js无法取得表单中的值。。
HTML code

------解决方案--------------------因为你迭代时候 得到的内容的有很多不只是一个
JScript code
var e = document.getElementsByTagName("input");
var hasNoneChecked = true;
for (var i = 0; i < e.length; i++) {
if (e[i].type == 'checkbox' && e[i].checked ) {
hasNoneChecked = false;
alert(e[i].value);
}
}
if (hasNoneChecked) {
return alert("请选择一个！");
}else{
//dosomething;
}
google搜索未果，string加上括号表示什么意思？该怎么解决
