How to create dynamic regex in javascript

Question

I want to use $htppBackend to mock some service. My problem is some of service url have parameter, ex: http://domain/service1?param1=a&param2=b

I need an regex which can reconize http://domain/service1<whatever> is correct for http://domain/service1?param1=a&param2=b. One thing, the first part http://domain/service1 is not a constant, it can be http://domain/service2/sth/anything.

Please help. Thanks.

Edit:

I put my code here to make it easy to understand.

I have 4 api urls:

angular
    .module('moduleName')
    .constant('getApi', {
        attrList: 'http://domain/setup/attrList',
        eventList: 'http://domain/setup/eventList',
        vcList: 'http://domain/api/list1',
        getRaDetails: 'http://domain/abc/getDetails?raId={0}&bookId={1}'
    });

With attrList, eventList and vcList, they are ok with $httpBackend.whenGET(getApi.attrList).respond(responseObject); $httpBackend.whenGET(getApi.eventList).respond(responseObject); $httpBackend.whenGET(getApi.vcList).respond(responseObject);.

But the last one getRaDetails, it doesn't work with $httpBackend.whenGET(getApi.getRaDetails).respond(responseObject); because raId and bookId have different value each times.

Now I need a regex to make this rule - $httpBackend.whenGET(getApi.getRaDetails).respond(responseObject); works with all raId and bookId value.

Hope it can explain my question more clearly. Thanks

Answer 1

This's my working code:

_(getApis).each(function (api) {
                var val = api.value.split('?')[0].replace(/\//g, '\\/'),
                    reg = new RegExp(val);

                $httpBackend.whenGET(reg).respond(dummy[api.key]);
            });

Thanks all.
