Question

I used to have a code that checks any previous element with a corresponding css class and an attribute which is…

var previousEl = el.prev('.line[@id]');
where line is a class and id is an attribute

this code worked in Ext but when I tried running the same code in sencha-touch, I get a “Error: SYNTAX_ERR: DOM Exception 12”.

I checked the dom and I have verified that there is a previous sibling with the class and the attribute id.

Can somebody help me out as to why this selector does not work anymore?

Thanks in advance.

Try dropping the @? They took it out from jQuery at some point of time, and reading the Sencha docs it would seem that they did the same in Ext JS.

var previousEl = el.prev('.line[id]');
