如何在javascript中解析多行/行数组

我想用多行和多行解析我的数组，我尝试使用 foreach 或 for 循环，但没有成功


var student = [

      {name:"alan",title:"al",platform:"test1",orderNumber:1 },

      {name:"frank",title:"fr", platform:"test2",orderNumber:1},

      {name:"bryan",title:"br", platform:"test3",orderNumber:1}

      ];


for (var i = 0; i < student.length; ++i) {

        window.alert(student[i]);

      }

它不起作用。我怎么能用循环解析这个数组并显示它？多谢

使用Object.entries()和forEach()迭代对象的属性。var student = [&nbsp; {name:"alan",title:"al",platform:"test1",orderNumber:1 },&nbsp; {name:"frank",title:"fr", platform:"test2",orderNumber:1},&nbsp; {name:"bryan",title:"br", platform:"test3",orderNumber:1}];student.forEach(item => {&nbsp; Object.entries(item).forEach(([key, value]) => {&nbsp; &nbsp; console.log(key + ": " + value);&nbsp; });});
