背景:

有时候我们需要将json数据直接显示在页面上(比如在做一个接口测试的项目,需要将接口返回的结果直接展示),但是如果直接显示字符串,不方便查看。需要格式化一下。

解决方案:

其实JSON.stringify本身就可以将JSON格式化,具体的用法是:

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

如果想要效果更好看,还要加上格式化的代码和样式:

js代码:

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;;
    });
}

样式代码:

<style>
    pre {outline: 1px solid #ccc; padding: 5px; margin: 5px; }
    .string { color: green; }
    .number { color: darkorange; }
    .boolean { color: blue; }
    .null { color: magenta; }
    .key { color: red; }
</style>

html代码:

<pre id="result">

调用代码:

$(&#39;#result&#39;).html(syntaxHighlight(res));
