Question

I’m trying to get the String value out of a text area using

var name = $('textarea#myTextBox').val();

However, this seems to output undefined. I know this because I have a check in my JS after this code that says name = "5"+name+"4";

I then send name to a C++ file using Awesomium, and the name is processed through the below line:

String name = Convert::toString(params[L"name"].toString());

When I see what my name is set to, it reads “5undefined4”

EDIT: My CSS is simply this:

#myTextBox {
   position: absolute;
   top: 78%;
   left: 40%;
}

I’ve had my html set as:

<textarea id="myTextBox" rows="1" col="20" maxlength="18"></textarea>

Which makes the text area “listen” to the CSS and be placed in the correct position, but I get null as my string.

I’ve also tried:

<div class="myTextBox">
    <textarea id="nameBox" rows="1" col="20" maxlength="18"></textarea>
</div>

Which then the textarea does not listen to the CSS and it still returns null

What does alert($('textarea#myTextBox').length); say? – alex

@alex It says 0 – Briz

Your selector is incorrect.

For that selector to work, your HTML should look like…

<textarea id="myTextBox" rows="1" cols="1" name="something"></textarea>

The id attribute is the important one.
