//获取当前iframe
function getFrameInParent(){
    var len =  parent.document.getElementsByTagName("iframe").length;
    for(var i = 0; i < len; i++){
        if(parent.document.getElementsByTagName("iframe")[i].contentWindow.document === document){
            return parent.document.getElementsByTagName("iframe")[i];
