合并两个数组 - concat()
源代码:
<!DOCTYPE html> <html> <body> "demo">点击按钮合并数组。</p> "myFunction()">点我</button> "Cecilie", "Lone"]; var stale = ["Emil", "Tobias", "Linus"]; var children = hege.concat(stale); var x=document.getElementById("demo"); x.innerHTML=children; } </script> "htmlcode">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()

P70系列延期,华为新旗舰将在下月发布
3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。
而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?
根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
