Question

我正在使用swal（http://t4t5.github.io/sweetalert）从用户点击某些内容时获取一些数据。我想从我正在调用swal的函数中返回它。换句话说，对于下面的示例，我想将labels中的项目文本设置为输入值。问题是它似乎在swal关闭/输入数据之前返回：

.on('dblclick', function(l) {
  labels.text(function (e) {  
     return swal({   
      title: "Edit label"
    },
      function(inputValue){  
      if(inputValue) {
        return inputValue
      }
    });
   })
});

普通prompt alert正在阻止，所以可以这样做，swal可以这样做吗？

虽然您无法使用Sweet Alerts阻止功能，但您可以使用其回调功能来触发任何需要首先解除警报的代码。这些例子有一些例子。例如，假设您有“是/否”样式警报，则会出现文件删除示例。

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){
  //The callback will only fire on cancel if the callback function accepts an
  //argument. So, if the first line were 'function () {' with no argument, clicking
  //cancel would not fire the callback.
  if (isConfirm) {
    swal("Deleted!", "Your imaginary file has been deleted.", "success");
  } else {
    swal("Cancelled", "Your imaginary file is safe :)", "error");
  }
});

或AJAX示例：

swal({
  title: "Ajax request example",
  text: "Submit to run ajax request",
  type: "info",
  showCancelButton: true,
  closeOnConfirm: false,
  showLoaderOnConfirm: true,
},
function(){
  setTimeout(function(){
    swal("Ajax request finished!");
  }, 2000);
});

在这两种方法中，在与警报交互之前不会触发回调，并且调用的结果作为参数传递给回调。

所以说你需要等到有人点击好。

swal({
  title: "Delete your account?",
  text: "Clicking on continue will permanently delete your account.",
  type: "warning",
  confirmButtonText: "Continue",
  closeOnConfirm: false
}, function () {
  swal("Deleted account", "We'll miss you!", "success");
});

注意：如果您在回调中显示后续警报，则closeOnConfirm / closeOnCancel只需false。如果它设置为true，它将在向用户显示之前关闭第二个警报。但是，如果您正在执行非swal相关的操作，并且您没有关闭它，它将无限期地保持打开状态。

swal({
  title: "Delete your account?",
  text: "Clicking on continue will permanently delete your account.",
  type: "warning",
  confirmButtonText: "Continue"
}, function () {
  console.log("This still shows!")
});

如果您希望警报在您执行非swal相关操作时保持打开状态，则应在代码末尾调用swal.close()。

swal({
  title: "Delete your account?",
  text: "Clicking on continue will permanently delete your account.",
  type: "warning",
  confirmButtonText: "Continue",
  closeOnConfirm: false
}, function () {
  console.log("This still shows!");
  setTimeout(function () {
    // This will close the alert 500ms after the callback fires.
    swal.close();
  }, 500);
});

不，它无法创建等待用户输入的阻止代码。只有JS已经提供的方式：提示，警报等。只需从回调中运行所需的代码。
