 EasyUI is an 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.

In this article, we will learn how to design a validate box using jQuery EasyUI.  The validate box is designed to validate the form input fields.

Downloads for EasyUI for jQuery:

Syntax:

<input class="easyui-validatebox">

Properties:

  • required: It specifies that the field must be filled before submission.
  • delay: It specifies a delay to validate from the last input value.
  • missingMessage: This is the Tooltip text that appears when the text box is empty.
  • invalidMessage: This is the Tooltip text that appears when the content of the text box is invalid.
  • tipPosition: This defines the position of the tip message when the content of the text box is invalid.
  • deltaX: This defines Tooltip offset in the X-direction.
  • novalidate: This specifies whether to turn off validation.
  • editable: This specifies whether the user can type text directly into the field.
  • disabled: This specifies whether to disable the validate box.
  • readonly: This specifies whether the component is read-only.
  • validateOnCreate: This specifies whether to validate after creating the component.
  • validateOnBlur: This specifies whether to validate when losing focus.

Events:

  • onBeforeValidate: This event fires before the validation on a field.
  • onValidate: This event fires when validating on a field.

Methods:

  • options: Returns the options object.
  • destroy: Remove and destroy the component.
  • validate: Do the validation to determine whether the content of the text box is valid.

<script type=”text/javascript” src=”jquery.min.js”> </script>  

<!–jQuery libraries of EasyUI –>

<script type=”text/javascript” src=”jquery.easyui.min.js”>  </script>  

<!–jQuery library of EasyUI Mobile –>

</script>

    <meta charset="UTF-8"
    <meta name="viewport" content="initial-scale=1.0, 
        maximum-scale=1.0, user-scalable=no">

      $('#gfg').validatebox({
          required: true,
