Text Formatting Windows Store Apps

Introduction

In this article I describe how to create Windows Store Apps for formatting text using JavaScript. If there are a small number of settings contextual to a particular object in the app rather than the app itself, then use a fly-out to commit those settings. Changes should be reflected as soon as the user makes a change.

I assume you can create a simple Windows Store App using JavaScript; for more help visit Simple Windows Store Apps using JavaScript.

To start the creation of the apps, add one JavaScript page by right-clicking on the js folder in the Solution Explorer and select Add > new item > JavaScript Page and then provide an appropriate name. In the same way, add a HTML page to your project.

Write the following code in the default.html:

<!DOCTYPE html>

<html>

<head>

</head>

</div>

</div></center>

</body>

</html>

Write the following code in the default.js:

(function () {

"use strict";

var appTitle = "Flyout control app";

var pages = [

{ url: "page.html" }

];

function activated(eventObject) {

if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) {

eventObject.setPromise(WinJS.UI.processAll().then(function () {

var url = WinJS.Application.sessionState.lastUrl || pages[0].url;

return WinJS.Navigation.navigate(url);

}));

}

WinJS.Navigation.addEventListener("navigated", function (eventObject) {

var url = eventObject.detail.location;

var host = document.getElementById("contentHost");

host.winControl && host.winControl.unload && host.winControl.unload();

WinJS.Utilities.empty(host);

eventObject.detail.setPromise(WinJS.UI.Pages.render(url, host, eventObject.detail.state).then(function () {

WinJS.Application.sessionState.lastUrl = url;

}));

});

WinJS.Namespace.define("App", {

appTitle: appTitle,

pages: pages

});

WinJS.Application.addEventListener("activated", activated, false);

WinJS.Application.start();

})();

Write the following code in the page.html:

<!DOCTYPE html>

<html>

<head>

</head>

<body>

<p>

Click the "change color" button to launch the output.

</p>

Change Color</button>

</div>

</div>

Text color</label>

<br />

<option value="black">Black</option>

<option value="green">Green</option>

<option value="purple">Purple</option>

</select>

<br />

Size</label>

<br />

</div>

</body>

</html>

Write the following code in the default.html:

(function () {

"use strict";

var page = WinJS.UI.Pages.define("page.html", {

ready: function (element, options) {

document.getElementById("formatTextButton").addEventListener("click", showFormatTextFlyout, false);

document.getElementById("textColor").addEventListener("change", changeColor, false);

document.getElementById("textSize").addEventListener("change", changeSize, false);

}

});

function showFormatTextFlyout() {

var formatTextButton = document.getElementById("formatTextButton");

document.getElementById("formatTextFlyout").winControl.show(formatTextButton);

}

function changeColor() {

document.getElementById("outputText").style.color = document.getElementById("textColor").value;

}

function changeSize() {

document.getElementById("outputText").style.fontSize = document.getElementById("textSize").value + "pt";

}

})();

Output:
