我在bootstrap中有一个表 - 如何添加包含所选行的删除按钮的列？

Question

I created a table in bootstrap, basically it contains different columns and rows, eg:

<thead>
    <tr>
        <th>Location</th>
        <th>Date</th>
        <th>Time</th>
        <th>Duration</th>
        <th>Content</th>
        <th>Remove</th>
    </tr>
</thead>
<tbody>
    <tr class="odd gradeX">
        <td>Trident</td>
        <td>Internet Explorer 4.0</td>
        <td>Win 95+</td>
        <td class="center">4</td>
        <td class="center">X</td>
        <td class="center">Remove</td>
    </tr>
    <tr class="even gradeC">
        <td>Trident</td>
        <td>Internet Explorer 5.0</td>
        <td>Win 95+</td>
        <td class="center">5</td>
        <td class="center">C</td>
        <td class="center">Remove</td>
    </tr>
    (...)

So far the last column contains static 'Remove' string. Is there a way of dynamically removing the row when the user hits the remove link there?

here is my fiddle: http://jsfiddle.net/fyw6kajm/1/

Answer 1

Or you can wrap your Remove in last td inside an anchor tag with some class name given to it, say remove and write a click event to that class.

Ex:

HTML

<tr class="odd gradeA">
     <td>Trident</td>
     <td>Internet Explorer 5.5</td>
     <td>Win 95+</td>
     <td class="center">5.5</td>
     <td class="center">A</td>
     <td class="center"><a class='remove' href="#">Remove</a></td> <!--wrap in anchor tag-->
</tr>
<tr class="even gradeA">
     <td>Trident</td>
     <td>Internet Explorer 6</td>
     <td>Win 98+</td>
     <td class="center">6</td>
     <td class="center">A</td>
     <td class="center"><a class='remove' href="#">Remove</a></td>
</tr>

JS

$('.remove').on('click',function(){
   $(this).closest('tr').remove(); //remove its root parent tr using closest
});

if the contents are dynamically added you can do event delegation as below:

$("#dataTables-example").on('click','.remove',function(){
   $(this).closest('tr').remove(); //remove its root parent tr using closest
});

DEMO

Answer 2

You can have delegated click event on last td of row or the row that contains text remove along with .closest() and .remove() for traversing to closest row and removing it respectively:

$('body').on('click','td:contains(Remove)',function(){
  $(this).closest('tr').remove();
});

Working Demo

Answer 3

Make the buttons.

 $("#trigger-overlay2").click(function() { // $(this).toggleClass("active"); $(".overlay-boxify2").toggleClass("open"); }); $(document).on('click','.tr_remove',function(e){ e.preventDefault(); $(this).parents('tr').remove(); }); 

 .overlay-boxify, .overlay-boxify2 { visibility: hidden; opacity: 0; -webkit-transition: opacity 0.5s, visibility 0s 0.5s; transition: opacity 0.5s, visibility 0s 0.5s; } .overlay-boxify.open, .overlay-boxify2.open { visibility: visible; opacity: 1; -webkit-transition: opacity 0.5s; transition: opacity 0.5s; z-index:9999; } .overlay2 { position: fixed; top: 0; left: 0; width: 100%; height: 100%; background-image: url(../img/grid.png); background: rgba(222, 222, 222, 0.95); overflow: scroll; }

Answer 4

This removes the entire tr/row-element and its children, but you should assign a class to your remove button that is specific to this function, eg js_remove_row. Because this handle: "tr > td:last-child" could target other stuff if you change your table. Notice the js-prefix which lets you know that this class is a javascript-handler and not used for styling. I also use $(document).on... because if doesn't break if you ajax-load part of your page or table, document is always there and you don't have to reset the handler if reloading your content.

This works:

$(document).on("click", "tr > td:last-child", function() {
  $(this).parent().remove(); 
});

This is better:

<td class="center js_remove_row">Remove</td>

$(document).on("click", ".js_remove_row", function() {
      $(this).parent().remove(); 
    });

Answer 5

You just need to add class to call click event on remove td and add click event to remove like below:

fiddle

<td class="center removetd">Remove</td>

Jquery:

$(".removetd").click(function(){
  $(this).closest("tr").remove();
});

Answer 6

Try attaching click event to tr element , using event.target , Node.textContent , calling $(this).remove() if event.target text is "Remove"

 $("tr").click(function(e) { if (e.target.textContent === "Remove") $(this).remove() }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <table> <thead> <tr> <th>Location</th> <th>Date</th> <th>Time</th> <th>Duration</th> <th>Content</th> <th>Remove</th> </tr> </thead> <tbody> <tr class="odd gradeX"> <td>Trident</td> <td>Internet Explorer 4.0</td> <td>Win 95+</td> <td class="center">4</td> <td class="center">X</td> <td class="center">Remove</td> </tr> <tr class="even gradeC"> <td>Trident</td> <td>Internet Explorer 5.0</td> <td>Win 95+</td> <td class="center">5</td> <td class="center">C</td> <td class="center">Remove</td> </tr> (...) </table>
