我不熟悉百里香。我想将百里香叶和JQuery集成到Clint边验证中。这是代码。请看一下这段代码。错误在哪里以及如何解决这个问题。我的JQuery文件无法读取位置信息。

$(document).ready(function() {
alert("Hi");
$("#firstname").blur(function() {
var un=$("#firstname").val();
if($(this).val() == ''){

$('#firstname').focus();

$("#p").text("");

客户端验证不是一个好主意。可以在浏览器中禁用JavaScript,并且验证无效。了解有关field errors的信息。提交表单后,控制器方法可以检查表单是否为@Valid
,并且在BindingResult
中存在所有错误。你可以做类似的事情:
@RequestMapping(value="/my", method = "POST")
public String postForm(final @Valid MyForm form, final BindingResult bindingResult, final ModelMap model) {
if (bindingResult.hasErrors()) {
return "my";
}
model.clear();
return "redirect:/success";
}
我有一些建议可以帮助解决为什么未调用JQuery代码的问题。
将<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
放在closing body tag
之前和/或可能需要使用jQuery库的任何基于jquery的库之前的最后一行。这已成为html代码加载完成后最后应该加载的jQuery。
检查此部分。在我看来,这似乎是不必要的重复,仅使用下面的代码行:
var un=$("#sex").val(); //this line is the same as $(this).val()
if($(this).val() == ''){ ....
希望这对寻求类似解决方案的人有所帮助
