javascript - 如何使用php获取jquery id值？

<script>
function startTimer(duration, display) {
    var timer = duration,
        minutes, seconds;

    interval = setInterval(function() {
        minutes = parseInt(timer / 60, 10)
        seconds = parseInt(timer % 60, 10);

        minutes = minutes < 10 ? "0" + minutes : minutes;
        seconds = seconds < 10 ? "0" + seconds : seconds;

        display.text(minutes + ":" + seconds);

        if (--timer < 0) {
            alert("Time has ended");
            $("#registration-form").submit()
            clearInterval(interval);
        }
    }, 1000);

    return new Date();
}

jQuery(function($) {
    s = 10;
    var Minutes = 60 * s,
        display = $('#time');

    var startDate = startTimer(Minutes, display);

    $('button').click(function() {
        var now = new Date();
        var seconds = (now.getTime() - startDate.getTime()) / 1000;
        $('#runtimes').append('<p>' + seconds + '</p>');
    })
});

</script>
<div class="col-md-4">

    <div class="test">Time Left <span id="time"></span>min</div>
</div>

<form name="frmRegistration" id="registration-form" method="post" action="index1.php">
  <div id="runtimes" name="runtime"></div>
<button>Get run time</button>

</form>

 在链接中显示单击按钮时已运行时间的值，我需要通过POST传递div ID值，并将其传递到另一页中，然后将该值插入db，但未通过传递值，这有助于我如何获取div ID值

最佳答案

您可以在表单中添加隐藏的输入，并在需要时更新其值。

的HTML

<input type="hidden" id="valueoftime" name="valueoftime">

jQuery查询

 $('button').click(
        var now = new Date();
        var seconds = (now.getTime() - startDate.getTime()) / 1000;
        $('#runtimes').append('<p>' + seconds + '</p>');

       //Update input val
        $("#valueoftime").val(seconds);
    })
