Make array from regex
提问by Adam
I have this string:
我有这个字符串：
{example1}{example2}{example3}
This is the regular expression to find these {anything in it}:
这是查找这些的正则表达式{anything in it}：
/\{.*?\}/g
Now I want to know how put them in an array so I can do a for instatement.
现在我想知道如何将它们放在一个数组中，以便我可以做一个for in声明。
I want an array something like array("{example1}","{example2}","{example3}");?
我想要一个类似的数组array("{example1}","{example2}","{example3}");？

your_array = string.match( pattern )
回答by alex
var matches = '{example1}{example2}{example3}'.match(/\{.*?\}/g);
// ['{example1}', '{example2}', '{example3}']
Also, you should probably use a forloop to iterate through the array. for incan have side effects, such as collecting more things to iterate through the prototype chain. You can use hasOwnProperty(), but a forloop is just that much easier.
此外，您可能应该使用for循环来遍历数组。for in可以有副作用，比如收集更多的东西来迭代原型链。您可以使用hasOwnProperty()，但for循环要容易得多。
For performance, you can also cache the lengthproperty prior to including it in the forcondition.
为了提高性能，您还可以在将length属性包含在for条件中之前缓存该属性。
