Question

我遇到了这个问题，我觉得这很容易，问题是要验证动态创建的文本框值，从第一个文本框我已经从值01:00写入，到值为03:00，在第二个textbox我写的价值为＆＃39; 02：00＆＃39;到＆＃39; 00＆＃39;所以我想验证这个，当我点击它应该限制它的验证按钮，因为这个值（＆＃34; 02：00＆＃34; - ＆＃34; 04：00＆＃34;）介于两者之间（＆＃34; 01：00-03：00＆＃34;），所以它应该验证并在其他新创建的动态文本框中进行验证

------------------------------------------------------------
|from 01:00                    to 03:00 

|from 02:00                    to 04:00  **restriction**

|from 03:00                    to  05:00 right value(validated)

这是我创建动态复选框和检查的代码 jQuery添加/删除文本框示例

您应该尝试此代码

                div{
                    padding:8px;
                }
            </style>

        </head>
