javascript - 我的数组中元素的值始终未定义

Question

因此，在 Javascript 中，我创建了一个数组并推送了一些数据：

var arrayAddress = new Array();
arrayAddress.push(data1);
arrayAddress.push(data2);
//etc...

有了一个console.log(arrayAddress)，我有：

[]              
0   48.8557669      
1   2.3587343       
2   "Paris"     
3   "France"    
4   "75004"

如何检索此数组中的元素？如果我尝试arrayAddress[n]我有“ undefined”...

Answer 1

也许它可以帮助你

$(document).ready(function(){
var arrayAddress = new Array();
 var data1 = [ "one", "two", "three", "four", "five" ];
 var data2 = [ "six", "seven", "eight", "nine", "ten" ];
  arrayAddress.push(data1);
  arrayAddress.push(data2);
 for(i=0; i < arrayAddress.length; i++){
  var newarrobj = arrayAddress[i];
  //alert(arrayAddress[i]);
  for(j=0; j < newarrobj.length; j++){
   alert(newarrobj[j])
  }
}
});

试试这个arrayAddress.at(n)。希望它会有所帮助。
