关键点:
1 window.iframeMap = data.iframeMap;
把js方法中的局部变量转变成父页面的全局变量。
2 window.iframeWin = windowlayero.find('iframe')[0];
这里的iframeWin指向的是子页面。得到iframe页的窗口对象,执行iframe页的方法:iframeWin.method();
3 onClick="window.parent.iframeWin.initIframeMap(window.parent.iframeMap['"+i+"']);"
如果是要在父页面的js中调用子页面的js方法initIframeMap ,直接使用iframeWin.initIframeMap 就可以了,参数也能直接传递过去。
