要说明问题:当我提交表格时,我的功能并没有告诉我任何事情。网址会发生变化,但似乎功能未被触发。请帮忙!
<div id="contact_form">
<form name="contact" action="">
<fieldset>
<label for="name" id="name_label">Name</label>
<input type="text" name="name" id="name" size="30" value="" class="text-input" />
<label class="error" for="name" id="name_error">This field is required.</label>
<label for="email" id="email_label">Return Email</label>
<input type="text" name="email" id="email" size="30" value="" class="text-input" />
<label class="error" for="email" id="email_error">This field is required.</label>
<label for="phone" id="phone_label">Return Phone</label>
<input type="text" name="phone" id="phone" size="30" value="" class="text-input" />
<label class="error" for="phone" id="phone_error">This field is required.</label>
<br />
<input type="submit" name="submit" class="button" id="submit_btn" value="Send" />
</fieldset>
</form>
</div>
<script>
$(function() {
$('.error').hide();
$(".button").click(function() {
// validate and process form here
$('.error').hide();
var name = $("input#name").val();
if (name == "") {
$("label#name_error").show();
$("input#name").focus();
return false;
}
var email = $("input#email").val();
if (email == "") {
$("label#email_error").show();
$("input#email").focus();
return false;
}
var phone = $("input#phone").val();
if (phone == "") {
$("label#phone_error").show();
$("input#phone").focus();
return false;
}
});
});
</script>
提前致谢!
PS:已经在Google上搜索过了,但没有找到好结果。

首先,将事件参数添加到按钮单击处理程序,如下所示:
$(".button").click(function(e)){
然后也改变
return false;
要
e.preventDefault();
编辑:
此代码适用于我。当您单击字段为空的按钮时,表单未提交,并显示第一个字段旁边的错误文本。顺便说一句,这里没有涉及到PHP,只有html和jquery。你在页面中加载jquery吗?

使用它:
$('form[name="contact"]').on('submit', function() {
$('.error').hide();
var name = $("input#name").val();
if (name.length == 0) {
$("label#name_error").show();
$("input#name").focus();
return false;
}
var email = $("input#email").val();
if (email.length == 0) {
$("label#email_error").show();
$("input#email").focus();
return false;
}
var phone = $("input#phone").val();
if (phone.length == 0) {
$("label#phone_error").show();
$("input#phone").focus();
return false;
}
return true;
});
