如何在指令中设置 ng-disabled [英] How to set ng-disabled inside directive

问题描述

我的指令有

link: function ($scope, $elm, $attrs) {
    var status = $scope.item.status
    if (status) {
        var statusName = status.name,
            item = $scope.item;
        if (statusName === 'USED') {
            $attrs.$set('ng-disabled', true); // this doesn't work
        } else {
            $elm.attr('ng-disabled', false);
        }
    }
}

所以，我的问题是:

如何使用此指令将 ng-disabled 应用到元素?

How to apply ng-disabled to element with this directive?

推荐答案

您可以将 ng-disabled 设置为范围变量，例如:

You would set ng-disabled to a scope variable, ex:

<input ng-disabled="isDisabled" />

然后在你的指令中你可以设置那个变量:

And then inside your directive you can set that variable:

$scope.isDisabled = true;
