jquery - codeigniter、jQuery Mobile、jQuery UI - 脚本未在首次加载时加载,仅刷新

我对我的 codeigniter 应用感到困惑。

我有一个 View /表单( View 1),它在提交时加载另一个 View ( View 2)。 View 1,在初始页面加载时未加载正确的 js 和 css。它改为从 View 1 加载 js 和 css。如果我随后在 View 2 上点击刷新,则会加载正确的 css 和 js。

为了证明我的观点我放置了一个测试js脚本

<script type='text/javascript'>
alert('test');
</script>

作为 View 1 和 View 2 上的第一位代码。在第一次加载 View 1 时,会显示警报,当我在 View 1 上单击提交并加载 View 2 时,不会显示警报。如果我根据需要刷新警报显示。

因此 js 和 css 在初始加载时无法正确加载,但在刷新时可以完美运行。

有什么想法吗?

初始页面加载 - 没有警报或 js/css 工作 - 只有来自 View 1 的 css 和 js enter image description here

刷新加载 - View 1 中没有 css 或 js,仅加载 View 2 css 和 js。请注意,我已经从 View 2 中删除了所有样式,只是为了测试和开始工作。所以下图是我想要的。此处显示警报。这是关闭警报后的加载。 enter image description here

我在 IE、Firefox 和 Chrome 中都试过了,结果都一样。

欢迎任何建议。谢谢

最佳答案

首先,您的代码中存在一个大问题。使用 jQuery Mobile 时,初始化 javascript/jquery 代码的唯一正确方法是 jQuery Mobile 页面事件。如果您使用 document ready$(function(){ 来初始化您的代码,它很有可能会失败是因为:

  • 有时,像这样使用的 javascript 会在页面加载到 DOM 之前触发。这就是它在刷新后工作的原因,内容已经在 DOM 中。
  • 即使页面加载到 DOM 中,jQuery Mobile 仍然需要使用自己的样式和标记来增强它们。

为防止这种情况,强烈建议使用 jQuery Mobile 页面事件。这是一个有效的 jsFiddle 示例:http://jsfiddle.net/Gajotres/tuJEm/

$(document).on('pageshow', '#index', function(){       
alert('Page loaded');
});

$(document).on('pagebeforeshow', '#second', function(){
alert('Page loaded');
});

为了使其适用于您的情况,您需要为您的页面容器提供一个 id:

<div  data-role="page"  data-theme="a">

如果您想更好地理解这一点,请查看此 ARTICLE ,或找到它 HERE .

还有一件事,由于 jQM 页面事件,您不再需要在 HTML 文件末尾加载脚本。无论如何,如果是 jQM,您的 jQm js 和 css 应该始终在您的 html header 中。

编辑:

在调查 jQuery Mobile + Codeigniter 问题后。我无法确认这是否有效,但您应该尝试一下。显然,codeigniter 在 jQuery Mobile 如何通过 AJAX 处理页面加载方面存在问题。所以基本建议是将其关闭。

您需要做的第一件事是将您所有的脚本和样式标签移到 HEAD 中。每个 PHP 文件都应该有相同的一组 jQuery、jQuery Mobile js 文件加载到头部。这样做是因为我们将阻止页面加载到 DOM 中,并且每个页面都将作为一个实体存在。

第二件事,ajax 页面加载:

<script>
$(document).bind("mobileinit", function() {
$.mobile.ajaxEnabled = false;
});
</script> <!-- Note your script before jqm -->

还有一点,mobilinit 事件必须在 jQuery 之后但在 jQuery Mobile 之前初始化,像这样:

<script src="jquery.js"></script>
<script>
$(document).bind("mobileinit", function() {
$.mobile.ajaxEnabled = false;
});
</script> <!-- Note your script before jqm -->
<script src="jquery-mobile.js"></script>
