Question

我想将数据发送到我的Django视图，同时重定向页面。所以，我认为ajax不在窗口。我不确定如何通过Jquery做到这一点。

Answer 1

你不需要jQuery。 Create a form that performs a POST to the appropriate URL并提交。

Answer 2

这是我通过POST将数据发送到Django服务器的代码。我访问了Ignacio建议的网站，并添加了csrf，因此它可以与典型的Django视图一起使用。

    // get cookie using jQuery
    function getCookie(name) {
        var cookieValue = null;
        if (document.cookie && document.cookie != '') {
            var cookies = document.cookie.split(';');
            for (var i = 0; i < cookies.length; i++) {
                var cookie = jQuery.trim(cookies[i]);
                // Does this cookie string begin with the name we want?
                if (cookie.substring(0, name.length + 1) == (name + '=')) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                    break;
                }
            }
        }
        return cookieValue;
    }


    function post_to_url(path, params, method) {
        method = method || "post"; // Set method to post by default if not specified.

        // The rest of this code assumes you are not using a library.
        // It can be made less wordy if you use one.
        var form = document.createElement("form");
        form.setAttribute("method", method);
        form.setAttribute("action", path);

        for(var key in params) {
            if(params.hasOwnProperty(key)) {
                var hiddenField = document.createElement("input");
                hiddenField.setAttribute("type", "hidden");
                hiddenField.setAttribute("name", key);
                hiddenField.setAttribute("value", params[key]);

                form.appendChild(hiddenField);
             }
        }

        csrfField = document.createElement("input");
        var csrftoken = getCookie('csrftoken')
        console.log("token" + csrftoken)
        csrfField.setAttribute("type", "hidden");
        csrfField.setAttribute("name", "csrfmiddlewaretoken");
        csrfField.setAttribute("value", csrftoken)
        form.appendChild(csrfField)

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