Question

In yii framework of PHP I'm trying to append a textbox then initialise the datepicker. I already have two static textbox with datepicker working fine in the from and two more needed to be added and datepicker be initialised in those textbox.

When I'm trying to initalise after ajax success call. It is showing

My ajax call :

$.ajax({
            type: 'get',
            url: url,
            cache: false,
            dataType: 'html',
            success: function (html) {
                $('.append_more_parents:last').append(html);
                var num_form = parseInt($('.count').length + 2);
                $('.count:last').text('Parental Responsibility ' + num_form);
                $form = $('#appended_form');
                $form.replaceWith($form.html());
                container_id++;
                $('#datepicker').datepicker();
            },
            error: function (err) {
                bootbox.alert('Sorry adding of parental details failed! Please try again');
            }
});

如果显示“ datepicker不是函数”，似乎HTML页面中不包含Jquery datepicker库？
