请教text template中的变量处理问题

我给的链接下面就是 example啊,这个也需要我贴么…… package main import ( "log" "os" "strings" "text/template" ) func main() { // First we create a FuncMap with which to register the function. funcMap := template.FuncMap{ // The name "title" is what the function will be called in the template text. "title": strings.Title, } // A simple template definition to test our function. // We print the input text several ways: // - the original // - title-cased // - title-cased and then printed with %q // - printed with %q and then title-cased. const templateText = ` Input: {{printf "%q" .}} Output 0: {{title .}} Output 1: {{title . | printf "%q"}} Output 2: {{printf "%q" . | title}} ` // Create a template, add the function map, and parse the text. tmpl, err := template.New("titleTest").Funcs(funcMap).Parse(templateText) if err != nil { log.Fatalf("parsing: %s", err) } // Run the template to verify the output. err = tmpl.Execute(os.Stdout, "the go programming language") if err != nil { log.Fatalf("execution: %s", err) } } template里可以传入FuncMap,里面是转换函数。 然后在模板里调用转换函数转换

正常做法 ,你需要写一个filter。 https://golang.org/pkg/text/template/#FuncMap temlate文档中本身也有
