<script language="javascript"> 
function checkall(form){
	//alert(form.selectall.value);
	for (var i=0;i<form.elements.length;i++){
		//为了使用方便将form.elements[i]赋值繪变量e
		var e=form.elements[i];
		//判断对象类型是否为复选框
		if (e.type=="checkbox"){
			e.checked=true;
		}
		// 全选则使"选中归还或续借的文献radio"不选上
		if (e.name=="selecttype"){
			e.checked=false;
		}
	}
}
function returnbook(form)
