在 Javascript 中运行函数后成功或错误 toast

Question

我有两个如下所示的函数：

function functionOne(par1, par2, par3) {
// this functions patches using an api, re-usable
}

function functionTwo(par2) {
functionOne(par1, par2, par3);
functionOne(par1, par2, par3);
functionOne(par1, par2, par3);
functionOne(par1, par2, par3);
}

这按预期工作，但如果用户按下按钮并且 functionTwo 成功运行或出现错误，我想给用户一些反馈。

我发现了这个：https://www.w3schools.com/howto/howto_js_snackbar.asp 这是我想要的，而不是弹出窗口，但是是否可以在成功或错误后显示它，如果可以，如何显示？谢谢！

Answer 1

看看下面的sn-p：

HTML 和 CSS 是从 W3C 示例中提取的代码。 JS 函数showToast() 是基于他们的示例，但采用带有默认值的可选参数并将该参数值附加到 toast。

我制作了一个 API (yourApiFuncton()) 调用的小例子来演示使用。

当然，这只是一个基本示例，您可以从那里开始工作以获得更好的东西。

function yourApiFunction(){
  
  //Do your api calls, the "error" variable is only set to demonstrate the use of the success/error message
  let error = false;
  
  if(error){
    showToast("Oh no...");
  }else{
      showToast("Hell yeah");
  }
}

function showToast(content = "Unknown error") { //You can change the default value
  // Get the snackbar DIV
  var x = document.getElementById("snackbar");
  
  //Change the text (not mandatory, but I think you might be willing to do it)
  x.innerHTML = content;

  // Add the "show" class to DIV
  x.className = "show";

  // After 3 seconds, remove the show class from DIV
  setTimeout(function(){ x.className = x.className.replace("show", ""); }, 3000);
}

//Simulating a call to your API
yourApiFunction();

/* The snackbar - position it at the bottom and in the middle of the screen */
#snackbar {
  visibility: hidden; /* Hidden by default. Visible on click */
  min-width: 250px; /* Set a default minimum width */
  margin-left: -125px; /* Divide value of min-width by 2 */
  background-color: #333; /* Black background color */
  color: #fff; /* White text color */
  text-align: center; /* Centered text */
  border-radius: 2px; /* Rounded borders */
  padding: 16px; /* Padding */
  position: fixed; /* Sit on top of the screen */
  z-index: 1; /* Add a z-index if needed */
  left: 50%; /* Center the snackbar */
  bottom: 30px; /* 30px from the bottom */
}

/* Show the snackbar when clicking on a button (class added with JavaScript) */
#snackbar.show {
  visibility: visible; /* Show the snackbar */
  /* Add animation: Take 0.5 seconds to fade in and out the snackbar.
  However, delay the fade out process for 2.5 seconds */
  -webkit-animation: fadein 0.5s, fadeout 0.5s 2.5s;
  animation: fadein 0.5s, fadeout 0.5s 2.5s;
}

/* Animations to fade the snackbar in and out */
@-webkit-keyframes fadein {
  from {bottom: 0; opacity: 0;}
  to {bottom: 30px; opacity: 1;}
}

@keyframes fadein {
  from {bottom: 0; opacity: 0;}
  to {bottom: 30px; opacity: 1;}
}

@-webkit-keyframes fadeout {
  from {bottom: 30px; opacity: 1;}
  to {bottom: 0; opacity: 0;}
}

@keyframes fadeout {
  from {bottom: 30px; opacity: 1;}
  to {bottom: 0; opacity: 0;}
}

<!-- The actual snackbar -->
<div id="snackbar">Some text some message..</div>

尝试使用ToastMaker 库。

$('#successbutton').click(() =>
  ToastMaker("Success", 5000, {
    styles: {
      backgroundColor: 'green'
    }
  })
);

$('#failbutton').click(() =>
  ToastMaker("Failure", 5000, {
    styles: {
      backgroundColor: 'red'
    }
  })
);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<link rel="stylesheet" type="text/css" href="https://unpkg.com/toastmaker/dist/toastmaker.min.css">

<script type="text/javascript" src="https://unpkg.com/toastmaker/dist/toastmaker.min.js"></script>


<button id="successbutton"> Success Toast</button>
<button id="failbutton"> Fail Toast</button>
