从子页面获取父页面的价值 [英] Get value in parent page from children page

问题描述

大家好！
我有一个问题，我可以将数据从子页面发送到父页面(在父页面中，我使用masterpage)并显示在标签上，但是当我想在背后的代码中获取价值时，我就无法获取它们.我得到的值始终是标签上的文本名称，我不知道为什么?
你能帮我吗?
这是我的javarscrip，用于将数据从子页面发送到父页面.

Hi every one!

Could u help me?
This my javarscrip to send data to parent page from children page.

function AcceptList() {
    opener.document.getElementById("ctl00_ContentPlaceHodlerMain_myIdLable").getAttribute.innerHTML = a;
    close();
    }

我使用.getAttribute.innerText是相同的结果.

[edit]已添加代码块-OriginalGriff [/edit]

推荐答案

Try

Try

opener.document.getElementById("ctl00_ContentPlaceHodlerMain_myIdLable").innerHTML = a;

或

or

opener.document.getElementById("ctl00_ContentPlaceHodlerMain_myIdLable").setAttribute("innerHTML", a);

您的方法不是专业的ctl00_ContentPlaceHodlerMain_myIdLable.为什么要使用渲染的ID. 无论如何，请尝试以下链接:

Your approach is not professional ctl00_ContentPlaceHodlerMain_myIdLable.Why you are using rendered ID.?
Anyway,try the following links:
