我有一個訂閱使用者個人資料按鈕,只有當我單擊 rss font Awesome 圖示時才起作用,而按鈕的其餘部分則不起作用。我嘗試了幾次重寫,將按鈕元素設為單擊事件,但它們根本不起作用。
以下程式碼僅在點擊圖示元素時起作用:
<button class='subscribe-button profile-subscribe'> <?php if ($profile->userSubscribed): ?> <i class="fa-solid fa-user-check subscribe" data-user='<?= esc($profile->username);?>'></i>Subscribed <?php else: ?> <i class="fa-solid fa-rss subscribe" data-user='<?= esc($profile->username);?>'> </i> Subscribe <?php endif ?> </button>
<script> $(document).ready(function() { var csrfName = "<?= csrf_token(); ?>"; var csrfHash = "<?= csrf_hash(); ?>"; // If user clicks the subscribe button $(".subscribe").on("click", function () { var userProfile = $(this).data("user"); $clicked_btn = $(this); if ($clicked_btn.hasClass("fa-solid fa-rss")) { action = "subscribe"; } else if ($clicked_btn.hasClass("fa-solid fa-user-check")) { action = "unsubscribe"; } $.ajax ({ url: "<?= base_url(); ?>/users/members/view_profile/<?= $profile->username;?>", type: "post", dataType: "json", data: { [csrfName]: csrfHash, "action": action, "user_profile": userProfile, }, headers: { 'X-Requested-With': 'XMLHttpRequest', }, success: function(data) { var res = data; csrfName = res.csrfName; csrfHash = res.csrfHash; if (action == "subscribe") { $clicked_btn.removeClass("fa-solid fa-rss"); $clicked_btn.addClass("fa-solid fa-user-check"); } else if (action == "unsubscribe") { $clicked_btn.removeClass("fa-solid fa-user-check"); $clicked_btn.addClass("fa-solid fa-rss"); } } }); }); }); </script>
這是讓整個按鈕可點擊的一種嘗試:
<button class='subscribe-button profile-subscribe subscribe' id='<?= esc($profile->username); ?>'> <i class="fa-solid fa-rss"></i> Subscribe </button>
<script> $(document).ready(function() { var csrfName = "<?= csrf_token(); ?>"; var csrfHash = "<?= csrf_hash(); ?>"; // If user clicks the subscribe button $(".subscribe").on("click", function (event) { var userProfile = this.id; $clicked_btn = $(this); if ($clicked_btn.hasClass("fa-solid fa-rss")) { action = "subscribe"; } else if ($clicked_btn.hasClass("fa-solid fa-user-check")) { action = "unsubscribe"; } $.ajax ({ url: "<?= base_url(); ?>/users/members/view_profile/<?= $profile->username;?>", type: "post", dataType: "json", data: { [csrfName]: csrfHash, "action": action, "user_profile": userProfile, }, headers: { 'X-Requested-With': 'XMLHttpRequest', }, success: function(data) { var res = data; csrfName = res.csrfName; csrfHash = res.csrfHash; if ($('.subscribe').hasClass('subscribed')) { $('.subscribe').removeClass('subscribed'); $('.subscribe').html('<i class="fa-solid fa-rss"</i>Subscribe'); } else { $('.like').addClass('subscribed'); $('.like').html('<i class="fa-solid fa-user-check">Subscribed'); } } }); }); }); </script>
您的想法是正確的,更改您的點擊處理程序以選擇按鈕而不是圖標,但您錯過了之後的步驟,該步驟正在更改您檢測單擊的是“訂閱”還是“取消訂閱”的方式。當您按一下處理程序位於圖示上時,該類別直接位於已點擊的元素上,但是當您變更為父按鈕時,您必須向下選擇按鈕的子級以查看圖示上的類別以確定它是否是「訂閱」 」或「取消訂閱」。這應該是一個簡單的修復:
