可變內部模式

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" 

並且由於我的想法...我如何在表達式中獲得我的seperator？

在此先感謝！

Answer 1

您需要創建新的RegExp對象

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