Tree change arrow icon on the fly

[sky-t]

Hi there,

is ist possible to change the arrow icon of tree on the fly (I am sure you have solution for this)?

I want to realise an request to a websocket and wait for the response. While waiting for the response i want to show a waiting icon and after received the result from the websocket change back to the arrow icon.

Thank you for your Help!

The tree has the builtin lazy loading functionality. Please look at this example.

If you are using the combotree component, please call this line to show the loading icon.

Code:

$('#ct').next().find('.combo-arrow').addClass('pagination-loading');
<input id="ct" class="easyui-combotree" ...>
