Coolite Cool Study 2 同时更新多个Tab

 更新时间:2009年05月17日 09:40:09   作者:   我要评论
前段时间有一个需求是这样子的——录入一个查询条件, 出来的查询结果是多张页面。不知道有没朋友遇到这个问题。 展现的效果大概是这个样子
UpdateMultiTabs 
UpdateMultiTabs_2 

当时用Coolite做测试遇到两个问题:

1. 传递给Tab的Url参数会莫名其妙的被添加上其他字符(到Coolite论坛上问了一下估计是bug)。正常情况下,google搜索url是这个样子:http://www.google.com/search?q=Hello   但因为Coolite在Tab的Url后面添加了某些字符,结果变成这样:http://www.google.com/search?q=Hellosfkjsdkfjskdf,  解决办法是把搜索Url设成这样形式:http://www.google.com/search?q=Hello&End=Y ,呵呵!!

2. 多个Tab同时加载页面引起冲突,导致后面加载的Tab页面有javascript错误。解决办法很简单,TabPanel的属性 DeferredRender="false" 就OK了。
