Basic knowledge of the switch clause in the basic Javascript tutorial

This article mainly introduces the switch statement related to the basic Javascript tutorial. For more information, see the format of the stwith statement below:

The Code is as follows:

Switch (expression ){
Case value: statement1
Break;
Case value2: statement2
Break;
....
Case value: statement
Break;
Default: statement;

If expression is equal to case, statament is executed.

Keyword break: the code jumps out of the switch.

If there is no keyword break, the Code continues to execute the next situation. Keyword default is the result of execution when the value of all expressions is not equal to the value.

The Code is as follows:

Iwork = parseInt (prompt ("enter a value from 1 to 5 "));
Switch (iwork ){
Case 1: document. write ("Monday ")
Break;
Case 2: "Week 2"
Break;
Case 3: "week 3"
Break;
Case 4: "Week 4"
Break;
Case 5: "day of the week"
Break;
Default: "enter a reasonable value ";
