如何鏈接到其他頁面上特定的JavaScript選項卡？

Question

我正嘗試從目錄頁面鏈接到頁面上的特定選項卡。我似乎無法找到一種方法來做到這一點對我來說很有意義。忍受我，因爲我是相當新的寫JavaScript。

我使用的是這個HTML。

<ul id="tabs"> 
     <li><a href="#website">Website</a></li> 
     <li><a href="#facebook">Facebook</a></li> 
     <li><a href="#twitter">Twitter</a></li> 
     <li><a href="#blog">Blog</a></li> 
     <li><a href="#pub">Pub/Marketing</a></li> 
    </ul> 
    <div class="tabContent" id="website"><!--=================== Tab 1 ===================-->

     <p>Bounce rate is indicative of a massive improvement: the current website has a 40% bounce rate.</p>

和JavaScript如下：

var tabLinks = new Array(); 
var contentDivs = new Array();

    //Grab the tab links and content divs from the page 
    var tabListItems = document.getElementById('tabs').childNodes;

      var id = getHash(tabLink.getAttribute('href'));

Answer 1

那麼等待我想出了添加幾行的JavaScript的解決答案。對於那些需要它的人來說，這裏是最終版本。

var tabLinks = new Array(); 
var contentDivs = new Array(); 

function init() { 
//Grab the tab links and content divs from the page 
var tabListItems = document.getElementById('tabs').childNodes; 
for (var i = 0; i < tabListItems.length; i++) { 
    if (tabListItems[i].nodeName == "LI") { 
     var tabLink = getFirstChildWithTagName(tabListItems[i], 'A'); 
     var id = getHash(tabLink.getAttribute('href')); 
     tabLinks[id] = tabLink; 
     contentDivs[id] = document.getElementById(id); 
    } 
} 

//Assign onclick events to the tab links, and 
//highlight the first tab 
var i = 0; 

for(var id in tabLinks) { 
    tabLinks[id].onclick = showTab; 
    tabLinks[id].onfocus = function() { this.blur()}; 
    if (i == 0) tabLinks[id].className = 'selected'; 
    i++; 
} 

//Hide all content divs except the first 
var i = 0; 

for(var id in contentDivs) { 
    if (i !=0) contentDivs[id].className='tabContent hide'; 
    i++; 
} 

//Show linked tab 
if (document.location.hash) showTab(document.location.hash.substring(1)); 
} // end of init function 

// ShowTab Function 

function showTab(selectedId) { 
if (typeof selectedId != 'string') var selectedId = getHash(this.getAttribute('href')); 

//Highlight the selected tab, and dim all others. 
//Also show the selected content div, and hide all others. 
for (var id in contentDivs) { 
    if (id == selectedId) { 
     tabLinks[id].className = 'selected'; 
     contentDivs[id].className = 'tabContent'; 
    } else { 
     tabLinks[id].className =''; 
     contentDivs[id].className = 'tabContent hide'; 
    } 
} 

//Stop the Browser following the link. 
return false; 
} //end of showTab function 

function getFirstChildWithTagName(element, tagName) { 
for (var i = 0; i < element.childNodes.length; i++) { 
    if (element.childNodes[i].nodeName == tagName) return element.childNodes[i]; 
} 
} 

function getHash(url) { 
var hashPos = url.lastIndexOf('#'); 
return url.substring(hashPos + 1); 
}
