You can use logical operators(e.g. & & And | |) to do this. You can create a variable(such as allCatSelected) that stores whether the non-empty option is selected for both cat1 and cat2. If so, you can set the required attribute for cow1 and cow2 to false to disable their validation. You can also use this logic to validate all fields at form submission time. This code can be placed in the appropriate place in the form_check function as needed. A code example is as follows:

var allCatSelected = ($('#cat1').val() !== '') && ($('#cat2').val() !== '');

if (allCatSelected) {
    $('#cow1').prop('required', false);
    $('#cow2').prop('required', false);
} else {
    $('#cow1').prop('required', true);
    $('#cow2').prop('required', true);

value != '' && cat2.value != '') {//都不为空再执行验证,同时加上required property $('#cow1,#cow2').prop('required',true) valid1.cow1(); valid1.cow2(); } else {//移除required property $('#cow1,#cow2').prop('required', false) } return !v.has_errors(); }; .
