Confirm dialog box on delete button
提问by FluxEngine
I am working with an app using Angular.
我正在使用 Angular 使用应用程序。
I currently have a delete button, that has a confirmation attached to onClick()
我目前有一个删除按钮，上面附有确认 onClick()
<a class="delete button" href="#" onClick="return confirm('Are you absolutely sure you want to delete?')" ng-click="remove_user(user, $event)" ></a>
The problem is when the confirmation pops up, both "OK' and "Cancel" delete the item, what am I missing to get "Cancel" to simply cancel?
问题是当确认弹出时，“确定”和“取消”都删除了该项目，我错过了什么才能让“取消”简单地取消？

Maybe just using the angular click handler and doing the confirm logic there is worth a try.
也许只是使用角度点击处理程序并执行确认逻辑值得一试。
function FooController($scope, $window) {
$scope.removeUser = function() {
var deleteUser = $window.confirm('Are you absolutely sure you want to delete?');
if (deleteUser) {
$window.alert('Going to delete the user');
}
}
}
function FooController($scope, $window) {
$scope.removeUser = function() {
var deleteUser = $window.confirm('Are you absolutely sure you want to delete?');
if (deleteUser) {
$window.alert('Going to delete the user');
}
}

This is a little late but for future reader, like me 15 minutes ago:
这有点晚了，但对于未来的读者来说，就像 15 分钟前的我一样：
The "angular way" will be to create a directive as suggested here:
“角度方式”将按照此处的建议创建指令：
'use strict';
angular.module('confirm', [])
.directive('confirm', [function () {
return {
priority: 100,
restrict: 'A',
link: {
pre: function (scope, element, attrs) {
var msg = attrs.confirm || "Are you sure?";
element.bind('click', function (event) {
if (!confirm(msg)) {
event.stopImmediatePropagation();
event.preventDefault;
}
});
}
}
};
}]);
Usage:
用法：
<button ng-click="save()" confirm="Save Changes?">Save</button>

If you are using bootstrap for UI, I'd recommend using angular-dialog-service. Once you include the module dependencies, you can confirm it like this.
如果您使用UI引导程序，我建议使用angular-dialog-service。包含模块依赖项后，您可以像这样确认。
function FooController($scope, $dialogs)
{
$scope.removeUser = function() {
var dlg = dialogs.confirm('Please Confirm', 'Are you absolutely sure you want to delete?');
dlg.result.then(function () {
console.log("User has confirmed");//do something when user confirms
},function(){
console.log("User has cancelled");//do something when user cancels. Can omit the 2nd function if no handling is required
});
}
}
See this examplefor more details.

Just replace the onclick methods like below and it will work.
只需替换如下所示的 onclick 方法即可。
onclick="javascript:return confirm('Are you absolutely sure you want to delete?')"
回答by Chris Ciollaro
<a class="delete button" href="#" onClick="return false" ng-click="if(confirm('Are you absolutely sure you want to delete?')){remove_user(user, $event);}" ></a>
Try this? I think it has to do with the fact that you're stopping the default "onclick" listener but not affecting the "ng-click" listener. Instead I moved the confirm logic into the "ng-click" listener and "return false" onclick because you don't want the link to take you away.
尝试这个？我认为这与您停止默认的“onclick”侦听器但不影响“ng-click”侦听器的事实有关。相反，我将确认逻辑移到“ng-click”侦听器中，并在单击时“返回 false”，因为您不希望链接将您带走。

Well I would create a function that will tick a global variable and check it on submit
好吧，我会创建一个函数来勾选一个全局变量并在提交时检查它
<form onsubmit='check_delete()'
<input type='submit' onclick='set_delete()'
Javascript
Javascript
function set_delete(){delete_flag = 1 ;} // this is a global var set by default to 0
function check_delete(){if(delete_flag == 1) confirm(''sure?);}
