摘要:合并两个数组-concat()源代码:"demo">点击按钮合并数组。​点我​functionmyFunction(...

合并两个数组 - concat()

源代码:

<!DOCTYPE html> <html> <body> "demo">点击按钮合并数组。</p> ​ <button>点我</button> ​ <script> function myFunction() { var hege = ["Cecilie", "Lone"]; var stale = ["Emil", "Tobias", "Linus"]; var children = hege.concat(stale); var x=document.getElementById("demo"); x.innerHTML=children; } </script> ​ </body> </html>

测试结果:

Cecilie,Lone,Emil,Tobias,Linus

合并三个数组 - concat()

源代码:

<!DOCTYPE html> <html> <body> <script> var parents = ["Jani", "Tove"]; var brothers = ["Stale", "Kai Jim", "Borge"]; var children = ["Cecilie", "Lone"]; var family = parents.concat(brothers, children); document.write(family); </script> </body> </html>

测试结果:

Jani,Tove,Stale,Kai Jim,Borge,Cecilie,Lone

数组排序(按字母顺序升序)- sort()

源代码:

<!DOCTYPE html> <html> <body> "demo">Click the button to sort the array.</p> ​ <button>Try it</button> ​ <script> function myFunction() { var fruits = ["Banana", "Orange", "Apple", "Mango"]; fruits.sort(); var x=document.getElementById("demo"); x.innerHTML=fruits; } </script> ​ </body> </html>

测试结果:

Apple,Banana,Mango,Orange

数字排序(按数字顺序升序)- sort()

源代码:

<!DOCTYPE html> <html> <body> "demo">Click the button to sort the array.</p> ​ <button>Try it</button> ​ <script> function myFunction() { var points = [40,100,1,5,25,10]; points.sort(function(a,b){return a-b}); var x=document.getElementById("demo"); x.innerHTML=points; } </script> ​ </body> </html>

测试结果:

1,5,10,25,40,100

数字排序(按数字顺序降序)- sort()

源代码:

<!DOCTYPE html> <html> <body> "demo">Click the button to sort the array.</p> ​ <button>Try it</button> ​ <script> function myFunction() { var points = [40,100,1,5,25,10]; points.sort(function(a,b){return b-a}); var x=document.getElementById("demo"); x.innerHTML=points; } </script> ​ </body> </html>

测试结果:

100,40,25,10,5,1

将一个数组中的元素的顺序反转排序 - reverse()

源代码:

<!DOCTYPE html> <html> <body> "demo">Click the button to reverse the order of the elements in the array.</p> ​ <button>Try it</button> ​ <script> var fruits = ["Banana", "Orange", "Apple", "Mango"]; ​ function myFunction() { fruits.reverse(); var x=document.getElementById("demo"); x.innerHTML=fruits; } </script> ​ </body> </html>

测试结果:

Mango,Apple,Orange,Banana
