{% url org_select_book_list %}
在我使用该功能进入新页面之前reload_books
,我需要发布一些值,并且需要将数据存储在{% url org_store_select_book_list %}
.
但我无法接收数据。
但是当我评论时reload_books();
,我可以收到它。为什么?
在这里我添加视图,我不知道它是否可以工作。注意:这HttpResponse
仅用于测试目的。
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;
