如何在我的数组中使用 javascript 中的 foreach？

Question

<p id="demo"></p>

<script>

var myObj, i, x = "";

myObj = {

      "__type": "DocumentLibraryHelps.Methods.Instruction",

      "name": "IT-DSM-WI-003-RU_Управление BI Cloud_Ред.03.pdf",

      "url": "https://cloud.bi-group.org/instr/BI Cloud/IT-DSM-WI-003-RU_Управление BI Cloud_Ред.03.pdf?web=1",

      "type": "Microsoft.SharePoint.SPFile",

      "category": "Cloud",

      "section": "Cloud"

    },

    {

      "__type": "DocumentLibraryHelps.Methods.Instruction",

      "name": "IT-DSM-WI-002-RU_Разграничение прав доступа к BI Cloud_Ред.02.pdf",

      "url": "https://cloud.bi-group.org/instr/BI Cloud/IT-DSM-WI-002-RU_Разграничение прав доступа к BI Cloud_Ред.02.pdf?web=1",

      "type": "Microsoft.SharePoint.SPFile",

      "category": "Cloud",

      "section": "Cloud"

    },

    {

      "__type": "DocumentLibraryHelps.Methods.Instruction",

      "name": "Инструкция_Галерея.docx",

      "url": "https://cloud.bi-group.org/instr/Life/Инструкция_Галерея.docx?web=1",

      "type": "Microsoft.SharePoint.SPFile",

      "category": "ERP: Первые шаги",

      "section": "1C: ERP"

    };

for (i = 0; i < myObj.cars.length; i++) {

  x += myObj.name[i]  +=  myObj.url[i]  += myObj.type[i] + "<br>";

}

document.getElementById("demo").innerHTML = x;

</script>

我通过使用 get 方法拥有该数组，我需要按类型在不同类别中按“for”编写？如何使用功能正确？我的错误在哪里？

你的对象无效，这在你的第一个括号之后结束，当你改变它时，它应该循环for(let obj in myObj){}并让你的 vals 更像 myObj[obj].type
