vue.jsevent modifier

Below I will share with you a detailed explanation of the usage of the event modifier .self in vue.js. It has a good reference value and I hope it will be helpful to everyone.

.self can be understood as skipping bubbling events and capturing events. Only events that directly act on the element can be executed.

The code is as follows:

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>self</title>
 <script src="vue.js"></script>
 <!--&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;&#39;请自行引入vue.js-->
</head>
<style type="text/css">
 * {
  margin: 0 auto;
  text-align:center;
  line-height: 40px;
 }
 p {
  width: 100px;
 }
 #obj1 {
  background: deeppink;
 }
 #obj2 {
  background: pink;
 }
 #obj3 {
  background: hotpink;
 }
 #obj4 {
   background: #ff4225;
  }
</style>
<script src="vue.js"></script>
</head>
<body>
<!--点击obj4的时候会分别显示： obj4、 obj3、 obj1；
.self会监视事件是否是直接作用到obj2上，若不是，则冒泡跳过该元素，-->
<p id="content">
 <p id="obj1" v-on:click="doc">
  obj1
  <p id="obj2" v-on:click.self="doc">
   obj2
   <!--只有点击obj2才可以出发其点击事件。-->
   <p id="obj3" v-on:click="doc">
    obj3
    <p id="obj4" v-on:click="doc">
     obj4
    </p>
   </p>
  </p>
 </p>
</p>
<script type="text/javascript">
 var content = new Vue({
  el: "#content",
  data: {
   id: &#39;&#39;
  },
  methods: {
   doc: function () {
    this.id= event.currentTarget.id;
    alert(this.id)
   }
  }
 })
</script>
</body>
</html>

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
