However, for readability, I'd recommend to use the native switch statement.One can always scratch the left ear passing its right hand through the back of the neck... (sorry for my english, I mean: "one can always complicate things as much as possible...in this case, avoiding the switch statement in favor of this complicated solution doesn't seem to be the right thing to do...)I'm truly amazed how this has gotten 34 up votes.

Examples might be simplified to improve reading and basic understanding. another code block: Ex: how does this relate to switch?

Stack Overflow works best with JavaScript enabled In terms of readability and maintainability, this is absolutely horrific.

Ein sauber formatierter Code sorgt dafür, dass die switch-Anweisung besser lesbar ist.Es gibt auch Fälle, in denen es Sinn macht, die break-Anweisung zu unterlassen, z.B. Let’s emphasize that the equality check is always strict. default 关键词. However, this is not always the best solution, espe Type matters.

In this example case 4 and 5 share the same code block, and 0 and 6 share This means that any case that evaluates to true will be a match.. Just like with else if, switch is evaluated from top to bottom, and the first true match will be accepted. your coworkers to find and share information.

Here is my own approach:The problem with the above approaches, is that you have to repeat the several Another way of doing multiple cases in switch statement, when inside a functionTo subscribe to this RSS feed, copy and paste this URL into your RSS reader.

@believesInSanta it's literally just normal case fallthrough with weird formatting (spaces instead of newlines)I definitely prefer this version. https://developer.mozilla.org/.../JavaScript/Reference/Statements/switch If multiple cases matches a case value, the first case is selected.

@AfshinMehrabani maybe it can be protected, not closed?Somehow it works for me in Chrome, in the javascript console: @Barney No, without the break you can fall through to the next case.
If no matching cases are found, the program continues to the default label. 4 @Barney No, without the break you can fall through to the next case. I need multiple cases in switch statement in JavaScript, Something like:How can I do that?

Examples of Case Statement in JavaScript are as follows: Example 1. var x = 1; switch (x) {case 0: console.log(“Zero”); break; case 1: Note that in this example, the cases share the same code block, and that the default case does not have to be the last case in a switch block (however, if default is NOT the last case in the switch block, remember to end it with a break). default 关键词规定不存在 case 匹配时所运行的代码：.

If there's no way to do something like that in JavaScript, I want to know an alternative solution that also follows In Javascript to assign multiple cases in a switch, we have to define Or for earlier versions of JavaScript, you can do this:Note that this won't work in older IE browsers, but you could patch things up fairly easily.

Therefore, even though our grade variable is 87 and therefore evaluates to true for C and D as well, the first match is B, which will be the output. However, this is not always the best solution, espe

The block breaks (ends) there anyway.If today is neither Saturday (6) nor Sunday (0), write a default message:

Consider a situation when we want to test a variable for hundred different values and based on the test we want to execute some task.

Switch case statements are good for evaluating fixed data types. Sometimes you will want different cases to use the same code, or fall-through to a common default. @Seiyira by definition, there is no next case after the last. The ability to “group” cases is a side-effect of how switch/case works without break.
