通过带有参数的javascript调用django url

Question

This is my javascript function where I pass parameters, using alert I checked that function is getting the parameters I want but I am unable to pass them in django url other wise giving a string the url works but not with parameters.

      function myFunction(a) {
      var v = a.value;
      alert(v);
      location.href="{% url 'new_event' v %}"; //does not works
      location.href="{% url 'new_event' 'string' %}"; //works
      }

I have checked the value getting is string the way I want but how to pass it?

Answer 1

kindly try this:

    function myFunction(a) {
        var v = a.value;
        alert(v);
        location.href="{% url 'new_event' v %}"; // this will not work because your django **url** filter is pre-processed on your server while your javascript variable is processed on **client**
        // if you want your variable v to be dynamic, you need to include it in your django's view **context**
        location.href="{% url 'new_event' 'string' %}"; //works
    }

    // include in your views.py
    context['v'] = 'some-string'

    // template.html
    <script>
        function myFunction(a) {
            var v = '{{ v }}'; // javascript variable v
            alert(v);
            location.href="{% url 'new_event' v %}"; // django context variable v
        }
    </script>

使用确切的网址，即new / value1 / value2 /

Answer 3

Use

location.href = "/" + v

where v is your id or slug
