上一頁和下一頁使用Jquery導航

Question

使用後退和前進鏈接進行導航控制，以便前進或返回鏈接列表。當你點擊下一步時，它會前進到列表的第一頁，但隨後停留在那裏。 如何將訪問鏈接設置爲活動狀態，以便順序進行，即從1到2，然後從2到3等。 感謝您的幫助。

Answer 1

我創建this搗鼓你。 它與Bootstrap和JQuery。 我不知道如果你知道Bootstrap和JQuery。 如果您還有其他問題，請詢問。

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());

編輯1

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

這個數組是你的網頁的名稱數組。這是什麼意思，例如你有一個網頁稱爲一，二...

你把這些名字放在數組中。

如果名稱不匹配，則不會打開任何網頁，也不會使頁面處於活動狀態，因爲它找不到當前頁面的名稱與 的名稱匹配。

EDIT 2

我創建了一個Github project創建演示。
