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')")
     page.execute_script("document.getElementsByTagName('body')");
     page.execute_script %Q{ $('li').eq(1).trigger("mouseenter").click(); }
三、selenium+capybara 获取svg tag 里的元素
    eg1：  page.execute_script("$('svg image:first').click();")
    eg2： $('svg image:first').get(0));
    eg3：page.execute_script("$('#editTableDialog_priv_tab_0').find('span:eq(1) .privName').trigger('click').find(':text').val('考勤权限');")
