date - 验证结束日期等于大于开始日期

Question

我想用 jquery validate 检查结束日期是否大于或等于开始日期。它正在验证大于开始日期的结束日期，但不允许结束日期等于开始日期，

这是我的代码-

    jQuery.validator.addMethod("greaterThan", 
function(value, element, params) {
    if (!/Invalid|NaN/.test(new Date(value))) {
        return new Date(value) > new Date($(params).val());
    }
    return isNaN(value) && isNaN($(params).val()) 
        || (Number(value) > Number($(params).val())); 
},'Must be greater than {0}.');

jQuery("#collect_and_delivery").validate({ 
        errorElement:'div',               
        rules: {                    
                from:{
                        required:true
                     },
                to:{
                    required:true
                },
                start_date:{
                    required:true
                },
                 end_date:{
                    required:true,
                    greaterThan: "#start_date"              
                }
        },
        messages: {
               from:"Please enter collect address",
               to:"Please enter delivery address",
               start_date:"Please enter shipping collect date",
               end_date:
               { 
                    required:"Please enter shipping delivery date",
                    greaterThan:"Delivery date and Collect date should be proper"
               }
        }                
    });

您应该在自定义方法 greaterThan 中使用 is greater than or equal to(>=)。

改变这一行:

return new Date(value) > new Date($(params).val());

收件人:

return new Date(value) >= new Date($(params).val());
