						Presetting form fields with JavaScript in Dynamics 365 allows developers to programmatically populate default values in specific fields when a form is loaded.
// Prefill fields in Dynamics 365 formsss
function prefillFieldsOnNewForm(executionContext) {
    
    const formContext = executionContext.getFormContext(); // Get the form context
    const formType = formContext.ui.getFormType(); // Get the form type (1 = Create)
    // Check if the form type is "Create"
    if (formType === 1) { 
        // Prefill the text field
        formContext.getAttribute("pps_textfield").setValue("Default Text");
        // Prefill the integer field
        formContext.getAttribute("pps_integerfield").setValue(100);
        // Prefill the option set field (value must correspond to an existing option's value)
        formContext.getAttribute("pps_optionsetfield").setValue(1);
        // Prefill the date field with the current date
        formContext.getAttribute("pps_datefield").setValue(new Date());
    }
}
