I am writing a chrome extension for capturing the URL. This is the code for my js file.
chrome.tabs.getSelected(null, function(tab) {
myFunction(tab.url);
});
function myFunction(tablink) {
alert(tablink);
}
Now i can get the URL alert for the page by explicitly clicking on the browser action. I need it to popup the alert whenever i click on any tab in my browser.
Could you please let me know how to proceed with this?
PS: I am sure i have to use some kind of event listener.
chrome.tabs.getSelected is deprecated since Chrome 33. Use chrome.tabs.query instead if needed.
Base on your need to make popup the alert whenever you click on any tab in your browser. You can use chrome.tabs.onActivated.addListener.
The code I created is as below and it works with me. It popup the alert of current page's url whenever you click on any tab in your browser.
chrome.tabs.onActivated.addListener(function(activeInfo) {
//alert("popup");
chrome.tabs.get(activeInfo.tabId, function(tab){
alert(tab.url);
});
});
Also keep in mind to add "permissions": ["tabs"], in your manifest file since it requires access to the url. See here:https://developer.chrome.com/extensions/tabs

As part of the functionality of the app we are developing, when an android alarm is fired, a dialog box is to appear with an "Accept" or "Reject" button. Selecting reject does nothing, but selecting "Accept" triggers a callback from the plugin, which I have passed a function into. This function causes the ionic app to navigate to the root page of the app.
The issue I am having is, when I then navigate to another page after that where the user selects a value, and this value is displayed back to them and a button is enabled, the value display is not updating, and the button is not becoming enabled. Nothing seems to be updating.
What I have found is that pressing the back button on my android device will cause the page to update, which is not ideal.
This functionality works without the callback from the plugin.
What is happening here? And how do I fix it?
Passing the function into the plugin.
alarms_plugin.onAlarmRecieved = (alarmId) =>{
this.events.publish('alarmRecieved', alarmId);
}
Plugin-side functions
alarmRecieved: function(alarmId){
alarms_plugin.onAlarmRecieved(alarmId);
}
onAlarmRecieved: null
Navigating to root page on alarmRecieved
this.events.subscribe('alarmRecieved', (alarmId) =>{
if(alarmId != 'TIMEOUT')
this.nav.setRoot(HomePage);
});
Fix found by surrounding the this.nav.setRoot(HomePage) in this.zone.run(..).
Supposedly calling navigation within a subscription event causes issues like I was having.
In one of my react components, I have this
<a href={'/application/' + username +'/' +appid}>My Application</a>
When I click on that link, I get the javascript error Accounts.ui.config: Can't set 'passwordSignupFields' more than once.
However, when I go to the directly to the url http://192.168.0.110:3000/application/john/X93ajdsfj by pasting the url into the browser address bar, then the page loads without errors. I only get an error when I load the page by click on the anchor tag.
I suspect that when I click on the link, I'm probably not doing a full HTTP page reload, and only parts are reloaded, and this javascript found in my myproject.jsx gets fired again:
// This code is executed on the client only
Accounts.ui.config({
passwordSignupFields: "USERNAME_ONLY"
});
I am completely new to meteor. What is the best way to avoid this problem?
I moved the code out of the React component and into the main .jsx file of the meteor project and wrapped it with a Meteor.isClient if statement like so:
if(Meteor.isClient)
{
// This code is executed on the client only
Accounts.ui.config({
passwordSignupFields: "USERNAME_ONLY"
});
}
My application has several popup windows opening from javascript validations. Sahi is not recognizing those. If I manually add it like
_popup("windowTitle"),
It says no such window found. The windows are not javascript popups but normal html pages opening as popups.
the exact error message is:
_popup("Error Window")._click(_button("CERRAR"));
Window/Domain not found: popupNameFromStep=Error Window; derivedName=; windowName=; windowTitle=Happy Time; wasOpened=0
Here the title it is recognizing is actually the parent window title.
What does the controller records it as? If it is a popup or a different window, the controller will record it correctly.
You can use the API _selectWindow which will use to select popup.
// switch to popWin popup window
_selectWindow("popWin");
// perform actions on popWin
_assertEqual("Link Test", _getText(_link(0))); // no mention of popWin needed
var $href;
_set($href, _link(0).href); // no mention of popWin needed
...
// switch back to base window
_selectWindow();
// perform actions on base window

Is there anyway i can get the hyperlink click in webview to my c# with Hyperlink value in Metro?. I am using WebView..NavigateToString() to generate the content?.
You can call InvokeScript with some of your own Javascript to set up a listener for when the user navigates away from your page. This would look something like the following in C#:
var navigationListenerString = #"
(function() {
function leavingPage() {
window.external.notify("LEAVING PAGE");
}
window.onbeforeunload = leavingPage;
})()";
webView.InvokeScript("eval", new string[] { navigationListenerString });
Then you can use ScriptNotify to listen for your particular message to determine that the page is unloading and the user is leaving. Unfortunately you cannot detect where a user is going. Also, if the hyperlink opens in a new window and the webview does not unload, you cannot detect that either.
Since WebView in windows 8 doesn't support Navigating() events like the Silverlight WebBrowser control, thus it is not possible to get hyperlink or cancel navigation.
But since you're using NavigateToString() method, you can write some manual javascript code and achieve same with the help of WebView.ScriptNotify() event.
I'm trying to pop open an apprequests dialog using the following cod:
$("#fbInviteButton").click(function(){
FB.ui({
method: "apprequests",
message: "Test"
};
});
When the button is clicked, a box pops up with the loader and just sits there. In the developer console in Chrome, I can see the ajax request complete and content come back.
When I look at the HTML source, I see the other dialog (class: "fb_dialog fb_dialog_advanced"), with populated content, and when I toggle the CSS for that window:
top: -10000px
the dialog with content comes into view.
So for some reason, when the content is loaded, it doesn't pop into place and replace the loader. Any idea what would cause this?
The application is Ruby on Rails using the Asset Pipeline.
I believe a bug in Facebook's JavaScript SDK causes this problem. I am currently using an older version of SDK taken from here as a workaround.
