I have created a code that gives me different standard answers i always use when i'm working. The code is simple but it will make me more efficient ...if is doable. The standard phrases have tag names and if i open the browser i'll get an "userBox", if i type in "moving" i'll get the phrase for that tag name. I've created a chrome extension that "matches": [""] but i want the tag names to be triggered and to give me the corresponding phrase automatically when i write an email. I have no experience with chrome extensions and i'm a beginner in js and html, is this doable for a beginner and if so i would really appreciate some help.
I am currently working on a similar project, the first task for you would be to get the contentEditable divs and textarea using querySelector, the divs and textarea inside iframe should be handled separately and listen for the changes made in the textarea. if you want to alter DOM or get something from DOM it should go in content scripts read more about it here in Chrome extension documentation and know the difference between content scripts and background scripts. Try starting with simple extensions like background-color changing extension to get the hang of it. JS for beginers might be confusing since its asynchronous, so I recommend doing some simple extensions first and get familarised with chrome extension API.

I am working on automating a process within my business, part of which is sending an email through SalesForce. We don't have access to the SF API and the email has to be sent through salesforce in order to keep the communication searchable for the coworkers.
I need to use a template which can be selected in SalesForce, however this function does not work in IE (which our RPA solution uses) so I need to build this email from scratch.
I see two options for this:
Use the HTML to recreate the format with the right variables. This entails inserting/injecting/manipulating HTML.
Copy the format into memory/the clipboard, edit it programatically and paste it into the SF interface
This question will be about option 1. I will post an additional question with regards to the second option separately and edit this question to include that link. EDIT: Here is the link to the other question!
Now on to the question:
We use the Blue Prism RPA software suite. It has a possibility to insert javascript fragments into a website and subsequently invoke them. I was hoping that I could create a javascript fragment that recreates the template, insert it and then invoke it. I have been working on this for the past week and have hardly gotten any further.
I now am able to add basic text into the required field, but have found that to be able to use the template structure I need to use a different, HTML based, field. This field I find lives inside an iframe.
I have had zero experience with javascript prior to this week (luckily it seems similar to c# in which I do have experience) and now this iframe has me stumped. Apparently when you use Selenium or similar you can switch the driver to the new iframe but I don't have that option, it needs to be done through surface automation. Within javascript as well as the console I can not get it to target the separate document within the iframe. Apparently the iframe contents are not incorporated in that way in the bigger webpage.
So my question is this: How can I "switch focus" to the iframe using javascript? How can I then edit the iframe contents through javascript? Any help, tips etc. would be highly appreciated!
If you go to developer tools in the browser (F12 or right-click inspect) you can use the inpsect tool to get the path you are looking for. an iframe is just another window inside the window and once you have the 'base path' you can then extend further into the window from the iframe base path.
You can access frames one of two ways I know of;
document.getElementById('the frame you are looking for goes here').contentWindow.targetFunction();
and/or
window.frames[0].otherfunctions
where 0 is the Nth order of frame on the window in case there are others.
once you find that path you can interact with sub-elements on that iframe by getting the path to it from within the iframe.
some things to watch out for. frames not loading yet so make sure the frame you want is loaded and no other frame is moving it around the screen at run time. Also make sure the child frame is in the same domain, I think calling javascript has issues when going cross-domain i.e. it doesn't work (stand to be corrected there though maybe it depends on group settings)
Supply some code or the layout of the page and could give you a code example but top of my head the format will look like this
var doc = window.frames[0]
var thing = getElementById(doc.getElementByPath('maybePath')
'perform some set operations like set innerhtml to thing you desire
I am using firebug to edit my magento theme. In a particular element I am getting an element.style attribute that I want to edit. Now how do I know which JS file is to be edited?
If you want to interact with elements via Javascript, you can use the console function in Firebug. Go to console, and click enable and from there you can start typing code as if it were javascript.
Example, if you wanted to check the z-index property of a specific element you could just type the javascript in the console:
document.getElementById("idOfElement").style.z-index
and when you hit enter it should tell you. You can also see errors in the javascript file if there are any.
If you are looking for the Javascript file of what is committing this change in the z-index property and you are 100% certain it is because of the Javascript, then you can use the debugger Firebug has which is also in the Scripts tab. If you're dealing with multiple javascript files, I'm not entirely sure how you can sift through which JS file is causing it, I believe you'll have to do that digging on your own. The debugger allows you step through your JS file though and see what changes are being made step-by-step.
Here is a tutorial on how to use the debugger if you're not familiar. Hope this helps.
Not sure about firebug,
But if you use linux you may try this command,
grep "element.style" -Rn .
Do you Want to change the Style or Something other.
If you want to change Style of a Particular Element, Just Follow the Steps
F12
Select Inspect Tool
Click on the Element where you want to change
In a FireBug Window look at Right and Make Sure style Tab is Selected
Just Single Click on value of a Particular Property

