网上查到iframe 的刷新用 location.reload(),不过在我的extjs环境中location未定义

添加tab方法:

var addtab = function (id, title, iconCls, url, closable)
if (!Ext.getCmp(id)) {
var close = true;
if (closable != null) {
close = closable;
}
var content = '<iframe scrolling="auto" frameborder="0" id="iframe_' + id + '" src="' + url + '" style="width:100%;height:100%;"></iframe>';
var page = tabpage.add({
id: id,
title: title,
iconCls: iconCls,
closable: close,
autoScroll: true,
html: content,
// loader: {
// url: url,
// loadMask: true,
// autoLoad: true,
// scripts: true,
// listeners: {
// exception: function (lo, response, options, e) {
// page.setHtml(response.responseText);
// }
// }
// }

刷新方法:

function refreshTab(tab)
var html = tab.config.html;
var iframe = frames['iframe_' + tab.config.id];
var src = iframe.src;
iframe.src = '';
iframe.src = src;
}

将src重置一下即可刷新,tab是tabpage.getActiveTab()得到的当前活动页面
