Error in function to return Querystring in Javascript

Question

When using this function by calling the filter parameter of an error, instead of returning the value of the Querystring parameter it returns a Function.

//Retorna os valores da querystring
function QueryString(pName)
{
    //Cria as variaveis
    var lQueryValue;
    var lQueryString = location.search.replace(/\x3F/, "").replace(/\x2B/g, " ").split("&");
    //Verifica se tem alguma query string
    if (lQueryString != "")
    {
        //Cria o array
        var lArray = [];
        //Roda em todos os caracteres da querystring
        for (var i = 0; i < lQueryString.length; i++)
        {
            //Quebra a query string
            lQueryValue = lQueryString[i].split("=");
            //Seta o valor do array
            lArray[lQueryValue[0]] = unescape(lQueryValue[1]);
        }
        //Armazena o retorno
        var lReturn = lArray[pName];
        //Retorna
        return lReturn;
    }
    return null
}

I found that this seems to be an array problem.

var lArray = [];
lArray['filter'];

Should return the Undefined value or the correct value, but returns the prototype string of the array filter function.

Does anyone have any tips on how to solve this problem ?

Friend what is happening is that in your array lArray you are added a key and then are trying to fetch it under another name. Change the following line:

lArray[lQueryValue[0]] = unescape(lQueryValue[1]);

For the following:

lArray[lQueryValue[0].substr(lQueryValue[0].indexOf('?') + 1)] = unescape(lQueryValue[1]);

I hope I helped friend
