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
其實獲取父頁面的一個參數(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：

<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。
