大数据量学习:ajax获取数据后将数组重新分组后分批定时渲染的解决方案

ajax调用数据

    $.getJSON("data/yinzhou.json", "", function (res, status) {
        var data = res.features;
        // console.log(data);
        //分组渲染;
        if (status == "success") {
            arrChunk(data, 1);
        } else {
            console.log("Cann't GET Data.")
        }

    })

封装分组函数

    function arrChunk(data, chunk) {
        var result = [];
        //数组分组数量;
        var chunk = chunk;

        //执行数组分组;
        for (var i = 0, j = data.length; i
