怎么将字符串按大写字母分隔成字符串数组

写道 怎么将字符串按大写字母分隔成字符串数组 例如:createTechBook 转化成 array(create,Tech,Book)或者 create-Tech-Book JS: array: alert("createTechBook".split(/(?=[A-Z])/)) string: "createTechBook".replace( /([A-Z])/g, '-$1') PHP: array: preg_split("/(?=[A-Z])/", "createTechBook"); string: preg_replace("/([A-Z])/","_\\1","createTechBook"); preg_replace("/(?=[A-Z])/","-\\1",'createTechBook') //效率高 感谢 Nutz喜洋洋 alzui:alz 天凡 阿旭 T 等等大哥们的帮助!!!!
