Question

我想通过异步通信将表单数据发送到test.html。我在index.html中写道

<body>
　  <form method="post" action="">
    <select id="mainDD" data-placeholder="Choose" class="chzn-select" style="width:600px;">
    {% for i in json_data.items.values %}
            <option value="{{forloop.counter}}">{{ i }}</option>
    {% endfor %}
    </select>

    {% for key, values in preprocessed %}
    <select name="type" id=type{{forloop.counter}}>
    {% for counter, value in values %}
        <option value="{{forloop.counter}}">{{ value }}</option>
    {% endfor %}
    </select>
    {% endfor %}
    </form>

  <script type="text/javascript">

        $(document).ready(function () {
            $('#mainDD').on('change', function() {
              var thisType = "type" + $(this).val();
              for(i=1; i<6; i++) {
                  var thisId = "type" + i;
                  if(thisType !== thisId) {
                    $("#"+thisId).hide();
                  }
                  else {
                    $("#"+thisId).show();
                  }
              }

            }).trigger('change');

        });


  </script>

     <form id="postform" action="http://localhost:8000/app/test_view" method="POST">
      {% csrf_token %}
      <input type="submit" value="SEND">
     </form>
     <script type="text/javascript">
            $('[name=type]').change(function() {
            var array1 = [];
            var array2 =[];
                $('[name=main] option:selected').each(function() {
                array1 = $(this).text();
                console.log(array1);
            });

                $('[name=type] option:selected').each(function() {
                array2 = $(this).text();
                console.log(array2);
            });
        });
        $.ajax({
            url: 'test.html',
            dataType: 'html',
            timeout:3000,
            async: true,
            success: function(html) {
                $('.newsarea').html(html).fadeIn(5000);
            },
            error: function() {
                alert('Error');
            }
        });
     </script>
  </body>

我想发送选定的i＆amp;值的变量为test.html。现在，当我放置发送按钮时，test.html中没有显示任何内容。我写了像test.html一样的

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>RESULT</title>
</head>
<body>

<h2>TOPIC</h2>
<div class="newsarea">
</div>

</body>
</html>

我想展示精选的i＆amp;价值在这个地方的价值。我的代码出了什么问题？如何解决这个问题？

如果document来源于与原始document相同的来源，并且通过用户操作打开，则可以将参数作为查询字符串传递。

  document.querySelector("input[type=button]").onclick = e => {
    // pass key, value pairs to `test.html`
    const test = window.open(`test.html?${key}=${value}`, "_blank");
  }

在打开的window获取并解析location.search

  onload = () => {
    // do stuff with key, value pairs passed from `window.opener`
    console.log([...new URLSearchParams(location.search).entries()])
  }
