根据不同的分辨率调用不同的css

var Other1600 = "css_1600.css";
var Other1440 = "css_1440.css";
var Other1366 = "css_1366.css";
var Other1280 = "css_1280.css";
var Otherother = "";

//ScreenWidth()

function ScreenWidth() {
    // alert(screen.width >= 1366 && screen.width < 1440)

    if (screen.width >= 1600){

        setActiveStyleSheet(Other1600);
       }

    if (screen.width >= 1440 && screen.width < 1600){
        setActiveStyleSheet(Other1440);
    }

    if (screen.width >= 1360 && screen.width < 1440){ 

       // setActiveStyleSheet(Other1366);
     }

    if (screen.width >= 1280 && screen.width < 1366){
        setActiveStyleSheet(Other1280);
       }

}
function setActiveStyleSheet(title) {
   document.getElementsByTagName("link")[2].href = "css/" + title;
}
