在您的标记中设置最初的活动链接:
<a target="iframe1" class="menu_active" href="gallery/photo_menu.html">PHOTOGRAPHY</a>
然后在您的set_menu
函数中,将iframe
'src
属性设置href
为该链接的属性:
for (i in lnk) {
if (lnk.hasOwnProperty(i)) {
//lnk[i].className = 'menu_idle'; // initial menu states are set in markup. This line is no longer necessary.
lnk[i].onclick = hlite_menu;
if (lnk[i].className === 'menu_active') {
iframe.src = lnk[i].href;
}
}
}
我还强烈建议将您的 JavaScript 重写为以下内容:
var hlite_menu = function hlite_menu() {
'use strict';
var lnk = document.getElementById('menu').getElementsByTagName('a'),
i = null;
//set all links to idle
for (i in lnk) {
if (lnk.hasOwnProperty(i)) {
lnk[i].className = 'menu_idle';
}
}
//set this link to active
this.className = 'menu_active';
},
set_menu = function set_menu() {
'use strict';
var lnk = document.getElementById('menu').getElementsByTagName('a'),
iframe = document.getElementById('iframe1'),
c = document.getElementById('copyright'),
i = null;
// set copyright
c.innerText = (new Date()).getFullYear();
// set onclicks and initial iframe src.
for (i in lnk) {
if (lnk.hasOwnProperty(i)) {
//lnk[i].className = 'menu_idle'; // initial menu states are set in markup. This line is no longer necessary.
lnk[i].onclick = hlite_menu;
if (lnk[i].className === 'menu_active') {
iframe.src = lnk[i].href;
}
}
}
};
window.onload = set_menu;
这避免了几个长期问题,例如可读性/维护、变量提升和可怕的document.write
(您用于设置版权日期)。您还需要将版权部分更改为:
<div id="footer">
ALL IMAGES © <span id="copyright"></span>
</div>
您也可以像这样编写导航(避免使用表格进行布局):
<div id="header">
<div class="logo">
<span style="">MO SCHALKX</span>
</div>
<div id="menu">
<a target="iframe1" class="menu_active" href="gallery/photo_menu.html">PHOTOGRAPHY</a>
<a target="iframe1" class="menu_idle" href="gallery/film_menu.html">FILM</a>
<a target="iframe1" class="menu_idle" href="about.html">ABOUT</a>
<a target="iframe1" class="menu_idle" href="http://reflecture.tumblr.com">BLOG</a>
</div>
</div>
并将其添加到您的 CSS 中:
#header {
float: left;
display: inline-block;
margin: 1em;
text-align: center;
}
.logo, #menu {
background-color: #FFF;
}
.logo {
font-size: 40px;
font-weight: 500;
font-style: inherit;
}
#menu {
margin-top: 5px;
}
#menu > a {
padding-left: 0.25em;
}
#menu > a {
border-left: 1px solid #000;
}
#menu > a:first-child {
border-left: none;
}
这应该使它看起来一样。您还可以将您的 CSS 规则与menu_active
and a:hover
(同样与menu_idle
and a:visited
)结合起来,如下所示:
a.menu_idle, a:visited {
color: #333333;
text-decoration: none;
}
a.menu_active, a:hover {
color: #333333;
text-decoration: underline;
}
最后,您已将您的元素包装iframe
在一个<form id="form1" runat="server">
元素中。您可以完全删除它。它不会影响您的布局,并且您实际上没有包含任何input
元素的表单,因此没有必要。此外,runat="server"
除非您在 ASP.Net 上运行该属性(显然您不是),否则该属性不会做任何事情,因此您可能需要牢记这一点。
总而言之,您应该能够将整个文档源更改为以下内容,而无需进行真正的视觉更改(我认为您会发现在源中查看它要干净得多):

UDPATE
要在http://moschalkx.nl/gallery/film_menu.html上应用它,只需包含相同的 JavaScript 并注释掉涉及设置版权set_menu
和更新的id
行iframe
:
var hlite_menu = function hlite_menu() {
'use strict';
var lnk = document.getElementById('menu').getElementsByTagName('a'),
i = null;
//set all links to idle
for (i in lnk) {
if (lnk.hasOwnProperty(i)) {
lnk[i].className = 'menu_idle';
}
}
//set this link to active
this.className = 'menu_active';
},
set_menu = function set_menu() {
'use strict';
var lnk = document.getElementById('menu').getElementsByTagName('a'),
iframe = document.getElementById('gallery'),
//c = document.getElementById('copyright'),
i = null;
// set copyright
//c.innerText = (new Date()).getFullYear();
// set onclicks and initial iframe src.
for (i in lnk) {
if (lnk.hasOwnProperty(i)) {
//lnk[i].className = 'menu_idle'; // initial menu states are set in markup. This line is no longer necessary.
lnk[i].onclick = hlite_menu;
if (lnk[i].className === 'menu_active') {
iframe.src = lnk[i].href;
}
}
}
};
window.onload = set_menu;
此外,由于您在此页面上包含 jQuery,因此您可以在 jQuery 中将其编写为:
$(document).ready(function () {
$('#menu a').click(function (e) {
var self = $(this),
href = self.attr('href');
$('#menu a').not(self).removeClass('menu_active').addClass('menu_idle');
self.removeClass('menu_idle').addClass('menu_active');
$('#gallery').attr('src', href);
});
});
