For each request, Blackboard Learn is responsible for verifying that the code processing these requests contains the correct values.
Through rulesets, the Input Validation Filter outlines a series of well-defined data fields within Blackboard Learn (for example, the Course ID field) and explicitly lists criteria and patterns that are acceptable entries for each field. If data entered does not match the rule criteria, the system reacts to this according to the value set up for the "on-fail" attribute.
This feature provides you with cross-site scripting fixes much faster than the traditional patching process.
Traditional patches can have various dependency issues or may need to be rolled back.
For production applications, developers often end up spending a lot more time and code on this task than we would like. NET page framework, it was important to try and make the task of validating input a lot easer than it has been in the past.
In HTML 3.2, validating data is a difficult process.
Name is read-only property that can be assigned to any input of the form/ htmlform. Such function takes the validated value as parameter.
You can do this either within rules object property of the form component: Per Item Validation with Predefined Rules Component Data Validation Here you need to define which data item you'd like to validate, namely specify its template #value# or, in case of datatable, column ID. Validation rules may define the minimal and maximum value for the form field or check whether the input data complies to a certain criterion.
A single Blackboard Learn instance can process many application HTTP requests daily (such as submit assignment, save assignment, log in to the system, log out of the system, and so on).
Drag one Text Box control and give it an ID of First Name Text Box, two Button controls (Submit Button and Cancel Button), and one Required Field Validator (First Name Required Field Validator). The following screen shows the form in action, and the user has pressed the Submit button without entering any text into the textbox. The Required Field Validator fails when the value in the associated control matches the value of the Initial Value property of the Required Field Validator.
This Required Field Validator forces the user to enter text into the control associated with the validator. If you want to make sure the user changes a default value placed into the control, set the control’s Text value and the Initial Value property of the Required Field Validator to the same value.
All you need to do is to specify the Input Description at the Bottom Additionally, a custom message can be set to handle validation process. Webix message can be used together with the validate() method within the sumbit_form custom function; 'on Validation Error' Event Message boxes of all types are described here.
The validate() function checks if data complies to certain rules defined in the rules object that contains a collection of property-rule pairs.
