javascript - 将变量传递给另一个页面上的函数

转载作者：行者123 更新时间：2023-12-03 04:06:25

我正在开发一个网站，并计划拥有它，以便某些链接将设置一个值，这将更改页面加载时显示的容器。我怎样才能让链接传递一个用于 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">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</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>

这是我的制表函数:

function tabulate(tabNum){
$('.recipe').each(function() {
    if(tabNum==this.id){
        this.style.display="block";
    }
    else{
        this.style.display="none";
    }
});

}

最佳答案

您需要使用 URL 的 GET parameters :

lunch.html?item=2

结合将变量传递到 JavaScript 函数中:

// 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";
    }
  });
}
