How do I make this array of params in a parent param in jQuery?

This is my call as it is :

$(this.form).attr("action",$(this.form).attr("action") + '?' + $("#sortable").sortable('serialize') + "&foo[]=bar");

Which creates this :

importance[]=1&importance[]=2&importance[]=3

My problem is is that I want these params to be apart of card_开发者_StackOverflow中文版signup

So that in card_signup, I would have importance[1, 2, 3]

How can I alter my original call so that the importance params will appear within the card_signup param?

You'll need to parse the serialized return to do that.

You could also modify this code to save having to read the attribute twice in your code.

 $(this.form).attr("action", function(index, action) {
    var values = [],
        getKey;

    $("#sortable").sortable('serialize').replace(/(\w+?)\[]=(\d+?)/g, function(all, key, number) {
        values.push(number);
        getKey = key;
    });

    var cardSignupGetParams = 'card_signup=' + getKey + '[' + values.join(', ') + ']';
    return action + '?' + cardSignupGetParams + "&foo[]=bar";
});
