从Javascript | jQuery和Symfony2项目中的URL获得价值

Question

I need to get some parameters from URL using Javascript/jQuery and I found this nice function:

function getURLParameter(sParam) {
    var sPageURL = window.location.search.substring(1),
        sURLVariables = sPageURL.split('&');

    for (var i = 0; i < sURLVariables.length; i++) {
        var sParameterName = sURLVariables[i].split('=');
        if (sParameterName[0] == sParam) {
            return sParameterName[1];
        }
    }
};

So I started to use in my code but I'm having some issues since the parameter I'm looking for comes undefined . First, this is a Symfony2 project so Profiler gives me this information:

Request Attributes

Key                             Value
_route_params                   [registro => 1, solicitud => 58]
...
registro                        1
solicitud                       58

What I need from here is registro and solicitud . So what I did at Javascript side was this:

console.log(getURLParameter('registro')); // gets undefined

But surprise I get undefined and I think the cause is that registro is not present at URL which is http://project.dev/app_dev.php/proceso/1/58/modificar but it's present in the REQUEST. How I can get the registro and solicitud values from whithin Javascript? I need to send those parameters to a Ajax call, any advice?

Answer 1

Try using this function:

function getParameters(){
    var url = window.location.href; //get the current url
    var urlSegment = url.substr(url.indexOf('proceso/')); //copy the last part
    var params = urlSegment.split('/'); //get an array
    return {registro: params[1], solicitud: params[2]}; //return an object with registro and solicitud
}

Then you can call the function and use the values:

var params = getParameters();
console.log(params.registro);
console.log(params.solicitud);
