javascript - Using regex with jQuery

Question

How can I do something similar to the below

result = $.grep(data, function(e){ return e.firstname == name; });

with having name to be a regex expression, i.e. name starts with "Kevin*"

Answer 1

如果没有测试，我建议：

result = $.grep(data, function(e){
             return new RegExp('^Kevin').test(e.firstName);
         });

要使用变量，则可以将上面的内容重写为：

var name = 'Kevin';
result = $.grep(data, function(e){
             return new RegExp('^' + name).test(e.firstName);
         });

参考：

• JavaScript 正则表达式。
• RegExp.test().