I'm creating firefox addon to add onclick event to the specific button. ("input" element)
The button is placed in http://example.com/welcome#_pg=compose
but when I open the page, following error occures:
TypeError: document.querySelector("#send_top") is null
#send_top is id of the button which I want to modify. So, the button is not found.
This error occurs because http://example.com/welcome and http://example.com/welcome#_pg=compose is completely different pages.
In this case, the addon seems loading http://example.com/welcome but there is no button whose '#send_top' ID.
When #_pg=compose anchor is added, the button is loaded by JavaScript.
How can I load http://example.com/welcome#_pg=compose to modify the button?
Three thoughts to help you debug this:
to correctly match the url you should consider using a regular expression instead of the page-match syntax - this might allow you to react to the anchors in a more predictable way
I've found that when using content scripts with pages that are heavily modified by JS, you can run into timing issues. A hacky workaround might be to look for the element you want and, if it isn' there, do a setTimeout for a 100 milliseconds or so and then re-check. Ugly, yes, but it worked for some example code I used with the new twitter UI, for example.
You can use the unsafeWindow variable in your content script to directly access the page's window object - this object will contain any changes JS has made to the page and is not proxied. You should use unsafeWindow with great caution however as its use represent a possible security problem. In particular, you should never trust any data coming from unsafeWindow, ever.
I'm a member in a website and there's a huge (automatically generated) HTML table on this PHP page that is only available to me and I wanted the table source code because I want to copy it to a HTML page on my computer to then process it with a program.
The problem is that when I right-click to display the page source code it works. However, I'm tired of looking at the source code and inside all the linked JavaScript files. I can't seem to find the table or any data of it on the scripts/page source codes.
I can select the table data and copy it, but it is just the data. It doesn't say anything about flash, so I'm assuming it's not flash. The data of the scripts/pages isn't obfuscated, it's easily human-readable.
I used Google Chrome's 'inspect element' and it worked.
I was thinking on doing a PHP script that would import data from a similar table, but I will have to know more about a lot of stuff mentioned here.
What can I be doing wrong or what can cause this kind of behavior?
Two possible reasons could be that the table may be returned from an AJAX call to another page that returns the HTML for the table, or they could be generating the table's html code and contents on the fly from a list of values coming from javascript or some other source rather than serving the HTML output to you from the server side.
Something you can do to figure it out is see if there are any empty div or other html elements where the table appears to be inserted, and search their javascript files for references to those elements. That may shed some light on how they populate it.
Feel free to update your question with the raw html (where you don't see the table) and maybe some javascript and we can look. Use pastebin if it is a lot of content.
Would it help to use the Firefox plugin called Firebug?
Using this plugin you can click on an area of a page to see the code displayed in the Firebug section at the bottom of your window.
Here are the details: https://getfirebug.com/whatisfirebug
Maybe the table is generated with a JS script, if that's the case, doing right click and "View source" would not show you the html. You need to use something like Chrome's devtools. Open google chrome and visit that page, once there, right click the table and select "Inspect element", the devtools will open and then you'll see the table's code, right click it's opening tag and select "Copy as html".
Let me know if that works :)
Try a developer extension like http://getfirebug.com/ The underlying source code may not reflect output due to how much the DOM can be modified by javascript with extensive use of ajax. This plugin will permit you to view elements as they're interacting with the browser.
its probably that the table is dynamically generated on the fly so looking at the source code won't actually give you much. try looking at the "GENERATED" source code or inspecting the DOM using Firebug, or the Developer tools of chrome/safari.
Or better yet, try your hand at web scraping:

Although I'm not sure if it'll work for pages that need a login. But hey, at least you learned something new :p
So, I've written a little javascript widget. All a user has to do is paste a script tag into the page, and right below it I insert a div with all of the content the user has requested.
Many sites do similar things, such as Twitter, Delicious and even StackOverflow.
What I'm curious about is how to test this widget to make sure that it will work properly on everyone's webpage. I'm not using an iframe, so I really want to make sure that this code will work when inserted most places. I know it looks the same in all browsers.
Suggestions? Or should I just build one hundred web pages and insert my script tag and see if it works? I would hope there is an easier way than that.
Once you have confirmed that your javascript works cross-browser in a controlled environment, here are some things that might cause problems when used on an actual website:
CSS
You're using a CSS class that is already being used (for a different purpose) by the target website
You're using positioning that might interfere with the site's CSS
The elements you are using are being styled by the website's CSS (you might want to use some sort of "reset" CSS that applies only to your widget)
HTML
You're creating elements with the same id attribute as an element that already exists on the website
You're specifying a name attribute that is already being used (while name can be used for multiple elements, you may not be expecting that)
Javascript
What is the expected behaviour without Javascript enabled? If your script creates everything, is it acceptable for nothing to be present without JS?
At very basic you should make sure your widget works for following test-cases. I am sure then it will work on all web-pages -
http/https: There should not be any warning for HTTPS pages for unencrypted content.
<script> / <no-script>: What if JavaScript is disabled? Is your widget still visible?
What happens when third-party cookies are disabled? Does your widget still work?
Layout-box restrictions: When parent div element's size is less than your widget. Does your widget overflow the given size and destroys owners page?
By keeping all your Javascripts under a namespace (global object) with a very unique name, you should be pretty much OK. Also, you can simply use an anonymous function if you just want to print out something.
