I have a form with 2 text boxes that all do the same thing. They each call the JQuery function below after each keypress. Since I have 2 textboxes that all do the same thing, I'd like this function to work for both. How do I change this function so that it'll grab the textbox's ID that is currently开发者_C百科 being edited instead of just the one?

The part where I'd like to insert my textbox's id is '#DocId'.

$(function() {
    $('#DocId').live('keydown', function() {    
        var styleValue = $(this).val();
        $('#tableContent').load(
            '/CurReport/TableResults',
            { style: styleValue }
        );
    })
});

Here is my HTML:

<td><%= Html.TextBox("DocId") %></td>
<td><%= Html.TextBox("LangCode") %></td>

Thank you,

Based on your edit, this will work:

$('#DocId, #LangCode, #ThirdBoxIDHere').live('keyup', function() {    
  $('#tableContent').load('/CurReport/TableResults', { style: $(this).val() });
})

This is assuming they all use #tableContent, if not then it'll need to be able to get at an attribute on something to determine that.

Something like this maybe:

<body>

<textarea class="commonClassName" name="DocId" id="DocId" rows="8" cols="40"></textarea>
<textarea class="commonClassName" name="DocId2" id="DocId2" rows="8" cols="40"></textarea>

<div id="tableContent" style="border: 2px solid #678;padding: 1em;">

</div>
<script type="text/javascript">
$(function() {
    $('.commonClassName').live('keyup', function() {    
        var styleValue = $(this).val();
        // do your own magic here
        $('#tableContent').html(styleValue);
    })
});

</script>
</body>

Using a classname to attach live to both elements here.
I used keyup to avoid a one-character lag.

You can get the ID by $(this).attr('id') and change your selector to $('#DocId, #LangCode').
