我有简单的Html.BeginForm和一些数据,我想在用户点击时使用onsubmit()javascript函数检查一些条件"提交"按钮,表格将被发送。当这个条件为假时,我想停止重新加载页面,只是不要将我的表单发送到POST方法。这工作正常,我遇到了一个问题,因为我在onsubmit()方法中创建的 DOM元素消失了:
@using (Html.BeginForm("Register", "Account", FormMethod.Post, new { @class = "form-horizontal", role = "form", **onsubmit=" return registerValidation()"**}))
{
@Html.AntiForgeryToken()
@Html.TextBoxFor(m => m.Email, new { @class = "form-control", @id = "emailVal"})
@Html.ValidationMessageFor(m => m.Email,"", new { @class = "validation-error-white", @id="emailValidation"})
<input type="submit" class="btn btn-warning btn-block add-item-button-text" value="Zarejestruj" />
}
<script type="text/javascript">
function registerValidation() {
var validForm = validateRegisterForm(email, login);
if (!validForm) {
$('#emailValidation').append('Those email already exists! Take another one');
return false;
}
return true;
}
</script>
因此,当我想要返回false,并且不发送表单时,我附加到validation-div的文本会说明错误消失了 - 它不是我想要实现的,因为它&# 39;非常小的时间段,用户甚至都注意不到!

您手动触发按钮单击事件。确保 类型 是 按钮 。
您不需要**onsubmit=" return registerValidation()"**
<input id="btnSubmit" type="button" ... />
<script type="text/javascript">
$(function () {
// Trigger btnSubmit button's click event, when enter key is pressed.
// If you do not want that feature, you can ignore this.
$("form").keydown(function (event) {
if (event.keyCode === 13) {
$("#btnSubmit").click();
return false;
}
});
$("#btnSubmit").click(function () {
// Do something, then submit the form
$("form").submit();
});
});
</script>
