                #### 1、問題描述 每次時間軸交互以后,都需要停掉之前的websocket連接以免展示的查詢數據又瞬間被推送回來的新數據更新掉,所以每次點擊時間查詢按鈕時都要調用ws.close()方法關閉websocket推送。然而,close方法并沒有生效 #### 2、問題原因 Websocket的close方法要先注冊,再使用才能生效 #### 3、解決方案 為創建的websocket對象注冊close方法,然后再調用,即可生效 ```javascript var ws = new WebSocket(url); ws.onopen = function() { ws.send(JSON.stringify(param)); } ws.onmessage = callback //注冊close事件,否則close方法不會生效 ws.onclose = function() {} ```
