问题 I have a jqgrid displaying a large amount data. The data is retrieved from the server periodically via a jquery ajax call (outside of the jqgrid logic). The retrieved data is compared to the data previously retried ( and stored as a var in js. it is served as the data for the jqgrid). if they are different the local data is refreshed, then trigger the jqgrid to reload. the jqgrid datatype is jsonstring. This solution is working quite well, except when the user have a filter value in the

问题 I have an image in my app (android) taken from an URL: <img src="URL"/> If i change the image on the server (keeping the same URL), the app does not refresh and keeps always the old image.

Enforcing the reload of the page seems a bit

问题 I am using a datagrid. It has itemEditor components, combo boxes, etc. as aprt of columns. Ideally datagrid.invalidateList() method works to reload the datagrid with new dataProvider data. But, for me it is appending to the old data and new data gets added below the older data. I am not able to fix this reload of datagrid. 回答1: Use ArrayCollection, not Array! ArrayCollection provides all the change notification machinery you need. Array does not. 回答2: I'm having a little trouble understanding
