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。
