我目前正在处理CodeIgniter图表,但收到的错误如下:
Uncaught SyntaxError: Unexpected token <
并且图表未加载显示空白.
var data_course_stats = google.visualization.arrayToDataTable([
['Course', 'Time spent',{ role: 'style' }],
<?php
$i=0;
foreach ($timespent_stats as $course) { $course = (object)$course;
$color_val = 'green';
if(count($i<count($timespent_stats)))
$color_val = $colors[$i++];
?>
['<?php echo $course->title;?>', <?php echo $course->spent_seconds/60;?>,'<?php echo $color_val; ?>'],
<?php } ?>
]);
var options_course_stats = {
title: 'Course Wise Spent Time in Minutes',
curveType: 'function',
height: 400,
bar: {groupWidth: "50%"},
legend: { position: "none" },
};
最佳答案 虽然你已经接受了答案,但我想添加另一种技术,它比前一种技术简单得多.你可以用<?= like<?php echo something执行echo; ?>所以你可以简单地执行此操作<?= something?>
<?php
$i=0;
foreach ($timespent_stats as $course) {
$course = (object)$course;
$color_val = 'green';
if(count($i<count($timespent_stats)))
{
$color_val = $colors[$i++];
?>
[<?= $course->title ?>, <?= $course->spent_seconds/60 ?>, <?= $color_val ?>]
<?php
}
}
?>
