Javascript正则表达式可以匹配两个字符串之间的子字符串，但是子字符串可以包含DOT（。）

Question

I do want to match all subbstrings which are between {{ and }}

When this substring does not contain . , the regex works fine :

"When he come, {{person}} will give his son {{something}}".match(/{{(\w*)}}/g) ; 

Result :

["{{person}}", "{{something}}"]

Now , if this substring contains . (dot) , the regex does not work as it is expected :

"When he come, {{person.firstname}} will give his son {{something}}".match(/{{(\w*)}}/g) ;

Result :

["{{something}}"]

How to change the regex to be able to mach also substrings contains DOT , for example here : person.firstname . ?

Answer 1

or use this pattern to match anything between {{ and }}

{{([^}]*)}}

explanation:

[^}] a character class, anything but "}"

Answer 2

\\w will only match az, AZ, 0-9, _ , cf. http://www.w3schools.com/jsref/jsref_regexp_wordchar.asp .

Use this regular expression to include an arbitrary number of points as well:

/{{([\w\.]*)}}/g
