[英]JavaScript/HTML - Set selected tab based on url variable
我有一个搜索页面,并且找到了一个选项卡组件的脚本,该脚本将TV-Show搜索页面和Movie搜索页面分开。 当用户单击时,说“电影”选项卡,然后从那里进行搜索,我将表单添加?type=movie&...
到URL中。 但是,当他们执行搜索时,选定的选项卡是“电视节目”选项卡,并且必须单击以转到具有所需结果的另一个选项卡。
这是代码,其中是我尝试过的一些内容:
HTML看起来像这样:
<article class="first">
<h2>Search</h2>
<hr/>
<div id="tabWrapper">
<div id="tabContainer">
<div class="tabs">
<ul>
<li id="tabHeader_1">TV Shows</li>
<li id="tabHeader_2">Movies</li>
</ul>
</div>
<div class="tabContent">
<div class="tabpage" id="tabpage_1">
<?php
if (isset($sortFilt['year']))
unset($sortFilt['year']);
if ($sortField=="year")
$sortField==" ";
DisplaySearchPage("shows", $terms, $sortField, $sortDir, $sortFilt, $page, $perPage);
?>
</div>
<div class="tabpage" id="tabpage_2">
<?php
DisplaySearchPage("movies", $terms, $sortField, $sortDir, $sortFilt, $page, $perPage);
?>
</div>
</div>
</div>
</div>
</article>
<script src="tabs.js"></script>
这是tabs.js
脚本:
window.onload=function() {
// get tab container
var container = document.getElementById("tabContainer");
// set current tab
var navitem = container.querySelector(".tabs ul li");
//store which tab we are on
var ident = navitem.id.split("_")[1];
navitem.parentNode.setAttribute("data-current",ident);
//set current tab with class of activetabheader
navitem.setAttribute("class","tabActiveHeader");
//hide two tab contents we don't need
var pages = container.querySelectorAll(".tabpage");
for (var i = 1; i < pages.length; i++) {
pages[i].style.display="none";
}
//this adds click event to tabs
var tabs = container.querySelectorAll(".tabs ul li");
for (var i = 0; i < tabs.length; i++) {
tabs[i].onclick=displayPage;
}
// This below is is what I tried.
var selTab = (getUrlVars()["type"] == "movies") ? 2 : 1;
var selTab = (getUrlVars()["type"] == "movies") ? 1 : 0; // Tried this too.
tabs[selTab].click();
// its seems like it should have worked, what am I doing wrong.
}
// on click of one of tabs
function displayPage() {
var current = this.parentNode.getAttribute("data-current");
//remove class of activetabheader and hide old contents
document.getElementById("tabHeader_" + current).removeAttribute("class");
document.getElementById("tabpage_" + current).style.display="none";
var ident = this.id.split("_")[1];
//add class of activetabheader to new active tab and show contents
this.setAttribute("class","tabActiveHeader");
document.getElementById("tabpage_" + ident).style.display="block";
this.parentNode.setAttribute("data-current",ident);
}
如何根据URL参数中的type
变量,使该脚本适应我决定在加载页面时显示哪个选项卡?
我找到了答案。 我的问题是getUrlVars["type"]
,它无法给我' getUrlVars["type"]
变量的值,所以我为此创建了自己的函数。 如果其他人想知道如何从url获取变量,这是工作代码。
function getURLParameter(name)
{
return decodeURI(
(RegExp(name + '=' + '(.+?)(&|$)').exec(location.search)||[,null])[1]
);
}
window.onload = function()
{
// Get tab container
var container = document.getElementById("tabContainer");
// Set the current tab.
var navitem = container.querySelector(".tabs ul li");
// Store which tab is selected.
var ident = navitem.id.split("_")[1];
navitem.parentNode.setAttribute("data-current", ident);
// Set the current tab with a class of 'activetabheader'.
navitem.setAttribute("class", "tabActiveHeader");
// Hide the 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 the click event handler to the tabs.
var tabs = container.querySelectorAll(".tabs ul li");
for (var i = 0; i < tabs.length; i++) {
tabs[i].onclick = displayPage;
}
// Selects tab based on 'type' url variable.
if (getURLParameter("type") == "movies") {
tabs[1].click();
}
}
// OnClick() event handler for tabs.
function displayPage()
{
var current = this.parentNode.getAttribute("data-current");
// Remove class of 'activetabheader' and hide the old contents.
document.getElementById("tabHeader_" + current).removeAttribute("class");
document.getElementById("tabpage_" + current).style.display = "none";
var ident = this.id.split("_")[1];
// Add a 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);
}
