javascriptで多次元配列を表示しようとしています。誰かが私のコードについて助けてくれますか? ありがとう。

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.

    }

}

私の配列

配列はphpから作成され、json_encodeを使用してJSに解析します。

コードは正常に動作します。配列が無効である必要があります。

これを試して

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;
}

これは私にとってはうまく機能array = [[1,2],[3,4]];し、テスト配列 output: として使用されます1234。またはを行うと何が得られますdocument.write(JSON.parse(array));かconsole.log(array);？

私は通常、配列に for each を使用しますが、js では次のように実行できます

var array = [];
array[0] = ['foo', 'bar'];
array[1] = ['baz'];
for (i in array){
    for (j in array[i]){
       document.write(array[i][j])      //this won't.
    }
}

誰かがこれは安全ではないと言いましたが、それでも機能します :D
