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 = [
{name:"alan",title:"al",platform:"test1",orderNumber:1 },
{name:"frank",title:"fr", platform:"test2",orderNumber:1},
{name:"bryan",title:"br", platform:"test3",orderNumber:1}
];
student.forEach(item => {
Object.entries(item).forEach(([key, value]) => {
console.log(key + ": " + value);
});
});
