Implement jquery Easyui tabs tab close icon after load custom event

When you close the Tabs tab in the project, the bottom footer need to reposition Calcfooter () via JavaScript, how do I do that? The Close icon on the tab is Easyui, Calcfooter () does not work in OnClose, there is no closed method in the API, but there is a method onbeforeclose before closing, In the Onbeforeclose method, implement the OnClose () method first, then Calcfooter (), and return false, so as to achieve the desired effect

The code is as follows:

$ (' #tt '). Tabs ({  onbeforeclose:function (title,index) {var target = This;var opts = $ (target). Tabs (' Options '); o Pts.onbeforeclose = function () {};  Allow now to close $ (target). Tabs (' Close ', index); Calcfooter (); return false;//block Close  }});
