如何在不同的窗口中打开.aspx页面 [英] how to open .aspx page in different window

问题描述

我想知道如何在不同的窗口中打开网页，并在页面加载时将值从javascript传递到c＃

 <   JavaScript   >  
函数open_win（）
 {
 var s = document.getElementById（txtQty）; 
 window.open（../ Stock / IPurchaseDetail.aspx，_ blank，toolbar = yes，location = yes，directories = no，status = no，menubar = yes，scrollbars = yes，resizable =不，copyhistory = yes，width = 400，height = 400）; 
} 
 
 <   / java   script  >  
 
 
 <   asp：CheckBox     runat   =  server    ID   =  chkGenerateSerialNumber    AutoPostBack   =  true     CausesValidation   = < span class =code-keyword> false  
   
                   OnCheckedChanged   =  chkGenerateSerialNumber_CheckedChanged    /  >  

  protected   void  chkGenerateSerialNumber_CheckedChanged（ object  sender，EventArgs e）
 {
 
  if （chkGenerateSerialNumber.Checked ==  true ）
 {
 Session [  NoOfRows] = txtQty.Value; 
 
 
 System.Text.StringBuilder sb =  new  System.Text.StringBuilder（）; 
 sb.Append（ @ < script language ='javascript'>） ; 
 sb.Append（ @  open_win（）;）; 
 sb.Append（ @ < / script>）; 
 ScriptManager.RegisterStartupScript（ this ， this  .GetType（），  javascript，sb.ToString（）， true ）; < span class =code-comment> //  它确实有效但在open_win（）方法window.open（../ Stock / IPurchaseDetail.aspx， _blank，toolbar = yes，location = yes，directories = no，status = no，menubar = yes，scrollbars = yes，resizable = no，copyhistory = yes，width = 400，height = 400）;没有接到电话 
} 
} 

现在我有Session [NoOfRows] = txtQty.Value;但是另一个页面没有调用。

  protected   void  Page_Load（ object  sender，EventArgs e）
 {
  if （ ！IsPostBack）
 {
 NoOfRows Convert.ToInt32（（ string ）HttpContext.Current.Session [   NoOfRows]）; 
 
} 
 
} 
 

解决方案

你好，



至少有两种方法可以做到这一点。

1. 类似于你的除了将所需参数作为查询字符串传递之外的代码。你的代码变成如下所示的代码。
   
   

     function  open_win（）{
    < span class =code-keyword> var  s =  document  .getElementById（ < span class =code-string> txtQty）; 
     var  url =   ../ stock /IPurchaseDetail.aspx?txtQty = + encodeURIComponent（s.value）; 
     window  .open（url，  _ blank ，  toolbar = yes，location = yes，directories = no，status = no，menubar = yes ，scrollbars = yes，resizable = no，copyhistory = yes，width = 400，height = 400）; 
   } 

2. 此方法与上述非常相似，唯一的区别是您使用空白网址打开命名窗口并将现有表单POST到该窗口。以下代码段显示了如何完成此操作。
   
   

     function  open_win（）{
    < span class =code-keyword> var  hWin =  window  .open（ < span class =code-string>，  hWinPurchase，  toolbar = yes，location = yes，directories = no，status = no，menubar = yes，scrollbars = yes，resizable = no， copyhistory = yes，width = 400，height = 400）; 
     var  frm =  document  .getElementById（'   YOUR_FORM_NAME'）; 
    frm.target =   hWinPurchase; 
    frm.submit（）; 
   } 

问候，

添加目标属性以形成标签，完成后。

现在每当点击按钮时，aspx将在新窗口中打开。

将以下代码粘贴到 .ASPX页面

< pre lang =HTML> < 表格 id = form1 < span class =code-attribute> runat = server target = _ blank >

<！ - 在此处添加按钮 - >

< / form >

转到工具 - >选项 - >内容并取消选中阻止弹出窗口。

I want to know that how to open web page in different window and passed a value from javascript to c# on page load

<JavaScript>
function open_win() 
{
var s=document.getElementById("txtQty");
window.open("../Stock/IPurchaseDetail.aspx","_blank","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400");
}

</javascript>


<asp:CheckBox runat="server" ID="chkGenerateSerialNumber" AutoPostBack="true" CausesValidation="false"

        OnCheckedChanged="chkGenerateSerialNumber_CheckedChanged" />

protected void chkGenerateSerialNumber_CheckedChanged(object sender, EventArgs e)
        {

            if (chkGenerateSerialNumber.Checked == true)
            {
                Session["NoOfRows"] = txtQty.Value;


                System.Text.StringBuilder sb = new System.Text.StringBuilder();
                sb.Append(@"<script language='javascript'>");
                sb.Append(@"open_win();");
                sb.Append(@"</script>");
                ScriptManager.RegisterStartupScript(this, this.GetType(), "javascript",   sb.ToString(), true);// it does  work but in open_win() method window.open("../Stock/IPurchaseDetail.aspx","_blank","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400"); does not get call
}
}

Now I have got Session["NoOfRows"] = txtQty.Value; but another page does not call.

protected void Page_Load(object sender, EventArgs e)
      {
          if (!IsPostBack)
          {
              NoOfRows Convert.ToInt32((string)HttpContext.Current.Session["NoOfRows"]);

          }

      }

解决方案

Hello,

There are at-least two ways to do that.

1. Similar to your code except that the desired parameters are passed as a Query String. S your code becomes something like one shown below.
   

   function open_win() {
       var s = document.getElementById("txtQty");
       var url = "../Stock/IPurchaseDetail.aspx?txtQty=" + encodeURIComponent(s.value);
       window.open(url, "_blank","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400");
   }

2. This method is very much similar to above, the only difference is that you open a named window with blank url and POST the existing form to that window. Following code snippet shows how this can be done.
   

   function open_win() {
       var hWin = window.open("", "hWinPurchase","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400");
       var frm = document.getElementById('YOUR_FORM_NAME');
       frm.target = "hWinPurchase";
       frm.submit();
   }

Regards,

Add target attribute to form tag thats it, you are done.
Now whenever button is clicked, aspx will open in new window.
Paste the following code in your .ASPX page

<form id="form1" runat="server" target="_blank">

<!-- Add your buttons herere -->

</form>

Go to Tools->Option->Content and uncheck block popup windows.
