复制代码 代码如下:

<script>
$.schoolFn = {
addItem: function(obj){
$("#itemList").append("<li id='liItrm' class='list-group-item clearfix'><span class='glyphicon glyphicon-resize-vertical sort-handle'></span>"+obj+"<input type='hidden' name='audiences' value='"+obj+"'><button type='button' class='close delete-btn deleteItem' onclick='deleteItem(this);' title='删除'>×</button></li>");
},

removeItem: function(obj){
$("#"+obj).replaceWith("");
}
}
$("#itemAdd").click(function(){
var item=$('#teacherInput').val();
$.schoolFn.addItem(item);
$('#teacherInput').val("");
});
function deleteItem(obj){
var item=$(obj).parents(".list-group-item").attr("id");
$.schoolFn.removeItem(item);
}
</script>
