看你的后台了，你想输出几条，就{"onlinetime":"2018-06-26 23:50:02","onlinenumber":262913705} ,这里循环几次

如果控制不了服务器想客户端js控制用这个

<script>
    var s = '[' + document.body.innerText.replace(/\s*,\s*$/, '') + ']';
    var arr = JSON.parse(s), pagesize = 4, current = 0, totalpage = Math.ceil(arr.length / pagesize);
    function getHtml(isPre) {
        if (isPre !== undefined) isPre ? current-- : current++;
        var s=JSON.stringify(arr.slice(current * pagesize, (current + 1) * pagesize - 1))
        if (totalpage > 1) {s+='<br>'
            if (current > 0) s += '<a href="javascript:getHtml(true)">上一页</a>　';
            if (current < totalpage-1) s += '<a href="javascript:getHtml(false)">下一页</a>　';
        }
        document.body.innerHTML = s;
    }
    getHtml()
</script>
</html>

试着写了一个js，

var rxt = /\{([^\}]+)\}/g; var str = document.body.innerHTML var arr = str.match(rxt) arr.pop() //显示条数 function showNum(start, count) { //start开始的条数 //count共显示几条 var html = "" var copyArr = arr.slice(0) var showArr = copyArr.splice(start,count) showArr.forEach(function(item){ html = html + item + "</br>" }) return html } document.write(showNum(0,3))

试着写了一个js，刚刚格式不对

 <script>
    var rxt = /\{([^\}]+)\}/g;
    var str = document.body.innerHTML 
    var arr = str.match(rxt)
    arr.pop()
    //显示条数
    function showNum(start, count) {
        //start开始的条数
        //count共显示几条
        var html = ""
        var copyArr = arr.slice(0)
        var showArr = copyArr.splice(start,count)
        showArr.forEach(function(item){
            html = html + item + "</br>"
        })
        return html
    }

    document.write(showNum(start, count))

</script>
