如何使用javascript查找匹配的文本

Question

如何使用正则表达式提取“text：”后面的单词？输入类似于：

some string some string (text:the_word_i_want_to_get some string) some string
some string some string (text:next_word_i_want_to_get some string) some string

，输出应为：

["the_word_i_want_to_get", "next_word_i_want_to_get"]

Answer 1

您可以匹配第一个出现的单词，如下所示：

var input = "some string...",// Assume this is what you wrote in your question.
    match = input.match(/text:(\w+)/)[1];

要获得所有匹配项，您可以将其置于循环中：

while (/text:(\w+)/) {
  matches.push(input.match(/text:(\w+)/)[1]);
  input = input.replace(/text:(\w+)/, "");
}
