On the click of a submit button on any website eg. Amazon, I want a .html to be triggered using google extension. please let me know if it is possible.
You can indeed execute scripts on (almost) any page using content scripts that can manipulate the DOM, allowing you to add an onsubmit event listener to a form (more reliable than onclick on a button as it is fired however the form is submitted - e.g. hitting ENTER).
What exactly do you mean you "want a .html to be triggered"? Triggered in what way? If you want to open another tab when this happens, you can do this using message passing to tell your background page to do this for you using the chrome.tab.create API method.

I am trying to build a simple chrome extension so that when a form on a webpage in a specific website is populated and the user presses Submit then the data in the form is captured and then some of that data is injected into another form running on a different website.
I have no access to edit the code for either of the forms so a chrome extension seems to be the best way to do this from what I have read.
I would like to know if this is possible and how to go about it
It is possible using Content Scripts, a Background Page, and/or Chrome.storage
You will need Content Scripts on both websites that have the forms. Use the Manifest File correctly to set up which websites to attach which Content Scripts to.
The first Content Script (the one reading the form being filled and submitted) will have to take the values of each form input, triggered by the submit button.
Then you will need to use Message Passing to send a message (containing all the form data) from that Content Script to your Background Page. The data can be held temporarily or saved into chrome.storage by the Background Page.
Then the second form's Content Script also uses Message Passing to request the data from Background Page, which is delivered from temporary holding or retrieved from chrome.storage then sent.
And finally the second Content Script modifies its website's form to fill in the values.
Had a qq: is it possible to launch an extension (that is already installed) when someone clicks on a link ?
For example, let's say on my website I have a button that says "click here to launch the extension". After they install my chrome extension, when a user clicks on this button, could the extension launch? (e.g.- the popup to open).
The goal is this: I have an extension that acts like a search bar. I also have search on the website, but I wanted it to search using the extension instead of the website if a user chooses to.
Thanks for any info,
Y
If you are asking for a way to programmatically open the extension's popup, then you will be disappointed (as it cannot be done).
If it serves your purpose, you could do something like this:
Have your extension inject a content script into your webpage.
Have the content script bind to a button's click event.
When the button is clicked: Pass some parameters to the extension's background page, let the extension perform the search and send the results back to the webpage.
Whenever browser back is clicked, it must not navigate to the previous page but to some default page. how is it done using JSF ?
Clicking on browser back button requests the result page from the browser cache.
This is a client side activity. It doesn't send request to your server for fetching some default page(in your case).
Please refer this post for writing a filter indicating the browser not to cache dynamic JSF pages.
And also you can refer this one for more details.
You can try to detect if User has clicked on browser back button by writing client side code.
Refer this post for detecting back button click.
If you are trying to alter the behaviour of browser back button, it indicates some kind of flaw in your application.
I am making an extension for chrome. It fetches data from webpages and emails it via local email client. I have a toolbar button which user has to click to invoke the script.
My script works for a few selected urls. I want my toolbar button to change icon based on whether the url is among our list or not. For example for site1 it should be redicon.png and for site2 it should be blueicon.png. I can change button icon using chrome.browserAction.setIcon. But the problem is that this API does not work in content script. It works fine in the background.js file but not in content.js. Kindly tell me how to achieve this.
I know using pageAction instead would do the trick but my client requirement is that the toolbar icon should change rather than appear and disappear.
What you need to read about is message passing. You are right, content scripts have limited chrome API. However, you can contact background page from content script and tell it to execute anything from chrome API for you. First, you need to create a listener on a background page that will be waiting for messages and then send a message from a content script.
I had created a simple web part with one label, and one button. I wnat that when i click the button the label content will change.
But when i debugg i found that the focus is not going inside the Button Click Event function.
When i click the button the debugger will again start with page load.
Is there any Autofocus for Button.
Please help me to resolve my problem.
Thanks :)
I think that you're confused about what happens on the client (within the browser) and what happens on the server (in your ASP.NET code).
Most events on server-side controls, like the ASP.NET button, are handled server-side, through a mechanism called postback. The generated code on the browser causes a form submit to the Web server, where the page and its controls are re-created. The form data is parsed and the button control generates (in your case) a Click event for your server-side code. This code regenerates a new HTML page which will replace the old one.
Fortunately for you in this case, the ASP.NET button has a property "OnClientClick" where you can insert JavaScript code to do whatever you want (like change the label text) directly in the browser.
See MSDN for the docs on the property and an example of using both Click and OnClientClick.
Note that this is not related to SharePoint, this is a pure ASP.NET issue.
