我正在处理一个联系人搜索页面，遇到了一个问题。我的控制台没有错误，但当我运行搜索时，不会生成结果，并且会提示所有输入验证错误。
例如：
Jane Grey
Jane Grey 的搜索
这是我的VisualForce页面：
<apex:page id="ContactPage" controller="Ctrl_ContactSearch">
<apex:tabPanel id="ContactPanel">
<apex:tab id="ContactTab" label="Contact Search">
<apex:form id="ContactForm">
<!-- Input Fields -->

<apex:inputText id="NameInputField" value="{!name}" />
</apex:pageBlockSectionItem>
<apex:pageBlockSectionItem id="PhoneInputBlock">
<apex:outputLabel value="Phone" />
<apex:inputText id="PhoneInputField" value="{!phone}" />
</apex:pageBlockSectionItem>
<apex:pageBlockSectionItem id="EmailInputBlock">
<apex:outputLabel value="Email" />
<apex:inputText id="EmailInputField" value="{!email}" />
</apex:pageBlockSectionItem>
</apex:pageBlockSection>
<!-- Buttons -->

}我哪里错了？
出于某种原因，StackOverflow不允许我在不添加额外文本的情况下发表这篇文章。我把这个放在这里是为了增加字数。
第一，一些建设性的批评：
DRY原则说你应该把你的验证方法组合成1。
第二，看起来您的正则表达式不太好。根据验证的确切要求，您可以尝试以下操作。。。随意取自论坛上对其他问题的其他回复，就像这个。。。(我绝非Regex专家(
试试这样的东西：
private string nameRegEx = '^[a-zA-Z][a-zA-Z0-9 ]+$';
private string emailRegEx = '^[a-zA-Z0-9._|\\%#~`=?&/$^*!}{+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$';
private string phoneRegEx = '^(\d{3}\-\d{3}-\d{4})?$';
public static Boolean Validate (String str, String validation)
{
Boolean IsValid = false;
Pattern Pattern = Pattern.compile(validation);
Matcher Matcher = Pattern.matcher(str);
if (Matcher.matches())
{
IsValid = true;
}
return IsValid;
}
此外，此函数还返回一个Boolean。在检查其返回值时，不需要相等运算符。只需使用if (Validate(name, nameRegex)) { ... }或if (!Validate(email, emailRegex)) { ... }
