Question

我正在尝试运行我的第一个播放应用程序，但似乎我错了。我得到编译错误 play.api.templates.HtmlFormat.Appendable不接受参数在D：\ PlayProjects \ HelloJava \ app \ views \ index.scala.html

index.scala.html

 @(message: String)(level:Int, list:Seq[String])
    @main("Welcome to Play Framework") {    
        <div class="well">
            <h1>@message</h1>       
            @listContainer{
                <h@level>Level @level </h@level>
                    }(level, list){ //this curly brace is error point
                        <div>footer</div>
                    }
        </div>
    }

listContainer.scala.html

@(header:Html)(level:Int , items:Seq[String]) (footer:Html)
<h@level>Here we go ! </h@level>
<div style="margin-left:@{5*level}%">
    @header
        <ul id="list@level" style="margin-left: @{5*level}%" >
            @items.map {item =>
                <li>@item</li>
                }
        </ul>
    @footer
</div>

编制结果：

在摆弄我的代码之后我找到了答案：D

@(header:Html)(level:Int , items:Seq[String])(footer:Html)

我删除了“Seq [String]）”和（页脚：HTML）之间的空格来修复问题。猜猜参数定义之间不应该有任何空格。
