window.open打开新窗体并用post方式传参

function openPostWindow(url,data,name){  //url要跳转到的页面，data要传递的数据，name新窗体名
          var tempForm = document.createElement("form");  
          tempForm.id="tempForm1";  
          tempForm.method="post";  
          tempForm.action=url;  
          tempForm.target=name;  
          var hideInput = document.createElement("input");  
          hideInput.type="hidden";  
          hideInput.name= "dataname"
          hideInput.value= data;
          tempForm.appendChild(hideInput);   
          tempForm.attachEvent("onsubmit",function(){ openWindow(name); });//必须用name不能用url，否则无法传值到新页面
          document.body.appendChild(tempForm);           
          tempForm.fireEvent("onsubmit");
          tempForm.submit();
          document.body.removeChild(tempForm);
}


function openWindow(name)  {  
     var iWidth=1100; //弹出窗口的宽度;
     var iHeight=550; //弹出窗口的高度;
     var iTop = (window.screen.availHeight-30-iHeight)/2; //获得窗口的垂直位置;
     var iLeft = (window.screen.availWidth-10-iWidth)/2; //获得窗口的水平位置;
