// 两行字符串分别写在两行上: `the newline character at the end of this line is included literally in this string` 请注意,当使用单引号界定字符串时,必须小心处理英语缩写和所有格,例如can’t和O’Reilly’s。由于撇号与单引号字符相同,必须使用反斜杠字符(\)来“转义”出现在单引号字符串中的任何撇...
将字符串分割成多个子字符串 为了区分一个字符串转换为一个子字符串数组,你可以使用的split()方法: 1varmyString = "coming,apart,at,the,commas";2varsubstringArray = myString.split(",");//["coming", "apart", "at", "the", "commas"]3vararrayLimited = myString.split(",", 3);//["comin...
在没有引用任何JS的前提下，也没有在window.onload中，如何不在函数中的情况下，中断JS代码执行？例如：
Let’s look at the syntax for the JavaScript string split() method: var new_list = text.split(character, limit); The split() method is added to the end of our “text” variable. Our text variable is split based on the separator character we specify. We assign the result of the split...
5. at() ES5 对字符串对象提供charAt方法,返回字符串给定位置的字符。该方法不能识别码点大于0xFFFF的字符。 6. normalize() 许多欧洲语言有语调符号和重音符号。为了表示它们,Unicode 提供了两种方法。一种是直接提供带重音符号的字符,比如Ǒ(\u01D1)。另一种是提供合成符号(combining character),即原字符与重...

另一个有用的资源是 Mathias Bynens 的博文:“JavaScript’s Internal Character Encoding: UCS-2 or UTF-16?”。 charCodeAt()方法可以查看指定码元的字符编码,传入的参数值从零开始,其值将被转换为整数(undefined 被转换为 0),如果参数值超出了 0 到 str.length - 1 的范围NAN,传入的参数值介于 0 和 6553...
