按钮版
//全选 
		 function swapCheck() {  
            var cs=document.getElementsByName("che");
		    for(var i=0;i<cs.length;i++){
		    	cs[i].checked=true;
		    		    	
		    }		    	     
		 } 
		 //取消全选
		 function swapCheck1() {  	   
			    var cs=document.getElementsByName("che");
			    for(var i=0;i<cs.length;i++){
			    	cs[i].checked=false;   	
			    }
			 } 
checkedbox版（功能更全面）


	function swapCheck2()	
		{
			var cks = document.getElementsByName('che');
			var xxx = document.getElementsByName('xxx');
			var a = 0;
			for ( var i = 0; i < cks.length; i++)    {						
				if(cks[i].checked == false){
					a = 1;
					ks[i].checked = true;   
					}
				}
				if(a == 0){
				for( var j = 0 ; j < cks.length; j++){
					cks[j].checked = false;
					xxx[0].checked = false;
				}
			}
	}
