哪些插件用于在Google Chrome浏览器中查找定位器？

Question

Hi i am new to Selenium WebDriver. i have some small doubts. (1). In Firefox Browser we used to find locators by Firebug plug-ins. Likewise is there any options for Google Chrome Browser. (2). Which locator is much fast while executing the scripts.

Answer 1

As mentioned in comments, hit F12 for Developer tools.

$x("//div[@id='myId']")

If content is in an iFrame, first find the iframe element and pass that as a second parameter:

myframe = document.getElementsByTagName("iframe")[0].contentWindow.document.body;
$x("//div[@id='myId']", myframe)

CSS selectors can also be checked by using:

$$("#mycssSelector")
