这次给大家带来html直接显示JSON方法详解,在html显示JSON的注意事项有哪些,下面就是实战案例,一起来看一下。

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
Copy after login

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, '&').replace(/</g, &#39;<&#39;).replace(/>/g, '>');
    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 = '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="&#39; + cls + &#39;">' + match + '</span>';
    });
}
Copy after login

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>
Copy after login

html代码:

<pre id="result">
Copy after login

调用代码:

$('#result').html(syntaxHighlight(res));
Copy after login

效果:
