jquery合并两个对象

Object.assign(target,source,souce...)

$.extend( target [, object1 ] [, objectN ] )

lodash.assign(target,source)

for (key in source) {
   // if (source.hasOwnProperty(key)) {
   // if (source.hasOwnProperty.call(source, key)) {
   if (Object.hasOwnProperty.call(source, key)) {
      target[key] = source[key]
    }
}
