问题描述
我有一个简单的教育详细信息页面,我在其中动态生成文本框以输入资格详细信息.当我尝试验证文本框时,将触发验证,但验证不正确.如果我尝试2-3次,它将变得正确.在第一次尝试中,备用文本框将得到验证.当我单击添加行"按钮时,将添加新行,但是当我尝试对其进行2-3次验证时,不会显示验证错误.再进行几次尝试后,验证便会生效.这一切都很混乱.
I have a simple educational details page where I am generating textboxes dynamically to enter qualification details. When I try to validate the textboxes, the validation gets fired but not properly. If I try it 2-3 times then it becomes proper. In the first attempt alternate textboxes get validated. When I click on "add row" button a new row gets added but when I try to validate it for 2-3 attempts the validation error is not shown. After few more attempts the validation works. It is all very confusing.
我在互联网上进行了很多研究,但找不到任何合适的解决方案.
I researched a lot on the internet but could not find any proper solution.
我在下面粘贴了完整的JSP.真的非常感谢任何指针.
I have pasted my full JSP below. Will be really really thankful for any pointers.

推荐答案
由于您正在动态创建这些元素,因此请尝试授权您的活动:
Since you're creating those elements dynamically, try delegating your events:
jQuery(document).on("blur",".validate-text", function (event) {
// repeat for ".validate-num"
此外,您不应该使用两种不同版本的jQuery.删除<script src="../js/jquery-1.3.2.js" type="text/javascript"></script>
Additionally, you shouldn't be using two different versions of jQuery. Remove <script src="../js/jquery-1.3.2.js" type="text/javascript"></script>
