大家好, 任何人都可以为下面提到的场景提供JavaScript功能或Regexp。 例如:我的字符串是: 1)' My String abc-s '。 我有一些项目来匹配上面字符串中的单词。
var items = [abc,def,ghi];如果上面的字符串包含任何数组项,那么它必须返回true。 在上面的项目数组中不包含'abc',所以它必须返回false。 2)
var items = [abc-s,def -s,ghi-s];如果上面的字符串包含上述任何项目,则必须返回true。 / pre> 我尝试过: 大家好, 任何人都可以为下面提到的场景提供JavaScript函数或Regexp。 例如:我的字符串是: 1)' My String abc-s '。 我有一系列与上述字符串中的单词匹配的项目。 < pre> var items = [abc,def,ghi];

解决方案
\b - 表示单词的开头或结尾,因此您可以创建如下表达式 (\babc \b | \ bdef \b | \ bhgi \ b) 您可以在 Scriptular - Javascript Regular Expression Editor [ ^ ]
查看此内容: // var str =My String abc; var str =My String abc-s; var items = [abc,def,ghi]; // var items = [abc-s,def-s,ghi-s]; for(i = 0; i< items.length; i ++){ var pattern = new RegExp((< = \\\\ | \\ b) )+ items [i] +(?= [] \\b | \\ | |
)); alert(pattern.test(str)); }

Hi Everyone, Can any one please provide a JavaScript function or Regexp for the below mentioned scenario. For Example: my string is : 1) 'My String abc-s'. I have array of items to match the word in the above string.
var items= ["abc", "def", "ghi"];If the above string contains any of the array item then it has to return true. In the above array of items not contain 'abc', so it has to return false. 2)
var items= ["abc-s", "def-s", "ghi-s"];If the above string contains any of the above item then it has to return true.

var items= ["abc-s", "def-s", "ghi-s"];If the above string contains any of the above item then it has to return true. 解决方案 \b - indicates beginning or end of word, so you could create expression like below (\babc\b|\bdef\b|\bhgi\b) you could try it online at Scriptular - Javascript Regular Expression Editor[^]Check this out: //var str = "My String abc"; var str = "My String abc-s"; var items= ["abc", "def", "ghi"]; //var items = ["abc-s", "def-s", "ghi-s"]; for (i=0; i < items.length; i++){ var pattern = new RegExp("(<=\\s|\\b)"+ items[i] +"(?=[]\\b|\\s|)"); alert(pattern.test(str)); }
