怎么在弹出window动态生成div

点击事件preview

function preview(){

                    

		var win=window.open('','','width=200,height=200');

			for(i=1;i<7;i++){

				var "txt_"+i+"" = "<div><table><tr><td>"+i+"</td></tr></table></div>";

				

		  		win.document.write("txt_"+i+"");

  				alert("txt_"+i+"");

			}

		  //var txt_1 = "<div><table><tr><td>123</td></tr></table></div>";

		  //var txt_2 = "<div><table><tr><td>2</td></tr></table></div>";

		  win.document.open("text/html","replace");

		  //win.document.write(txt_1);

                    //win.document.write(txt_2);

		  win.document.close();

		  

	}

实现的功能是点击button 执行preview方法,弹出一个window,里面做div层的循环
问题是用了for点击事件失效,没有for新开的window可以显示结果:

123
2
