如题，实践如下程序
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="format-detection" content="telephone=no,email=no,adress=no">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no">
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black">
<title>Title</title>
</head>
<body>
<script>
window.onload=()=>{
let arr = ["a","b","c","d","e","f","g"];
const breakFn = ()=>{
for(let i=0;i<arr.length;i++){
if(arr[i]==="d"){
break;
}
console.log(arr[i]);
}
console.log("我是breakFn for后面的")
};
const continueFn = ()=>{
for(let i=0;i<arr.length;i++){
if(arr[i]==="d"){
continue;
}
console.log(arr[i]);
}
console.log("我是continueFn for后面的")
};
const returnFn = ()=>{
for(let i=0;i<arr.length;i++){
if(arr[i]==="d"){
return false;
}
console.log(arr[i]);
}
console.log("我是returnFn for后面的")
};
breakFn();
console.log("===============");
continueFn();
console.log("===============");
returnFn();
};
</script>
</body>
</html>
运行结果：
break：打断并跳出当前循环。
continue:仅跳出当次循环。
return false:打断当前方法并返回值
javascript中，break，continue和return false的用法
