點擊圖示(而不是按鈕的其餘部分)是 Javascript 訂閱按鈕工作的唯一方法。

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:

$clicked_btn = $(this);
let $icon = $clicked_btn.find('i').first();

if ($icon.hasClass("fa-solid fa-rss")) {
    action = "subscribe";
} else if ($icon.hasClass("fa-solid fa-user-check")) {
    action = "unsubscribe";
}
