图片加载后会出现黑线
右击下载图片则显示正常
，调试情况下也显示正常，刷新后则不再出现。
贴上代码
var drawtable = [];
var handlerUrl = "/xxx/xxxHander.ashx?v=" + Math.random();
//获得画
$.ajax({
async: false,
type: "POST", //GET
url: encodeURI(handlerUrl),
data: "action=drawimage,
beforeSend: function (XMLHttpRequest) {
$("<div class='loadingWrap'></div>").appendTo("body");
},
success: function (data, textStatus) {
if (data != "") {
var jsonObj = JSON.parse(data);
var imagegriddiv = document.getElementById("imagegrid");//
for (var i = 0; i < jsonObj.length; i++) {
movenullstr(jsonObj[i]);
var imageindex = parseInt($("#<%=hideImageIndex.ClientID %>").val()) + 1;//获得当前页面的id
var div = document.createElement("div");
var img = document.createElement("img");

div.className = "grid__item";

}
}
},
