复选框的问题，请大家指点，分不够再加

meizz(梅花雨) ：你这样不是只能传递一个mm的值gzh_seagull(不可) :我要的是当第二，第三....任何一个取消选中的时候，第一也取消选中

修改一下函数就可以了function mychk(obj,idx){
if (obj.name.indexOf("_")==-1) { //父checkbox
if (obj.checked){
for (var i=0;i<idx;i++){
var sObj = document.all(obj.name+"_"+i);
sObj.checked=true;
}
} else {
for (var i=0;i<idx;i++){
var sObj = document.all(obj.name+"_"+i);
sObj.checked=false;
}
}
} else { //子checkbox
var pObj = document.all(obj.name.split("_")[0]);
if (obj.checked) {
pObj.checked=true;
} else {
pObj.checked=false;
}
}
}

gzh_seagull(不可)：当第一没选中的时候，点击第二，第三.....，第一不变
只有第一选中以后，才出现我要的效果

ssm1226(雨中人);当第一没选中的时候，点击第二，第三.....，第一不变。
这样是不是只能得到一个mm的值呢麻烦你了

重新贴一个改过的<SCRIPT LANGUAGE="JavaScript">

</SCRIPT>
<INPUT TYPE="checkbox" NAME="chk0" onclick="mychk(this,3);"><BR>
    <INPUT TYPE="checkbox" NAME="chk0_0" onclick="mychk(this,3);"><BR>

meizz(梅花雨) ：你这样不是只能传递一个mm的值??你要在什么地方得到？在本页没有问题，若是放在表单里提交的话，只要是打勾的复选框都可以传值到后台页面，后台 request("mm") 得到是类似于这种形式的一个字串：a, b, c, d, e

gzh_seagull(不可)：当所有的都没有选的时候，点击第二或者第三或者....，第一都会选中，我要的是第一不便

meizz(梅花雨) ：我是放在表单里提交的，而且mm我是通过循环负的值，是mm[]这样的形式，而且不知道有几个，我用你的方法，只得到了一个的值

meizz(梅花雨) ：而且当所有分框都选中的时候，第一也选中，我不要这样的效果，麻烦你在帮我想想办法

to 楼主：同名checkbox，只要选中，获取值形式为：a,b,c.......未选中，获取不到

ssm1226(雨中人);当第一没选中的时候，点击第二，第三.....，第一不变。
这样是不是只能得到一个mm的值呢=================================================================
我的程序，是:如果全选，则选中，第一获取值的数目与第一的是否选中无关，而与第二，第三........选中的数目有关

gzh_seagull(不可) ：
for (var i=0;i<chklst.length;i++){
这样报错，‘缺少对象‘

gzh_seagull(不可) :我用php循环负的变量，‘第一‘的变量是_set_year[]不知道有几个，也不知道他有没有‘第二，第三....’，我通过php负给了一个script的变量，你帮我看一下，该如何做
<script>
var yearinfo;
yearinfo = new Array();
yearinfo[0] = new Array();
yearinfo[0]['year'] = 2010;
yearinfo[1] = new Array();
yearinfo[1]['year'] = 2009;
yearinfo[1]['term'] = new Array();
yearinfo[1]['term'][0] = 1;
yearinfo[1]['term'] = new Array();

yearinfo[7]['term'][2] = 3;
yearinfo[7]['term'] = new Array();
yearinfo[7]['term'][3] = 4;
</script>这是所有的数据，做出你的效果来就行了，帮帮忙了，谢谢了

