jquery

问题 I am using jquery to write true and false strings to data- html attributes. However when I write false to one of the attributes, and then check it it false, it returns true.

问题 I wonder if it is possible to get the page title of an url within IFRAME. I tried to use jQuery $('#iframe').attr('title') but that doesn't work. Please help.
