JavaScript,数组合并两个数组 - concat()
源代码: <!DOCTYPE html><html><body><p id="demo">点击按钮合并数组。</p><button onclick="myFunction()">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><p id="demo">Click the button to sort the array.</p><button onclick="myFunction()">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><p id="demo">Click the button to sort the array.</p><button onclick="myFunction()">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:
数字排序（按数字顺序降序）- sort()
源代码: <!DOCTYPE html><html><body><p id="demo">Click the button to sort the array.</p><button onclick="myFunction()">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:
将一个数组中的元素的顺序反转排序 - reverse()
源代码: <!DOCTYPE html><html><body><p id="demo">Click the button to reverse the order of the elements in the array.</p><button onclick="myFunction()">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
