<template>
  <div>
    input: <el-input style="width: 200px;" v-model="inttest"></el-input>
    <el-button @click="runall">runall</el-button>
    <p>{{Reg1}}</p>
    <p>输入：{{inttest}}</p>
    <p>test = {{test1}}
      <el-button @click="checkTest">checkTest</el-button>
      <b style="color: #2276d2;">&nbsp; test判断是否匹配，返回值为true或者false</b>
    </p>
    <p>match = {{test2}}
      <el-button @click="checkMatch">checkMatch</el-button>
      <b style="color: #2276d2;">&nbsp; match取出匹配的字段</b>
    </p>
    <p>search = {{test3}}
      <el-button @click="checkSearch">checkSearch</el-button>
      <b style="color: #2276d2;">&nbsp; search() 方法用于检索字符串中指定的子字符串，或检索与正则表达式相匹配的子字符串，并返回子串的起始位置。</b>
    </p>
    <p>replace = {{test4}}
      <el-button @click="checkReplace">checkReplace</el-button>
      <b style="color: #2276d2;">&nbsp; replace() 方法 用于在字符串中用一些字符替换另一些字符，或替换一个与正则表达式匹配的子串。</b>
    </p>
    <p>exec = {{test5}}
      <el-button @click="checkExec">checkExec</el-button>
      <b style="color: #2276d2;">&nbsp; exec() 方法用于检索字符串中的正则表达式的匹配。 该函数返回一个数组，其中存放匹配的结果。如果未找到匹配，则返回值为 null。</b>
