selecting the entered text in an input form

[Sarah Atkinson]

I simply don't understand JavaScript one bit.

I made a small script in PHP and now i have to create the same script in javascript.

So I have a small form and when the form is submitted I want the value entered into the field to be sent to a function as a variable

$(document).ready(function() {
$("form").submit(function(){
 var enteredValue=$('input[name="x"]').value;
 grabvalue(enteredValue);
 });
});
function grabvalue(value)
{
alert(value);
}

but this doesn't work played with it and all I can get is either [object Object] or undefined
What am I doing wrong?

Looks like you're using jQuery, so you'd want to use the val() method instead of a value property.

Try this:

var enteredValue=$('input[name="x"]').val();
