ExtJS网格分页不起作用

Question

I am new to extjs and trying to get the grid pagination working on for a project.

Can anyone tell me if there is an online tutorial to setup pagination for extjs grid? I am getting the records for the first page but no on clicking the next button.

It would be great if some one can code or specify what code changes are required to get the next set of results.

Any help will be really appreciated!!

For an example check out http://docs.sencha.com/ext-js/4-1/#!/example/grid/paging.html

The service that example uses can be seen here: http://www.sencha.com/forum/topics-browse-remote.php?&page=3&start=100&limit=50&sort=lastpost&dir=DESC

Note that Ext JS Paging Toolbar adds the page, start, limit and sort params to the URL.

Your java code will need to reference these and use them in your SQL query.

A Spring controller might have something like this which will allow you to access the query params later in the method:

@RequestMapping(value = "/listTopics", method = RequestMethod.GET)
public ModelAndView listTopics(
        @RequestParam(value = "start", required = false, defaultValue = "0") Integer start
        @RequestParam(value = "limit", required = false, defaultValue = "10") Integer limit
        ) {

... }
