Validating textarea javascript

To learn more, see the documentation on Java Script's Reg Exp and read this tutorial on regular expressions.Process Maker provides some example regular expressions which can be inserted into the validate property.Changes will be shown when the form is rendered inside the preview or when running a case. This property defines the maximum number of characters which can be input into a text control field.This property is also a validation made over these fields, but if a regular expression has been set inside the "Validate" property, this validation will be verified first before the Max. Theoretically the property definition allows a maximum of 9,999,999,999 characters to be entered into the field, but the web browser probably will not have enough memory to handle that amount of input.In the example, the field "Result" will show the result of the multiplication between "Value 1" and "Value 2".Nevertheless, take into account that the formula must be made using the ID of those text controls, then the formula to be entered would be: When running a case, the fields that have configured a formula are disabled to input text.Furthermore, Process Maker can only store up to 16MB of data about a case, which would be 16,777,216 characters (assuming there are no international characters which need more than 8-bits).On a practical note, it is better to use textareas and file objects to store large amounts of data, since they are stored separately in the database and will not slow down the processing of Process Maker, nor are they subject to the same space limitations as textboxes.

To add this control to the Dyna Form design, drag the icon below from the Web Controls panel at the left, onto one of the rows in the Dyna Form design.

The results of the mathematical operations are shown as the values are entered in the fields included in the formula.
