		var img = document.getElementById(\'img\')
		var s1,s2
		console.log(img)
		// 图片放大效果
		i = 100;
		img.addEventListener(\'mouseover\',function(){
			clearInterval(s1);
			s1 = setInterval(function(){
				i+=0.1;
				img.style.width = (i)+\'%\';
				img.style.height = (i)+\'%\';
				i = parseFloat(i);
				if(i>=120) clearInterval(s1);
			},1);
		})
		img.addEventListener(\'mouseout\',function(){
			clearInterval(s2);
			s2 = setInterval(function(){
				i-=0.1;
				img.style.width = (i)+\'%\';
				img.style.height = (i)+\'%\';
				i = parseFloat(i);
				if(i<=100) clearInterval(s2); 
			})
		})
