Question

我的JavaScript数组存在问题。我想在每个数组元素后面有一个空格。这些元素以lat，long形式排列在倒置逗号中。数据以这种格式提供：

[23.4343,77.432342]，[24.4343,78.432342]，[22.4343,67.432342]等

此格式所需的数据：

['23.4343,77.432342'，'24 .4343,78.432342'，'22 .4343,67.432342'，'25 .4343,68.432342'，'33 .4343,79.499342']

Answer 1

var input = [ [1, 2], [2, 3], [3, 4] ];

var output = input.reduce(function(arr, val) {
  arr.push(val[0]); // For strings use `String(val[0])`
  arr.push(val[1]); // For strings use `String(val[1])`
  return arr;
}, []);

console.log(output); // [1, 2, 2, 3, 3, 4]

Answer 2

假设[23.4343, 77.432342], [24.4343, 78.432342], [22.4343, 67.432342]为array of arrays

var myarray=[[23.4343, 77.432342], [24.4343, 78.432342], [22.4343, 67.432342]];
var finalarray=[];
for(i=0;i<myarray.length;++i){
    var string='';
    for(j=0;j<myarray[i].length;++j){
        string+=myarray[i][j]+',';    
    }
    debugger
    string = '\''+string.substring(0, string.length-1)+'\'';

    finalarray.push(string);
}
alert(finalarray);

如何在每个元素之前自定义带有空格的javascript数组？
