[英]regular expression for words beginning with a certain string (javascript)
I am trying to write a regular expression in javascript for finding if any words in a sentence start with a particular phrase. 我试图用javascript写一个正则表达式,以查找句子中是否有以特定短语开头的单词。 Eg, I'd like to know if "by" is contained at the beginning of any word in the following sentence : "The Tipping Point by Malcolm Gladwell".
例如,我想知道“ by”是否包含在以下句子的任何单词的开头:“ Malcolm Gladwell的引爆点”。
I tried using \\b
but /\\bsor/
will match a sentence like 'Mary's organ is broken.' 我尝试使用
\\b
但/\\bsor/
将匹配“玛丽的器官坏了”这样的句子。 ie it treats punctuation as a word boundary and starts matching after them. 即,它将标点符号视为单词边界,并在它们之后开始匹配。 Any thoughts?
有什么想法吗?
/(?:\\s|^)bar/ -- perhaps -- although see the answer for splitting it first /(?:\\ s | ^)bar / -也许-尽管请先参阅拆分的答案
/(?:\s|^)bar/.test("bar") // true
/(?:\s|^)bar/.test("foo bar") // true
/(?:\s|^)bar/.test("foo'bar") // false
/(?:\s|^)bar/.test("Sentence One.bar Two.") // false ... "oops"?
On Regexpedia, there is an article has the code and explainations. 在Regexpedia上,有一篇文章提供了代码和说明。
