折腾：
期间，想要对于js中的数组：
去for循环，同时希望获取index
所以想到了：
js中是否有python中的，对于数组之类的enumerate
js enumerate
javascript – What is the ES6 equivalent of Python ‘enumerate’ for a sequence? – Stack Overflow
Array.prototype.entries()
Array.prototype.entries() – JavaScript | MDN
但是依旧不太好用：
for(let curIdx, curFunctionGroupName of functionGroupNames.entries()){
会报错。
所以继续搜：
js array entries example
JavaScript Array entries() Method
JavaScript ES6 — Learn Array.keys, Array.values, and Array.entries
Object.entries(user) = [ ["name","John"], ["age",30] ]
感觉应该写成：for中每个都是 keyValueList
Array.prototype.entries() – JavaScript | MDN
后来自己去回复了：
javascript – What is the ES6 equivalent of Python ‘enumerate’ for a sequence? – Stack Overflow
for(let curIndexValueList of someArray.entries()){
console.log("curIndexValueList=", curIndexValueList)
let curIndex = curIndexValueList[0]
let curValue = curIndexValueList[1]
console.log("curIndex=", curIndex, ", curValue=", curValue)
}
等价于python代码：
for curIndex, curValue in enumerate(someArray):
print("curIndex=%s, curValue=%s" % (curIndex, curValue))
}
【总结】
最后用代码：
if (functionGroupNames && functionGroupOwners && functionGroupIDs) {
let functionGroupInfoDictList = []
for(let curKeyValueList of functionGroupNames.entries()){
console.log("curKeyValueList=", curKeyValueList)
let curIdx = curKeyValueList[0]
let curGroupName = curKeyValueList[1]
console.log("curIdx=", curIdx, "curGroupName=", curGroupName)
let curGroupOwner = functionGroupOwners[curIdx]
let curGroupId = functionGroupIDs[curIdx]
console.log("curGroupOwner=", curGroupOwner, "curGroupId=", curGroupId)
let curGroupInfoDict = {
"groupId": curGroupId,
"groupName": curGroupName,
"groupOwnerName": curGroupOwner,
}
functionGroupInfoDictList.push(curGroupInfoDict)
}
console.log("functionGroupInfoDictList=", functionGroupInfoDictList)
}
核心部分是：
for(let curKeyValueList of functionGroupNames.entries()){
let curIdx = curKeyValueList[0]
let curGroupName = curKeyValueList[1]
效果是：
