HTML DOM Navigation Chrome 插件, crx 扩展下载

                    
HTML DOM Navigation lets you view the node tree in a simple and easy way. IRB would be really useful for Watir automation.
I have developed this extension mainly for fetching the DOM quickly since it might take some time in the Watir automation. 

-Click on the ‘HTML DOM Navigation’ icon at the right top of the page once the webpage loads completely
-Hover the mouse over any element in the page to view the IRB format and the top five ancestors of an element
-Right click on the page and select the ‘HTML DOM Navigation -> Tree Format’ option in the Context-Menu to view the tree format (of an entire body tag)
-To disable, click on the icon again

**You can copy the content using ‘ctrl+c’
**You can scroll the content using up-arrow and down-arrow 
Note: If the copy/scroll doesn’t work, click anywhere on the page to focus on it and try again
