Question

如何在没有确认按钮的情况下使用sweetalert进行Ajax调用但仍显示加载gif？基本上我想在Ajax调用运行时显示加载gif。开箱即用的解决方案要求您在进行Ajax调用之前启用确认按钮。

以下显然不起作用：

window.swal({
    title: "Checking...",
    text: "Please wait",
    imageUrl: "images/ajaxloader.gif",
    showConfirmButton: false,
    allowOutsideClick: false
},
function () {
    $.getJSON('myurl').done(function (data) {
        swal("", "Good job!", "success");
    }).fail(function (jqXHR, textStatus, err) {
        swal("", "An error occurred",    "error");
    });
});

Answer 1

你不需要做任何特别的事情。只需在显示swal后进行ajax调用，并在完成ajax后再次调用swal。

window.swal({
  title: "Checking...",
  text: "Please wait",
  imageUrl: "images/ajaxloader.gif",
  showConfirmButton: false,
  allowOutsideClick: false
});

//using setTimeout to simulate ajax request
setTimeout(() => {
  window.swal({
    title: "Finished!",
    showConfirmButton: false,
    timer: 1000
  });
}, 2000);

基于Ozan's very helpful answer的实现示例：

使用vue-sweetalert2，VueJS 2和Axios，并内置加载程序动画：

  let self = this;
  this.$swal.fire({
    title: "Processing Request...",
    text: "Please wait",
    onBeforeOpen() {
      self.$swal.showLoading(); //Adds built in loader animation during modal open
    },
    onAfterClose() {
      self.$swal.hideLoading(); //might not be necessary
    },
    allowOutsideClick: false, //makes modal behave captively
    allowEscapeKey: false,
    allowEnterKey: false
  });

  axios
    .post(`/api/myapi`, {"fake": "fake"})
    .then(r => {
      this.$swal.update({
        title: "Finished",
        html: `Response data: ${r.data}`
      });
      this.$swal.hideLoading(); //Disables loader spinner, enables button
    })
    .catch(err => {
      this.$swal.update({
        title: "FAILED!",
        text: "Something went wrong - either try again or contact support."
      });
      this.$swal.showValidationMessage(`Request failed: ${err}`);
      this.$swal.hideLoading(); //Disables loader spinner, enables button
    })
