Question

我最近开始重组一个网站，目前使用的是框架和框架集。

我现在采用了典型的 structure.html ：

<body>
<div>
    <div id="headerNavigation"></div>
    <div id="PageContent"></div>
    <div id="footer"></div>
</div>
</body>
</html>

使用以下jQuery脚本填充DIV：

<head>
<script>
$.get('PageHeader.html', processHeader, "html").fail(function() { alert("There is a problem loading the header. Please re-try"); });
function processHeader(file_data)
{
    $("#headerNavigation").html(file_data);
}

$.get('TermsConditions.html', processContent, "html").fail(function() { alert("There is a problem loading a resource. Please re-try"); });
function processContent(file_data)
{
    $("#PageContent").html(file_data);
}

$.get('Footer.html', processFooter, "html").fail(function() { alert("There is a problem loading a resource. Please re-try"); });
function processFooter(file_data)
{
    $("#Footer").html(file_data);
}
</script>
</head>

当我指定Content页面时，这很有用，但是，我需要某种jQuery函数，当我点击导航菜单中的项目时，它会使用正确的内容转发/填充DIV - index.html ：

<html>
<head>
<!-- jQuery code for drop down nav menus  -->
<script type="text/javascript"> 
    $(document).ready(function(){        
        $('nav li ul').hide().removeClass('fallback');
        $('nav li').hover(
            function () {
                $('ul', this).stop().slideDown(300);
            },
            function () {
                $('ul', this).stop().slideUp(300);
            }
        );       
    });
</script>

</head>

Answer 1

您可以为菜单中的每个链接添加对此函数的调用：

<a onclick="$.get('Information.html', processContent, 'html')" >Information</a>

如您所见，您将重复使用第一次加载内容的相同功能：

$.get('Information.html', processContent, 'html')

通过这种方式，您刚刚调用了相同的'processContent'，但是要加载不同的页面。您可以通过添加第三个函数来简化onclick事件，该函数将由onclick（或href）调用，然后将调用该函数来加载内容，如下所示：

<a onclick="gofor('Information.html')">Information</a>

或者这个：

<a href="javascript:gofor('Information.html')">Information</a>

然后添加这个简单的函数：

function gofor(page){    
    $.get(page, processContent, 'html').fail(function() { alert('There is a problem loading a resource. Please re-try');});
}

显然你不能使用这个功能来加载外部内容，因为它被浏览器禁止

您的索引页面应该是这样的，请注意id为“pageContent”的div，其中将加载页面以及您需要在页面中加载内容所需的功能。

Answer 2

您无需通过javascript加载所有这些元素。事实上，我认为这是不好的做法。您正在进行不必要的通话，这会导致访问者的加载时间更长。标准做法是加载您的初始内容，然后根据需要使用javascript来响应用户命令。

我理解你要将内容分成单独的部分（页眉，页脚等等），但这通常不是这样做的。有一些模板引擎可以完成你想要实现的功能而无需额外的ajax调用来引入常规的html内容。以下是分离可重用内容的一些基本示例：

PHP（服务器端）：

<?php include 'pageheader.html'; ?>
<div>My main content</div>
<?php include 'footer.html'; ?>

Handlebars.js（客户端）

{{>pageheader}}
<div>My main content</div>
{{>footer}}

话虽如此，如果你绝对必须坚持使用当前的设置，那么你只需要从a标签中解析出url并将其发送到你的processContent函数。以下是如何使用jquery执行此操作的示例：

$('li').on('click', function (e) {
    var url = $(this).find(">:first-child").attr('href');
    $.get(url, processContent, "html").fail(function() { alert("There is a problem loading a resource. Please re-try"); });
});

上面的代码基本上只绑定每个li的click事件，并在将该值传递给processContent函数之前获取标记的href值
