钛：使用导航栏的WebView

我用的是钛。 我正在尝试用导航栏显示网页

var main_win = Ti.UI.createWindow({
});

var w = Titanium.UI.createWindow({  
    backgroundColor:'#fff',
    leftNavButtonLabel:'back',

});
var navGroup = Ti.UI.iPhone.createNavigationGroup({
  window:w
});

var backBtn = Titanium.UI.createButton({
      title:'Back',
   style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});

var webView = Titanium.UI.createWebView({
    url : 'http://gooogle.com',
    canGoBack : true,
});

backBtn.addEventListener( 'click', function() {
    webview.goBack();// Goes back one entry in the web view's history list. to the previous page.

});

w.add.setLeftNavButton(backBtn);

w.add(webView);

main_win.add(navGroup);

main_win.open();

for Navigation new window


         navGroup.open(Window name);

for Closing last open window;

         navGroup.close(Window name);

我想把后退按钮放在导航栏的左上角，它是浏览器的背面

var main_win = Ti.UI.createWindow({
});

var w = Titanium.UI.createWindow({  
    backgroundColor:'#fff',
    leftNavButtonLabel:'back',

});
var navGroup = Ti.UI.iPhone.createNavigationGroup({
  window:w
});

var backBtn = Titanium.UI.createButton({
      title:'Back',
   style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});

var webView = Titanium.UI.createWebView({
    url : 'http://gooogle.com',
    canGoBack : true,
});

backBtn.addEventListener( 'click', function() {
    webview.goBack();// Goes back one entry in the web view's history list. to the previous page.

});

w.add.setLeftNavButton(backBtn);

w.add(webView);

main_win.add(navGroup);

main_win.open();

for Navigation new window


         navGroup.open(Window name);

for Closing last open window;

         navGroup.close(Window name);

下面是我当前的代码

var main_win = Ti.UI.createWindow({
});

var w = Titanium.UI.createWindow({  
    backgroundColor:'#fff',
    leftNavButtonLabel:'back',

});
var navGroup = Ti.UI.iPhone.createNavigationGroup({
  window:w
});

var backBtn = Titanium.UI.createButton({
      title:'Back',
   style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});

var webView = Titanium.UI.createWebView({
    url : 'http://gooogle.com',
    canGoBack : true,
});

backBtn.addEventListener( 'click', function() {
    webview.goBack();// Goes back one entry in the web view's history list. to the previous page.

});

w.add.setLeftNavButton(backBtn);

w.add(webView);

main_win.add(navGroup);

main_win.open();

for Navigation new window


         navGroup.open(Window name);

for Closing last open window;

         navGroup.close(Window name);

有人能帮我吗

var main_win = Ti.UI.createWindow({
});

var w = Titanium.UI.createWindow({  
    backgroundColor:'#fff',
    leftNavButtonLabel:'back',

});
var navGroup = Ti.UI.iPhone.createNavigationGroup({
  window:w
});

var backBtn = Titanium.UI.createButton({
      title:'Back',
   style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});

var webView = Titanium.UI.createWebView({
    url : 'http://gooogle.com',
    canGoBack : true,
});

backBtn.addEventListener( 'click', function() {
    webview.goBack();// Goes back one entry in the web view's history list. to the previous page.

});

w.add.setLeftNavButton(backBtn);

w.add(webView);

main_win.add(navGroup);

main_win.open();

for Navigation new window


         navGroup.open(Window name);

for Closing last open window;

         navGroup.close(Window name);

提前谢谢

 var w = Titanium.UI.createWindow({  
    backgroundColor:'#fff',
    leftNavButtonLabel:'back',});
var navGroup = Ti.UI.iPhone.createNavigationGroup({
  window:w
});

var backBtn = Titanium.UI.createButton({
      title:'Back',
   style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});

var webView = Titanium.UI.createWebView({
    url : 'http://gooogle.com',
    canGoBack : true,
});

backBtn.addEventListener( 'click', function() {
    webview.goBack();
});

w.add.setLeftNavButton(backBtn);

w.add(webView);

w.add(navGroup);

w.open();

w.navGroup.open();

var main_win = Ti.UI.createWindow({
});

var w = Titanium.UI.createWindow({  
    backgroundColor:'#fff',
    leftNavButtonLabel:'back',

});
var navGroup = Ti.UI.iPhone.createNavigationGroup({
  window:w
});

var backBtn = Titanium.UI.createButton({
      title:'Back',
   style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});

var webView = Titanium.UI.createWebView({
    url : 'http://gooogle.com',
    canGoBack : true,
});

backBtn.addEventListener( 'click', function() {
    webview.goBack();// Goes back one entry in the web view's history list. to the previous page.

w.add(webView);

main_win.add(navGroup);

main_win.open();

试试看，这个。。。或

var main_win = Ti.UI.createWindow({
});

var w = Titanium.UI.createWindow({  
    backgroundColor:'#fff',
    leftNavButtonLabel:'back',

});
var navGroup = Ti.UI.iPhone.createNavigationGroup({
  window:w
});

var backBtn = Titanium.UI.createButton({
      title:'Back',
   style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});

var webView = Titanium.UI.createWebView({
    url : 'http://gooogle.com',
    canGoBack : true,
});

backBtn.addEventListener( 'click', function() {
    webview.goBack();// Goes back one entry in the web view's history list. to the previous page.

});

w.add.setLeftNavButton(backBtn);

w.add(webView);

main_win.add(navGroup);

main_win.open();

for Navigation new window


         navGroup.open(Window name);

for Closing last open window;

         navGroup.close(Window name);

这是完全错误的编码…非常感谢！我学习了很多，alos通过使用tabgroup学会了如何管理。不管怎样，这对我帮助很大！
