angular - 为什么 concat 在合并 2 个对象数组时会抛出错误

Question

嗨，我收到错误

concat is not a function

我正在尝试的是

    searchResults:any;   // inside class export
    results:any


 this.candidateSearch.postSearch(this.searchedInput,"candidateSearch").then((result)=>{

     this.results = result;

     console.log(this.results.details);       

    this.searchResults = this.searchResults.concat(this.results);   // throwing error      


          }, (err) => { 

        });

我的结果采用以下格式:

{
    "details": [{
        "company_name": "Cybrain Software Solutions",
        "skills": "php,laravel",
        "package": "15 lakh",
        "location": "Bengaluru",
        "industry": "Software",
        "job_type": "permanent"
    }, {
        "company_name": "Floret Media Pvt Ltd",
        "skills": "php",
        "package": "10 lakh",
        "location": "Bengaluru",
        "industry": "software",
        "job_type": "per"
    }]
}

我的问题:我想合并之前的结果

编辑:我希望 searchResults 数组在连接后采用以下格式 {"details":[{},{},{}]}

Answer 1

您需要初始化数组

searchResults:any = [];
