[英]RegEx - JavaScript - match word and not match another word
I use regex to match any string contains certain word (eg: 'dark') 我使用正则表达式匹配包含特定单词的任何字符串(例如:“ dark”)
if (features[i].attributes.color.match(new RegExp(dark, "ig")) ) )
..
..
How can I modify it to match any string contains 'dark; 如何修改它以匹配任何包含'dark;的字符串? but NOT contains 'blue' ?
但不包含“蓝色”? I tried:
我试过了:
if(
features[i].attributes.color.match(new RegExp(dark, "ig")) ) && !features[i].attributes.color.match(new RegExp(blue, "ig")) )
}
..
..
with no luck 没有运气
尝试将此正则表达式表示为“包含深色而不是蓝色”:
/^(?!.*\bblue\b)(?=.*\bdark\b).*$/
if(features[i].attributes.color.indexOf("dark") != -1 && features[i].attributes.color.indexOf("blue") == -1){
// found dark, didn't find blue
}
Use as following: 用途如下:
new RegExp(/dark/)
U can use 你可以用
.indexOf("dark")
If you use jquery then 如果您使用jQuery
.contains("dark")
