Question

我需要以某种方式检查按钮是否能够被按下。我正在使用“启用”，这两个结果（可以按下的按钮/不能按下的按钮）均设置为真实值。

我想获取属性/属性，但不知道应该从DOM中确切获取什么：

<div class="w-90 text-right m-auto">

您可以看到在禁用的按钮中有禁用的单词按钮tabindex =“ -1”，并且在可以按下按钮时按钮tabindex =“ 0”。

Answer 1

disabled属性返回bool，您可以检查GetAttribute()是否返回true。

string disabledAttribute = element.GetAttribute("disabled");
if (disabledAttribute)
{
    // element has "disabled" attribute
}
