複選框計數

Question

我上fish1.html

<script type="text/javascript"> 
    function countCheckboxes () 
    { 
    var form = document.getElementById('testForm'); 
    var count = 0; 
    for(var n=0;n < form.length;n++) 
    { 
     if(form[n].name == 'items[]' && form[n].checked) 
     { 
     count++; 
     } 
    } 
    document.getElementById('checkCount').innerHTML = count; 
    } 
    window.onload = countCheckboxes; 
</script> 

具有3.

<frameset cols="16%,68%,16%"> 
    <frame src="fish.html" name="bodyleft" noresize scrolling=no> 
    <frame src="fish1.html" name="bodymid" noresize scrolling=no> 
    <frame src="fish2.html" name="bodyright" noresize scrolling=no> 
    </frameset> 

碼框架集內的框架10項內的複選框是否有可能進行計數選中的複選框的數量在fish2.html上，不在fish1上？我怎麼做？

Answer 1

嘗試這樣（沒有測試）：

var frame2 = document.getElementById('bodyright'); 
window.onload = countCheckboxes(frame2); 
function countCheckboxes (frame) 
{ 
    var forms = frame.document.getElementsByTagName('form'); 
    //... 
}
