空元素被添加到Object [英] Empty element is added to Object

问题描述

我从 duplicates 数组创建了一个对象，并动态推送到它的元素。一切正常，除了我得到一个额外的空元素，我无法弄清楚为什么...

I create an object from duplicates array and I dynamically push to it elements. Everything works fine, excepting that I'm getting an additional empty element and I can't figure it out why...

这是我的代码：

for(i=0;i<duplicates.length; i++) {
  Logger.log(duplicates[i]);
  var request = {
    "name": duplicates[i].scope,
    "id": 3,
    "rules":[
      {
        "name": duplicates[i].scope + " " + "OP SDR Sync",
        "tags": [
          {
            "tagId": 1,
            "variables":[
              {
              }
            ],
            "condition": false,
          },
          {
            "tagId": 1,
            "condition": false,
          }
        ],
        "ruleSetId": 3,
      }
    ]
  }

  for(var j in duplicates[i].variable) {
    request.rules[0].tags[0].variables.push({
      "variable": duplicates[i].variable[j],
      "matchType": "Regex",
      "value": duplicates[i].scopeDef
    });
  }
}

以下是一个例子：

重复 = [
{scopeDef =。*，scope = Global 4，variable = [trackingcode] ，v1，v2]}，{scopeDef = https：//www.delta.com/,cope = Homepage 2，variable = [v4，v5，v6，v7]}，
]

执行代码后，我得到以下日志：

After I execute the code I get the following log:

第一个对象

{name=Global 4, rules=[{name=Global 4 OP SDR Sync, tags=[{variables=[
{}, 
{matchType=Regex, variable=trackingcode, value=.*}, 
{matchType=Regex, variable=v1, value=.*}, 
{matchType=Regex, variable=v2, value=.*}], condition=false, tagId=1.0}, {condition=false, tagId=1.0}], ruleSetId=3.0}], id=3.0}

第二个对象

name=Homepage 2, rules=[{name=Homepage 2 OP SDR Sync, tags=[{variables=[
{}, 
{matchType=Regex, variable=v4, value=https://www.delta.com/}, 
{matchType=Regex, variable=v5, value=https://www.delta.com/}, 
{matchType=Regex, variable=v6, value=https://www.delta.com/}, 
{matchType=Regex, variable=v7, value=https://www.delta.com/}], condition=false, tagId=1.0}, {condition=false, tagId=1.0}], ruleSetId=3.0}], id=3.0}

请注意，两个对象都包含一个空元素...为什么要添加该元素，如何摆脱它??

Note that both objects contain an empty element...why is that element added and how can I get rid of it??

推荐答案

你在这里定义了这个空对象：

You defined that empty object here:

"variables":[
              {
              }
            ],
