有两种特殊的语句可以在循环中使用: break 和 continue。 ———– Break break 命令用来打断整个循环, 并继续执行循环后面的代码(如果有的话)。 例子 var i=0 for (i=0;i<=10;i++) { if (i==3){break} document.write(“The number is ” + i) document.write(“”) } 结果 The num...
if(i ===3) {break; } text +="The number is "+ i +""; } Try it Yourself » In the example above, thebreakstatement ends the loop ("breaks" the loop) when the loop counter (i) is 3. The Continue Statement Thecontinuestatement breaks one iteration (in the loop), if a specif...
for (i = 1; i<=10; i++) { if (i > 5) { break; } document.write(i + ""); } 运行结果: code 1 2 3 4 5 JavaScript continue 跳过当前循环 与break 命令不同的是,JavaScript continue 跳过当前的循环(相当于本次循环无效)而继续下次循环,直到循环结束。 下面的例子演示了输出 1-10 之间...
新 js 引擎叫 SpiderMonkey。js 语言增加新特性,从更多语言那做了借鉴,比如 Python 和 Perl 的数组相关方法,Perl 对于字符串和正则的处理,Java 的 break / continue 标签语句以及 switch。语言升级为 JavaScript 1.2(特性详细介绍),和 SpiderMonkey 一起集成到 Netscape 4.0。ES3结合了 js 1.2 和 JScript 3.0,I18N...
Generally, as the code is executed, the event loop will eventually hit thepollphase where it will wait for an incoming connection, request, etc. However, if a callback has been scheduled withsetImmediate()and thepollphase becomes idle, it will end and continue to thecheckphase rather than ...

I was once a continue, break, return everywhere, kind of dude and felt very clever for leveraging those features, but really it doesn't help your team. The less bouncing around you have to do when reading code the better. continue makes code harder to read for other people -you might ...
The Jessieswitchstatement grammar requires that all cases be terminated by a terminating statement,return,break,continueorthrow, avoiding a perpetually annoying hazard of C-like languages. All control-flow branches, includingswitchcases, must be blocks, not naked statements, avoiding hazards and giving...
If you want to stop the loop while running, use the break command. For example:Copy while (true) { pwd = prompt("Enter password:", ""); if (pwd == "password") break; } This loop would endlessly ask for the password and it would end only when the user enters the word “...
