JavaScript检测多组Radio是否选择
function checkSubmit() {
var radioname;
var arrRadio = new Array();
var inputs=document.getElementById_x("form2").getElementsByTagName("input");
for(var i=0;i<inputs.length;i++) {
if(inputs[i].type=="radio"){
//这里将所有的radio根据name分组,便于之后按组判断是否选中(一组选中一个即可)
if (radioname !=inputs[i].name){
arrRadio.push(inputs[i].name);
radioname =inputs[i].name
}
}
}
for (var i=0;i<arrRadio.length;i++) {
var bRadio=false;
for (var j=0;j<document.getElementsByName(arrRadio[i]).length;j++) {
if (document.getElementsByName(arrRadio[i]).item(j).checked==true){
bRadio=true;
continue;
}
}
if (!bRadio){
alert("请仔细检查是否遗漏了调查选项！");
return false;
}
}
var params = "";
for (var i=0;i<arrRadio.length;i++) {
for (var j=0;j<document.getElementsByName(arrRadio[i]).length;j++) {
if (document.getElementsByName(arrRadio[i]).item(j).checked==true){

//params += arrRadio[i] +"|"+document.getElementsByName(arrRadio[i]).item(j).value;
params += document.getElementsByName(arrRadio[i]).item(j).value;
continue;
}
