我无法验证表单和模式。请帮我解决这个问题.. 提前致谢

你可以写一个简单的验证方法

一个例子可能是......

function checkValidation()
{
    var isValid = true;
    if($("#date").val() == null){
        isValid = false;
    }
    if($("#person").val() == null){
        isValid = false;
    }
    if($("#mail").val() == null){
        isValid = false;
    }
    return isValid;
}
if(checkValidation())
    $("#modalDialog").show();
else
    alert("Form is not valid");
