如何在字符串中添加12？

Question

嗨,我有一个包含URL的字符串,如下所示

http://www.myurl.com/abc/asdd/asd/rwewe/saaa/all-makes?expanded=no&s=true&searchLimit=12&searchOffset=24

我将URL存储在js字符串中,如下所示

var backToSearch = $(location).attr('href');
//typeof(backToSearch); 

我想在searchOffset中添加12,然后将其设置为cookie myCookie.

$.cookie('myCookie', backToSearch , {  path: '/' });

当添加12时,它就像

http://www.myurl.com/abc/asdd/asd/rwewe/saaa/all-makes?expanded=no&s=true&searchLimit=12&searchOffset=36

如何在字符串中添加12？

怎么样;

url = url.replace(/searchOffset=(\d+)/, function(a, b) {
    return "searchOffset=" + (parseInt(b, 10) + 12);
})
