easyui弹出层

1.效果图如下（该页面完成了数据添加，图片上传，图片数据回显功能，本篇文章主要介绍弹出操作）：

2.点击“新增”按钮弹出添加信息的框，首先引入一套easyui和jquery 

3.html代码：

   <a href="#" class="easyui-linkbutton" plain="true" onclick="newAdd()" icon="icon-add">新增</a>



<div id="win" class="easyui-dialog" title="班级信息添加"  style="width: 400px; padding: 10px 20px; height: 410px;"
     closed="true" buttons="#dlg-buttons">

    <form id="fm" method="post" action="" style="margin-top: 20px; margin-left: 20px;">
        <div class="fitem">
            <label>贷款人数:</label>
            <input id="dkrs" style="" name="" class="easyui-textbox"  />
        </div>
        <div class="fitem">
            <label>班级名称:</label>
            <input id="bjmc" name="" class="easyui-textbox" />
        </div>
        <div class="fitem">
            <label>班级人数:</label>
            <input id="bjrs" name="" class="easyui-textbox" />
        </div>

        <div class="fitem">
            <label>老师名称:</label>
            <input id="lsmc" name="" class="easyui-textbox"  />
        </div>

        <div class="fitem">
            <label>辅导员名称:</label>
            <input id="fdymc" name="" class="easyui-textbox"  />
        </div>

        <div class="fitem">
            <label>辅导员编号:</label>
            <input id="fdybh" name="" class="easyui-textbox"  />
        </div>
        <div class="fitem">
            <label>辅导员头像:</label>
            <input type="file" name="file_upload2" id = "uplx" accept="image/gif,image/jpeg,image/jpg,image/png,image/svg" onchange="imgPreview(this)" >
        </div>
        <div id="Imgdiv" class="fitem">
            <label></label>
            <img id="preview" width="200px" height="200px" placeholder="预览"/>
        </div>
        <!--直接写提交取消的事件不需要在js中绑定-->
        <div id="dlg-buttons" style="display: block">
            <a id="confirm" href="javascript:void(0)" class="easyui-linkbutton c6" iconcls="icon-ok" onclick="Modify()" style="width: 90px">提交</a>
            <a href="javascript:void(0)" class="easyui-linkbutton" iconcls="icon-cancel" onclick="javascript:$('#win').dialog('close')" style="width: 90px">取消</a>
        </div>
    </form>
</div>

4.js代码：

function newAdd(){
    $('#win').dialog('open');
}
