Question

这让我疯狂！

我有一个生成HTML文件的php页面，其中有一些javascript函数会触发一些选择和其他东西。其中一个JS也会生成一个日期，我希望使用Bootstrap Datepicker插件。我不能让它工作，我不知道为什么，因为在其他页面包括相同的CSS和JS它完美的工作......所以，这个页面的错误是什么？请帮忙！

<?php

    session_start();

    require_once ("common/functions.php");

    if (!checkSession()) {
        header('Location: home.php');
        die();
    }

    dbConnect();

    printHeader("Aggiungi Magazzino e Preparazioni");

    printMenu($_SESSION['data']);

    echo "<center><div class='container'><p class='h3'>Aggiungi Magazzino e Preparazioni</p><br>";

    echo "<form method = 'POST' action='home_user.php'>";

    if ($_GET['type'] == "magazzino") {
        #code...
    else {
        $query = "SELECT Nome FROM Pietanza";
        $res = mysql_query ($query) or die ("Error: ".mysql_error());
        for ($j = 0; $result = mysql_fetch_assoc ($res); $j++) {
            $pietanze[$j] = $result['Nome'];
        }

        echo "<label for='nos'>Quante preparazioni vuoi aggiungere?</label>";
        echo "<select class='form-control' name='nos' onchange='addPreparations(this, ".json_encode($pietanze).");'>

在您的情况下，相关事件会在错误的时间添加到选择中：试试这个：

 <script type="text/javascript">
    $(function(){
            $("#sel").change(function(){
                  $('.datepicker').datepicker();
            });
    });
</script>

如何在另一个Javascript中实现Bootstrap Datepicker？
