mui开发中获取单选按钮、复选框的值

js获取单选按钮的值

function getVals(){
    var res = getRadioRes('rds');
    if(res == null){mui.toast('请选择'); return;}
    mui.toast(res);
}
function getRadioRes(className){
    var rdsObj = document.getElementsByClassName(className);
    var checkVal = null;
    for(i = 0; i < rdsObj.length; i++){
        if(rdsObj[i].checked){checkVal = rdsObj[i].value;}
    }
    return checkVal;
}

js获取复选框的值

function getVals(){
    var res = getCheckBoxRes('rds');
    if(res.length < 1){
        mui.toast('请选择');
        return;
    }
    mui.toast(res);
}
function getCheckBoxRes(className){
    var rdsObj   = document.getElementsByClassName(className);
    var checkVal = new Array();
    var k        = 0;
    for(i = 0; i < rdsObj.length; i++){
        if(rdsObj[i].checked){
            checkVal[k] = rdsObj[i].value;
            k++;
        }
    }
    return checkVal;
}

 单选按钮、复选框先分别设置相同的类名，再通过获取类名的方式获取到，再做后续的处理。
