Question

How do you create a simple, custom rule using the jQuery Validate plugin (using addMethod ) that doesn't use a regex?(如何使用不使用正则表达式的jQuery Validate插件（使用addMethod ）创建简单的自定义规则？)

For example, what function would create a rule that validates only if at least one of a group of checkboxes is checked?(例如，什么功能会创建仅在选中一组复选框中的至少一个时才验证的规则？)   ask by Edward translate from so

You can create a simple rule by doing something like this:(您可以通过执行以下操作来创建一条简单的规则：)

jQuery.validator.addMethod("greaterThanZero", function(value, element) { return this.optional(element) || (parseFloat(value) > 0); }, "* Amount must be greater than zero"); And then applying this like so:(然后像这样应用：) $('validatorElement').validate({ rules : { amount : { greaterThanZero : true } } }); Just change the contents of the 'addMethod' to validate your checkboxes.(只需更改“ addMethod”的内容即可验证您的复选框。)
