I have seen many solutions to this question on this site. However, nothing I try seems to be working.
我在这个网站上看到了很多关于这个问题的解决方案。但是,我尝试的任何东西似乎都没有用。
In my php file I have this:
在我的php文件中我有这个:
<?php
$monthlycalories = "[1, 1364, 1052, 922, 1, 1, 10, 1, 10, 10, 10, 265]";
?>
<script type="text/javascript">
var test = "<?php echo $monthlycalories; ?>";
</script>
In my javascript file I have this:
在我的javascript文件中,我有这个:
$(function () {
var example = test;
alert(example);
$('#monthly').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Monthly Calorie Intake'
},
xAxis: {
categories: [
'Jan',
'Feb',
'Mar',
'Apr',
'May',
'Jun',
'Jul',
'Aug',
'Sep',
'Oct',
'Nov',
'Dec'
]
},
yAxis: {
min: 0,
title: {
text: 'Calories'
}
},
tooltip: {
headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
pointFormat: '<tr><td style="color:{series.color};padding:0"></td>' +
'<td style="padding:0"><b>{point.y:.1f} Calories</b></td></tr>',
footerFormat: '</table>',
shared: true,
useHTML: true
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: 'Months',
data: example
}]
});
});
The javascript is a chart. I have been able to pass the info into the javascript file. I have used the alert()
function and can see that it indeed brought the variable over. However, when I use the example
variable in the javascript it does not work. Furthermore, if I copy over the alert results and replace data: example
with data: [1, 1364, 1052, 922, 1, 1, 10, 1, 10, 10, 10, 265]
then it works.
javascript是一个图表。我已经能够将信息传递到javascript文件中。我已经使用了alert()函数,可以看到它确实带来了变量。但是,当我在javascript中使用示例变量时,它不起作用。此外,如果我复制警报结果并替换数据:示例与数据:[1,1,364,1052,922,1,1,10,1,10,10,10,265]然后它的工作原理。
I can't understand why the variable example
will not work but the chart works fine if you enter the info manually?
我无法理解为什么变量示例不起作用,但如果您手动输入信息,图表工作正常?
