[Solved] JS switch statement inside function

by


I’m not totally sure what you’re doing, but I suspect it’s something like this:

function filter(value) {
    switch (value) {
    case 'number is required':
        value="Number field is required";
        break;
    case 'something else':
        value="Some other message";
        break;
    // More cases here
    }
    return value;
}

$.each(response.errors, function(i, e) {
    msg = filter(e);
    $("#errors").append("<div class="error-msg">" + msg + "</div>");
});

The filter function returns the replacement message if it matches one of the cases. The caller assigns this return value to a variable, and puts it into the DIV.

Instead of a case, you can also use an object as a dictionary, which is my preferred method:

var translations = {
    'number is required': 'Number field is required',
    'something else': 'Some other message',
    // more cases here
};
function filter(value) {
    return translations[value] || value;
}
