Symfony2：如何在另一个js中包含一个js文件？

I am using intl-tel-input plugin in a Symfony project. We currently combine Assets in order to load all js script files into one.

However the intl-tel-input plugin requires utils.js in order to enable formatting/validation etc. and it needs to be included inside the script, like this:

utilsScript: "/Resources/js/vendors/utils.js"

However if I use that I get a 404 error (file utils.js not found).

How can I load that file on the script?

This is my complete script:

$(".js-phone").intlTelInput({
    autoFormat: false,
    autoHideDialCode: false,
    autoPlaceholder: true,
    defaultCountry: "auto",
    geoIpLookup: function(callback) {
      $.get('http://ipinfo.io', function() {}, "jsonp").always(function(resp) {
        var countryCode = (resp && resp.country) ? resp.country : "";
        callback(countryCode);
      });2
    },
    nationalMode: false,
    utilsScript: "{{ include('/Resources/js/vendors/utils.js') }}" // utils.js enables formatting/validation etc. 
});

According to documentation you provided utilsScript requires path to js file. You can't just use /Resources/js/vendors/utils.js since Resources is not a public directory.

Twig's include is meant to INCLUDE file contents, so what you need to use is asset function:

$(".js-phone").intlTelInput({
    (..)
    utilsScript: "{{ asset('bundles/yourbundle/js/vendors/utils.js') }}" 
});
