當我單擊一個按鈕時，我只想在另一個元素包含特定文本時才顯示一個元素

Question

例如，當我單擊按鈕 (class="button") 時，如果 class="test1" 包含文本“Select”，它將顯示 class="test2"。

<input class="button" type="button" value="Button"></input>
<div class="test1">Select</div>
<div class="test2">12345</></div>

Answer 1

<div class="test1">Select</div>
<div class="test2" hidden>12345</div>
<div class="test1">Select</div>
<div class="test2" hidden>54321</div>
<div class="test1">hide</div>
<div class="test2" hidden>67890</div>
<input class="button" type="button" value="Button"></input>
<script src="https://code.jquery.com/jquery-3.5.0.js"></script>
<script type="text/javascript">
    $('.button').on('click',function(){
        $.each($('.test1'), function(key, value){
        var tdValue = $(value).text();
            console.log(value, key);
        if (tdValue == 'Select'){
            $(value).next('.test2').show();
            $(value).hide();
        }else{
            $(value).next('.test2').hide();
            $(value).hide();
        }
        });
    });
</script>
