我使用這個代碼來設置和刪除按鈕禁用的屬性在我的網頁上:如何從我的頁面上的按鈕元素中刪除殘疾人?
if (localStorage.buttonColor) {
document.getElementsByTagName('html')[0].className = localStorage.buttonColor;
var themeButtons = document.querySelectorAll(".theme");
for (var button in themeButtons) {
themeButtons[button].removeAttribute("disabled");
}
document.querySelector('button[name="' + localStorage.buttonColor + '"]').disabled = true;
}
但它給我一個消息說:
Uncaught TypeError: Object 0 has no method 'removeAttribute'
能有人給我建議在這個?
