Windows Phone 8 - Javascript : back button

问题

I need to handle the back button in HTML 5 - Javascript application for Windows Phone 8. I found a lot of solutions in C# but no one in Javascript. Does anybody know how to do this ?

回答1:

//Hardware back button could be handle using this.

 var hardwareButtons = Windows.Phone.UI.Input.HardwareButtons;
    hardwareButtons.addEventListener("backpressed", function (e) {
      e.handled = true; //handle back button event(won't close the app).
      history.back(); //go back to history
    });

Here is my code that work on windows phone 7 & 8

//WPback button handler methods
$(document).ready(function()
{
document.addEventListener("deviceready", setOverrideBackbutton, false);
});

function setOverrideBackbutton()
{
document.addEventListener("backbutton", backButtonTap, true);
}

/**
 * Callback after a backbutton tap on windows platforms.
 * Do nothing.
 */
function backButtonTap()
{
//Do not remove
}
