Tabbar attachHTML


#1

In DHTMLX 5 version, tabbar.attachURL(); I used a function to call the page.
However, in DHTMLX 7 version, tabbar.attachURL(); no function

tabbar.getCell(id).attachHTML("<iframe style='height:100%; width:100%; border:0px;' src='"+obj.URL+"' />"); 

to call the page using .
What I’m wondering is, is there a way to keep the previous tab data when the tab is moved when the page is called using attachHTML.
Currently, whenever you move a tab, the page is called again and the data you were working on disappears.
Is there any way?
