项目问题如下图,
点击确定后,模态框没反应,按理,点击删除按钮时,弹出确认删除的模态框,点击确定后,使用ajax请求服务器,把数据库中对应的数据进行删除,根据服务器 servlet返回的状态值(delTag的值),来确定是否删除成功,delTag为true,删除成功,此时应执行语句 $(\'#deleteMessModal\').modal(\'hide\'); 把模态框关掉,但是调试时怎么页关闭不掉,F12进入调试模式,转到console里面一看,报错了: Uncaught TypeError: $(...).modal is not a function, 看到网上有人说可能时jquer.js 和 bootstrap.js引入的顺序有关,到head标签中一看,果然,bootstrap.js 确实在jquery.js的前面引入的,于是调换位置再试,结果没有再报错了,回到页面调试,弹出的模态框也能正常关掉了!
