下次調用功能時顯示上一個文本？

Question

在我的項目中，下次調用函數時需要顯示以前的文本嗎？ 我的代碼是..

HTML代碼是：-

<div id="notes">
    <textarea rows="21" cols="38" id="notes_id" placeholder="Enter your notes here..." onclick="current_time('videoPlayer')" onblur="play_video()" >
    </textarea>
</div>

JavaScript的： -

function current_time (player_id) {             
    var player = _V_(player_id);
    var secs = player.currentTime();
    var hours = Math.floor(secs / (60 * 60));

    var divisor_for_minutes = secs % (60 * 60);
    var minutes = Math.floor(divisor_for_minutes / 60);

    var divisor_for_seconds = divisor_for_minutes % 60;
    var seconds = Math.ceil(divisor_for_seconds);

    var time    = hours+ '::' +minutes+ '::' +seconds;
    player.pause();
    document.getElementById("notes_id").value = "Current Time :- " +time+ "\n";
}

Answer 1

您可以簡單地使用+=而不是= ，因此在單擊時，文本將被添加到當前內容中：

document.getElementById("notes_id").value += "\nCurrent Time :- " +time+ "\n";
