Ext做的简单登录界面（验证码刷新）
初学Ext，刚刚用Ext做了个登录界面，其中的验证码刷新出现了问题，试了好久都没好使，后来想起来再jQuery里的ajax方法是异步的,如果每次请求的URL不变的话，就会由缓存来处理请求，所以需要一个时间戳，保证每次请求的URL不同，在这里加了一下时间戳就可以了，我想这里的原理也应该和jQuery的那个是一样的，贴个代码吧</p> </p><div class="aged2"><script type="text/javascript">a("article_content_down");</script></div> </div> <div id="pagebox" > <a href="/jiaocheng/webqd/" target="_blank">查看更多</a> <A href="/jiaocheng/20130804/1354055.html" title="jquery怎么判断显示隐藏汇总">下一篇</A></div> <div id="MainLeftll"> <div id="MainLeftllToolbar">本文网址：<a href="https://www.reader8.com/jiaocheng/20121009/1354060.html">https://www.reader8.com/jiaocheng/20121009/1354060.html</a></div> <div class="related"><span class="relatedIco1">读书人精选</span> <ul class="relatedList"> </ul> </div> <div class="aged3"><script type="text/javascript">a("article_content_down2");</script></div> <div class="aged3a"><script type="text/javascript">a("article_content_down3");</script></div> </div> </div> <!-- 文章正文左边结束 --> <!-- 文章正文右边开始 --> <div class="leftbox_r"> <div class="aged4"><script type="text/javascript">a("article_right_up");</script></div> <div class="Rtitle"> <span class="Rtitle_text">热点排行</span></div> <div class="RContl"> <ul> <li><a href="/jiaocheng/20140117/1301491.html" target="_blank">jquery的after与insertAfter的差异</a></li> <li><a href="/jiaocheng/20121007/1266280.html" target="_blank">牛角尖啊牛角尖</a></li> <li><a href="/jiaocheng/20131226/1352920.html" target="_blank">weblogic 认证回绝 Authentication for </a></li> <li><a href="/jiaocheng/20120828/1264084.html" target="_blank">菜鸟阅读Servlet源码值得注意的地方</a></li> <li><a href="/jiaocheng/20120907/1267538.html" target="_blank">[转]Remote Debugging with Eclipse + W</a></li> <li><a href="/jiaocheng/20131015/1300997.html" target="_blank">（四）事件处理——（6）给.ready()回调</a></li> <li><a href="/jiaocheng/20131016/1342193.html" target="_blank">（四）事件处理——（8）一个简单的风格</a></li> <li><a href="/jiaocheng/20121118/1270056.html" target="_blank">元素正中的几种方法</a></li> <li><a href="/jiaocheng/20121101/1270755.html" target="_blank">判断iframe是不是加载完毕的方法（兼容i</a></li> <li><a href="/jiaocheng/20130314/1270976.html" target="_blank">velocity获取session值并判断是不是成</a></li> </ul> </div> <div class="aged7"><script type="text/javascript">a("article_right_up2");</script></div> <!-- 文章正文右边结束 --> </div> <!--主体结束--> <script type="text/javascript">a("article_down_up");</script> <script type="text/javascript">a("foot");</script> <script type="text/javascript">a("article_down_up2");</script> <!--主体结束--> <div style="display:none"> <!--百度统计代码--> <script> var _hmt = _hmt || []; (function() { var hm = document.createElement("script"); hm.src = "https://hm.baidu.com/hm.js?d6151f323a57d16696165e47eee86d53"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(hm, s); })(); </script> </div> <script type="text/javascript">a("allbt");</script> </body> </html>
