Javascript Grails中的HTML5

我试图在grails应用程序中使用HTML5 SSE。下面是正在运行的示例代码：

def push(){
    println "Inside action..."
    response.setContentType("text/event-stream");
    response.setCharacterEncoding("UTF-8");
    render("data: ${System.currentTimeMillis()}");
}

客户端代码：

<script type="text/javascript">
    if(typeof(EventSource) !== "undefined") {
        var source = new EventSource("push");
        source.onmessage = function(event) {
            console.debug("event triggered...");
            document.getElementById("result").innerHTML += event.data + "<br>";
        };
        source.onerror = function(event) {
            console.log(event.message);
        }
    } else {
        document.getElementById("result").innerHTML = "Sorry, your browser does not support server-sent events...";
    }
</script>

但是不起作用

请建议。

好吧，我解决了。我用过：

    PrintWriter writer = response.getWriter();

    writer.write("data:"+System.currentTimeMillis()+"\n\n")

它成功了。

Hello Vivek，您是如何在控制器/操作完成后刷新数据并避免连接关闭的？

    PrintWriter writer = response.getWriter();

    writer.write("data:"+System.currentTimeMillis()+"\n\n")
