Golang Templates

[Ali Hassan]

<div class="horzontialList" id="List">
	{{range .}}
	{{if ne .Symbol " "}}
	<span>{{.Symbol}}</span>
	{{end}}
	{{end}}

var div=document.getElementById('List');
var point = div.getElementsByTagName('span');

console.log(point[0].innerHTML)

Actual Output: Empty string

Excepted Output: Y 

How to resolve this 

[Brian Candler]

What language is that code written in?  It looks more like Javascript than Go to me.

If you have a problem with some Go code, please can you show the Go code - ideally as a self-contained runnable example at play.golang.org

yes it is https://github.com/ali2210/WizDwarf/blob/master/main.go [line: 150-158]

The next thing to do  is to boil this down to a standalone test case in the golang playground.

Are you saying the template is not being expanded correctly at line 155? https://github.com/ali2210/WizDwarf/blob/master/main.go#L155

Are you sure the value of LifeCode is what you expect? Try printing it at that point.

If it is, then write a small program which sets LifeCode to that fixed value, and expands the template.  If that works, then you know the problem is somewhere else.  If it doesn't work, then you know the problem is with template expansion and someone can help you debug it, because they have the code in the go playground where they can easily edit and test it.
