Clear Selected Text In Javascript

July 9, 2015 by blogmeister·0 Comments

User Tim Down of the Stack Overflow forum provided a very simple Javascript code to clear selected text. This should work in all major browsers.

function clearSelectedText() {
    if (window.getSelection) {
        if (window.getSelection().empty) {  // Chrome
            window.getSelection().empty();
        }
        else if (window.getSelection().removeAllRanges) {  // Firefox
            window.getSelection().removeAllRanges();
        }
    }
    else if (document.selection) {  // IE?
        document.selection.empty();
    }
}

function clearSelectedText() {

if (window.getSelection) {

if (window.getSelection().empty) { // Chrome

window.getSelection().empty();

}

else if (window.getSelection().removeAllRanges) { // Firefox

window.getSelection().removeAllRanges();

}

else if (document.selection) { // IE?

document.selection.empty();

}

Remove Android Notification After Tap Or Click

February 1, 2012 by blogmeister·0 Comments

I recently added a notification feature for my widget and what I wanted was whenever the user clicks or taps the notification message in the notification center, it will remove itself rather than having to click the clear all button.

The secret lies in the flags of the Notification class by using Notification.FLAG_AUTO_CANCEL. However, to ensure that this works, the code has to be bitwise-or the flags like this

Notification notification = new Notification(R.drawable.icon, "Title", "This is a message", System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;

1 2	Notification notification = new Notification(R.drawable.icon, "Title", "This is a message", System.currentTimeMillis()); notification.flags \|= Notification.FLAG_AUTO_CANCEL;

Pretty easy, right?
