Question

我是PHP＆amp;的新手Javascript因此可能有很多菜鸟错误 - 我试图将4个php变量（例如'温和活跃'）传递给具有指定值的Javascript，然后在Javascript图表上绘制它们。关于我哪里出错的任何建议？图表的标签永远不会移动，例如Active＆amp;反思，因为它们是对立的，它们的价值保持在维度1。将值传递给图表的最有效方法是什么？提前谢谢。

<?php

    $dbQuery = $db->prepare("select dimension1, dimension2, dimension3, dimension4 FROM indexLearningStyle WHERE studentNumber = '".$currentUser."'");
    $dbQuery-> execute();

    while ($dbRow = $dbQuery->fetch (PDO::FETCH_ASSOC)) {
    $dimension1 = $dbRow["dimension1"];
    $dimension2 = $dbRow["dimension2"];
    $dimension3 = $dbRow["dimension3"];
    $dimension4 = $dbRow["dimension4"]; 

    }

    $stronglyActive = 0;
    $moderatelyActive = 0.16;
    $mildlyActive = 0.32;

    $stronglyReflective = 1.0;
    $moderatelyReflective = 0.84;
    $mildlyReflective = 0.68;

    $stronglySensing = 0;
    $moderatelySensing = 0.16;
    $mildlySensing = 0.32; 

    $stronglyIntuitive = 1.0;

    $stronglyVisual = 0;
    $moderatelyVisual = 0.16;
    $mildlyVisual = 0.32;

    $stronglyVerbal = 1.0;
    $moderatelyVerbal = 0.84;
    $mildlyVerbal = 0.68;

    $stronglySequential = 0;
    $moderatelySequential = 0.16;
    $mildlySequential = 0.32;

    $stronglyGlobal = 1.0;
    $moderatelyGlobal = 0.84;
    $mildlyGlobal = 0.68;

正如@Lawrence所说，你应该使用array＆amp;正确的标签。

以下是您应该尝试的简单代码：

<?php
    //Fetch following values and assign to array
    $stronglyGlobal = 1.0;
    $moderatelyGlobal = 0.84;
    $mildlyGlobal = 0.68;
?>
<!-- Correct opening/closing body-->
<div id="studentILS"></div>
<!-- scripts -->
<script src="https://code.jquery.com/jquery-3.0.0.min.js"></script>
<script src="cssBipolarChart.js"></script>

<script>
    //Loop through PHP array & print var in JavaScript
    var stronglyGlobal = <?php echo $stronglyGlobal ?>; //Notice echo over here
    var moderatelyGlobal = <?php echo $moderatelyGlobal ?>;
    var mildlyGlobal = <?php echo $mildlyGlobal ?>;

    var studentResults = [
        ["Sequential", "Global", mildlyGlobal], //Updated values assigned
        ["Sequential", "Global", stronglyGlobal],
        ["Sequential", "Global", moderatelyGlobal]
    ]

    $(document).ready(function() {
        $("#studentILS").drawCSSBipolarChart({
            data: studentResults,
            bipolar: true
        })
    })
</script>

希望这个答案能给你提示。
