通过URL访问特定标签

问题描述

我在Internet上的jQuery中找到了一个标签系统，但是创建它(并授权使用它)的人现在不再可以联系，所以这就是为什么我在这里问这个问题.

I found a tab system in jQuery on the internet but the guy who made it (and authorized it's use) isn't available for contact anymore, so this is why I ask this question here.

这是我的javascript的代码，用于管理不同的标签.

This is the code of my javascript that manages the different tabs.

window.onload=function() {​



// get tab container
  var container = document.getElementById("tabContainer");
    if (document.location.hash.length) {
        $('.tabs ul li a[href^="' + document.location.hash + '"]').click();
    }
// set current tab
var navitem = container.querySelector(".tabs ul li");
//store which tab we are on
var ident = navitem.id.split("_")[1];
navitem.parentNode.setAttribute("data-current",ident);
//set current tab with class of activetabheader
navitem.setAttribute("class","tabActiveHeader");

//hide two tab contents we don't need
var pages = container.querySelectorAll(".tabpage");
for (var i = 1; i < pages.length; i++) {
  pages[i].style.display="none";
}

//this adds click event to tabs
var tabs = container.querySelectorAll(".tabs ul li");
for (var i = 0; i < tabs.length; i++) {
  tabs[i].onclick=displayPage;
}
}

// on click of one of tabs
function displayPage() {
  var current = this.parentNode.getAttribute("data-current");
  //remove class of activetabheader and hide old contents
  document.getElementById("tabHeader_" + current).removeAttribute("class");
  document.getElementById("tabpage_" + current).style.display="none";

  var ident = this.id.split("_")[1];
  //add class of activetabheader to new active tab and show contents
  this.setAttribute("class","tabActiveHeader");
  document.getElementById("tabpage_" + ident).style.display="block";
  this.parentNode.setAttribute("data-current",ident);
}

这是HTML:

            <div class="tabs">
            <ul>
                <li id="tabHeader_1">Les listes</li>
                <li id="tabHeader_2">Les membres</li>
            </ul>
        </div>
<div class="tabscontent">
            <div class="tabpage" id="tabpage_1">
                <h2>Les listes</h2>
                <p>Pellentesque habitant morbi tristique senectus...</p>
            </div>
            <div class="tabpage" id="tabpage_2">
                </div>

默认情况下，JavaScript会加载第一"标签(tabHeader_1，tabpage_1).我想要的是，例如，如果我将网址放在example.com/page.php#tabpage_2中，它将自动加载第二个标签.

By default, the javascript loads the FIRST tab (tabHeader_1, tabpage_1). What I'd like is if I put for example in the url example.com/page.php#tabpage_2, it loads automatically the second tab.

非常感谢您的帮助.

推荐答案

document.location.hash返回带有数字符号(#hash)的哈希.
您也不能使用.tabs ul li a作为选择器，因为li内没有a标记.

document.location.hash returns the hash with the number sign (#hash).
You also can't use .tabs ul li a as the selector because there is no a tag inside of the li.

尝试使用:

var hash = document.location.hash.substr(1); // skip 1 character (the number sign)
$('.tabs ul li[id^="' + hash + '"]').click();

此外，该脚本不是in jQuery.在整个脚本中，它仅使用1个jQuery函数.我认为这比jQuery更纯净的JavaScript.

Also, this script isn't in jQuery. It only uses 1 jQuery function throughout the whole script. I would consider this more pure JavaScript than jQuery.
