由 孤者浪人 提交于 2019-12-21 19:56:55
问题 I'm trying to write a little greasemonkey script/bookmarklet/what have you for Google Docs. The functionality I'd like to add needs a keypress/keyup/keydown event handler (one of those three). Unfortunately, Javascript isn't my forté, and I can't seem to capture (?) a keypress event to while in the edit pane. As a last resort, I've tried the following: javascript:(function(){ els = document.getElementsByTagName("*"); for(i=0;i<els.length;i++){ els[i].onkeypress=function(){alert("hello!");};

问题 I'm trying to build a javascript bookmarklet for a special URL shortening service we've built at http://esv.to for shortening scripture references (i.e. "Matthew 5" becomes "http://esv.to/Mt5". The bookmarklet is supposed to do a GET request to http://api.esv.to/Matthew+5, which returns a text/plain response of http://esv.to/Mt5 . The code for the bookmarklet itself looks like this (expanded for readability): var body = document.getElementsByTagName('body')[0], script = document.createElement

How to inject script into a page using bookmarklet if the Content Security Policy is enabled on the server?

由 邮差的信 提交于 2019-12-19 04:08:07
问题 I have a bookmarklet which uses jQuery and parses some elements on the page. To use jQuery, i am creating a script tag(with src as the jQuery URL) dynamically and appending to the head tag. This works well for many sites. But, there are few sites like Facebook, for which the bookmarklet is not able to inject the external JS file into the dom.I came to know that this behaviour is because of the response header "Content Security Policy" which prohibits the inclusion of scripts from any other

问题 How can get the selected text from a textbox/textarea if I don't know which one active (focused). I am trying to create a small bookmarklet that will correct the selected text in any type of input on a page. 回答1: For the selection, you want selectionStart and selectionEnd . As for the currently focused element, use document.activeElement . So as a combination you can use: http://jsfiddle.net/rBPte/1/. As Tim Down pointed out, you'd need a more complex solution for Internet Explorer version 8

Find all text nodes

由 浪尽此生 提交于 2019-12-18 04:37:07
问题 I'm trying to write a bookmarklet that calls the function doSomething(textNode) on all instances of visible text on the document. doSomething() , just for fun, replaces every word with "derp" by replacing the textContent of the textNode passed into it. However, this makes some textNodes that are empty to have words in them, so it breaks the web page. Is there a way to call doSomething() on only every textNode that has words in it? function recurse(element) { if (element.childNodes.length > 0)
