Question

$('.delete').click(function() {
    $('.pop-up-alert').addClass('clicked');
    function() {
        if ($('.no-btn').click()) {
            $('.pop-up-alert').removeClass('clicked');
        } else if ($('.yes-btn').click()) {
            $(.delete).parent().remove();
        } else {
            $('.pop-up-alert').removeClass('clicked');          
        };
    };
});

我需要在其他地方回显$ ActiveWeekEndingDate，如何在函数外部正确访问它。

编辑：

我设法让它与以下人员合作但是准备声明是不是真的必要呢？

function GetActiveWeek($mysqli, $ActiveWeekEndingDate) {
    $stmt = "SELECT ParameterValue FROM INF_WebConfig WHERE ParameterName = 'ActiveWeekEndingDate'";
    $ActiveWeekEndingDate = $mysqli->query($stmt);
    return $ActiveWeekEndingDate;
}

Answer 1

为什么不在回复中处理它？</ p>

$ActiveWeekEndingDate = GetActiveWeek();
echo $ActiveWeekEndingDate;

如果你坚持让它全球化（不鼓励），请在函数上面添加：

global $ActiveWeekEndingDate;

Answer 2

您需要将GetActiveWeek函数的返回值分配给您可以从函数中访问的变量。

function GetActiveWeek($mysqli, $ActiveWeekEndingDate) {
        $stmt = "SELECT ParameterValue FROM INF_WebConfig WHERE ParameterName = 'ActiveWeekEndingDate'";
        $ActiveWeekEndingDate = $mysqli->query($stmt);
        return $ActiveWeekEndingDate;
}

$retVal = GetActiveWeek($mysqli, $ActiveWeekEndingDate);

Answer 3

function GetActiveWeek($mysqli) {
    $stmt = $mysqli->prepare("SELECT ParameterValue FROM INF_WebConfig WHERE ParameterName = 'ActiveWeekEndingDate'"); 
    $stmt->execute();
    $stmt -> bind_result($ActiveWeekEndingDate);
    $stmt -> fetch();
    $stmt -> close();
    $mysqli -> close();
    return $ActiveWeekEndingDate;
}

这就是我取得成果的方式。我只是调用初始化变量的函数。
