本文实例为大家分享了js实现全选和全不选的具体代码，供大家参考，具体内容如下
非常简洁的几行原生js实现全选和全不选，大神们可以在此基础上加上反选功能。
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>全选、全不选</title>
</head>
<body>
<table border="1">
<tr>
<td><input type="checkbox" name="mmAll" onclick="Allthis, 'mm[]')"></td>
</tr>
<tr><td><input type="checkbox" value="1" name="mm[]" class="check" id="ids1" onclick="Itemthis, 'mmAll')"></td></tr>
<tr><td><input type="checkbox" value="2" name="mm[]" class="check" id="ids2" onclick="Itemthis, 'mmAll')"></td></tr>
<tr><td><input type="checkbox" value="3" name="mm[]" class="check" id="ids3" onclick="Itemthis, 'mmAll')"></td></tr>
<tr><td><input type="checkbox" value="4" name="mm[]" class="check" id="ids4" onclick="Itemthis, 'mmAll')"></td></tr>
<tr><td><input type="checkbox" value="5" name="mm[]" class="check" id="ids5" onclick="Itemthis, 'mmAll')"></td></tr>
<tr><td><input type="checkbox" value="6" name="mm[]" class="check" id="ids6" onclick="Itemthis, 'mmAll')"></td></tr>
</table>
</body>
</html>
<script type="text/javascript">
//Check all
function Alle, itemName)
{
var aa = document.getElementsByNameitemName);
for var i=0; i < aa.length; i++)
aa[i].checked = e.checked; //得到那个总控的复选框的选中状态
}
//Single select
function Iteme, allName)
{
var all = document.getElementsByNameallName)[0];
if!e.checked) all.checked = false;
else
{
var aa =document.getElementsByNamee.name);
for var i=0; i<aa.length; i++)
if!aa[i].checked) return;
all.checked= true;
}
}
</script>
