如何在javascript中实现区域/代码崩溃 [英] how to implement regions/code collapse in javascript

问题描述

如何在Visual Studio中实现JavaScript代码崩溃的区域？

How can you implement regions a.k.a. code collapse for JavaScript in Visual Studio?

如果javascript中有数百行，使用代码折叠会更容易理解与vb / C＃中的区域。

If there are hundreds of lines in javascript, it'll be more understandable using code folding with regions as in vb/C#.

#region My Code

#endregion

推荐答案

博客条目在这里解释了它和这个 MSDN问题。

你必须使用Visual Studio 2003/2005 / 2008宏。

Copy + Paste from Blog entry for fidelity sake:

1. 打开Macro Explorer


2. 创建新宏


3. 将其命名为 OutlineRegions


4. 点击编辑宏并粘贴以下VB代码：

1. Open Macro Explorer
2. Create a New Macro
3. Name it OutlineRegions
4. Click Edit macro and paste the following VB code:

Option Strict Off
Option Explicit Off

Imports System
Imports EnvDTE
Imports EnvDTE80
Imports System.Diagnostics
Imports System.Collections

Public Module JsMacros

    Sub OutlineRegions()
        Dim selection As EnvDTE.TextSelection = DTE.ActiveDocument.Selection

        Const REGION_START As String = "//#region"
        Const REGION_END As String = "//#endregion"

        selection.SelectAll()
        Dim text As String = selection.Text
        selection.StartOfDocument(True)

        Dim startIndex As Integer
        Dim endIndex As Integer
        Dim lastIndex As Integer = 0
        Dim startRegions As Stack = New Stack()

        Do
            startIndex = text.IndexOf(REGION_START, lastIndex)
            endIndex = text.IndexOf(REGION_END, lastIndex)

            If startIndex = -1 AndAlso endIndex = -1 Then
                Exit Do
            End If

            If startIndex <> -1 AndAlso startIndex < endIndex Then
                startRegions.Push(startIndex)
                lastIndex = startIndex + 1
            Else
                ' Outline region ...
                selection.MoveToLineAndOffset(CalcLineNumber(text, CInt(startRegions.Pop())), 1)
                selection.MoveToLineAndOffset(CalcLineNumber(text, endIndex) + 1, 1, True)
                selection.OutlineSection()

                lastIndex = endIndex + 1
            End If
        Loop

        selection.StartOfDocument()
    End Sub

    Private Function CalcLineNumber(ByVal text As String, ByVal index As Integer)
        Dim lineNumber As Integer = 1
        Dim i As Integer = 0

        While i < index
            If text.Chars(i) = vbCr Then
                lineNumber += 1
                i += 1
            End If

            i += 1
        End While

        Return lineNumber
    End Function

End Module

1. 保存宏并关闭编辑器


2. 现在让我们为宏分配快捷方式。转到工具 - >选项 - >环境 - >键盘，然后在显示命令包含文本框


3. 中搜索宏，现在在按快捷键下的文本框中输入所需的捷径。我使用Ctrl + M + E。我不知道为什么 - 我刚刚进入它并立即使用它：）
