Question

我在index.html中使用提示请求用户名。我的代码如下所示：

<script>
      // YOU DO NOT NEED TO EDIT THIS CODE
      if (!/(&|\?)username=/.test(window.location.search)) {
        var newSearch = window.location.search;
        if (newSearch !== '' & newSearch !== '?') {
          newSearch += '&';
        }
        var username = prompt('What is your name?') || 'anonymous';
        console.log("From Index.html:" , username);
        newSearch += 'username=' + (username);
        window.location.search = newSearch;
      }
    </script>

我需要在app.js中访问此用户名。我正在向需要用户名作为属性的服务器发送POST请求。例如：

      //POST the message to the server
  handleSubmit: function() {
    var query = window.location.search;
    var username = query.slice(10, query.length);
    var room = $('#roomSelect').find(':selected').text();
    var msg = {
      username: username,
      text: $('#message').val(),
      roomname: room
    };
    app.send(msg);
    console.log(msg);
    app.renderMessage(msg);
  }

基本上，我想在index.html中提示用户输入用户名，但如何从app.js访问此变量？我会以某种方式将其发回给该文件吗？

您可以尝试将其存储在会话变量中，然后从任何地方访问它
