为什么我的代码会从一个html页面重定向到另一个html页面?

时间:2015-07-10 22:44:55

标签: javascript html http-redirect

我尝试在3秒延迟后使用javascript重定向,但我的代码目前什么也没做。 index.html应该在3秒延迟后重定向到menupage.html,但没有任何反应。 menupage.html上有4个按钮:"设备运动"使用Phonegap的加速计和指南针显示设备的速度和方向,其他3只在Phonegap的应用程序内浏览器中打开新页面。这是代码:

编辑:这只是一个文件位置错误。重定向有效。谢谢!

应该是

window.location.href = "http://yoursite.com/menupage.html";

似乎导致重定向的逻辑无法正常工作。您正在正文标记onload中定义<body onload="redirect()">句柄,问题是当该命令执行时,重定向函数尚不存在,因为您正在文档的末尾加载js(是正确的)。你可以做两件事。

  1. 鉴于您的脚本已经结束,只有在浏览器下载了html和js后,才会在脚本末尾调用函数,其行为与onload事件类似。

    // At the end of scripts.js
    // ... omitted for brevity ...
    function openGoogle() {
        window.open('www.google.com', '_blank', 'location=yes');
    }
    
    // simply call the function
    redirect();
    
  2. 通过跨浏览器兼容性正确捕获window.onload事件已知是一场噩梦。幸运的是,jQuery修复了这个问题,因此你可以使用它的初始化程序,以防你拥有它或者可以包含jQuery。

    $(function(){
        // this only happens when the document is ready!
        redirect();
    });
    
  3. 最后你的重定向功能看起来应该是这样的

    function redirect() {
        window.setTimeout(function() {
            window.location.href = "menupage.html";
            // if you need to replace a part of the current url
            // for example going from http://example.com/summer/index.html
            // to http://example.com/winter/index.html you can
            // window.location.href = window.location.href.replace('summer', 'winter');
        }, 3000)
    }

您是否尝试过使用php重定向?我相信它会更容易使用。

header( "refresh:3;url=menupage.html" );
