第一種種拼接json的key會(huì)過(guò)濾雙引號(hào)

    var arr = "sequence" + ":" + "[";
    let arrEnd = "]";
    for(let i=0;i<[1,2,3].length;i++){
      arr += "{" +"sequence" + ":" + [1,2,3][i] + "," + "process" + "[" + [[1,2,3],[2,4],[5,4]][i]+"]"+"}"+",";
    }
    let arrs = '{' + arr.substring(0,arr.length-1)+arrEnd + '}';
    console.log(arrs);//{sequence:[{sequence:1,process[1,2,3]},{sequence:2,process[2,4]},{sequence:3,process[5,4]}]}
    

第二種拼接數(shù)組[1,2,3]會(huì)被當(dāng)字符串處理

    var arr = "sequence" + ":" + "[";
    let arrEnd = "]";
    for(let i=0;i<[1,2,3].length;i++){
      arr += "{ \"sequence\": [1,2,3][i], \"process\": [[[1,2,3],[2,4],[5,4]][i]]}"+",";
    }
    let arrs = JSON.stringify('{' + arr.substring(0,arr.length-1)+arrEnd + '}');
    console.log(JSON.parse(arrs)); /*{sequence:[{ "sequence": [1,2,3][i], "process": [[[1,2,3],[2,4],[5,4]][i]]},{ "sequence": [1,2,3][i], "process": [[[1,2,3],[2,4],[5,4]][i]]},{ "sequence": [1,2,3][i], "process": [[[1,2,3],[2,4],[5,4]][i]]}]}*/

求一種拼接完能和json格式一樣的方法,然后要能取的到值
