javascript - window.location.href の場合、JavaScript から投稿値を取得できません

Question

{% url org_select_book_list %}関数 を使用して新しいページに移動する前にreload_books、いくつかの値を投稿する必要があり、データを に保存する必要があります{% url org_store_select_book_list %}。

しかし、データを受信できません。

でも にコメントするreload_books();と、受け取ることができます。なんで？

ここでビューを追加しますが、それが機能するかどうかはわかりません。注: はHttpResponseテスト目的のためだけのものです。

function reload_books() {  
        var new_url = '{% url org_select_book_list %}?type=' + type  
                + '&order_by=' + order_by + '&page=' + page  
                + '&per_page=' + per_page + '&q=' + q;  
        for (var i = 0; i < search_param_stack.length; i ++) {  
            new_url += '&' + search_param_stack[i] + '=' + eval(search_param_stack[i]);  
        }  

        window.location.href = new_url;
    }


function change_page(new_page) {
        if (new_page < 1) {
          strong textpage = 1;
        } else if (new_page > {{ book_list.paginator.num_pages }}) {
            page = {{ book_list.paginator.num_pages }};
        } else {
            page = new_page;
        }

        form.appendChild(page_from);

        var bookId = document.getElementsByClassName("batch_cb");
        var page_length = {{ book_list.end_index }} - {{ book_list.start_index }};

            }
            form.appendChild(YAhiddenField);
        }

        document.body.appendChild(form);
        form.submit();
        document.body.removeChild(form);

        reload_books();
