Form Handling using EasyUI Framework

  • Last Updated : 05 Mar, 2021

The EasyUI is a HTML5 framework for using user interface components based on jQuery, React, Angular and, Vue technologies. It helps in building features for interactive web and mobile applications saving a lot of time for developers.

Download all the required pre-compiled files from the official website and save them in your working folder. Please take care of file paths during code implementation.

Official website for EasyUI:

Example 1: The following example demonstrates a simple user form with animated text fields with floating labels. Various classes that are specific to the EasyUI framework like easyui- panel, easyui-textbox, and easyui-linkbutton  are used for input controls.  For floating labels in the user form , form-floating-label class is used as shown below.

            }
            msg.html(message);
        }
    </script>
</body>
  
</html>

Output:

Example 2: The following example demonstrates the loading of local data and remote data. It also demonstrates the user form validation using EasyUI framework libraries. The same classes are used as in the above example. The class used for combobox is easyui-combox. Refer the output image or video for better understanding.
