我有这个:

<>之前(65.94647177615738, 87.890625)(47.040182144806664, 90)(45.089035564831036, 122.34375)之前

我试图让输出看起来像这样:

<>之前"cods":[[65.94647177615738,87.890625]，[47.040182144806664,90]，[45.089035564831036,122.34375]]之前

任何想法?

第一个结果作为字符串返回给我，所以当我尝试将第一个对象分配给数组时，控制台显示给我:

<>之前数组是:"(65.94647177615738,87.890625)(47.040182144806664,90)(45.089035564831036,122.34375)" 
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

决定玩代码高尔夫。假设:

var sample = '(65.94647177615738, 87.890625)(47.040182144806664, 90)(45.089035564831036, 122.34375)';

: 

var coords = sample
    .split(/'(([^)]+)')/)
    .filter(function(v){return v!=""})
    .map(function(v){return v.split(/[^0-9'.]+/)})
