jQuery弹层提示效果
这段代码是我根据网上的一些示例代码加以变形后产生的，按照这个方法可以实现弹层提示的效果，同时实现了覆盖原有的层的效果。各位有需要的话可以按情况改变提示层的样式以适应各自的需求。调用时可以这么写：Page.ClientScript.RegisterStartupScript(Page.GetType(),
"myscript", ""); //弹层提示脚本//显示灰色JS遮罩层function showBg(ct, content,
forShowInfo) { var bH = $("body").height(); var bW =
$("body").width() + 16; var objWH = getObjWh(ct);
$("#fullbg").css({ width: bW, height: bH, display: "block" });
var tbT = objWH.split("|")[0] + "px"; var tbL =
objWH.split("|")[1] + "px"; $("#" + ct).css({ top: tbT, left:
tbL, display: "block" }); $("#" + content).html("
