因此,我正在研究一個帶搜索功能的網頁,用戶可以在其中鍵入事件名稱和朋友的姓名,並且該頁面將顯示基於這些輸入的搜索結果。打印出多個搜索結果

提前道歉,我的代碼是一個絕對亂七八糟的(但它的工作原理,這就是我現在所關心的)但是,我的問題是,我不知道打印出所有搜索結果的好方法。我看着在互聯網上,我有現在有以下幾點:

$('#searchFeedback').empty(); 
$.each(data.events[i], function (index, value) { 
    $('#searchFeedback').append(output); 
}) 

這是我找到的最好的選擇(也是唯一以任何方式工作的一個,即使我在JQuery的混合),但問題是它會重複打印出最後的搜索結果,而不是打印出每個搜索結果。我對JQuery完全無能爲力。

這裏是我的整個JS代碼:

<script> 

        function eventSearch() { 
         var eName = document.getElementById("ename").value; 
         var fName = document.getElementById("fname").value; 
         var searchResults = ""; 
         var friendResults = ""; 
         var attendeeText = ""; 

         if (eName === "" && fName === "") { 

document.getElementById("searchFeedback").innerHTML = "<h4 class='eName'>Fields cannot be empty!</h4>"; 

         } else { 

          for (var i = 0; i < data.events.length; i++) { 

           searchResults = data.events[i].eName.toUpperCase(); 

           var output = "<h4 class='eName'>" + data.events[i].eName + " &bull; " + data.events[i].date + "</h4> <p class='eDesc'>" + data.events[i].description + "<br><sub>" + attendeeText + "<a class='event' onclick='openEventLink(" + i + ");' href=''><b> Check it out here.</b> </a></sub></p><br>"; 

           if (eName != "" && searchResults.includes(eName.toUpperCase())) { 

            if (data.events[i].attendees.length != 1) { 
             for (var a = 0; a < data.events[i].attendees.length; a++) { 
              attendeeText = data.events[i].attendees.join(", "); 
             } 
            } else { 
             attendeeText = data.events[i].attendees; 
            } 


            if (data.events[i].attendees.length > 1) { 
             attendeeText = attendeeText + " are going."; 
            } else if (data.events[i].attendees.length == 1) { 
             attendeeText = attendeeText + " is going."; 
            } else { 
             attendeeText = ""; 
            } 

            if (fName != "") { 
             for (var a = 0; a < data.events[i].attendees.length; a++) { 
              friendResults = data.events[i].attendees[a].toUpperCase(); 
              if (friendResults.includes(fName.toUpperCase())) { 

               console.log(searchResults); 
               console.log(friendResults); 

               $('#searchFeedback').empty(); 
               $.each(data.events[i], function (index, value) { 
                $('#searchFeedback').append(output); 
               }) 

              } 
             } 


            } else { 
             // Print results 
            } 



           } else if (eName == "" && fName != "") { 
            for (var a = 0; a < data.events[i].attendees.length; a++) { 

             if (friendResults.includes(fName.toUpperCase())) { 
              console.log(friendResults); 
              console.log(data.events[i].eName); 

              if (data.events[i].attendees.length != 1) { 
               for (var a = 0; a < data.events[i].attendees.length; a++) { 
                attendeeText = data.events[i].attendees.join(", "); 
               } 
              } else { 
               attendeeText = data.events[i].attendees; 
              } 


              if (data.events[i].attendees.length > 1) { 
               attendeeText = attendeeText + " are going."; 
              } else if (data.events[i].attendees.length == 1) { 
               attendeeText = attendeeText + " is going."; 
              } else { 
               attendeeText = ""; 
              } 

              // Print results 


             } 
            } 
           } 
          } 
         }  
        } 

        /* document.getElementById("searchFeedback").innerHTML = 
               "<h4 class='eName'>" + data.events[i].eName + " &bull; " + data.events[i].date + "</h4> <p class='eDesc'>" + data.events[i].description + "<br><sub>" + attendeeText + "<a class='event' onclick='openEventLink(" + i + ");' href=''><b> Check it out here.</b> </a></sub></p><br>"; */

謝謝你這麼多!

編輯:這是我的數據庫的結構。這裏有更多的東西載入,但是這裏有相關的位。

    "events": [ 
     {

編輯2:我會添加我的表單的HTML,以防萬一它有幫助。

<div class="eventSearch"> 
       <h2>Search for events</h2> 

       <form id="login" onsubmit="return eventSearch()"> 
        <b>By event name:</b> <input type="text" name="ename" id="ename" size="56" placeholder="i.e. The Time War"><br> 
        <b>By a friend's name:</b> <input type="text" name="fname" id="fname" size="50" placeholder="i.e. Rose Tyler"><br><br> 

        <input type="radio" name="dates" value="allDates" checked> All events<br> 
        <input type="radio" name="dates" value="pastDates"> Past events<br> 
        <input type="radio" name="dates" value="futureDates"> Future events<br><br> 

        <button type="submit" id="confSearch" name="confSearch" onclick="event.preventDefault(); eventSearch();"><b>Search</b></button><br><br> 

       </form> 

       <div id="searchFeedback"></div>

由於$('#searchFeedback'),它的打印效果可能只是最後一項。empty();'? – Leguest

刪除該行沒有區別,所以不能這樣。 – Koenshi

好的,那麼'data.events [i]'是什麼?你能在這裏展示嗎? – Leguest

這可惜不起作用。搜索無法正常工作,只會再顯示一個結果。 – Koenshi

我更新了我的答案。做很多重構 – Leguest

這類作品!它按預期方式顯示搜索結果,但它分別搜索兩個輸入,這意味着事件名稱搜索輸出某些事件,並且朋友名稱搜索輸出其他事件,而不是搜索與事件名稱輸入匹配的事件以及朋友名稱輸入。所以現在我有時會得到兩次事件。此外,朋友搜索不能自行工作。 – Koenshi
