如何用JS删除checkbox选中的记录

/** 选取选中的复选框的值 */
function checkbox_selected() {
var chkvalue = "";
var chk = window.document.getElementsByName("chkUserInfos");
for (var i = 0; i < chk.length; i++) {
if (chk[i].checked) {
chkvalue = chkvalue + "," + chk[i].value + "";
}
}
return chkvalue;
}

/* 复选框全部选中或相反 */
function checkbox_selectedAll() {
var chk = window.document.getElementsByName("chkUserInfos");
for (var i = 0; i < chk.length; i++) {
chk[i].checked = window.document.getElementById("chkFile").checked;
}
}

function selectDelete() {

var documentStrIds="";
var chkUserInfos=document.getElementsByName("chkUserInfos");
for(var i=0;i<chkUserInfos.length;i++){
if(documentIds[i].checked){
documentStrIds+=chkUserInfos[i].value+";";
flag=true; // 表示复选框有被选中的
}
}
if(flag){
window.location.href="......?documentStrIds="+documentStrIds; // 提交后台
// 别忘了传参
}
}

后台 读取documentStrIds

if(documentStrIds!=null && !"".equals(documentStrIds.trim())){
String[] ids=documentStrIds.split(";");
if(ids.length>0){
boolean flag=false;
for(String idStr : ids){
// 循环删除
}
}
}

<a href="javascript:window.Insert()">新增</a> <a href="javascript:window.selectAll()"> 全选</a> <a href="javascript:window.selectNotAll()">反选</a> <a href="javascript:window.selectDelete()">删除</a>
