how to grab a fields data from inside an iframe?

Question

I am trying to pull data from inside an iframe that links to http://www.w3schools.com/ . I keep getting errors that won't allow me to pull out the data of any field or grab the entire page's html and put it into a variable.

I have already tried:

$('iframe').html();

I have also tried not loading it in an iframe so it could be accessed easier, but that also didn't work.

 $(function(){
          $("#includedContent").load("http://www.w3schools.com"); 
        });

要从iframe主体获取内容，您应该使用：

$("iframe").contents().find('body').html();
