Question

此代码有效，但我需要它基本上在id字段上执行If Else。如果id长度> 0，则不要根据需要检查名称，邮政编码。如果id不是> 0然后根据需要检查名称，邮政编码等。欢迎您的建议。谢谢，

 runAllForms();

您可以将必需值传递给下面给出的函数，假设id是输入字段的名称

var $id = $('input[name="id"]')
$("#artist_create_event").validate({

    // Rules for form validation
    rules: {
        artist_create_event_name: {
            required: true
        },
        artist_create_event_desc: {
            required: true
        },
        id: {
            required: true
        },
        name: {
            required: function () {
                return $id.val().length > 0;
            }
        },
        zipcode: {
            required: function () {
                return $id.val().length > 0;
            }

假设id是文本框的id。你可以这样做：

    name :  {
            required : $("#id").val().length <= 0
         },

    zipcode :  {
            required : $("#id").val().length <= 0
         },

使用If / Else语句的Jquery验证规则
