我正在尝试在 javascript 中显示一个多维数组。有人能帮我解决一下我的代码吗？谢谢。
for (var i=0;i<array.length;i++){
for (var a=0;a<array[i].length;a++){
//document.write(array[0][0]) //this will have output
document.write(array[i][a]) //this won't.
}
}

我的数组
该数组由 php 创建，然后使用 json_encode 解析为 JS。

代码运行正常，你的数组一定无效。

这对我来说很有效，使用
array = [[1,2],[3,4]];
作为测试数组，输出：
1234
。当您执行
document.write(JSON.parse(array));
或
console.log(array);
时会得到什么？

尝试一下
function writeMultiArrayToConsole(arr)
{
var console = document.getElementById('mydiv');
var msg = '';
for(var i=0;i<arr.length;i++)
{
for(var j=0;j<arr[0].length;j++)
msg += arr[i][j];
msg += '<br />';
}
console.innerHTML = msg;
}
