ext.window和iframe传值的问题？

Question

我在ext.window中内嵌了html：<iframe id="myframe" scr="pinter.htm">在ext.window中有个打印预览的按钮                         ｛
        text:"打印预览(O)",
        minwidth:70,
        handler:function()
        {                                           
                          var c = AddPublishwin.body.first().dom.innerHTML;
                          var printer = AddPublishwin.body.last().dom.contentWindow;
                          printer.document.body.innerHTML = c;
                          printer.focus();
                          printer.print();
        }
}var c = AddPublishwin.body.first().dom.innerHTML;//这个是取整个window的所有html代码 
但是现在我只想取window中的所有文本框的值 给iframe 打印!怎么做呢？

var inputs = document.getElementsByTagName("input"), arr = [];

Ext中var textArr = win.findByType("textfield"), arr = [];
for (var i = 0; i < textArr.length; i++) {
    arr.push(textArr[i].getValue());
}
document.getElementById("myframe").innerHTML = arr.toString();
