Below is the code snippet to set the requirement level (i.e., Required/Non-Required) of a field using script in portals. This logic handles all kind of field types including Check boxes.

Set Field As Required:

function SetFieldAsRequired(fieldName) {
if (typeof (Page_Validators) == ‘undefined’) return;
if ($(“#” + fieldName) != undefined && $(“#” + fieldName + “_label”) != undefined) {
$(“#” + fieldName).prop(‘required’, true);
$(“#” + fieldName).closest(“.control”).prev().addClass(“required”);

// Create new validator object
var Requiredvalidator = document.createElement(‘span’);
Requiredvalidator.style.display = “none”;
Requiredvalidator.id = fieldName + “Validator”;
Requiredvalidator.controltovalidate = fieldName;
Requiredvalidator.errormessage = “<a href=’#” + fieldName + “_label’>” + $(“#” + fieldName + “_label”).html() + ” is a required field.</a>”;
Requiredvalidator.initialvalue = “”;
Requiredvalidator.evaluationfunction = function () {
var fieldControl = $(“#” + fieldName);
if (fieldControl.is(“span”)) {
var value0 = $(“#” + fieldName + “_0”).prop(“checked”);
var value1 = $(“#” + fieldName + “_1”).prop(“checked”);
if (value0 == false && value1 == false) {
return false;
} else {
return true;
}
}
else {
var value = $(“#” + fieldName).val();
if (value == null || value == “”) {
return false;
} else {
return true;
}
}
};

// Add the new validator to the page validators array
Page_Validators.push(Requiredvalidator);
}
}

Set Field As Non Required:

function SetFieldAsNonRequired(fieldName) {
if (typeof (Page_Validators) == ‘undefined’) return;
if ($(“#” + fieldName) != undefined) {
$(“#” + fieldName).closest(“.control”).prev().removeClass(“required”);
$(“#” + fieldName).prop(‘required’, false);

for (i = 0; i < Page_Validators.length; i++) {
if (Page_Validators[i].id == fieldName + “Validator”) {
// Remove the current field’s ‘Required’ validator from ‘Page_Validators’ array
Page_Validators.splice(i);
}
}
}
}

How to use the functions:

• Above functions can be called from ‘Custom JavaScript’ tab of Portal’s ‘Entity Form’.
• Pass the Dynamics field’s schema name as the parameter to both functions.
  • In below example, ’emailaddress1′ is the field name which I want to set the Requirement level.

Refer the article for Portal script syntax’s and usage.
