Let’s build a straightforward screen that receives a name and shows an alert welcoming the user.
On OutSystems Service Center, drag and drop one input widget and a button to the screen.
Our input needs a variable to store the typed text. Thus, assign the input to the variable.
Next, the button needs an action triggered on the user’s click. Open it.
Double-click the node; write your script code in the placeholder.
For a simple demonstration, write a window alert.
Let’s now use the text input containing the end-user name.
Use that new argument on the code, concatenated to the text.
Open your app, write your name on the input field, press the button, and... we get a message.
All this, just using a simple JS node.
When developing an OutSystems reactive web app, you would expect to display data quickly, but it doesn't always happen. Do you know why? We'll explore the reasons and how to tackle them.
