Display parsley errors in bootstrap tooltip

问题:

I'm using parsley 2.0.0-rc5 and want display the error messages in a bootstrap tooltip. I'm using "parsley:field:error" but the event fires before the error is displayed in error-container and I can't pick up the error. Someone an idea how I get the error message for each field?

$.listen('parsley:field:error', function (e) {

    dataParsleyId = e.$element.attr('data-parsley-id');
    errorMsg = 'Error: ' + $('#parsley-id-'+dataParsleyId).text();

    e.$element.attr('data-original-title', errorMsg);
    e.$element.tooltip('show');

});

Guillaume Potier, the author of parsley, has added a ParsleyUI.getErrorsMessages(parsleyFieldInstance) method that will return an array of messages errors. It is available on master branch in github and would be released in next stable version.

This works perfectly for me and this is my sample code:

window.Parsley.on('field:error', function (fieldInstance) {
    fieldInstance.$element.popover({
        trigger: 'manual',
        container: 'body',
        placement: 'right',
        content: function () {
            return fieldInstance.getErrorsMessages().join(';');
        }
    }).popover('show');
});

window.Parsley.on('field:success', function (fieldInstance) {
    fieldInstance.$element.popover('destroy');
});
