新手关于echarts异步调用问题请教。

Question

我异步处理这个数据并显示出来，把data0的数据放到文件abc.json.这个怎么处理，还有调用异步的时候是带name:'MA5'这些放异步里面吗？还是可以先加载。异步只要填入数据就可以了。自己整了很久没解决。只能提问了。另外代码可以放在XXX.JS里面吗？我放在XXX.JS里面用加载的时候，第一句varmyChart=echarts.init(document.getElementById('main'),'light');就报错是为什么。恳请批点。非常感谢官方源码。varupColor='#ec0000';varupBorderColor='#8A0000';vardownColor='#00da3c';vardownBorderColor='#008F28';//数据意义：开盘(open)，收盘(close)，最低(lowest)，最高(highest)vardata0=splitData([['2013/1/24',2320.26,2320.26,2287.3,2362.94],['2013/1/25',2300,2291.3,2288.26,2308.38],['2013/1/28',2295.35,2346.5,2295.35,2346.92],['2013/1/29',2347.22,2358.98,2337.35,2363.8],['2013/1/30',2360.75,2382.48,2347.89,2383.76],['2013/1/31',2383.43,2385.42,2371.23,2391.82],['2013/2/1',2377.41,2419.02,2369.57,2421.15],['2013/2/4',2425.92,2428.15,2417.58,2440.38],['2013/2/5',2411,2433.13,2403.3,2437.42],['2013/2/6',2432.68,2434.48,2427.7,2441.73],['2013/2/7',2430.69,2418.53,2394.22,2433.89],['2013/2/8',2416.62,2432.4,2414.4,2443.03],['2013/2/18',2441.91,2421.56,2415.43,2444.8],['2013/2/19',2420.26,2382.91,2373.53,2427.07],['2013/2/20',2383.49,2397.18,2370.61,2397.94],['2013/2/21',2378.82,2325.95,2309.17,2378.82],['2013/2/22',2322.94,2314.16,2308.76,2330.88],['2013/2/25',2320.62,2325.82,2315.01,2338.78],['2013/2/26',2313.74,2293.34,2289.89,2340.71],['2013/2/27',2297.77,2313.22,2292.03,2324.63],['2013/2/28',2322.32,2365.59,2308.92,2366.16],['2013/3/1',2364.54,2359.51,2330.86,2369.65],['2013/3/4',2332.08,2273.4,2259.25,2333.54],['2013/3/5',2274.81,2326.31,2270.1,2328.14],['2013/3/6',2333.61,2347.18,2321.6,2351.44],['2013/3/7',2340.44,2324.29,2304.27,2352.02],['2013/3/8',2326.42,2318.61,2314.59,2333.67],['2013/3/11',2314.68,2310.59,2296.58,2320.96],['2013/3/12',2309.16,2286.6,2264.83,2333.29],['2013/3/13',2282.17,2263.97,2253.25,2286.33],['2013/3/14',2255.77,2270.28,2253.31,2276.22],['2013/3/15',2269.31,2278.4,2250,2312.08],['2013/3/18',2267.29,2240.02,2239.21,2276.05],['2013/3/19',2244.26,2257.43,2232.02,2261.31],['2013/3/20',2257.74,2317.37,2257.42,2317.86],['2013/3/21',2318.21,2324.24,2311.6,2330.81],['2013/3/22',2321.4,2328.28,2314.97,2332],['2013/3/25',2334.74,2326.72,2319.91,2344.89],['2013/3/26',2318.58,2297.67,2281.12,2319.99],['2013/3/27',2299.38,2301.26,2289,2323.48],['2013/3/28',2273.55,2236.3,2232.91,2273.55],['2013/3/29',2238.49,2236.62,2228.81,2246.87],['2013/4/1',2229.46,2234.4,2227.31,2243.95],['2013/4/2',2234.9,2227.74,2220.44,2253.42],['2013/4/3',2232.69,2225.29,2217.25,2241.34],['2013/4/8',2196.24,2211.59,2180.67,2212.59],['2013/4/9',2215.47,2225.77,2215.47,2234.73],['2013/4/10',2224.93,2226.13,2212.56,2233.04],['2013/4/11',2236.98,2219.55,2217.26,2242.48],['2013/4/12',2218.09,2206.78,2204.44,2226.26],['2013/4/15',2199.91,2181.94,2177.39,2204.99],['2013/4/16',2169.63,2194.85,2165.78,2196.43],['2013/4/17',2195.03,2193.8,2178.47,2197.51],['2013/4/18',2181.82,2197.6,2175.44,2206.03],['2013/4/19',2201.12,2244.64,2200.58,2250.11],['2013/4/22',2236.4,2242.17,2232.26,2245.12],['2013/4/23',2242.62,2184.54,2182.81,2242.62],['2013/4/24',2187.35,2218.32,2184.11,2226.12],['2013/4/25',2213.19,2199.31,2191.85,2224.63],['2013/4/26',2203.89,2177.91,2173.86,2210.58],['2013/5/2',2170.78,2174.12,2161.14,2179.65],['2013/5/3',2179.05,2205.5,2179.05,2222.81],['2013/5/6',2212.5,2231.17,2212.5,2236.07],['2013/5/7',2227.86,2235.57,2219.44,2240.26],['2013/5/8',2242.39,2246.3,2235.42,2255.21],['2013/5/9',2246.96,2232.97,2221.38,2247.86],['2013/5/10',2228.82,2246.83,2225.81,2247.67],['2013/5/13',2247.68,2241.92,2231.36,2250.85],['2013/5/14',2238.9,2217.01,2205.87,2239.93],['2013/5/15',2217.09,2224.8,2213.58,2225.19],['2013/5/16',2221.34,2251.81,2210.77,2252.87],['2013/5/17',2249.81,2282.87,2248.41,2288.09],['2013/5/20',2286.33,2299.99,2281.9,2309.39],['2013/5/21',2297.11,2305.11,2290.12,2305.3],['2013/5/22',2303.75,2302.4,2292.43,2314.18],['2013/5/23',2293.81,2275.67,2274.1,2304.95],['2013/5/24',2281.45,2288.53,2270.25,2292.59],['2013/5/27',2286.66,2293.08,2283.94,2301.7],['2013/5/28',2293.4,2321.32,2281.47,2322.1],['2013/5/29',2323.54,2324.02,2321.17,2334.33],['2013/5/30',2316.25,2317.75,2310.49,2325.72],['2013/5/31',2320.74,2300.59,2299.37,2325.53],['2013/6/3',2300.21,2299.25,2294.11,2313.43],['2013/6/4',2297.1,2272.42,2264.76,2297.1],['2013/6/5',2270.71,2270.93,2260.87,2276.86],['2013/6/6',2264.43,2242.11,2240.07,2266.69],['2013/6/7',2242.26,2210.9,2205.07,2250.63],['2013/6/13',2190.1,2148.35,2126.22,2190.1]]);functionsplitData(rawData){varcategoryData=[];varvalues=[]for(vari=0;i

Answer 1

varmyChart=echarts.init(document.getElementById('main'),'light');报错一般是因为在页面上没有找到id='main'的元素。异步调用的时候，可以这样操作：
varresult=[];
varoption={
...,
series:[
{
...,
data:result
}
]
};
asyncres.get(function(data){
result=data;
myChart.setOption(option,true);
});
先声明一个空数组varresult=[]，在option中直接给series写上data:result。待异步调用结束时，给result赋值，然后再次执行myChart.setOption(option,true);
