对我 进行编码
"); -//原样显示html片断自身，不作为html元素进行渲染 -display(view); - -//显示被html编码过的原始字符串 -display(view.ToString()); -``` -这就是HTML方法派上用场的地方。如果你想将一个字符串传递给PocketView，但又不希望它被HTML编码，你可以简单地将该字符串用HTML方法包裹起来： -```csharp -//HTML方法后，就作为 html片断进行 "渲染" 了 -PocketView view2 = span(HTML("
Don't encode me!
")); -display(view2); -display(view2.ToString()); -``` -HTML简单地将一个字符串捕获到一个实现IHtmlContent接口的实例中。该接口用于指示该值不应被HTML编码，而是应被视为有效的HTML并直接呈现。 - -了解了这一点，可能不会感到惊讶的是，PocketView本身也实现了IHtmlContent接口。 - -你还可以将其他类型的对象传递给PocketView。当你这样做时，它们会使用纯文本格式化器进行格式化，该格式化器默认会扩展对象的属性。 -```csharp -PocketView view3 = b( - new {Fruit="apple", Texture="smooth"} -); - -display(view3) -``` -由于目前.NET Interactive的格式化API不支持为嵌套的HTML片段生成格式化器，PocketView会回退到text/plain格式化器来描述传递对象的属性。 - -你也可以将对象列表传递给PocketView。这对于从数据生成HTML非常有用： -```csharp -var fruits = new []{"apple","banana","cherry"}; -var colors = new []{"green","#F1C40F","red"}; - - -ul( - fruits.Zip(colors).Select(x => li[style:$"color:{x.Item2}"](x.Item1)) -) -``` -总结：其实这样的方式 "组装"html页面或片断，会非常繁琐；只适合临时做一些简单的html组装； -方案： -+ 使用 html 内核: 但有个最大问题是"html内核不能使用共享数据"；只适合纯静态页面； -+ 使用 javascript 内核: 虽然能使用 "共享数据"功能，但js内核长处是操作现有html并非生成html; -+ 使用 razor 或 blazor 库，像razor或blazor页面或组件一样，就非常方便了;`非常推荐的终极解决方案` 唯一缺点是智能提示差，可以在VS里写好，粘贴过来哈； -使用 Razor的例子:体验下方不方便（后面专题讲解） -```csharp -#r "nuget:RazorInteractive" -``` -```razor -#!razor -@{ - - var dic = new Dictionary() - { - {"apple","green"}, - {"banana","#F1C40F"}, - {"cherry","red"}, - }; -} - - -``` diff --git a/Docs/多语言笔记.1.2.魔法命令.ipynb b/Docs/多语言笔记.1.2.魔法命令.ipynb new file mode 100644 index 0000000..43ca76d --- /dev/null +++ b/Docs/多语言笔记.1.2.魔法命令.ipynb @@ -0,0 +1,38 @@ +{ + "cells": [ + { + "cell_type": "markdown", + "id": "a78e177e", + "metadata": { + "polyglot_notebook": { + "kernelName": "csharp" + } + }, + "source": [ + "使用魔法命令\n", + "===========" + ] + } + ], + "metadata": { + "kernelspec": { + "display_name": ".NET (C#)", + "language": "C#", + "name": ".net-csharp" + }, + "polyglot_notebook": { + "kernelInfo": { + "defaultKernelName": "csharp", + "items": [ + { + "aliases": [], + "languageName": "csharp", + "name": "csharp" + } + ] + } + } + }, + "nbformat": 4, + "nbformat_minor": 5 +} diff --git a/Docs/多语言笔记.1.4.使用NuGet包.ipynb b/Docs/多语言笔记.1.4.使用NuGet包.ipynb new file mode 100644 index 0000000..e78ba35 --- /dev/null +++ b/Docs/多语言笔记.1.4.使用NuGet包.ipynb @@ -0,0 +1,38 @@ +{ + "cells": [ + { + "cell_type": "markdown", + "id": "065bfcac", + "metadata": { + "polyglot_notebook": { + "kernelName": "csharp" + } + }, + "source": [ + "使用NuGet包\n", + "===========" + ] + } + ], + "metadata": { + "kernelspec": { + "display_name": ".NET (C#)", + "language": "C#", + "name": ".net-csharp" + }, + "polyglot_notebook": { + "kernelInfo": { + "defaultKernelName": "csharp", + "items": [ + { + "aliases": [], + "languageName": "csharp", + "name": "csharp" + } + ] + } + } + }, + "nbformat": 4, + "nbformat_minor": 5 +} diff --git a/Docs/多语言笔记.100.1.测试.ipynb b/Docs/多语言笔记.100.1.测试.ipynb index bf00c75..00c4b74 100644 --- a/Docs/多语言笔记.100.1.测试.ipynb +++ b/Docs/多语言笔记.100.1.测试.ipynb @@ -27,16 +27,102 @@ "kernelName": "csharp" } }, - "outputs": [], + "outputs": [ + { + "data": { + "text/html": [ + "
