First of all, if you haven't already, digest the documentation on mixins: http://tapestry.apache.org/tapestry5/tapestry-core/guide/mixins.html
If you're clear on that, then the only piece you're missing is how to connect JS to the grid. For that your mixin should instantiate a JS object and be passed the client side DOM id of the grid. From there it's in the hands of your JS code. Have a look at the Autocomplete mixin source, or at these: (line 67) http://code.google.com/p/tapestry5-components/source/browse/trunk/commons/src/main/java/org/apache/tapestry/commons/components/SlideShow.java (line 78) http://code.google.com/p/tapestry5-components/source/browse/trunk/commons/src/main/java/org/apache/tapestry/commons/mixins/Resizable.java The first is a component, the other is a mixin. This doesn't matter as the process for connecting JS to the generated element is the same. See those indicated lines? That's the glue. Study that for a bit and see if you can make some progress. chris 滕训华 wrote: > Thanks for your reply. > > But how to control the tapestry grid component using javascript,can you give > a example or some materials. > > -----邮件原件----- > 发件人: Chris Lewis [mailto:[EMAIL PROTECTED] > 发送时间: 2008年4月10日 13:42 > 收件人: Tapestry users > 主题: Re: Who can give me some ideas about extending grid component > > Yes, you can easily do this with javascript and WITHOUT extending the > grid by using a mixin. > > chris > > > 滕训华 wrote: > >> Hi,erveryone,I want to know whether can I extend the grid function in 5.0. >> > I > >> want to add the follow action:if I select a row of the grid then I change >> the backcolor of it or double click the row to display a detail page.These >> functions can be finished by extend the grid through my javascripts and >> > how? > >> >> >> >> >> >> >> > > -- http://thegodcode.net
