google chrome - Use `inspect an element` tool to make global Javascript variable -


in modern browsers (and firefox + firebug) can open developer tools , either go html/elements tab, or can inspect element interactive dom display.

you can heaps of useful stuff here, , 1 thing need manipulate/interact particular element using javascript (in console tab).

what i've been doing using interactive dom add id attribute 'bob', doing whatever need in console document.getelementbyid('bob') (or $('#bob')).

ideally i'd right click on element , select option make js variable in console can use variable called bob,
does know of such hidden feature/addon/faster method?

use built-in xpath context menu shortcut. here process:

  • right click on element within dom inspector tab
  • select copy xpath context menu
  • paste selector console
  • enclose selector in single quotes
  • enclose selector in $x() method of console api
  • append array index of selector match

  • append desired property/method reference

    $x('//*[@id="header"]')[0].innertext

vb.net - Virtual Keyboard commands -
