Question

我的JSON数据在

之下

{
"response_code": 200,
"train": [
    "19005 (SAURASHTRA MAIL)",
    "19066 (BGKT BDTS EXP)"
],
"total": 2 }

其他格式低于相同数据

{
"response_code": 200,
"train": [
    "(SAURASHTRA MAIL) (19005)",
    "(BGKT BDTS EXP) (19066)"
],
"total": 2  }

从以上两种格式我想分开 19005 ＆amp;两个值 SAURASHTRA MAIL 和弹出警报消息。

如何拆分？请帮忙

Answer 1

您可以使用正则表达式并在级联中执行匹配。结果是一个包含整个结果和拆分值的数组。

var train = [
    "19005 (SAURASHTRA MAIL)",
    "19066 (BGKT BDTS EXP)",
    "(SAURASHTRA MAIL) (19005)",
    "(BGKT BDTS EXP) (19066)"
];

train.forEach(function (a) {
    var m = a.match(/\((.*)\) \((.*)\)/);
    if (m) {
        console.log('1number: ' + m[2]);
        console.log('1string: ' + m[1]);
        return;
    }
    m = a.match(/(.*) \((.*)\)/);
    if (m) {
        console.log('2number: ' + m[1]);
        console.log('2string: ' + m[2]);
    }
});

Answer 2

var str1 = "19005 (SAURASHTRA MAIL)";
var train_name1= str1.match(/\((.*?)\)/)[1];
var train_number1 = str1.match(/\d+/g);

var str2 = "(SAURASHTRA MAIL) (19005)";
var train_name2= str2.match(/\((.*?)\)/)[1];
var train_number2 = str2.match(/\d+/g);


alert("TRAIN NAME 1 : "+train_name2 +" AND TRAIN NUMBER : "+ train_number2 +", TRAIN NAME 2 : "+train_name2 +" AND TRAIN NUMBER : "+ train_number2);

我写了这个正则表达式，它似乎做了你想要的

\"\((.*)?\)\s*\((\d*)\)\"|\"(\d*)\s*\((.*)?\)\"/g

'/ g'是将正则表达式应用于所有行的修饰符

我想将JSON值拆分为两个值
