使用单选按钮将文本输入动态添加到列表中

Question

I have a list (style taken from bootstrap) of elements, to which I want to add some more elements using text input. Here is my code-

<div class="col-lg-6">

    <div class="input-group">
      <input type="text" id = "input" class="form-control">
      <span class="input-group-btn">
      <button class="btn btn-default" type="button" id = "add" >Add</button>
      </span>

    </div><!-- /input-group -->
<form>
    <ul class="list-group" id = "tagList">

  <li class="list-group-item"> <b>Tags </b></li>  
  <li class="list-group-item"> <span class ="input-group-addon">
    <input type="radio">
    </span>Apple</li>
  <li class="list-group-item"> <span class ="input-group-addon">
    <input type="radio">
    </span> Orange</li>
  <li class="list-group-item"> <span class ="input-group-addon">
    <input type="radio">
    </span> Pear</li>
  <li class="list-group-item"> <span class ="input-group-addon">
    <input type="radio">
    </span> Banana</li>
</ul>
</form>


<script src="http://codeorigin.jquery.com/jquery-2.0.3.js"></script>

<script>

$('#add').click(function(){
    var text = $('#input').val();
    if(text.length){
        $('<li />', {html: text}).appendTo('ul.tagList')
    }
});

 </script>

I can get the code to work with a simpler list, but not with this one. Can anyone spot why not?

Answer 1

Your li's are not closed:

 <li class="list-group-item" <span class ="input-group-addon">
    <input type="radio">
    </span>Apple</li>

Should be:

 <li class="list-group-item"><span class ="input-group-addon">
    <input type="radio">
    </span>Apple</li>

Always funny to spot such issues once you placed the code into the code highlighting here on SO.

In order for your javascript to work, you might use the following: http://jsfiddle.net/jX2K3/21/

Answer 2

try following code..

    $('#add').click(function(){
    var text = $('#input').val();
    if(text.length){        
    $('ul').append('<li class="list-group-item"><span class ="input-group-addon"> <input type="radio">    </span>'+text+'</li>');
    }
});
