In this example I am showing how to create a running clock sync with client machine's clock. This is very small example, but very useful to make application user friendly. No third-party js library is required. Just a small js will suffice this requirement. Here is the example:
In your application create a place to show clock, then in index.html you just write this function to set test in that place:
<script type="text/javascript"> function getCurrentTime() { var Digital = new Date(); var hours = Digital.getHours(); var minutes = Digital.getMinutes(); var seconds = Digital.getSeconds(); var dn = "AM"; if (hours > 12) { dn = "PM"; hours = hours - 12; } if (hours == 0) hours = 12; if (minutes <= 9) minutes = "0" + minutes; if (seconds <= 9) seconds = "0" + seconds; var sLocale = sap.ui.getCore().getConfiguration().getLanguage(); sLocale = "DE"; var time = Digital.toLocaleTimeString(sLocale); var date = Digital.toLocaleDateString(sLocale); if (sap.ui.getCore().byId("idMenuClock")) { sap.ui.getCore().byId("idMenuClock").setText(time); sap.ui.getCore().byId("idMenuClock").setInfo(date); } setTimeout("getCurrentTime()", 1000); } getCurrentTime();</script>Here idMenuClock is the id of the button where I am showing time as text of that button and date as Info.
