动态创建radio、checkbox时需要注意的问题

1、给radio、checkbox后面添加文字

2、创建默认选中

3、创建完可选

function create(){
        var board = document.getElementById("layer1_content1");
        var e = createElement("input","cpname");
        e.type = "checkbox";
        e.id = "chid";
        e.value ="123";
        board.appendChild(e);
        //设置选中
        e.setAttribute("checked","checked");
        //添加文字
        board.appendChild(document.createTextNode("测试"));
   }

   function createElement(type, name) {
       var element = null;
       try {
          // First try the IE way; if this fails then use the standard way
          element = document.createElement('<'+type+' name="'+name+'">');
       } catch (e) {
          // Probably failed because we’re not running on IE
       }
       if (!element) {
          element = document.createElement(type);
          element.name = name;
       }
       return element;
    }

function create(){
   		var board = document.getElementById("layer1_content1");
		var e = createElement("input","cpname");
		e.type = "checkbox";
		e.id = "chid";
		e.value ="123"; 
		board.appendChild(e);
		//设置选中
		e.setAttribute("checked","checked");
		//添加文字
		board.appendChild(document.createTextNode("测试"));
   }
   
   function createElement(type, name) {   
	   var element = null;   
	   try {   
		  // First try the IE way; if this fails then use the standard way   
		  element = document.createElement('<'+type+' name="'+name+'">');   
	   } catch (e) {   
		  // Probably failed because we’re not running on IE   
	   }   
	   if (!element) {   
		  element = document.createElement(type);   
		  element.name = name;   
	   }   
	   return element;   
	}

注意：1、由于IE的问题，必须使用以上createElement（）方法创建name属性，否则在IE中无法选中，其他浏览器不需要这样。

         2、在IE浏览中，通过document.createElement("input")来生成的radio和checkbox都无法通过document.getElementsByName()方法来获取
