Bootstrap中的tooltip（“ show”）方法
使用Bootstrap中的tooltip（“show”）方法显示工具提示。如下所示，单击按钮即可看到工具提示：
$(document).ready(function(){
$(".btn-primary").click(function(){
$("[data-toggle='tooltip']").tooltip('show');
});
});工具提示将在链接中可见，其中我已设置了data-toggle属性和链接文本，如以下代码段所示-
<a href="#" data-toggle="tooltip" title="工具提示可见！"> On clicking the below button, the tooltip would be visible. </a>
您可以尝试运行以下代码以实现tooltip（“show”）方法-
