varregex =/,/;varstring="html,css,javascript";console.log(string.split(regex) );// => ["html", "css", "javascript"] 又比如,如下的日期格式: 2017/06/26 2017.06.26 2017-06-26 可以使用split“切出”年月日: var regex =/\D/; console.log
// 字符串分割成数组strArr,以换行符分隔 let strArr = str.split('\n'); // 定义正则表达式,表达式有挺多表示方法的,下面几个注释掉的作用是一样的 // let regex = /\/\/\s.*/g; // let regex = new RegExp("// .*","g"); // let regex = new RegExp(/\/\/\s.*/,"g"); let...
split("."))[0]); n = parseInt(n,10); // 下面做法更简便高效,用位运算来做(右移0位,或者两次取反),且非数值型的值会转成0 alert(5>>0); alert(~~5); // 值为 5 alert(5.55>>0); alert(~~5.55); // 值为 5 alert(-98.4>>0); alert(~~-98.4); // 值为 -98 alert('absd'...
console.log(string.match(regex)[0]); // => id="container" 当然,这样也会有个问题。效率比较低,因为其匹配原理会涉及到“回溯”这个概念(这里也只是顺便提一下,第四章会详细说明)。可以优化如下: var regex = /id="[^"]*"/var string = ''; console.log(string.match(regex)[0]); // => id...
String.prototype.split()作用：将一个字符串按照分割器进行分割，将分割后的字符串片段组成一个新的数组，其中分割器separator可以是一个字符串或者一个正则表达式。代码示例：const str = 'hello, world!';console.log(str.split('')); // ["h", "e", "l", "l", "o", ",", " ", "w", "o...
