asyncSettings.successMessage 进入 Sweet Alert

Question

我怎样才能把这个的成功信息变成甜蜜的警报？

asyncSettings.successMessage

可以只包含字符串而不包含函数吗？

    modalForm(this, {
      formURL: "/invite-user/"+$(this).data()['subscription'],
      asyncUpdate: true,
      asyncSettings: {
        closeOnSubmit: true,
        successMessage: asyncSuccessMessage,
        dataUrl: "{% url 'get_licenses' %}",
        dataElementId: "#subscription_wrapper",
        dataKey: "table",
        addModalFormFunction: reinitiateModalForms
      }
    })
