jQuery筛选两个参数

Question

This code validates a set of form elements,

var objects = $(".validated").filter(function (){
    return $(this).val() == '';
});

Is there i could also filter for a length of >10, for example?

Thanks!

Answer 1

Either chain together another filter, or modify the condition.

var objects = $(".validated").filter(function (){
    return $(this).val() == '' || $(this).val().length > 10;
});

Alternatively

var objects = $(".validated").filter(function (){
    return $(this).val() == '';
}).filter(function(){
    return $(this).val().length > 10;
});
