ng-click 上的确认对话框 - AngularJS [英] Confirmation dialog on ng-click - AngularJS

问题描述

我正在尝试使用自定义 angularjs 指令在 ng-click 上设置确认对话框:

I am trying to setup a confirmation dialog on an ng-click using a custom angularjs directive:

app.directive('ngConfirmClick', [
    function(){
        return {
            priority: 1,
            terminal: true,
            link: function (scope, element, attr) {
                var msg = attr.ngConfirmClick || "Are you sure?";
                var clickAction = attr.ngClick;
                element.bind('click',function (event) {
                    if ( window.confirm(msg) ) {
                        scope.$eval(clickAction)
                    }
                });
            }
        };
}])

这很好用，但不幸的是，使用我的指令的标签内的表达式不会被评估:

This works great but unfortunately, expressions inside the tag using my directive are not evaluated:

<button ng-click="sayHi()" ng-confirm-click="Would you like to say hi?">Say hi to {{ name }}</button>

(在这种情况下不评估名称).这似乎是由于我的指令的终端参数.你有任何解决方法的想法吗?

(name is not evaluated is this case). It seems to be due to the terminal parameter of my directive. Do you have any ideas of workaround?

推荐答案

如果您不介意不使用 ng-click，它可以正常工作.您可以将其重命名为其他名称并仍然读取该属性，同时避免点击处理程序被触发两次目前存在的问题.

If you don't mind not using ng-click, it works OK. You can just rename it to something else and still read the attribute, while avoiding the click handler being triggered twice problem there is at the moment.

我认为问题在于 terminal 指示其他指令不要运行.{{ }} 的数据绑定只是 ng-bind 指令的别名，大概被 terminal 取消了.

I think the problem is terminal instructs other directives not to run. Data-binding with {{ }} is just an alias for the ng-bind directive, which is presumably cancelled by terminal.
