SAP OpenUI5 Hello World Example
To write applications, Need to download the runtime library as well as SDK. Both are required for running any application including mobile apps. The code can be deployed to any web server. For this sample application, We will use the CDN library for this example.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv='X-UA-Compatible' content='IE=edge' />
<title>SAPUI OpenUI5 Demo Applicaotn</title>
<script id="sap-ui-bootstrap"
src="https://openui5.hana.ondemand.com/resources/sap-ui-core.js"
data-sap-ui-theme="sap_bluecrystal"
data-sap-ui-libs="sap.ui.commons"
data-sap-ui-compatVersion='edge'>
</script>
<script>
var oBtn;
oBtn = new sap.ui.commons.Button({
text : "Button Sample Demo",
press : function (oEvent) {
alert(this.getText());
}
});
oBtn.placeAt("main");
</script>
</head>
<body class='sapUiBody'>
<div id='main'></div>
</body>
</html>
The above example has a button and on clicking this button, an alert is shown with content. This is a sample hello world example to show the cause OpenUI5 Code.
