Question

好的，所以我有两种方法来执行div刷新

$( #player ).load( /videos/index );

在我的rails应用程序中。一个是通过链接

<a href="#" id="nextb" onclick="$( #player ).load( /videos/index ).unbind();">next</a>

other is through shortcut of that button. And they work fine, until i discovered, that if I refresh player twice in a row through the link, and then through the shortcut, it loads div twicely. If i refresh through the link three times in a row, than through the shortcut, than it s loading div three times. And so on.. So, i ve started to trying configure binds (as I assumed, that was the reason), but there were mo result. Here is my messed up in binds shortcut part of application.js

 $(document).ready(function(){;
$(document).bind( keydown ,  space , function() {
    $( #player ).unbind( load );    
    $( #player ).load( /videos/index );
    $(document).unbind();
    }); 
 });

我试图通过快捷方式点击链接，但结果相同，所以我认为问题出在加载中。任何建议都会有所帮助。

避免双重刷新的最佳方法是使用状态标志，指示是否可以再次加载或是否正在加载：

$(document).ready(function() {
    var loading = false;
    function reloadDiv() {
        if(!loading) {
            loading = true;
            $( #player ).load( /videos/index , null, function() { loading = false; });
        }
    }  
    $( #nextb ).click(reloadDiv);
    $(document).bind( keydown ,  space , reloadDiv);
});

祝你好运
