模式内的变量[重复]

Question

var seperator = ',', group = 'red, blue';
//group.search(seperator/g) - g is not defined
group.search(/seperator/g) // looks for "seperator"
group.search('/' + seperator + '/g') // doesn't seem to find my "seperator"

我没有想法......我如何在表达中获得我的seperator？

提前致谢！

Answer 1

你需要创建新的正则表达式对象

var test = new RegExp(seperator, 'g');
group.search(test)
