获取当前页面的缩放值，来修改样式！
function detectZoom (){
var ratio = 0,
screen = window.screen,
ua = navigator.userAgent.toLowerCase();
if (window.devicePixelRatio !== undefined) {
ratio = window.devicePixelRatio;
}
else if (~ua.indexOf('msie')) {
if (screen.deviceXDPI && screen.logicalXDPI) {
ratio = screen.deviceXDPI / screen.logicalXDPI;
}
}
else if (window.outerWidth !== undefined && window.innerWidth !== undefined) {
ratio = window.outerWidth / window.innerWidth;
}
if (ratio){
ratio = Math.round(ratio * 100);
}
return ratio;
};
//开始判断
if(detectZoom()==200){
}else{
}
