JavaScript之数组冒泡排序

1.数组元素的拼接

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>数组元素的拼接</title>
</head>
<body>
    
</body>
</html>
<script type="text/javascript">
    //concat:拼接
    var arr1 = ["一念愚即般若绝"];
    var arr2 = ["一念智即般若生"];
    var arr = arr1.concat(arr2);
    console.log(arr);
</script>

2.数组元素转换为字符串

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>数组转换为字符串</title>
</head>
<body>
    
</body>
</html>
<script type="text/javascript">
    var arr = ["为道法祖仰云际三台鼎峙","玄之又玄","先天地生溯阁中万古灯传","极本无极"];
    //join:数组转换为字符串,默认是逗号,join中可添加区分方式
    var arrs = arr.join("-");
    console.log(arrs);
</script>

3.数组冒泡排序

　　sort:排序字符串和数字

 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>数组排序</title>
</head>
<body>
    
</body>
</html>
<script type="text/javascript">
    //sort:字符串排序和数字排序
    var arr = ["ac","ad","aa"];
    arr.sort();
    console.log(arr);

    var arr1 = [1,10,115,16];
    arr1.sort();
    //比较数字和比较字符串一样,逐个比较
    console.log(arr1);
</script>

 

 sort的冒泡排序写法

 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>数组排序</title>
</head>
<body>
    
</body>
</html>
<script type="text/javascript">
    //sort的冒泡排序写法
    //通过a与b的大小
    //等于0 大于0 小于0
    //区分是升序排序还是降序排序
    var arr2 = [1,12,15,123];
    arr2.sort(function (a,b){
        return a-b;
    });
    console.log(arr2);
</script>
