Posted on by Chrisbra22

Hi, 
I am relatively green when it comes to JScript. I need to require a field (text) to have a minimum length of 8 characters.  Maximum length is already set at the field properties level.  
If field does not have 8 characters, it needs to display a message.  I am getting a script error on change of this field when using the following code.  I believe it has something to do with the XRM.Page line:

function FieldValidation(context)
{
var field = Xrm.Page.getAttribute("bf_DOT1").getValue();
if(field.length < 8) {
Xrm.Utility.alertDialog("Please enter 8 or more characters in field");
context.getEventArgs().preventDefault();
}
}

Can someone identify the correction that needs to be made here?  I then need to apply this to DOT2, DOT3, etc etc. fields on the form on change.  

Thanks!

    Hi Chrisbra22,

    Here you are

    function FieldValidation(executionContext) {
    let isValidate = false;
    try {
    let formContext = executionContext.getFormContext();
    let bf_dot1 = false
    let field = formContext.getAttribute("bf_dot1").getValue();
    if (field.length < 8) {
    formContext.ui.setFormNotification("Please enter 8 or more characters in field DOT #1", "ERROR", "bf_dot1");
    isValidate = true;
    bf_dot1 = true;
    }
    if (bf_dot1) {
    formContext.ui.clearFormNotification("bf_dot1");
    }
    if (isValidate) {
    executionContext.getEventArgs().preventDefault();
    }
    } catch (e) {
    Xrm.Navigation.openAlertDialog("Errors: " + e.message);
    }
    }

    OK great, thanks for that.  I have it working for DOT1 field.  But when I add in the rest of the fields it is not working.  No errors though...

    Do you think you could provide a sample in a snippet with the first 2 DOT fields?  I can take it from there!  Here is my code for DOT 1 that is working:

    function FieldValidation(executionContext) {
    let isValidate = false;
    try {
    let formContext = executionContext.getFormContext();
    let field = formContext.getAttribute("bf_dot1").getValue();
    if (field.length < 8) {
    formContext.ui.setFormNotification("Please enter 8 or more characters in field DOT #1", "ERROR", "bf_dot1");
    isValidate = true;
    }
    else{
    formContext.ui.clearFormNotification("bf_dot1");
    }
    if (isValidate) {
    executionContext.getEventArgs().preventDefault();
    }
    } catch (e) {
    Xrm.Navigation.openAlertDialog("Errors: " + e.message);
    }
    }

    But when I add in the second set for Field 2 (DOT # 2) it throws a Script error - web resource method does not exist:

    function FieldValidation(executionContext) {
    let isValidate = false;
    try {
    let formContext = executionContext.getFormContext();
    let field = formContext.getAttribute("bf_dot1").getValue();
    if (field.length < 8) {
    formContext.ui.setFormNotification("Please enter 8 or more characters in field DOT #1", "ERROR", "bf_dot1");
    isValidate = true;
    }
    else{
    formContext.ui.clearFormNotification("bf_dot1");
    }
    if (isValidate) {
    executionContext.getEventArgs().preventDefault();
    }

    let field = formContext.getAttribute("bf_dot2").getValue();
    if (field.length < 8) {
    formContext.ui.setFormNotification("Please enter 8 or more characters in field DOT #2", "ERROR", "bf_dot2");
    isValidate = true;
    }
    else{
    formContext.ui.clearFormNotification("bf_dot2");
    }
    if (isValidate) {
    executionContext.getEventArgs().preventDefault();
    }

    } catch (e) {
    Xrm.Navigation.openAlertDialog("Errors: " + e.message);
    }
    }
