Local storage Note

JavaScript local storage notes

This code demonstrates how to use JavaScript to operate local storage, save and display text content.

JavaScript code:

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;
          }
        

HTML:

`; } };

Copy after login

This code uses a clearer code format, and some statements are slightly modified, such as changing == to === to make the code more standardized. The HTML part has been embedded in the iframe and no additional modification is required. The CSS style code has also been standardized and typed to make it easier to read.
