使用Beego / GoLang在模板内插入JavaScript代码段

问题描述：

What is the best method to insert a javascript snippet into a template for Golang using the Beego framework?

Currently, I am just adding data to a template:

c.Data["Javascript"] = JavasciptStringObject

And in a script.tpl file adding insertion points:

 var canvas = new fabric.Canvas('c');
 canvas.setHeight(571); //todo: Set to height of image
 canvas.setWidth(991);
 {{.JavaScript}}

The problem is that it escapes the quotation marks from the string, rather than injecting directly in:

var canvas = new fabric.Canvas('c');
canvas.setHeight(571); 
canvas.setWidth(991);
"var path = new fabric.Path('M 617 141 L 606 126M 606 126 L 604 127 z', { stroke: 'red', strokeWidth: 2, fill: false, originX: 'left', originY: 'top',});canvas.add(path); "

Some useful resources include Golang HTML Templating Doc, which apparently Beego models: https://golang.org/pkg/html/template/

And this stack overflow seems to be getting closer, I don't think this will work with Beego: Go lang templates: always quotes a string and removes comments

使用Beego框架将JavaScript代码段插入Golang模板的最佳方法是什么？ p>

当前，我只是向模板中添加数据： p>

  c.Data [“ Javascript”] = JavasciptStringObject 
  code>   pre> 
 
 并在script.tpl文件中添加插入点： p> 
 
 
  var canvas = new fabric.Canvas（'c'）; 
 canvas  .setHeight（571）;  // todo：设置为图片的高度
 canvas.setWidth（991）; 
 {{.JavaScript}} 
  code>  pre> 
 
 问题是它逃脱了  p> 
 
 
  var canvas = new fabric.Canvas（'c'）; 
canvas.setHeight（571）;而不是直接在字符串中加上引号。  
canvas.setWidth（991）; 
“ var path = new fabric.Path（'M 617141 L 606 126M 606 126 L 604127z'，{stroke：'red'，strokeWidth：2，fill：false，originX  ：'left'，originY：'top'，}）; canvas.add（path）;“ 
  code>  pre> 
 
 一些有用的资源包括Golang HTML模板文档，显然 Beego模型： https://golang.org/pkg/html/template/    p> 
 
 
这个堆栈溢出似乎越来越近了，我认为这不适用于Beego：转到lang模板：始终引用字符串并删除注释  p>

The answer was

 import "html/template"

 //within function
 c.Data["Javascript"] = template.JS(JavasciptStringObject)

Note: template.JSEscape did not work.
