Question

我的javascript和asp.net mvc打印预览有问题。我获取搜索数据并通过JSON将数据传递给JavaScript函数：

function preview (content) ( 
             debugger; 
             var result = content.get_response (). get_object (); 
             var json = eval (result); 
             var w = window.open ( 'Stampa.aspx', "Research Press", "height = 1200, width = 1000, status = yes, toolbar = no, menubar = no, location = no"); 
            w.document.open (); 

             HeadPrint + = "<table border=1>"; 
             CreateTableRicercaHead (); 
             CreateTableRicercaMain (JSON) 
             FootPrint + = "</ table>"; 

             var node = w.document.createTextNode (HeadPrint + + strPrint Footprint); 
             alert (node.data); 
             var divPrint = w.document.getElementById (PrintDocument); 
             / / divPrint.innerHTML = HeadPrint + + strPrint footprint; 
             divPrint.appendChild (node); 
             alert (divPrint.appendChild (node)); 

  CreateTableRicercaMain function (data) ( 
             for (var list in data.r) ( 
                 strPrint + = "<tr>";

                 strPrint + = "<td>";

                 strPrint + = "<td>"; 
                 strPrint + = data.r [list]. common;

             )

以及如何你可以看到我尝试用innerHTML方法在div中写入结果，因为如果你用document.write（）写它，我注意到对于一定大小（4000）的数据，显示是1分钟。，但问题是当我打开弹出窗口时，我不显示任何白色，如果我右键单击 - >查看HTML我没有看到任何内容。您能帮我解决这个问题吗？

Answer 1

不确定为什么不在服务器端构建最适合循环的表。 JavaScript在大型循环中非常糟糕。

我的代码中没有看到w.document.close（）。

Answer 2

您好，感谢您的回答，同时服务器端也有一定数量的数据，页面显示速度非常慢。我的目标是通过json传递数据，将div.innerHTML设置为结果，因为如果我放在同一页面上，我会在不到1秒的时间内显示4000条记录。然后我想打开文档，然后读取我创建页面的div，但不起作用。

然后你建议我做服务器端的一切？感谢

使用javascript打印预览不起作用
