SetClass Method (HTMLCONTROL)

10.9, PLBCMP GUI Only

The SetClass method changes the class attribute in a HTML element contained in a HTMLCONTROL object. The method sets the class attribute in the HTML element that has an id attribute that matches the id parameter. This method uses the following format:

Where:

label

Optional. A Program Execution Label.

object

Required. A HTMLCONTROL that is accessed.

return

Optional. A Numeric Variable that always returns zero.

Id

Required. A Character String Variable or literal that contains the HTML element id attribute.

value

Required. A Character String Variable or literal that has the value string applied to the {name} data type.

flags

Optional. A Numeric Variable or decimal value that specifies a bit mask value that controls the behavior of this method.

Flags Affected: OVER, ZERO

Note the following:

1. This method changes the class attribute value in a HTML element contained in a HTMLCONTROL object.

2. The ZERO flag is always set TRUE.

3. The OVER flag is always set FALSE.

4. The {id} is a value that determines the HTML element used for data changes. The {id} string is matched against the id attribute of the HTML element.

5. The valid values for the {value} parameter can be one or more class names separated by spaces.

6. The {flags} parameter is a bitmask value that forces specialized behaviors for the execution of this method.

7. The {return} value will always be zero.

Example:

For a HTMLCONTROL that contains a HTML element as follows:

<input type='text' class='myClass' data-plbenable='on' data-plbevent='change keypress click focus' maxlength=10 id='MyEdit'>

This PL/B SetClass method changes the class attribute value using the following instruction:

     HtmlControl.SetClass Using "MyEdit","MyNewClass"

In this example, the new HTML element is updated as follows:

<input type='text' class='MyNewClass' data-plbenable='on' data-plbevent='change keypress click focus' maxlength=10 id='MyEdit'>>
