javascript - 尝试将字符串数据转换为数值数据，将数据放入数组数组(Json)中

Question

我有这个:

    (65.94647177615738, 87.890625)(47.040182144806664, 90)(45.089035564831036, 122.34375)

我试图让输出看起来像这样:

   "coords": [[65.94647177615738, 87.890625],[47.040182144806664, 90],[45.089035564831036, 122.34375]]

有什么想法吗？

第一个结果以字符串形式返回给我，因此当我尝试将第一个对象分配给数组时，控制台会向我显示以下内容:

  array is:  "(65.94647177615738, 87.890625)(47.040182144806664, 90)(45.089035564831036, 122.34375)"

Answer 1

var str = "(65.94647177615738, 87.890625)(47.040182144806664, 90)(45.089035564831036, 122.34375)";
str = str.slice(1,-1); // remove outermost parentheses
var arrCoord = str.split(')(');  
for (var i=0; i<arrCoord.length; i++) {
    var tarr = arrCoord[i].split(", ");
    for (var j=0; j<tarr.length; j++) {
        tarr[j] = parseFloat(tarr[j]);
    }
    arrCoord[i] = tarr;
}
// arrCoord is now populated with arrays of numbers
