[解决办法]
本帖最后由 net_lover 于 2013-07-22 20:56:04 编辑 是因为变量重名了，采用了相同的变量名
你可以采用闭包的方法处理
window.onload = function () {
for (M = 2; M < 4; M++) {
document.getElementById("List" + M).M = M;
document.getElementById("List" + M).onclick = function (e) {
var obox = document.getElementById("List" + this.M);
var cboList = obox.getElementsByTagName("input");
var oText = document.getElementById("txt" + this.M);
var src = e ? e.target : event.srcElement;
if (src.tagName == "INPUT") {
var values = [];
for (var i = 0; i < cboList.length; i++) {
if (cboList[i].checked) {
values.push(cboList[i].nextSibling.innerHTML);
}
}
oText.value = values.join(",");
}
}
}
}
