我对 html 的工作不多，但我需要有两个列表，我可以从一个列表中选择另一个列表。像 ：

在此处输入图像描述

这是 html 代码，但从一个列表到另一个列表的选择不起作用：

<!DOCTYPE html>
<html>
<head>
<script>
$().ready(function() {  
   $('#add').click(function() {  
    return !$('#select1 option:selected').remove().appendTo('#select2');  
   });  
   $('#remove').click(function() {  
    return !$('#select2 option:selected').remove().appendTo('#select1');  
   });  
  });
</script>
<style type="text/css" media=screen>
a {  
   display: block;  
   border: 1px solid #aaa;  
   text-decoration: none;  
   background-color: #fafafa;  
   color: #123456;  
   margin: 2px;  
   clear:both;  
  }  
  div {  
   float:left;  
   text-align: center;  
   margin: 10px;  
  }  
  select {  
   width: 100px;  
   height: 80px;  
  } 
</style>
</head>
<body>

<div>  
  <select multiple id="select1">  
   <option value="1">Option 1</option>  
   <option value="2">Option 2</option>  
   <option value="3">Option 3</option>  
   <option value="4">Option 4</option>  
  </select>  
  <a href="#" id="add">add &gt;&gt;</a>  
 </div>  
 <div>  
  <select multiple id="select2"></select>  
  <a href="#" id="remove">&lt;&lt; remove</a>  
 </div>  

</body>
</html>

我只是没有看到我的错误是什么。欢迎大家提出意见。

使用 document.ready 。你放置了错误的代码

代替

$().ready(function()

和

$(document).ready(function()

试着放

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.2/jquery-ui.js"></script>

你没有包含 jQuery 文件。

使用以下代码删除和附加选项。

$('#select1:selected').each(function(i, selected) {
    $("#select2").append('<option 
     value='+$(selected).val()+'>'+$(selected).text()+'</option>');

    $(this).remove();  
});

您可以在这里找到一个工作示例http://www.bootply.com/126254

$('.add').click(function(){
    $('.all').prop("checked",false);
    var items = $("#list1 input:checked:not('.all')");
    var n = items.length;
  	if (n > 0) {
      items.each(function(idx,item){
        var choice = $(item);
        choice.prop("checked",false);
        choice.parent().appendTo("#list2");
      });
  	}
    else {
  		alert("Choose an item from list 1");
    }
});

$('.remove').click(function(){
    $('.all').prop("checked",false);
    var items = $("#list2 input:checked:not('.all')");
	items.each(function(idx,item){
      var choice = $(item);
      choice.prop("checked",false);
      choice.parent().appendTo("#list1");
    });
});

/* toggle all checkboxes in group */
$('.all').click(function(e){
	e.stopPropagation();
	var $this = $(this);
    if($this.is(":checked")) {
    	$this.parents('.list-group').find("[type=checkbox]").prop("checked",true);
    }
    else {
    	$this.parents('.list-group').find("[type=checkbox]").prop("checked",false);
        $this.prop("checked",false);
    }
});

$('[type=checkbox]').click(function(e){
  e.stopPropagation();
});

/* toggle checkbox when list group item is clicked */
$('.list-group a').click(function(e){
  
    e.stopPropagation();
  
  	var $this = $(this).find("[type=checkbox]");
    if($this.is(":checked")) {
    	$this.prop("checked",false);
    }
    else {
    	$this.prop("checked",true);
    }
  
    if ($this.hasClass("all")) {
    	$this.trigger('click');
    }
});
