动态更改工具提示自定义类

Question

我想根据用户在特定输入字段上提供的数据来动态更改data-custom-class（即，如果用户不为“ username”提供至少1个字符，则工具提示必须为红色并带有一些文本，如果用户提供）有效的“用户名”，工具提示必须为绿色，并带有其他一些文字。

问题在于文本实际上正在改变，但类却没有改变（它保留了JQuery设置的第一个类。

我已经尝试过attr（）和tooltip（options）-（即通过attr（）的“ data-customClass”或通过tooltip（）的customClass）。如您所见，我什至试图强制处理工具提示，并在再次设置属性之前先删除属性，但这似乎都不起作用。

Tooltip会创建一个新的“ div”，即使它更改了“ text”属性，“ custom-class”属性也不会。

注意：我正在使用Bootstrap 4 + Popper.js + Bootstrap自定义类（Js + CSS）扩展。 extension files link here

如果您对此有任何建议，我将不胜感激！

先谢谢。

            $('#username').attr("data-custom-class", "tooltip-success");
            $('#username').attr("title","Username avaiable!");

Answer 1

要更改data attribute，您需要更改：

$('#username').removeAttr("data-custom-class");
$('#username').attr("data-custom-class", "tooltip-success");

具有：

$('#username').data("customClass", "tooltip-success");

然后在第一个if部分中再次设置为危险。

摘要：

$('#username').tooltip();
$('#username').on('focusout', function() {
    if ($('#username').val() == "") {
        $('#username').tooltip('dispose');
        $('#username').attr("title","User must be at least 1 character long!");
        $('#username').data("customClass", "tooltip-danger");
        $('#username').tooltip('toggle');
        $('#username').focus();
    } else {
        $('#username').tooltip('dispose');
        $('#username').data("customClass", "tooltip-success");
        $('#username').attr("title","Username avaiable!");
        $('#username').tooltip('dispose');
        $('#username').tooltip('toggle');
    }
});
