You can do that, or you can assign the object itself to a variable. Like so

您可以这样做,或者您可以将对象本身分配给变量。像这样

var iconName = ".icon a";
$(iconName).hover(function(){ });

or

var $icon = $(".icon a");
$icon.hover(function () { });

or even both

甚至两者

var iconName = ".icon a";
var $icon = $(iconName);
$icon.hover(function () { });
