如何在php中使用以下代码?
var life=parseFloat(this.hp)/parseFloat(this.maxhp);
document.getElementById('life2').style.width=Math.round(1+106*life)+"px";
addEvent(document.getElementById('life1'),'mouseover',function (e) {
if(!e)var e=window.event;
tip.show(e.clientX,e.clientY,'','<B>Punkty życia:</B>'+hero.hp+'/'+hero.maxhp);
});
