使用click事件，很难确定在拖动开始和结束的时候触发，所以使用了onmouseup（释放鼠标的时候），释放鼠标的时候，即在拖动还未结束，但是准备处理的阶段，此时mouseButtonFlag按照逻辑来说应该是true，即不会触发绑定的事件。
1.将click转为使用onmouseup事件
2.添加mouseButtonFlag对象，判断是否拖拽情况，用以处理是否触发鼠标释放（点击）事件

需要处理的是，拖动图片的时候，不能触发点击事件

处理的JS
var mouseButtonFlag = false;//控制是否触发点击事件
//拖动
$('#acAlbums').sortable({
items: "li:not(.add)",
start: function (event, ui) {
mouseButtonFlag = true;
},
stop: function (event, ui) {
mouseButtonFlag = false;
}
});
//打开轮播图片设置的弹窗
function openImageSetDialog(obj,v) {
if (mouseButtonFlag) {
return;
}
if (v!=undefined) {//添加图片对象
$("#show_image_1").attr("src", "/Content/Images/Scene/Vote004/jia.jpg");
$("#image_url_txt").val("http://ttyouni.com/show/index")
}
else {
$("#show_image_1").attr("src", $(obj).attr("src"));
$("#image_url_txt").val($(obj).attr("url"))
}
$("#image_index_txt").val($(obj).parents("#acAlbums li").index())
$("#choose_activebox1").show();
}
