URL parameters on javascript

Question

I´m making a call using javascript and I would like to send an array:

var selected = [];
selected=getAllEnginesIdsSelected();
    console.log("selected: "+selected);
    $.getJSON('/call/' + selected,
            function(myList) {

The funcion that I use in Javascript to retrieve array is:

function getAllEnginesIdsSelected() {

        var selected = [];

        $("input:checkbox[id^='engine_']:checked").each(function(){
            var ele=$(this)[0].id;
            selected.push(ele);
        });

        return selected;

    }

Console.log retrieves selected: 2,5

In MVC Controller I have

@RequestMapping(method = RequestMethod.GET, value = "/call/{selected}")
public List<List<myList>> myCall(@RequestParam(value="selected[]") String[] selected){

I gives an error. I don´t want to use AJAX. This is posible to send?

Unless I'm missing something, getAllEnginesIdsSelected() is always going to return an empty array. — David W

Btw you can totally drop this: selected = []; in the first code snippet. You can directly assign the method to the variable. — Tom

You can't use getJSON to send data. You'd be better off using $.post(). — Tom

selected is an array, which you are joining to a string in the URL. Try something like $.getJSON('/call/?selected=[' + selected.join(',')]
