jQuery: get table id by click in td

问题:

I have a tr in a table header that contains several input fields.

Is there a way that by click on one of these input fields I can get the id of the parent table ?

My tr looks like this:

<table id="tableID">
    <thead>
        <tr>
            <th><input type="text" name="input1" id="input1" /></th>
            <th><input type="text" name="input2" id="input2" /></th>
            <th><input type="text" name="input3" id="input3" /></th>
        </tr>
    </thead>
    <tbody>
        // ...
    </tbody>
</table>

Thanks for any help with this, Tim.

回答1:

In the click handler you can use .closest()

$(this).closest('table').attr('id')

回答2:

$("#tableID").on("click","input[type='text']",function(){

$(this).closest('table').attr('id');

});

reference closest()

回答3:

You can use

$('#tdId').click(function(){
    $(this).parents('table').attr('id');
});

it works.

You should delegate event to avoid multiple handlers, and then use delegateTarget to target current TABLE:

$('table').on('click', 'input', function (e) {
    alert(e.delegateTarget.id);
});
