Posted 2020-08-09

js：

var obj = document.getElementsByName("yk");
    var check_val = [];
    for(k in obj){
        if(obj[k].checked)
            check_val.push(obj[k].value);
    }

jquery：

$(document).ready(function(){
    var checked = [];
    $("#submitButton").click(function(){
        $(‘input:checkbox:checked‘).each(function() {
            checked.push($(this).val());
        });
        alert(checked);
    });
});

 

 

 

 

 

$(document).ready(function(){

    var checked = [];

    $("#submitButton").click(function(){

        $(‘input:checkbox:checked‘).each(function() {

            checked.push($(this).val());

        });

        alert(checked);

    });

});
