My app has a long listview of a maximum of 99 entries. Each one has an image. A top and bottom fixed bars.
I decided against using pull to refresh since the display got very slow and displayed empty items for a second before showing them.
I face 2 problems :
- the list is quite slow. Especially on the first scroll. It is much faster once I have scrolled to the bottom and come back to the top but I can't expect the users to do that each time
- Each item has an image (with a default background image). Sometimes, the browser doesn't wait for long enough and shows a broken image (with a ?) instead of waiting for the image to show.
How can I increase the waiting time before a (?) shows up ? Is it possible to tell iscrollview to only fetch images on the part of the list currently displayed ? Is it possible to not display the (?) at all and if the image cannot show up, just keep the background image ?
PS: I use JQM 1.3.1 and Iscrollview 1.3.1
Thank you.
