Question

I am using the following:

var items = $.map(json.errors, function (error) {
return error + '</br>';
}).join(''); 

json.errors can be IEnumerable<string> or just string.

When json.errors is IEnumerable then items is populated with text with a <br> between each error message. However when json.errors is a string then items is populated with the error string with a <br> after every character of the string.

Is there some way that I could fix the problem for when json.errors is just a plain string?

Answer 1

As your current code adds a <br/> after every string, and not just between strings, this would be equivalent:

if (typeof json.errors === "string" ) {
    json.errors = [ json.errors ] ;
}

// continue as before
