上一页和下一页使用Jquery导航

Question

使用后退和前进链接进行导航控制，以便前进或返回链接列表。当你点击下一步时，它会前进到列表的第一页，但随后停留在那里。 如何将访问链接设置为活动状态，以便顺序进行，即从1到2，然后从2到3等。 感谢您的帮助。

$(document).ready(function() { 
 
      $('.next-button').click(function() { 
 
       var $el = $('#nav li a.navSelected').removeClass('navSelected'); 
 
       var $next = $el.parent().next(); 
 
       if ($next.length == 0) $next = $('#nav li:first'); 
 
       $next.find('a.nav-button').addClass('navSelected');

Answer 1

我创建this捣鼓你。 它与Bootstrap和JQuery。 我不知道如果你知道Bootstrap和JQuery。 如果您还有其他问题，请询问。

1：

var ArrayOfPages = ['One', 'Two', 'Three', 'Four', 'Five']; 
 

 

 
var makeTheRightOneActiveWhenThePageStart = function() { 
 
    var url = window.location.href; 
 
    for (var i = 0; i < ArrayOfPages.length; i++){ 
 
     var newUrl = ArrayOfPages[i] + '.html'; 
 
     if (url.indexOf(newUrl) > 1){ 
 
      var newI = i + 1; 
 
      $("a:contains("+ newI + ")").parent().addClass('active'); 
 
     } } }; 
 

 
var makeTheRightOneActive = function() { var $selector = $(this); var getClass = $selector.attr('class'); var getHTML = $selector.html(); var whatTheSetTrue; switch (getClass){ 
 
     case 'prev': 
 
      whatTheSetTrue = getTheRightOneActiveWhenPressPrevOrNext('prev',getHTML); 
 
      break; 
 
     case 'next': 
 
      whatTheSetTrue = getTheRightOneActiveWhenPressPrevOrNext('next',getHTML); 
 
      break; 
 
     default: 
 
      whatTheSetTrue = getTheRightOneActiveWhenPressPrevOrNext('',getHTML); 
 
      break; } window.open(whatTheSetTrue + '.html', '_self', false) }; 
 

 
var getTheRightOneActiveWhenPressPrevOrNext = function (whatMethode,whichNumber) { 
 
    var whatPageAreYouOn = $('.active').children().html(); 
 
    var whatCurrentPlaceAreYouOn = findAtWhichPlaceYouAreInTheArray(whatPageAreYouOn); 
 
    var newPlace; 
 
    switch (whatMethode){ 
 
     case 'next': 
 
      newPlace = whatCurrentPlaceAreYouOn + 1; 
 
      if (newPlace === 5){ 
 
       newPlace = 4; 
 
      } 
 
      break; 
 
     case 'prev': 
 
      newPlace = whatCurrentPlaceAreYouOn - 1; 
 
      if (newPlace === -1){ 
 
       newPlace = 0; 
 
      } 
 
      break; 
 
     default: 
 
      newPlace = findAtWhichPlaceYouAreInTheArray(whichNumber); 
 
      break; 
 
    } 
 
    return ArrayOfPages[newPlace] }; 
 

 
var findAtWhichPlaceYouAreInTheArray = function (whatPageAreYouOn) { 
 
    whatPageAreYouOn = parseInt(whatPageAreYouOn); 
 
    return whatPageAreYouOn - 1; }; 
 

 
var init = function() { 
 
    makeTheRightOneActiveWhenThePageStart(); 
 
    $('.container .pagination a').on('click',makeTheRightOneActive); }; $(document).ready(init());

编辑1

var ArrayOfPages = ['One', 'Two', 'Three', 'Four', 'Five']; 

这个数组是你的网页的名称数组。这是什么意思，例如你有一个网页称为一，二...

你把这些名字放在数组中。

如果名称不匹配，则不会打开任何网页，也不会使页面处于活动状态，因为它找不到当前页面的名称与 的名称匹配。

我创建了一个Github project创建演示。
