我正在尝试将我的JavaScript confirm()
操作升级为使用SweetAlert。目前,我的代码是这样的:
<a href="/delete.php?id=100" onClick="return confirm('Are you sure ?');" >Delete</a>
这会在导航到删除页面之前等待用户确认。我想使用SweetAlert中的此示例要求用户在删除之前进行确认:
swal({
title: "Are you sure?",
text: "You will not be able to recover this imaginary file!",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "Yes, delete it!",
cancelButtonText: "No, cancel plx!",
closeOnConfirm: false,
closeOnCancel: false
},
function(isConfirm){
if (isConfirm) {
swal("Deleted!", "Your imaginary file has been deleted.", "success");
}
else {
swal("Cancelled", "Your imaginary file is safe :)", "error");
}
});
我尝试过的一切都失败了。当显示第一个警报时,页面前进,删除了该项目并刷新,甚至在用户单击警报按钮之前。如何使页面等待用户输入?
任何帮助将不胜感激。
您不能将其用作confirm
的替代产品。 confirm
阻塞执行的单个线程,直到确认对话框为止,您无法与基于JavaScript / DOM的对话框产生相同的行为。
您需要在警报框成功回调中向/delete.php?id=100
发出请求。
而不是...
swal("Deleted!", "Your imaginary file has been deleted.", "success");
您需要
<a href="#">Delete<a>
...
$.post('/delete.php?id=100').then(function () {
swal("Deleted!", "Your imaginary file has been deleted.", "success");
});
您还必须将您的delete.php
修复为仅接受POST
请求。允许GET
请求删除资源是一个巨大的问题。 Google或任何其他搜寻器第一次找到您的页面时,它将查看文档中每个链接的href
,并关注每个链接,删除所有内容。它们不会被confirm
框阻止,因为它们(除了Google之外)可能不会评估任何JavaScript。
您可以这样操作。
HTML:
<a href="/delete.php?id=100" class="confirmation" >Delete</a>
JS:
$('.confirmation').click(function (e) {
var href = $(this).attr('href');
swal({
title: "Are you sure?",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "Yes, delete it!",
cancelButtonText: "No, cancel plx!",
closeOnConfirm: true,
closeOnCancel: true
},
function (isConfirm) {
if (isConfirm) {
window.location.href = href;
}
});
return false;
});
似乎是一个hack,但对我有用。
$('.delete').click(function () {
var id = this.id;
swal({
title: "Are you sure?",
text: "Your will not be able to recover this post!",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "Yes, delete it!",
closeOnConfirm: false
},
function(){
alert(id);
});
});
<a id="<?php echo $row->id_portfolio ?>" class=" delete">
这是Angular指令中的一个示例(因为SweetAlert是通过angular指令包装器提供的)。这是在JavaScript中执行此操作的一种“优雅”方法。在click事件上,有一个e.stopImmediatePropagation(),然后,如果用户确认,它将评估“ ng-click”功能。 (请注意scope。$ eval不是JavaScript eval())。
标记:<i class="fa fa-times" ng-click="removeSubstep(step, substep)" confirm-click="Are you sure you want to delete a widget?"></i>
简单的“确认点击”指令:
/**
* Confirm click, e.g. <a ng-click="someAction()" confirm-click="Are you sure you want to do some action?">
*/
angular.module('myApp.directives').directive('confirmClick', [
'SweetAlert',
function (SweetAlert) {
return {
priority: -1,
restrict: 'A',
link: function (scope, element, attrs) {
element.bind('click', function (e) {
e.stopImmediatePropagation();
e.preventDefault();
var message = attrs.confirmClick || 'Are you sure you want to continue?';
SweetAlert.swal({
title: message,
type: 'warning',
showCancelButton: true,
closeOnConfirm: true,
closeOnCancel: true
}, function (isConfirm) {
if (isConfirm) {
if(attrs.ngClick) {
scope.$eval(attrs.ngClick);
}
} else {
// Cancelled
}
});
});
}
}
}
]);
