问题描述
我正在尝试使用kotlinx.html构建html布局页面。我可以创建主页，但是在将其分解为由单独功能生成的部分时遇到问题。我不知道如何将在单独函数中创建的html包含到主文档中。
我在使用不安全方面取得了成功，但我认为应该有更好的方法
我的单元测试如下：
import kotlinx.html.*
import kotlinx.html.stream.appendHTML
import kotlinx.html.stream.createHTML
import org.junit.jupiter.api.Test
class TestHtmlDsl {
fun html(): String {
val stringBuffer = StringBuffer()
stringBuffer.appendHTML().html {
head {
}
body {
h1 { +"Head lines" }
div {
id = "main div"
div {
strong {+"sub div"}
}
getDiv1()
getDiv2()
}
}
}
return stringBuffer.toString()
}
fun getDiv1(): DIV.() -> Unit {
return {
p { +"first try" }
}
}
fun getDiv2(): String {
return createHTML().div {
p { +"second try" }
}
}
@Test
fun testHtml() {
println(html())
}
}
它产生输出：
<html>
<head></head>
<body>
<h1>Head lines</h1>
<div id="main div">
<div><strong>sub div</strong></div>
</div>
</body>
</html>
两个带有段落的divs
我正在此服务器端（jvm）运行。我在js中找到了一些示例，但没有运气
我很想在某个地方为kotlinx找到更好的文档

返回函数，因此您需要调用它：# Make predictions on test data batch using the loaded full model
test_predictions = loaded_full_model.predict(test_data,verbose=1)

返回getDiv1()，因此您需要附加它：getDiv1()()（请注意，HTML中的所有保留字符（例如getDiv2()，String）都会被字符实体（+getDiv2()，<）替换，因此无论如何您都不会选择这种方式
