幸运28源码-出售使用Echarts实现地图下钻

#2将地图实现写成方法幸运28源码-出售Q2152876294 论坛：diguaym.com
*1）原代码：

var option = {
    backgroundColor: '#FFFFFF',
    title: {
        text: '全国地图',
        subtext: '纯属虚构',
        x:'center'
    },
    tooltip : {
        trigger: 'item'
    },
    visualMap: {
        show : false,
        x: 'left',
        y: 'bottom',
        splitList: [ 
            {start: 500, end:600},{start: 400, end: 500},
            {start: 300, end: 400},{start: 200, end: 300},
            {start: 100, end: 200},{start: 0, end: 100},
        ],
        color: ['#66CC33', '#00FF00', '#66FF33','#339900', '#33CC00', '#00CC00']
    },
    series: [{
        name: '随机数据',
        type: 'map',
        mapType: 'china', 
        roam: true,
        label: {
            normal: {
                show: false
            },
            emphasis: {
                show: false
            }
        },
        data:mydata
    }]
};
var chart = echarts.init(document.getElementById('main'));

chart.setOption(option);
*2）改写后代码（将代码放到方法里，并将mapType和data作为外部参数）：
function drawMap(darwMapType, data) {
var option = {
backgroundColor: '#FFFFFF',
title: {
text: '全国地图',
subtext: '纯属虚构',
x:'center'
},
tooltip : {
trigger: 'item'
},
visualMap: {
show : false,
x: 'left',
y: 'bottom',
splitList: [
{start: 500, end:600},{start: 400, end: 500},
{start: 300, end: 400},{start: 200, end: 300},
{start: 100, end: 200},{start: 0, end: 100},
],
color: ['#16CC33', '#10FF00', '#16FF33','#139900', '#13CC00', '#10CC00']
},
series: [{
name: '随机数据',
type: 'map',
mapType: darwMapType,
roam: true,
label: {
normal: {
show: false
},
emphasis: {
show: false
}
},
data:data
}]
};
echarts.dispose(document.getElementById('main'));
var chart = echarts.init(document.getElementById('main'));
chart.setOption(option);
}

*3）改写方法后在onload进行调用
window.onload = function() {
drawMap('china', mydata);
}

#3实现地图下钻
*1）使用单击、双击（移动端不支持）或者长按触发实现地图下钻，此处使用双击（暂不作多次下钻和返回函数编写）

chart.on("dblclick", function(param) {
drawMap(param.name, guangdongData);
});
