TypeScript switch case
Summary: in this tutorial, you 如何使用发明者量化交易平台扩展API实现TradingView报警信号交易 will about the TypeScript switch. case statement.
Introduction to TypeScript switch case statement
The following shows the syntax of the switch. case statement:
First, the switch. case statement evaluates the expression .
Then, it searches for the 如何使用发明者量化交易平台扩展API实现TradingView报警信号交易 first case clause whose expression evaluates to the 如何使用发明者量化交易平台扩展API实现TradingView报警信号交易 same value as the value ( value1 , value2 , … valueN ).如何使用发明者量化交易平台扩展API实现TradingView报警信号交易
The switch. case statement will execute the statement in the first case clause whose value matches.
If no matching case clause is found, the switch. case statement looks for the optional default clause. If the default clause is available, it executes the statement 如何使用发明者量化交易平台扩展API实现TradingView报警信号交易 in the default clause.
The break statement that associates with each case clause ensures that the control breaks out of the switch. case statement once the statements in the case clause complete.
If the matching case clause doesn’t have the break statement, the program execution continues at the next statement in the switch. case statement.
By convention, the default clause is the last clause in the switch. case statement. However, it doesn’t need to be so.
TypeScript switch case statement examples
Let’s take some examples of using the switch…case statement.
1) A simple TypeScript switch case example
The following example shows a simple switch. case example that shows a message based on the target Id:
In this example, the targetId is set to btnDelete .
The switch. case statement compares the targetId with a list of values. Because the targetId matches 如何使用发明者量化交易平台扩展API实现TradingView报警信号交易 the 'btnDelete' the statement in the corresponding case clause executes.
2) Grouping case example
If you have a 如何使用发明者量化交易平台扩展API实现TradingView报警信号交易 code that is shared by multiple cases, you can group them. For example:
This example returns the days of a specific month and year.
If the month is 1,3, 5, 7, 8, 12, the number of days is 31. If the month is 4, 6, 9, or 11, the number of days is 30.
If the month is 2 and the year is a leap year, it returns 如何使用发明者量化交易平台扩展API实现TradingView报警信号交易 29 days, otherwise, it returns 28 days.
