对url参数进行解码

很久没使用原生js了，写的一塌糊涂。但是能用。

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>url参数解码</title>
    <style>
      * {
        padding: 0;
        margin: 0;
      }
      .container {
        display: flex;
        justify-content: center;
        flex-direction: column;
        /* align-items: center; */
        width: 100%;
        height: 100vh;
      }
      .content {
        display: flex;
        align-items: center;
      }
      textarea {
        flex: 3;
        height: 30vh;
        width: 100%;
      }
      button {
        flex: 1;

        height: 30vh;
      }
    </style>
  </head>
  <body>
    <div class="container">
      <div class="content">
        <textarea id="textarea" placeholder="请输入url" type="text"></textarea>
        <button onclick="handleClick()" id="jiema">解码</button>
      </div>
      <div class="result">
        <ul id="result"></ul>
      </div>
    </div>
    <script>
      const jiema = document.getElementById("jiema");
      const textarea = document.getElementById("textarea");
      const result = document.getElementById("result");
      function splits(data, node) {
        if (!data) {
          alert("未解析到参数");
          return false;
        }
        const value = data.split(node);
        return value;
      }
      const handleJiema = function (value) {
        let arr = [];
        let arr1 = value.split("?")[1];
        let arr2 = splits(arr1, "&");
        if (!arr2) {
          return;
        }
        for (const iterator of arr2) {
            arr.push(splits(iterator, "="))
            let node = document.createElement('li')
            let textNode = document.createTextNode(splits(iterator, "=").join('---'))
            node.appendChild(textNode)
            result.appendChild(node)
        }
      };
      const handleClick = function () {
        handleJiema(textarea.value);
      };
      //   jiema.click()
    </script>
  </body>
</html>
