echarts定时渲染内存溢出问题处理(echarts渲染刷新导致浏览器卡)

echarts定时渲染地图出现浏览器内存溢出问题(echarts渲染刷新导致浏览器卡)

 

 

 

处理方式:

1)将定时变化的option内容单独提取定时刷新

2)先setOption数据后再clear(),之后再次setOption()

例如:

function Z(data)
{

    var x =  119.557082;
    var y = 26.659241;
    var zoom =  14;
    var points = data || [[]]
         var chart = echarts.init(document.getElementById("box"));
       chart.setOption({bmap:[{
            center: [x,y],
            zoom: zoom}],
            
            series: [{
            type: 'heatmap',
            coordinateSystem: 'bmap',
            data: points,
            pointSize: 5,
            blurSize: 6
        }]
            },{notMerge: false, lazyUpdate: false, silent:false});
chart.clear(); chart.setOption({bmap:[{ center: [x,y], zoom: zoom}], series: [{ type:
'heatmap', coordinateSystem: 'bmap', data: points, pointSize: 5, blurSize: 6 }] },{notMerge: false, lazyUpdate: false, silent:false}); }

 

参考

 注:可以尝试隔一段时间  【刷新】一次浏览器,由于是谷歌浏览器(没找到清除内存的JS)
