窄屏简体版字體: 小|中|大|超大

var oPopup = window.createPopup();

function rdl_doClick(){

var oMessage=document.all("oMessage");

with (oPopup.document.body) {

style.backgroundColor="lightyellow";

style.border="solid black 1px";

innerHTML=oMessage.value;

}

oPopup.show(70, 70, 180, 60);

}

</script>

<a href="#" onmouseover="rdl_doClick()" onmouseout="oPopup.hide();">显示弹出窗口 </a>

还有用titile

由js控制的代码，还可以临时解决 alt 显示速度慢的问题
