You can just set the disabledpropertyto falsein JavaScript, like this:

您可以只设置disabled属性false在JavaScript中,像这样的:

document.getElementById("myId").disabled = false;

var e = document.getElementById("someElement");
e.removeAttribute("disabled");

and disable again,

并再次禁用,

e.setAttribute('disabled','disabled');
