You may have also read her articles in Xojo Developer Magazine. Stefanie Juchmes studies Computer Science at the University of Bonn. If you have any questions, please do not hesitate to contact us. I hope that you like our new JavaScript functions. ![]() And you may find it useful to perform JavaScript server side for your Xojo web apps. If you get a JavaScript snippet, you can just run it, if required dependencies are provided. A great use for this JavaScript is to do calculations in your applications to match the hash/signature algorithm used by a web service to authenticate. Once the JavaScriptEngineMBS object is initialized, you can store it in a window property and reuse it several times to do more calculations. R = js.CallFunction("distance", lat1, lon1, lat2, lon2) The formula for the calculation is y = x * Pi / 180.Ī JavaScript function for that looks like this: function DegToRad( deg ) " Because that we need a function that converts between angle and radiance since we have the coordinates in the unit angle. Then we look at the JavaScript code.įor the calculation we need the longitude and latitude in the unit radiance. Furthermore we need a label that shows the result of the calculation and a button to start it. Two fields contains the longitude and latitude of the first coordinate, two other fields store the longitude and latitude of the second coordinate. In this example, I’ll show you a JavaScript that calculates the difference between two geo coordinates given by longitude and latitude. Because you can use JavaScript code in your Xojo projects, you not need to convert an existing JavaScript function to Xojo syntax to use it directly in your projects. This example is based on one of his JavaScript codes. Special thanks to André Rinas whose site supplies very useful JavaScript snippets. So start a search engine and try your luck. Perhaps someone has already found a solution to this problem and shared the solution on the Internet. If you have a problem that you want to solve, you don’t have to reinvent the wheel again and again. f figure (WindowKeyPressFcnfigureCallback) plot (1:10) Run the code and press +. Then, plot some data in the current figure. ![]() This callback executes when a user presses a key in the figure window. In the newest version of the MBS Xojo Plugin 10.0 we offer functions for the use of JavaScript in your Xojo solutions. Use the operator to assign the function handle to the WindowKeyPressFcn property of the figure.
