Question

我有一个这样的数组：

 ["ID LONGITUDE LATITUDE", "0 77.139305 28.795975", "2 77.308929 28.486877", "4 73.820680 18.464110"]

我想这样做：

   var array= ["ID", "LONGITUDE", "LATITUDE", "0", "77.139305", "28.795975", "2", "77.308929", "28.486877", "4", "73.820680", "18.464110"]

怎么做？

Answer 1

如果你真的有一个数组，这里是如何简洁地做到这一点：

var rows = ["ID LONGITUDE LATITUDE", "0 77.139305 28.795975", "277.308929 28.486877", "4 73.820680 18.464110"];
[].concat.apply([], rows.map(function(row) { return row.split(' '); }))
// => ["ID", "LONGITUDE", "LATITUDE", "0", "77.139305", "28.795975", "277.308929", "28.486877", "4", "73.820680", "18.464110"]

Answer 2

请尝试以下代码：

var string_array =  ["ID LONGITUDE LATITUDE", "0 77.139305 28.795975", "2 77.308929 28.486877", "4 73.820680 18.464110"];

var new_string_array = [];

for(var strings in string_array) {
    var x = string_array[strings].split(" ");
    for(var sub_string in x) {
        new_string_array.push(x[sub_string]);
    }
}

alert(new_string_array);

Answer 3

可以使用reduce

完成

["ID LONGITUDE LATITUDE", "0 77.139305 28.795975", "2 77.308929 28.486877", "4 73.820680 18.464110"].reduce(function(arr, item) {

  item.split(' ').forEach(function(item) {
    arr.push(item)
  });

  return arr;
}, [])
