如何在页面显示json数据

Posted 2021-01-17 xieli26

1.方法:

syntaxHeightlight(json) {
  if (typeof json !== "string") {
    json = JSON.stringify(json, undefined, 2)
  }
  json = json.replace(/&/g, ‘&‘).replace(/</g, ‘<‘).replace(/>/g,
    ‘>‘);
  return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(s*:)?|(true|false|null)|-?d+(?:.d*)?(?:[eE][+-]?d+)?)/g, function (match) {
    var cls = ‘number‘;
    if (/^"/.test(match)) {
      if (/:$/.test(match)) {
        cls = ‘key‘;
      } else {
        cls = ‘string‘;
      }
    } else if (/true|false/.test(match)) {
      cls = ‘boolean‘;
    } else if (/null/.test(match)) {
      cls = ‘null‘;
    }
    return ‘<span class="‘ + cls + ‘">‘ + match + ‘</span>‘;
  });
}

　2.在html里面添加一个区域:

<pre id="result">
</pre>

3.调用该方法:

$(‘#result‘).html(syntaxHighlight(data));
