Recursively check if a configuration item has changed and replace it

介绍

1. When the configuration item has the original configuration item,I don't want to change other configurations and can change the proposed configuration.参考 echarts 的配置
2. 本文以递归的方式,实现了对象format check and replace,Arrays can be added according to the rules;
3. The values ​​that support the same attribute are based on the incoming attribute value;Properties that are not in the original configuration are added directly（当前级）;
4. According to the third point can be supported echarts、Secondary packaging configuration such as maps.

实现代码

const configSet = (config, eCData = echartsComponent.data) => {
    
  if (!config) return;
  Object.keys(eCData).forEach(key => {
    
    if (!(key in config)) return
    if (Object.prototype.toString.call(config[key]) === '[object Object]') return configSet(config[key], eCData[key])
    eCData[key] = config[key]
  })
  Object.keys(config).forEach(key => {
    
    if (!(key in eCData)) eCData[key] = config[key]
  })
}
