Using Sencha ExtJS to customise an existing website or do a mashup -


i'm using extjs 4.2.1 add customizations web site on have no design control. consider adding extjs components page mashup.

the problem when extjs starts adds css classes, such x-body, <body> element of dom , affects else on page. need able stop doing while still allowing take effect on extjs containers.

i know can use iframe contain extjs customization , isolate page's dom, found problems performance iframes, , rendering problems in firefox , ie need different solution.

in extjs 4.0.2 if set scoperesetcss:true magic happens, in extjs 4.2.1 can't found option.

i guess have couple ugly options:

  1. remove styles extjs stylesheet (a long , boring work)
  2. use ext.element , removeclass function manually remove class each element http://docs.sencha.com/extjs/4.2.1/#!/api/ext.dom.element-method-removecls
