最近經(jīng)常用到iframe,，用的最多的就是在子頁面中操作父頁面的方法或變量等,，總結(jié)了用到的幾種方法，如下：
var tableName = window.parent.frames["mainFrame"].tName;//獲取父頁面的參數(shù)值
window.parent.frames["mainFrame"].getPageInfo();//父頁面的方法
var divValue = window.parent.$("#test").text(); (jQuery); //獲取父頁面div的文本值
var htmlUrl = window.parent.$("#main_frame").attr("src");(jQuery)//獲取父頁面的iframe的src屬性值
其實(shí)獲取父頁面的一個(gè)參數(shù)或方法有很多種的寫法,，現(xiàn)在拿獲取父頁面的iframe的src屬性值為例，現(xiàn)在先看主頁面的html代碼：

<!-- 內(nèi)容區(qū) -->
<iframe id="main_frame" name="mainFrame" class="ui-layout-center" width="100%"
height="100%" frameborder="0" scrolling="auto" src="MainFrame.aspx"></iframe>
<div class="ui-layout-south">
</div>
</body>
</html>
要獲取iframe的src的值的話，可以在子頁面MainFrame.aspx中用這幾種方法獲?。?/P>
var htmlUrl = window.parent.$("#main_frame").attr("src"); (jQuery)//獲取父頁面的iframe的src屬性值
var htmlUrl = window.parent.$("#main_frame").attr("src");(jQuery)
var htmlUrl = window.parent.$("iframe[name='mainFrame']").attr("src");(jQuery)
var htmlUrl = window.parent.document.getElementById("main_frame").src;
var htmlUrl = window.parent.frames["mainFrame"].location;
var htmlUrl = window.parent.$("[name='mainFrame']").attr("src");
這是自己用到的，應(yīng)該還會有很多的方法,，ok先這樣吧,。
