我是一位有用的助手，可以帮您进行文本翻译。
我开发了Jira报表插件。Velocity模板在Java字符串中显示ASCII代码的单引号或双引号。
Java代码：
Main:
Map velocityParams = new HashMap();
String horizontalAxis = convertKeysToWeekCategories(bugtrends.keySet());
velocityParams.put("horizontalAxis", horizontalAxis);
convertKeysToWeekCategories method:
StringBuilder build = new StringBuilder();
for (Integer integer : keySet) {
build.append("\'");
build.append("W");
build.append(integer.toString());
build.append("\'");
build.append(",");
}
String result = build.toString();
result = result.substring(0, result.length() - 1);
return result;
}
And I draw with HighChart api.
bugstrendview.vm:
<head >
<meta charset="utf-8">
</head>
<script>AJS.$(document).ready(function(){
chart = new Highcharts.Chart({
chart: {
type: 'spline',
renderTo: 'container'
},
exporting: {
enabled: true,
filename: "open-bugs-trend-chart"
},
title: {
text: 'Open Bugs Trend',
x: -20 //center
},
subtitle: {
text: 'results are displayed in weeks',
x: -20 //center
},
xAxis: {
categories: [$horizontalAxis],
labels: {
rotation: -90,
align: 'right',
style: {
fontSize: '13px',
fontFamily: 'Verdana, sans-serif'
}
}
},
tooltip: {
formatter: function() {
var myDates = $tooltipDates;
return "<b>W"+(this.point.x+1)+"</b><br/>"+
myDates[this.point.x]+" - "+myDates[this.point.x + 1]+
"<br/>"+"Total Bugs : "+this.point.y ;
},
},
yAxis: {
gridLineWidth: 1,
minorGridLineWidth: 1,
title: {
text: 'Number of Open Bugs'
},
min: 0,
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
plotOptions: {
spline: {
dataLabels: {
enabled: true
},
marker: {
enable: true
}
}
},
series: [
{
showInLegend: false,
data: [$verticalAxis]
}]
}); });
</script>
在bugstrendview.vm中显示的类别为：'W1'，错误为“未捕获的SyntaxError：意外的标记&'”，当然也不会绘制。
为什么显示单引号的ASCII码？
