js判断手机或者电脑端

function IsPC() {
	var userAgentInfo = navigator.userAgent;
	var Agents = ["Android", "iPhone",
	            "SymbianOS", "Windows Phone",
	            "iPad", "iPod"];
	var flag = true;
	for (var v = 0; v < Agents.length; v++) {
	    if (userAgentInfo.indexOf(Agents[v]) > 0) {
	        flag = false;
	        break;
	    }
	}
	return flag;
}
 
var flag = IsPC(); //true为PC端，false为手机端
console.log(flag)
