Understanding Parameters

[sgsims]

Can someone provide an "Upper Level" explanation of Parameters? I am trying to understand the difference between accessing "elements" and passing "parameters". Are "parameters" a Caspio thing while accessing elements is a JavaScript thing?

Hi,

To make it simple, 'parameter' is a special kind of variable, used in communicating between different part of programs. It is wildly used in any computer programming. Caspio Bridge parameter is the same. You can pass it between different DataPages, or between a DataPage and outsource apps. Please check out our knowledgebase posting on introductions and usage of 'parameters' at http://help.caspio.com/categories/Parameters/

Regarding the 'access elements', in Caspio an form element can refer to any object on a DataPage. For example, a text box, a radio button, a dropdown or list box, or even a label, a button can be called an element. You can 'access' an element in many different ways. For example, you access the form elements by filling in a Web Form. Specifically, it is also possible for you to 'access' form elements by using JavaScript code if you would like to perform certain actions which are not offered in standard feature but can be done by using JavaScript. Here you can check the JavaScript solutions viewforum.php?f=14 and learn how JavaScript works with Caspio.

Hope this helps.

Thanks for the information! I'll read through the Parameters section of the online help.
