本地存储注意事项

JavaScript本地存储笔记

这段代码演示了如何使用JavaScript操作本地存储，保存和显示文本内容。

JavaScript代码：

<code class="language-javascript">let title = document.getElementById('title');
let text = document.getElementById('body');
let saveBtn = document.getElementById('save');
let display = document.getElementById('display');
let pst = document.getElementById('pst');
let clr = document.getElementById('clr');

saveBtn.onclick = function() {
  if (text.value === '') {
    alert('正文内容不能为空！');
  } else {
    pst.innerHTML += `
      <div>
        <p>CSS:</p>
        <pre class="brush:php;toolbar:false">
          #display {
            border: 4px solid;
          }
          #saver {
            border: 2px solid;
          }
          #clr {
            margin: 5%;
          }
          #editor {
            box-shadow: 0 0 3px red;
          }
          #editor input {
            width: 80%;
            box-shadow: 0 2px;
            color: #fff;
            -webkit-text-stroke: 1px #111;
          }
          #editor textarea {
            width: 80%;
            display: block;
            margin: 5% 2px 2px 9%;
            box-shadow: 0 0 3px;
            text-align: center;
          }
          #editor button, #display button {
            background: conic-gradient(navy, #44f);
            border-radius: 10px;
            border: 4px solid #0f07f0;
            width: 80%;
            font-size: 24px;
            color: white;
            -webkit-text-stroke: 2px red;
            font-weight: 800;
            text-transform: uppercase;
          }
