求助dialog父子页传值,在Chrome下如何实现?

以前有一个类似的看一下
dialog这样定义的

 $("#materialBtn").click(function(){
        var api = frameElement.api, W = api.opener;
        W.dialog({
            id: 'dialog2',
            content:'url:$!{main_static_url}/ledMaterial/linkToLedMaterialSetting',
                        

chrome

    if($.browser.msie) {
        child = window['window'].document.frames["ledDialog"];
} else {
        child = window.window.frames["ledDialog"];
}

ie

if($.browser.msie) {
    child = window['top'].document.frames["dialog2"];
} else {
    child = window.top.frames["dialog2"];
}
