JavaScript拆分函数- Parentheses和Comma后的拆分

Question

我有一个ID列表，我试图使用JavaScript split()函数将其分开。每个ID的格式如下：

格式示例

(51.87,0.2125) // Lat and Long values with comma separation
(48.87,0.3130)

在JavaScript中，这些ID都存储在字符串中的值属性中。

示例：

(48.87,0.3130),(51.87,0.2125),(48.87,0.3130),(51.87,0.2125)

我的目标是在结束括号和逗号之后使用拆分函数。如何在考虑结束括号和逗号的情况下使用拆分函数？

目前，我有以下几点：

 var location_id = $(this).find("input").val().split(',');

期望输出

 ["(48.87,0.3130)","(51.87,0.2125)","(48.87,0.3130)","(51.87,0.2125)"]

Answer 1

您可以使用正则表达式/\(\d+\.\d+,\d+\.\d+\)/g

​

var str = '(48.87,0.3130),(51.87,0.2125),(48.87,0.3130),(51.87,0.2125)';
console.log(str.match(/\(\d+\.\d+,\d+\.\d+\)/g))

Answer 2

​

var data = "(48.87,0.3130),(51.87,0.2125),(48.87,0.3130),(51.87,0.2125)";

// Approach 1
var formattedData = data.split("),").map((el) => {
  return el.indexOf(")")==-1 ? el + ")": el;
});
console.log(formattedData);


// Approach 2 (replace , with | and then split using | )
formattedData2 = data.replace(/\),/g, ")|").split("|");
console.log(formattedData2);

Answer 3

见内嵌评论：

​

var s = "(48.87,0.3130),(51.87,0.2125),(48.87,0.3130),(51.87,0.2125)";
var location_id = s.split('),');

location_id.forEach(function(loc, i, ary) {
  // Put parens around the value with the left over parens removed
  ary[i] = "(" + loc.replace("(","").replace(")", "") + ")";
}); 
console.log(location_id);
