我有下一个表格:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
function submit(form) {
var first_pass = form.find('.first_try');
var second_pass = form.find('.second_try');
if (first_pass.value == second_pass.value) {
return true
}
first_pass.value = '';
second_pass.value = '';
first_pass.attr('placeholder', 'Пароли не совпадают');
first_pass.css('border-color', 'red');
second_pass.css('border-color', 'red');
return false
}
</script>
<form role="form" method="post" onsubmit="return submit($('#PasswordChange form'))">
<h3>Редактирование пользователя</h3>
<div class="form-group">
<input type="password" class="form-control first_try" name="password"
placeholder="Новый пароль"
required>
</div>
<div class="form-group">
<input type="password" class="form-control second_try" name="password"
placeholder="Повтор пароля"
required>
</div>
<input type="submit" name="submit" class="btn btn-primary pull-right" value="Отправить"></input>
</form>
&#13;
此脚本检查密码是否相同。
但是使用firefox调试器我无法发现它进入这种方法。
这是脚本的问题吗?或者是否有关于声明onsubmit处理程序的问题?
答案 0 :(得分:1)
存在很多问题:
value
更改为val
this
代替$('#PasswordChange form')
var first_pass = $('.first_try');
代替find
else
event.preventDefault();
停止刷新页面或提交页面。
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
function save(form) {
var first_pass = form.querySelector('.first_try');
var second_pass = form.querySelector('.second_try');
if (first_pass.value == second_pass.value) {
alert('its ok');
return true;
} else {
first_pass.value = '';
second_pass.value = '';
first_pass.placeholder = 'Пароли не совпадают';
first_pass.style.borderColor='red';
second_pass.style.borderColor='red';
return false
}
}
</script>
<form role="form" method="post" onsubmit="event.preventDefault(); return save(this)">

使用此功能:
onsubmit="return submit(this)"
答案 2 :(得分:0)
请更改提交功能名称,因为它是关键字,所以不使用它。同时删除提交按钮旁边的</input>
答案 3 :(得分:0)
使用此代码
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">
function submitData(form) {
var first_pass = form.find('.first_try');
var second_pass = form.find('.second_try');
if (first_pass.value == second_pass.value) {
return true
}
first_pass.value = '';
second_pass.value = '';
first_pass.attr('placeholder', 'Пароли не совпадают');
first_pass.css('border-color', 'red');
second_pass.css('border-color', 'red');
return false
}
</script>
</head>
<body>
<form role="form" method="post" onsubmit="return submitData($('#PasswordChange form'))">

如果您不需要取消提交操作,则不应返回任何内容。您还可以使用jQuery $("form").submit(function(e) {
var passwords = $('[name=password]');
if (passwords.eq(0).val() !== passwords.eq(1).val()) {
alert("Пароли не совпадают!");
return false;
}
});
方法的提交表单事件处理程序,而不是<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form role="form" method="post" action="/">
<h3>Редактирование пользователя</h3>
<div class="form-group">
<input type="password" class="form-control first_try" name="password" placeholder="Новый пароль" required >
</div>
<div class="form-group">
<input type="password" class="form-control second_try" name="password" placeholder="Повтор пароля" required />
</div>
<input type="submit" name="submit" class="btn btn-primary pull-right" value="Отправить" />
</form>
属性中的hanler定义。
h1.display-2 {
font-family: tahoma;
}
&#13;
{{1}}&#13;
另外,我建议您使用Bootstrap验证状态而不是输入的边框样式设置。
