How to get the key of a CustomData in SAPUI5? -

-

i access key of customdata, inside list.

xml view: 

<standardlistitem title="{name}" press="getselectedid" type="navigation">    <customdata>      <core:customdata key="{id}"/>    </customdata> </standardlistitem>

i can't pass id of standardlistitem {id} because integer, , reason, not allow. i've created customdata it.

so, whenever press list item key of item. here's exemple of i've tried it.

 getselectedid: function(oselected){               sap.m.messagetoast.show(oselected.getsource().getkey());                }

the messagetoast see if got right value.

unfortunately getkey() cannot used after getsource, or oselected

how can key of selected item?

calling oselected.getsource().data("key") should it. (for readibility better rename oselected oevent , give event handler name indicating handles event.)

javascript - Create websocket without connecting -

is there way create websocket without connecting right away? far think var ws = new websocket("ws://ws.my.url.com"); creates , connects right away. i'd create socket, define callbacks, , connect once user clicks connect button. thanks no. creating websocket means you've created connection server (or started process of connecting). there no such thing creating websocket isn't connecting yet. you create object store configuration parameters , tell object connect when wanted to, though i'm not sure why that's better creating actual websocket when connect made. or create function setup work , call function later when user clicks connect button.
