JavaScript: Extract one element out of an array that is created after php json encode

var Array = [["1","123","3","3","3","20"],["2","253","2","2","2","15"],["3","222","4","4","4","15"],["4","353","5","5","5","15"]];
alert(Array[0][0]);

这将仅打印 [.请建议如何在数组中循环打印单个元素。或者只是第一个数组元素的单个元素。

试试这个

$Array = [["1","123","3","3","3","20"],["2","253","2","2","2","15"],    ["3","222","4","4","4","15"],["4","353","5","5","5","15"]];
foreach($arrays as $array){
   foreach($array as $val){
     echo $val.'<br>';
   }

}

在 Javascript 中

var Arrays = [["1","123","3","3","3","20"],["2","253","2","2","2","15"],["3","222","4","4","4","15"],["4","353","5","5","5","15"]];
 var val='';
 var i=0;var j=0; 
 for(i=0;i<Arrays.length;i++){
  var temp=Arrays[i];
      for(j=0 ;j<temp.length;j++){
             alert(Arrays[i][j]);
      }
 }
