英文:
Date.Format for javascript date
问题
我有一个从appengine数据存储加载的数组，其中包含以下结构：
struct {
Date time.Time
PostedSample int
}
我想将其输出到html/template中，以便用于<a href="https://developers.google.com/chart/interactive/docs/gallery/annotatedtimeline#Data_Format">Google Visualization Time Line</a>。首先，我尝试在模板中直接使用{{.Date.Format "new Date(2006,1,2,15,4,5)"}}来格式化日期，但是html/template会对此进行转义，因此它在html源代码中显示为带引号的字符串。然后，我尝试将日期格式化为[]struct{Date template.JS; Value template.JS}，使用表达式template.JS(m.Date.Format("new Date(2006,1,2,15,4,5)"))，这几乎可以工作，只是月份减少了一个，因为JavaScript中的一月是0。我可以让模板生成日期参数的JSON，并编写JavaScript将其转换为Date对象，或者使用Go代码调整模板输出。请分享一个更优雅的解决方案。谢谢。
英文:
I have an array of
struct {
Date time.Time
PostedSample int
}
loaded from the appengine datastore which I want to output in a html/template for the <a href="https://developers.google.com/chart/interactive/docs/gallery/annotatedtimeline#Data_Format">Google Visualization Time Line</a>. First I tried formatting the Date directly in the template with {{.Date.Format "new Date(2006,1,2,15,4,5)"}} but html/template escapes this so it appears as a quoted string in the html source. I then tried formatting the date into a []struct{Date template.JS; Value template.JS} with the expression template.JS(m.Date.Format("new Date(2006,1,2,15,4,5)")) which almost works except the month is off by one, javascript wants January as 0. I could have the template generate a json of date parameters and write javascript turn that into Date objects or have go code which adjusts the template output. Please share a more elegant solution. Thank you.

你不需要在模板中添加格式化函数。
你可以像这样使用你的结构体：
{{.Date.Format "Mon 2 Jan 2006"}}
解决方案可能是这样的：
var date = new Date(parseInt({{.Date.Nanosecond }} /1000));
英文:
You don't need to add a format function to the templates.
You can use your struct like so:
{{.Date.Format "Mon 2 Jan 2006"}}
The solution might be something like this:
var date = new Date(parseInt({{.Date.Nanosecond }} /1000));
