We have a table which has two columns. We want to remove the tabindex from the first column, and the css class of the column is "readonlytext". How can I get the elements of the class "readonlytext" and remove the tabindex from it?

We have implemented it as below, but it doesn't work. 

pega.u.d.attachOnload(function(){ $('.readonlytext').removeAttr("tabindex"); }, true);

Thank you in advance,

Yudie
