<div class="input-group">
<input id="courseInput" type="text" data-role="item-input" class="form-control">
<span class="input-group-btn">
<button id="addItemCourse" class="btn btn-default" type="button" data-role="item-add" >添加</button>
</span>
</div>
</div>
</div>
</form>
<!-- container -->
</div>
<script type="text/javascript" src="${app.basePath}/resources/js/jquery.form.js"></script>
<script>
$.schoolFn = {
addCourseItem: function(obj){
$("#ItemCourseList").append("<li class='list-group-item clearfix'><span class='glyphicon glyphicon-resize-vertical sort-handle'></span>"+obj+"<input type='hidden' name='goals' value='"+obj+"'><button type='button' class='close delete-btn deleteItem' onclick='deleteCourseItem(this);' title='删除'>×</button></li>");
},
addItem: function(obj){
$("#itemList").append("<li 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>");
},
}
$("#addItemCourse").click(function(){
var item=$('#courseInput').val();
if(item.trim()==""){
$('#courseInput').val("");
}else{
$.schoolFn.addCourseItem(item);
$('#courseInput').val("");
}
});
function deleteCourseItem(obj){
$(obj).parent().replaceWith("");
}
</script>
<script>
$(document).ready(function(){
$('#addressForm').ajaxForm(function(json) {
if(json.status == "success") {
$("#onFailureDiv").html("添加成功").slideDown().delay(3000).hide(1000);
}else {
$("#onFailureDiv").html(json.errorMsg).slideDown().delay(3000).hide(1000);
}
