vue 中使用 tradingview

加载页面时初始化方法： mounted
可以在 mounted 方法中调用 methods 的中的方法
使用 data 中的数据时，在每个方法的开始推荐先定义 var that = this
现在还不明白开始时为什么执行两次 resolveSymbol 方法
不要纠结页面的数据怎么获取到某个方法中的，它自己就获取了。例如 resolveSymbol 方法，根据商品名称解析商品信息。你在输入框中输入某个商品时，值自动被 resolveSymbol 方法获取。
在 gerBar 方法中，执行回调函数的时候，eg： settimeout（callback， 1000）让其 1 秒后执行，因为若去后台获取数据采用 axios.post() 是异步的。
开始时执行顺序：
　　createChartData -> subscribeSymbol -> unsubscribeSymbol -> TradingView.onready -> onChartReady -> onReady(图表雏形) -> resolveSymbol -> getBar
切换商品时顺序：
　　searchSymbols -> resolveSymbol -> getBar
