HTML实现简单的提示框

<script src="http://cdn.static.runoob.com/libs/jquery/2.1.1/jquery.min.js"></script>

<script>

function show(obj,id) {

var objp = $("#"+id+"");

/**

   这里我们可以使用ajax从数据库获取数据动态改变提示框里的内容

   $.post('./test.php',{act:"ajax_get_ifo", goods_id:goods_id}, function (res){

                objp.html("<br>"+res.data+"<br>");

            }, 'json');

**/

$(objp).css("display","block");

$(objp).css("left", event.clientX + 30);

$(objp).css("top", event.clientY - 45);

}

function hide(obj,id) {

var objp = $("#"+id+"");

$(objp).css("display", "none");

}

</script>

<p id="myp1" style="position:absolute;display:none;border:1px solid silver;background:gray;filter:alpha(Opacity=80);-moz-opacity:0.5;opacity: 0.7;">

提示1效果

</p>

<p id="myp2" style="position:absolute;display:none;border:1px solid silver;background:silver;filter:alpha(Opacity=80);-moz-opacity:0.5;opacity: 1.0;">