错了，数据是这样的
<script>
var yearinfo;
yearinfo = new Array();
yearinfo[0] = new Array();
yearinfo[0]['year'] = 2010;
yearinfo[0]['term'] = '';
yearinfo[1] = new Array();
yearinfo[1]['year'] = 2009;
yearinfo[1]['term'] = new Array();
yearinfo[1]['term'][0] = 1;
yearinfo[1]['term'][1] = 2;
yearinfo[2] = new Array();
yearinfo[2]['year'] = 2008;
yearinfo[2]['term'] = new Array();
yearinfo[2]['term'][0] = 1;
yearinfo[3] = new Array();
yearinfo[3]['year'] = 2007;
yearinfo[3]['term'] = '';
yearinfo[4] = new Array();
yearinfo[4]['year'] = 2005;
yearinfo[4]['term'] = '';
yearinfo[5] = new Array();
yearinfo[5]['year'] = 2004;
yearinfo[5]['term'] = '';
yearinfo[6] = new Array();
yearinfo[6]['year'] = 2003;
yearinfo[6]['term'] = new Array();
yearinfo[6]['term'][0] = 1;
yearinfo[7]['term'] = new Array();
yearinfo[7]['term'][0] = 1;
yearinfo[7]['term'][1] = 2;
yearinfo[7]['term'][2] = 3;
yearinfo[7]['term'][3] = 4;
</script>

这些数据是什么回事,用不了!!
alert(yearinfo)看看是什么!!!

为什么要输出数组呢?直接输出checkbox的列表不就可以了.
把你用php生成数组的代码贴出来,我帮你改改.

这是我的代码：$year      = date('Y-m-d', $_HY_ENV['time']);

$td    = "[未启用]";
$input = "<input type='checkbox' name='_del_year_' value='{$year_info[$year1[$i]]['data']['year_id']}'>";

js中的数组有别的用处吗?实现你问题的功能不需要js数组

把下面的函数加到你的js中function mychk(obj,isParent){
if (isParent){ //父checkbox
var chklst = obj.parentElement.parentElement.nextSibling.all("_del_term_")
if (obj.checked){
for (var i=0;i<chklst.length;i++){
chklst[i].checked=true;
}
} else {
for (var i=0;i<chklst.length;i++){
chklst[i].checked=false;
}
}
} else { //子checkbox
var tr = obj.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement;
var pObj = tr.parentElement.rows[tr.rowIndex-1].all("_del_year_");
if (!obj.checked) {
pObj.checked=false;
}
}
}

"parentElement.parentElement.nextSibling"不是对象我要把
function mychk(obj,isParent){
if (isParent){ //父checkbox
var chklst = obj.parentElement.parentElement.nextSibling.all("_del_term_")
if (obj.checked){
for (var i=0;i<chklst.length;i++){
chklst[i].checked=true;
}
} else {
for (var i=0;i<chklst.length;i++){
chklst[i].checked=false;
}
}
} else { //子checkbox
var tr = obj.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement;
var pObj = tr.parentElement.rows[tr.rowIndex-1].all("_del_year_");
if (!obj.checked) {
pObj.checked=false;
}
}
}
加到$script .= "</script>";里面

我把测试的代码贴出来,看看html代码和你的有什么不同

以后不要老是让别人帮你改代码,给你一个思路你应该自己试试,这样才能学到东西.

主要是我对js还只是一知半解，谢谢你的帮助，但是还是不对啊
第一个错误"parentElement.parentElement.nextSibling不是对象"；
第二个错误"parentElement.rows[...]不是对象";

最后一行需要改一下$script .= "function mychk(obj,isParent){if (isParent){var chklst = obj.parentElement.parentElement.nextSibling.all('_del_term_')if (chklst != null) {if (chklst.length != null) {for (var i=0;i<chklst.length;i++){chklst[i].checked=obj.checked;}} else chklst.checked=obj.checked;}}} else {var tr = obj.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement;var pObj = tr.parentElement.rows[tr.rowIndex-1].all('_del_year_'); if (!obj.checked) { pObj.checked=false;}}}</script>";

你能自己解决最好了,你的class效果要出来可能需要修改我的函数,给你提示
parentEelment是当前元素的父元素
nextSibling是当前原是的下一个原是
只要理清了就可以
