原型 Ajax 更新不起作用
我正在使用 Prototype，同时使用 pylons 框架并尝试进行 Ajax 调用。
我的 html 如下所示：
<form method="POST" action = "javascript:void(0)" onsubmit = "new Ajax.Updater('graph','/saffron_main/click_out_display'); ">
<label for="tids">Select Relevant Tids</label>
<select id="tids" multiple="multiple" name="tids" title="Tids">
<option>1</option>
<option>2</option>
</select>
<p><input class = "button" type="submit" name="submit" value="submit" /></p>
</form>
<div id = "graph">
</div>
我可以看到我的控制器被调用，并向 /saffron_main/click_out_display 发出了 http 请求。一切看起来都工作正常。唯一的问题是 div 永远不会被填充。我正在拔出我的头发试图弄清楚这个问题，任何帮助将不胜感激！谢谢！
I am working with Prototype while using the pylons framework and trying to make an Ajax call.
Here is what my html looks like:
<form method="POST" action = "javascript:void(0)" onsubmit = "new Ajax.Updater('graph','/saffron_main/click_out_display'); ">
<label for="tids">Select Relevant Tids</label>
<select id="tids" multiple="multiple" name="tids" title="Tids">
<option>1</option>
<option>2</option>
</select>
<p><input class = "button" type="submit" name="submit" value="submit" /></p>
</form>
<div id = "graph">
</div>
I can see that the my controller gets called and a http request gets made to /saffron_main/click_out_display. Everything looks like it is working properly. The only problem is the div never gets populated. I am pulling out my hair trying to figure this one out and any helps would be greatly appreciated! Thanks!

如果在实例化
Ajax.Updater后将return false;放入 onsubmit 中，会发生什么情况？为什么-
目前默认情况下会返回 true，并且页面可能会被回发，而不是通过 Ajax
What happens if you put a
return false;inside the onsubmit after you instantiate anAjax.Updater?Why -
It currently would be returning true by default and the page may be getting posted back, not via Ajax
