子页面C#后台代码：

复制代码 代码如下:

/// <summary>

/// 将设置好的值赋给父页面

/// </summary>

/// <param name="count">需要传递的值</param>

void SetValueToParentPage(int count, string strPersons)

{

StringBuilder jsStr = new StringBuilder();

jsStr.Append(" var retValue = new Object();");

if (count == 0)

{

jsStr.AppendFormat("retValue = null;");

}

else

{

jsStr.AppendFormat("retValue.Nums='{0}';", count);

jsStr.AppendFormat("retValue.Names='{0}';", strPersons);

}

jsStr.Append("window.returnValue = retValue;window.close();");

ClientScript.RegisterStartupScript(GetType(), "close", jsStr.ToString(), true);

}

父页面前台js：

复制代码 代码如下:

function OpenPerChoose(url) {

var openobj = window;

if (typeof (window.dialogArguments) == "object") {

openobj = window.dialogArguments;

}

var returnValue = showPopWin(url, 800, 600, openobj);

if (returnValue != null) {

document.getElementById("<%=txtQualifiedNums.ClientID %>").value = returnValue.Nums;

}

}

复制代码 代码如下:

//弹出窗口

function showPopWin(url, width, height, returnFunc) {

width = parseInt(width) + 30;

height = parseInt(height) + 30;

return window.showModalDialog(url + "&Datetime=" + GetTime(), document, "dialogWidth:" + width + "px;dialogHeight:" + height + "px;help:0;status:0;scroll:auto;center:1;resizable:1;");

}
