wrote is as follows-

    function init() {
        var TextInput[] = document.getElementByClassName("TextInput"); //line 12
        for(var i = 0; i < TextInput.length; i++) {
            TextInput[i].innerHTML = "N/A";
        }
    }

Firefox 18.0.2's debug console says SyntaxError: missing ; before statement SyntaxError: missing ; before statement on line 12.

What is wrong with my code and how can I achieve what I'm trying to do?

Answer 1

You don't need to add [] , just

var TextInput = document.getElementByClassName("TextInput"); //line 12

Edit: And as @Benjamin pointed out, the function name is missing a s .

This should work:

var TextInput = document.getElementsByClassName("TextInput"); //line 12
