Question

我有一个ID列表，我试图使用JavaScript split（）函数分开。每个ID都具有以下格式：

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都存储在字符串的value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后使用split函数。如何使用分割函数考虑右括号和逗号？

目前，我有这个：

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

所需输出

 ["(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

见内联评论：

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);

Answer 4

我能想到的最简单方法是将其拆分为,(，然后将其映射为删除所有(和)，因为第一个和最后一个条目将不一致，然后添加(和)重新开始：

＆＃13;

const str = '(48.87,0.3130),(51.87,0.2125),(48.87,0.3130),(51.87,0.2125)';

const result = str.split(',(')
    .map(x => '(' + x.replace('(','').replace(')','') + ')');

console.log(result);
