How to Remove dynamic Parent <tr> via OnClick of child <input>

I'm adding the <tr> via a Javascript var:

var txtBox = "<tr id='dynTR'><td><input type='text' class='textBoxes' /></td><td><input type='text' class='textBoxes' value='0' /></td><td><input type='button' value='-' /></td></tr>";

With my function being:

function AddTR(table) {
            $(table).append(txtBox);
        }

My table structure (along with开发者_如何学JAVA the button for the function) in the HTML being:

<table id="tblTest" class="testTable">
            <thead>
                <tr>
                    <td>Product</td>
                    <td>Quantity</td>
                    <td>Remove TR</td>
                </tr>
            </thead>
            <tbody>

            </tbody>
        </table>
        <br />
        <input type="Button" id="btnTest" value="Add Table Row" onclick="AddTR($('#tblTest'))" />

So how do I go about using the .remove() function in jQuery to get rid of the parent tag without accidentally removing all <tr id='dynTR'> tags?

Considering this one is the remove button:

<input type='button' value='-' />

The following will do:

$('#tblTest input[type="button"]').click(function () {
     $(this).closest('tr').remove();
});

I'd suggest you use jQuery event handlers instead of using inline onclick and friends. $(this) is the jQuery object of the button that was clicked, .closest() will look in the parents of the button and find the first tr, then remove it.

The best way would be to change the HTML for your remove button:

<input type='button' value='-' class='removeButton' />

so you can target your remove button like this:

$('#tblTest .removeButton').click(...

This is better because with the previous example, every possible input type="button" in the table would get the event, even though we just need it on these special ones (not a problem if there are no other buttons in the table).

bazmegakapa answer should do the trick. Also you should really avoid using inline Javascript, it's generally bad practise. Instead do:

$('#btnTest').click(function() { AddTR($('#tblTest')); });

Also to keep up with the convention of jQuery using the correct scope of the element object, you could do:

$('#btnTest').click(function() { AddTR.call($('#tblTest')[0]); });

Then in your AddTR function you can simply reference the element table as this

function AddTR() {
    $(this).append(txtBox);
}

It keeps things predictable and follows the same convention.

Hang on a minute....

In theory although the AddTR() function is adding a table row, it's a bit misleading because all it's doing is just appending an element to that context. What you really want to do is just what the function says; add a table row! instead your doing

var txtBox = "<tr id='dynTR'><td><input type='text' class='textBoxes' /></td><td><input type='text' class='textBoxes' value='0' /></td><td><input type='button' value='-' /></td></tr>";

Which is rather ugly and will cause some changes if you change your table row structures. Instead, use .clone to help you:

function AddTR() {
   $(this).append($('tr:last').clone());
}
