    Hi,

    Here is a sample for you. The logic is that it won't allow to enter date of birth if the person is not male.

    function SetTheFieldState(executionContext){
    //Get the form context
    var formContext = executionContext.getFormContext();
    var Gender = formContext.getAttribute("new_gender").getValue();
    if(Gender === Male){
        //Set field as Editable
        formContext.getAttribute("new_dateofbirth").setDisabled(false);
    }
    else {
        //Set field as Read only
        formContext.getAttribute("new_dateofbirth").setDisabled(true);
    }
}

    Note: Make sure pass execution context checkbox is checked for the function register.

    If you need more details on Client API reference, you can refer to: https://docs.microsoft.com/en-us/powerapps/developer/model-driven-apps/clientapi/reference

    I hope this helps. Please let me know if you have any questions/concerns.

    Thanks

    Jay

    Thanks Jay. There ae multiple fields on form. how can i check whether few fields are available in the form using javascript.

    for example

    1. phone and email are in one form

    2. fax and primaryid in another form

    3. address and state in another form

    how to check that field is on form using javascript? The code should run and not fail because a field is missing

    Hello,

    If the field is not on the form then

    formContext.getControl("fieldschemanamehere") returns null

    so in order to satisfy your requirement you can use syntax that is similar to following:

    function setFieldDisabled(formContext, fieldName, isDisabled) {

    var fieldControl = formContext.getControl(fieldName);

    if (!fieldControl) {

    return;

    }

    fieldControl.setDisabled(isDisabled);

    }

    and here is an example on how to use that function:

    setFieldDisabled(formContext, "telephone1", true);

    setFieldDisabled(formContext, "emailaddress1", true);

    ...e.t.c.

    For JavaScript, it is necessary for you to know which field belongs where. You can pull up a field from different form by using following syntax:

    var quickViewMobilePhoneControl = formContext.getControl("contactQuickForm_contactQuickForm_contact_mobilephone");
if (quickViewMobilePhoneControl.getAttribute().getValue() == null) {
    quickViewMobilePhoneControl.setVisible(false);
}

    For more details you can read it here

    Please mark my answer as verified, if that helped you solved the original question asked.

    Thanks

    Hello,

    You can use array of fields and looping through it disabling/enabling it. Something like following:

    var allFields = ["field1", "field2", "field3", ....];

    for (var i = 0; i < allFields.length; i++){

    setFieldDisabled(formContext, allFields[i], true/false);

    }

    If you don't want to check it for all 30 fields you can simply do the following instead of adding the if statement.

    function SetTheFieldState(executionContext){
    //Get the form context
    var formContext = executionContext.getFormContext();
    var Gender = formContext.getAttribute("new_gender").getValue();
    console.log(Gender);
    if(Gender === Male){
        //Set field as Editable
        formContext.getAttribute("new_dateofbirth").setDisabled(false);
    }
    else {
        //Set field as Read only
        formContext.getAttribute("new_dateofbirth").setDisabled(true);
    }
}

    And you can see what value is added to the console using developer tools in your browser. Console.log helps you to debug the issue, if the field is not found it will also give you an error.

    Did you look at the approach I mentioned your earlier?

    Please let me know if you have any questions/concerns. I am happy to help you.

    Thanks

    Jay
