Jquery 在附加新 html 后未检测到点击

Question

我有一个正在使用实时搜索功能的文本框。测试 HTML 效果很好，单击它就会像应有的那样添加到日志中。问题是，一旦我使用搜索框并且新的“相同”代码被附加到 #tag-result 中，单击功能就会停止工作。我使用此代码的相同变体来做其他事情，并且它始终工作完美......除了在这种情况下。

例如，这个确切的代码，将“标签”关系替换为“用户”，效果非常好。

// .blur was missed in original edit of this post...
$('#txttagSearch').blur(function() {
    $(this).val('');
    $('#tag-search-results').hide();
})

// remove above code and replace with the following
$(document).mouseup(function(e) {
    $('#txtTagSearch').val('');
    $('#tag-search-results').hide();
})

// now clicks register and search results hide when they should.

<div class="form-floating">
    <input type="text" class="form-control" id="txtTagSearch" name="txtTagSearch" placeholder="Search to Add Tags" autocomplete="off">
    <label for="txtTagSearch">Search to Add Tags</label>
</div>
<div class="tag-wrapper">
    <div id="tag-search-results">
        <ul id="tag-result">
            <li class="tag-search-click 5">leather</li> /* this click works */
        </ul>
    </div>
    <div class="row gx-2 mt-3">
        <div class="col" id="tag-display">
            <div class="tag" style="background-color: #000;">sunglasses</div>
        </div>
    </div>
</div>

$('#txtTagSearch').keyup(function() {
    liveSearchTag($(this).val())
    $('#tag-search-results').show();
})

$('#model-tag-results #tag-result').mousedown(function(e) {
    e.preventDefault();
})

function liveSearchTag(keyword) {
    $.ajax({
        url: 'server/tag-search.php',
        type: 'GET',
        data: { keyword: keyword },
        dataType: 'json',
        success: function(result) {
            const divTagResult = $('#tag-search-results #tag-result');
            let html = '';
            if (result !== null) {
                if (result.length > 0) {
                    $.each(result, function(index, item) {
                        html += '<li class="tag-search-click ' + item['id'] + '">' + item['tag'] + '</li>' // these clicks do not detect?
                    })
                } else {
                    let html = '<li style="padding: 10px;">NO RESULT FOUND</li>';
                }
            } else {
                let html = '<li style="padding: 10px;">NO RESULT FOUND</li>';
            }
            divTagResult.html(html);
        }
    })
}

$('#tag-search-results').on('click','.tag-search-click',function() {
    console.log('test');
    var tagID = $(this).attr('class').replace('tag-search-click ','');

    $.ajax({
        url: 'server/tag-result.php',
        type: 'GET',
        data: { code: tagID },
        dataType: 'json',
        success: function(data) {
            $('#tag-display').append('test');
            $('#txtTagSearch').val('');
            $('#txtTagSearch').blur();
            $('#tag-search-results').hide();
        }
    })
})

尝试使用多次点击方法...

$('#tag-search-results').on('click','.tag-search-click',function() {
$(document).on('click','.tag-search-click',function() {
$('.tag-search-click').(function() {

我在原帖中遗漏了一些

jQuery

。点击时的

.hide()

并不是导致点击未注册的原因。

.blur()

和

.hide()

导致了问题。下面是我错过的错误代码，以及我现在用来隐藏和清除搜索结果的代码。现在一切都很顺利。希望这会有所帮助。谢谢弗拉兹！！
