正则表达式，用于从URL提取客户/订单号

Question

I am hoping a regex guru can help to solve my issue,

I want to search the following URL's to extract certain pieces of data:

• /#!/customers/2848060/orders/9234573/history

  1. I want one regex function to extract the number following 'customers' string (2848060) .

  2. I want another regex to extract the number following the word 'orders' (9234573) .

Any help would be massively appreciated.

Answer 1

I want one regex function to extract the number following 'customers' string (2848060).

/(?<=customers\/)(.*)(?=\/orders)/g

I want another regex to extract the number following the word 'orders' (9234573).

/(?<=orders\/)(.*)(?=\/history)/g

Following is snippet for test

 var str = '/#!/customers/2848060/orders/9234573/history' var customer = str.match(/(?<=customers\\/)(.*)(?=\\/orders)/g)[0] var order = str.match(/(?<=orders\\/)(.*)(?=\\/history)/g)[0] console.log(customer); console.log(order); 

Alternative Solution

I want one regex function to extract the number following 'customers' string (2848060).

/customers\/(.*)\/orders/

I want another regex to extract the number following the word 'orders' (9234573).

/orders\/(.*)\/history/

Following is snippet for test

 var str = '/#!/customers/2848060/orders/9234573/history' var customer = str.match(/customers\\/(.*)\\/orders/)[1] var order = str.match(/orders\\/(.*)\\/history/)[1] console.log(customer); console.log(order); 

Answer 2

I want one regex function to extract the number following 'customers' string (2848060)

Use capturing groups

For customer /customers\\/(\\d+)/

var matches = "/#!/customers/2848060/orders/9234573/history".match( /customers\/(\d+)/ );
if (matches)
{
   console.log( "customers " + matches[1] );
}

I want another regex to extract the number following the word 'orders' (9234573).

Similarly for orders /orders\\/(\\d+)/

Also, you may not need regex if you URL pattern is likely to be the same

var items = str.split( "/" );
var customers = items[4];
var orders = items[6];

Answer 3

var r = /\d+/g;
var s = "/#!/customers/2848060/orders/9234573/history";
var m;
while ((m = r.exec(s)) != null) {
  alert(m[0]);
}
