其实挺简单的,刚好今天有用到,顺手记一下,以后用就copy好了 .
<script language="javaScript">
//全选或全部不选
function checkall(){
var isChecked=(document.ck.checkAll.checked == true);
var elements=document.ck.elements;
var counter=elements.length;
for(i=0;i<counter;i++){
var element=elements[i];
if(element.type=="checkbox"){
element.checked=isChecked;
}
}
}
//是否有checkbox被选中
function anyChecked(){
var elements=document.ck.elements;
var counter=elements.length;
for(i=0;i<counter;i++){
var element=elements[i];
if(element.checked == true){
return true;
}
}
return false;
}
</script>
<form Method="post" action="a.asp" onsubmit="return anyChecked()">
全选:<input type="checkbox"onclick="checkall()" />
多项选择框列表:
<input type="checkbox" value="1"/>
<input type="checkbox" value="2"/>
<input type="checkbox" value="3"/>
<input type="submit" value="submit">
</form>
选中之后怎么取它们的值呢?别急,在ASP中取值真是太简单了。如下:
dim array_key
array_key= Split(Request.Form("cb"),",")
for each m in array_key
response.write m
next
