我写了以下代码,我想在"取消"按钮下调用代码:
vm.saveGroup = function(){
SweetAlert.swal({
title: "Name this Device Group",
text: "Please provide a name that you want your device group to be saved under. Also, make sure that you already specified all needed filters before you save the list.",
type: "input",
showCancelButton: true,
closeOnConfirm: false,
showLoaderOnConfirm: true,
inputPlaceholder: "Device Group name"
},
function(inputValue){
if (inputValue === false) {
return false;
}
if (inputValue === "") {
/*eslint-disable */
swal.showInputError("You need to write something!");
/*eslint-enable */
return false;
}
deviceGroupsFactory.saveGroup(inputValue, vm.filterOutput)
.then(function(response){
if (response.status == 200){
SweetAlert.swal("Device Group saved!", "You should now see your device group on the list.", "success");
$state.go('main.template.devices.groups');
}
else {
SweetAlert.swal("Error!", response.statusText, "error");
console.log('xxx');
}
});
});
}
但我不能调用"取消点击"。我一直在文档中寻找,但找不到解决方案。
您向swal构造函数传递了太多参数。它只需要两个:
swal(选项,回调)
- 选项:用于设计警报的属性
- 回调:管理事件的回调函数
使用简单确认时,回调仅接收一个指示用户选择的参数:
- 真:确认
- 错误:取消
使用输入框,您将收到用户的输入字符串作为参数。
当您将输入框合并在一起并确认时,您可能会收到:
- 输入字符串值:当用户按"确认"时
- 错误:当用户按"取消"时
因此,您必须使用严格相等比较才能知道用户是否按下了取消或已在输入框中插入了字符串false
。
请参阅以下简单示例:
swal({
title: "Are you sure?",
text: "Press CANCEL, please!",
type: "input",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "CONFIRM",
cancelButtonText: "CANCEL",
closeOnConfirm: false,
closeOnCancel: false
},
function(inputValue){
//Use the "Strict Equality Comparison" to accept the user's input "false" as string)
if (inputValue===false) {
swal("Well done!");
console.log("Do here everything you want");
} else {
swal("Oh no...","press CANCEL please!");
console.log("The user says: ", inputValue);
}
});

我希望它对你有帮助,再见。
你也可以使用 .then 来实现
promise我给你一个例子,这将在按下按钮后执行
swal( 'Error!',valido.msj,'error').then((e)=>{
if( valido.msj=="Enlace de botón No Válido" ){
document.getElementById('link_btn_barra').focus();
}
});
