当用户提交表单时，我试图获取选定的复选框值及其旁边的隐藏字段值。
<form....>
<td><input type='checkbox' name='checkbox' value='1' ></input></td>
<input type='hidden' name='sid1' value='1'/>
<td><input type='checkbox' name='checkbox' value='1' ></input></td>
<input type='hidden' name='sid2' value='2'/>
<td><input type='checkbox' name='checkbox' value='1' ></input></td>
<input type='hidden' name='sid3' value='3'/>
我尝试:
$(document).ready(function(){
if( $("input[name='checkbox']['checked']")) {
$("input[name='checkbox']['checked']").each(function(){
var test=$(this).val();
alert(test);
})
}
})
但它会给我所有的复选框值，即使它们没有被选中。任何人都可以帮助我解决这个问题吗？非常感谢!

这里是:
<HTML>
<HEAD>
<TITLE>Multiple-Select Check Boxes</TITLE>
<SCRIPT LANGUAGE="JavaScript">
function getSelected(opt) {
var selected = new Array();
var index = 0;
for (var intLoop = 0; intLoop < opt.length; intLoop++) {
if ((opt[intLoop].selected) ||
(opt[intLoop].checked)) {
index = selected.length;
selected[index] = new Object;
selected[index].value = opt[intLoop].value;
selected[index].index = intLoop;
}
}
return selected;
}
function outputSelected(opt) {
var sel = getSelected(opt);
var strSel = "";
for (var item in sel)
strSel += sel[item].value + "\n";
alert("Selected Items:\n" + strSel);
}
</SCRIPT>
</HEAD>
<BODY>
