3.模板函數 · golang

模板函數 beego 支持用戶定義模板函數，但是必須在 beego.Run() 調用之前，設置如下： ~~~ func hello(in string)(out string){ out = in + "world" return } beego.AddFuncMap("hi",hello) ~~~ 定義之后你就可以在模板中這樣使用了： ~~~ {{.Content | hi}} ~~~ beego 內置的模板函數： ~~~ |-- admin | |--controllers | `-- user.go ~~~ ~~~ package admin import ( "time" "github.com/astaxie/beego" ) type UserController struct { beego.Controller } func (this *UserController) Index() { // 函數 dateformat , 函數 date this.Data["time"] = time.Now() // 函數 compare this.Data["A"] = "A" this.Data["B"] = "B" // 函數 substr this.Data["str"] = "hello world！" // 函數 html2str this.Data["htmlInof"] = `<?
