复制代码代码如下:
<script>
وظيفة func () {
VAR OPTIONS = document.getElementSbyName ("chkbox") ؛
لـ (var i = 0 ؛ i <options.length ؛ i ++) {
if (! خيارات [i] .disabled) {
الخيارات [i] .cked = true ؛
}
}
}
</script>

<type type = checkbox name = chkbox value = 1>
<type type = checkbox name = chkbox value = 1>
<type type = checkbox name = chkbox value = 1>
<type type = button value = "测 试" onClick = "func ()">
用 JavaScript 吧。
复制代码代码如下:
<html>
<body>
<script>
وظيفة kk () {
var galleel = document.getElementById ("kkhandler") ؛
var els = document.getElementSbyName ("kk") ؛
لـ (i = 0 ؛ i <els.length ؛ i ++) {
els [i]
}
}
</script>
<type type = checkbox onClick = "kk ()" name = "kkhandler"> 全选 <br>
<type type = checkbox name = "kk">
<type type = checkbox name = "kk">
</body>
</html>
