jquery.jmpopups.js 弹出层 进行进度显示(遮罩层)

/**
* 显示loading画面
* @param desc
* @return
*/
function showLoading(desc) {

$("body").append("<div id=\"processingdiv\" style=\"display:none;\"><div class=\"popup\"> <div class=\"popup-body\"><div class=\"loading\"><span>"+desc+"</span></div></div></div></div>");

//alert($("head").html());

$.openPopupLayer({
name: "processing",
width: 500,
target: "processingdiv"
});
}

/**
* 关闭loading画面
* @param desc
* @return
*/
function hideLoading() {
$.closePopupLayer('processing');
$("#processingdiv").remove();
}

showLoading--表示显示进度条

hideLoading-表示隐藏
