我正在开发一个网站,并且我正在计划使用它以便某些链接具有值集,这将更改页面加载时显示的容器。我怎么能拥有它,以便链接传递一个可用于onload函数的值?
这是我的HTML代码的模型:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Lunch</title>
<link rel="stylesheet" type="text/css" href="style.css">
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script src="script.js"></script>
</head>
<body onload="navBar(); dateChange(); tabulate(0);">
<nav>
<ul>
<li><a href="appy.html">Appitizers</a></li>
<li><a href="break.html">Breakfast</a></li>
<li><a href="lunch.html">Lunch</a></li>
<li><a href="dinner.html">Dinner</a></li>
<li><a href="dessert.html">Dessert</a></li>
<li><a href="special.html">Ten-Course Dinner</a></li>
<li><a href="share.html">Send in your Recipes!</a></li>
</ul>
</nav>
<div class="main">
<div class="box">
<ul>
<li><a onclick="tabulate(this.id);" id="1">Chicken Clubhouse Sandwiches</a></li>
<li><a onclick="tabulate(this.id);" id="2">Smokey Tomato Soup</a></li>
</ul>
</div>
<div id="0" class="recipe" style="display: block;">
<div class="tabs">
<a class="tab"> </a>
</div>
<div class="page">
<p>The recipes you'll find here are ones you can use to impress guests at your next get together</p>
</div>
</div> <!--recipe card end-->
<div class="recipe" id="1">
<h1>Chicken Clubhouse Sandwiches</h1>
</div> <!--recipe card end-->
<div class="recipe" id="2">
<h1>Smokey Tomato Soup</h1>
</div> <!--recipe card end-->
</div>
</body>
</html>
这是我的制表功能:
function tabulate(tabNum){
$('.recipe').each(function() {
if(tabNum==this.id){
this.style.display="block";
}
else{
this.style.display="none";
}
});
}

您需要使用网址GET
parameters:
lunch.html?item=2
结合将变量传递给JavaScript函数:
// Set up an object for GET parameter
var $_GET = {};
// Find and extract the various GET parameters
if(document.location.toString().indexOf('?') !== -1) {
var query = document.location.toString().replace(/^.*?\?/, '').replace(/#.*$/, '').split('&');
for(var i=0, l=query.length; i<l; i++) {
var aux = decodeURIComponent(query[i]).split('=');
$_GET[aux[0]] = aux[1];
}
}
// Target a specific get parameter, given the GET parameter name
var tabNum = $_GET['item']; // Comes through as '2' in this example
// Pass the parameter into the function
function tabulate(tabNum){
$('.recipe').each(function() {
if(tabNum==this.id){
this.style.display="block";
}
else{
this.style.display="none";
}
});
}
请参阅this post和 this post 以获取进一步的参考。
希望这有帮助! :)

我没有对此进行过测试,但您应该可以通过PHP将GET变量传递给tabulate(),方法如下:
function tabulate(tabNum){
$('.recipe').each(function() {
if(tabNum==this.id){
this.style.display="block";
}
else{
this.style.display="none";
}
});
}
window.addEventListener('DOMContentLoaded', function(evt) {
var id = <?php echo htmlspecialchars($_GET['id'], ENT_COMPAT, 'utf8'); ?>;
tabulate(id);
});
