如下代码：怎么实现点击不同的radio单选改变file_upload_limit，也就是当值是不是0时file_upload_limit 是10，当值是0时file_upload_limit 是1


<script type="text/javascript">
var swfu;
window.onload = function() {
var settings = {
flash_url : "swfupload/swfupload.swf",
upload_url: "swfupload.php",
post_params: {"PHPSESSID" : "<?php echo session_id(); ?>"},
file_size_limit : "3 MB",
file_types : "*.jpg;*.jpeg;*.jpe",
file_types_description : "jpg图片",
file_upload_limit : 1,
file_queue_limit : 0,
custom_settings : {
progressTarget : "fsUploadProgress",
cancelButtonId : "btnCancel"
},
debug: false,
// Button settings
button_image_url: "swfupload/TestImageNoText_65x29.png",
button_width: "65",
button_height: "29",
button_placeholder_id: "spanButtonPlaceHolder",
button_text: '<span class="theFont">选择</span>',
button_text_style: ".theFont { font-size: 16; }",
button_text_left_padding: 12,
button_text_top_padding: 3,

// The event handler functions are defined in handlers.js
file_queued_handler : fileQueued,
file_queue_error_handler : fileQueueError,
file_dialog_complete_handler : fileDialogComplete,
upload_start_handler : uploadStart,
upload_progress_handler : uploadProgress,
upload_error_handler : uploadError,
upload_success_handler : uploadSuccess,
upload_complete_handler : uploadComplete,
queue_complete_handler : queueComplete // Queue plugin event
};


swfu = new SWFUpload(settings);
};
</script>

var objIsMore=document.all("radVote");
for(var i=0;i<objIsMore.length;i++){
if(objIsMore[i].checked==true)
{
file_upload_limit=1;
}else{
file_upload_limit=0;
}
}

function fuzhi(value){
var radiovalue = document.getElementsById("checkRadio");
var limtValue = document.getElementsById("file_upload_limit");
if(limtValue == 0 && radiovalue == 0){
limtValue.value = 1;
}else{
limtValue.value = 0;
}
}
<input type="radio" id="checkRadio" onclick="fuzhi(0)">
<input type="radio" id="checkRadio" onclick="fuzhi(1)">
