Question

My validation message isn't working. how do you write this ?

Create a javascript validateSummary() function that displays the message “You must include a summary of the trip in your report.” if the validation state of the summary field value is missing; otherwise set the custom validation message to an empty text string.

Answer 1

function validateSummary(){

   

    // custom validation message

    var message = "";

   

    // if the validation state of summary field is present

    if (typeof summary.validation !== 'undefined') {

        message = "";

    }

    else{

        message = "You must include a summary of the trip in your report.";

    }

}
