无法读取未定义的属性"innerHTML"
Cannot read property 'innerHTML' of undefined

}
}
t.ljs = g
}
f && r(f)
})(window);
但是我是javascript的新手，我不知道如何解决它(我想测试这个应用程序)
But I'm a novice with javascript and I don't know how to fix it (i'd like to test this app)
谢谢！
推荐答案
这仅意味着您要查找的元素不存在:
That just means that the element that you are looking for does not exist:
var elementNotFound = document.getElementById("noSuchId"); // Does not exist
console.log("The element:", elementNotFound);
console.log(elementNotFound.innerHTML);
当您发布了经过简化的JavaScript且没有HTML时，我不知道如何进一步帮助，然后说:使用您用来查找元素的ID是正确的并且没有拼写错误，并且该元素是实际上在HTML中.
As you have posted the mimified JavaScript and no HTML, I don't know how to help further then saying: Make use the ID you are using to find the element is correct and has no spelling mistakes, and that the element is actually in the HTML.
希望这会有所帮助.
