String is not a function JavaScript

Question

I want to set a value to a field, this is the html:

<form name="myForm"> 
<input type="text" id="user">
</form>

And the javascript:

window.onload = init;
function init() {
generateUser();
//more code... 
}

function generateUser(){
var generated = "usr_"+Math.floor((Math.random() * 1000) + 1);
document.myForm.user.value(generated);
}

I cant find a way to set that value, always getting "String not a function".

value isn't a function. It's a string. It's the value of the input field. — gen_Eric

Should be:

document.myForm.user.value = generated;

It is not a method it is a property...

Exists very useful function to find element in any place on the page by element id - getElementById, you can use it

document.getElementById("user").value = generated;
