弹出窗口，其中textbox_onchange不起作用? [英] pop up windows wherein textbox_onchange doesnt work?

问题描述

您好，程序员在这里遇到了一些我无法解决的错误.
香港专业教育学院设法在我的母版页上添加一个弹出窗口，以便我每次都可以调用它

hello programmers, got a few errors here that I cannot solve myself.
Ive manage to add a pop up window on my master page so that I could call it everytime

<script type="text/javascript">


        function OpenPopup() {
if (window.showModalDialog) {
    window.showModalDialog("PopUp.aspx", "PopUp",
"dialogWidth:550px;dialogHeight:300px");
} else {
window.open('PopUp.aspx', 'name', 'height=300,width=550,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no ,modal=yes');
}
}
    </script>

看到我正在打电话给PopUp，aspx
现在在我的popup.aspx上，这是最棘手的部分
我将其与带有源txtSearchBox的自动完成扩展器绑定在一起

See that I am calling PopUp,aspx
Now on my popup.aspx here is the trickest part
I am binding it with autocomplete extender with the source txtSearchBox

    </form>

看到我的txtSearchbox具有ontextchange和自动回发.现在我可以获取想要的值，但是它不会保留在窗口弹出窗口中，因此它将值转移到新窗口中.

See that my txtSearchbox has ontextchange and auto postback. Now i can get the value i want but then it doesnt remain in the window popup thus it transfer the value to a new window.

Protected Sub txtSearchBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtSearchBox.TextChanged
        txtCourseName.text = txtSearchBox.text    End Sub

使用回调函数.您可以使用window.parent或window.opener在javascript中访问父窗口对象.您可以将变量传递或访问子控件到父窗口或父控件到子窗口的窗口.
了解更多有关网上的信息.

Use callback function. You can access parent window object in javascript by using window.parent or window.opener. You can pass the variables or access the control of child to parent or parent to child window.
