根据if更改backgroundPosition图像

Question

$(".addon-checkbox").style.backgroundPosition = 
     if(localStorage["__Enable__"+__addons[i]] != "yes") "0 -50px";
     else "0 0";

如何使此代码正确？

Answer 1

jQuery对象没有style属性？

var bg = localStorage["__Enable__"+__addons[i]] != "yes" ? "0 -50px" : "0 0";

$(".addon-checkbox").css('background-position', bg);

Answer 2

也许：

$(".addon-checkbox").get().style.backgroundPosition = 
     (localStorage["__Enable__"+__addons[i]] != "yes") ? "0 -50px" : "0 0";
