Find space at cursor in TEXTAREA

Is there anyway to check if the character at the cursor in TEXTAREA is a "space"? If it is, return TRUE. Let me know how to do this using jQuery.

Thanks

This works in recent versions of the main browsers and has the added bonus of not requiring jQuery or any other library:

function nextCharIsSpace(textArea) {
    var selectedRange, range, selectionEndIndex;

    // Non-IE browsers
    if (typeof textArea.selectionEnd == "number") {
        selectionEndIndex = textArea.selectionEnd;
    }

    // IE is more complicated
    else if (document.selection && document.selection.createRange) {
        textArea.focus();
        selectedRange = document.selection.createRange();
        range = selectedRange.duplicate();
        range.moveToElementText(textArea);
        range.setEndPoint("EndToEnd", selectedRange);
        selectionEndIndex = range.text.length;
    }
    return textArea.value.charAt(selectionEndIndex) === " ";
}
