mui开发中获取单选按钮、复选框的值(实例讲解)
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。
以上这篇mui开发中获取单选按钮、复选框的值(实例讲解)就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持软件开发网。
