我想使用jquery插件仅在名称部分使用字母来验证我的表单。这样，当用户输入特殊字符或数字时会出现错误。我还想在用户输入信息（即在提交表单之前进行实时验证）时检查表单验证。

var RegEx = /^[a-zA-Z\s]*$/;
if (RegEx.test($('#input').val())) {
}
else {
$('#input').val("");
}
});````
You have to wrap all the input elements in <form></form> and use jquery Validate plugin. Refer this link: http://jqueryvalidation.org/validate/ for detailed explanation
