JavaScript - 启用/禁用单选按钮的复选框

Question

IM SO CLOSE!我很近！ by default, the buttons are enabled.默认情况下，按钮处于启用状态。 also when checked both are enabled but when unchecked only one is disabled.同样，在检查两者时，都将启用两者，但是如果未选中，则仅禁用一个。

I want it so that when the check box is checked both radio buttons are enabled.我想要它，以便在选中复选框时启用两个单选按钮。 and when unchecked both radio buttons are disabled.未选中时，两个单选按钮都被禁用。

no Jquery, please没有Jquery，请

var sipch = document.querySelector("input[name=sip]");
sipch.addEventListener("change", function (event) {
    if (event.currentTarget.checked) {
        document.querySelector("input[name=protocol]").removeAttribute("disabled");
    } else {
        document.querySelector("input[name=protocol]").setAttribute("disabled", "disabled");
    }
});

Yo need to use querySelectorAll and then loop through the results, disabling/enabling each of them:你需要使用 querySelectorAll 然后遍历结果，禁用/启用它们中的每一个：

  if (event.currentTarget.checked) {
    document.querySelectorAll('input[name=protocol]')
        .forEach((elem) => elem.removeAttribute('disabled'));
  } else {
    document.querySelectorAll('input[name=protocol]')
        .forEach((elem) => elem.setAttribute('disabled', 'disabled'));
  }
