JSONデータをHTMLで表示する方法

JSON.stringify(res, null, 2); //res是要JSON化的对象，2是spacing

function syntaxHighlight(json) {
    if (typeof json != 'string') {
        json = JSON.stringify(json, undefined, 2);
    }
    json = json.replace(/&/g, &#39;&&#39;).replace(/</g, &#39;<&#39;).replace(/>/g, &#39;>&#39;);
    return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g, function(match) {
        var cls = &#39;number&#39;;
        if (/^"/.test(match)) {
            if (/:$/.test(match)) {
                cls = &#39;key&#39;;
            } else {
                cls = &#39;string&#39;;
            }
        } else if (/true|false/.test(match)) {
            cls = &#39;boolean&#39;;
        } else if (/null/.test(match)) {
            cls = &#39;null&#39;;
        }
        return &#39;<span class="&#39; + cls + &#39;">&#39; + match + &#39;</span>&#39;;
    });
}
