使用jquery trigger 触发a标签的click事件取代window.open方法

var ohtml='<div class="friend-dialog tac pt15 pb20">'+
'<div class="f-h32">您已经成功发送好友申请。</div>'+
' <p class="c999">上传真实头像，好友申请更容易被通过哦，赶紧上传头像吧！</p> '+
'<a href="<%=path%>/teacher/editUserAvatar.action" target="_blank"><span id="awindowopen" ></span></a>'+
'  </div>';
$.dialog({
lock:true,
title: '温馨提示',
button: [
{value: '点击上传图像',callback: function () {
$("#awindowopen").trigger("click");
},focus: true
}
],
content:ohtml
});

<a href="<%=path%>/teacher/editUserAvatar.action" target="_blank"><span id="awindowopen" ></span></a>
