Scripting

一、In drivers which support it, you can easily execute JavaScript:

page.execute_script("$('body').empty()")
For simple expressions, you can return the result of the script. Note that this may break with more complicated expressions:

result = page.evaluate_script('4 + 4');
二、  page.execute_script("$('div:eq(0)').length")
     page.execute_script("document.getElementById('wrapper')")
