正则表达式从某个字符开始提取字符串而不包含该字符本身

Question

Suppose I have the following js code:

r='d|daa|dd';  
reg = /\|.*/;  
result = reg.exec(r);

This will return |daa|dd , but what I want is daa|dd .

What should the regex be? Thanks

Answer 1

Grouping is the way to go:

reg = /\|(.*)/;

It will search for string starting with |, but will capture the group (enclosed in brackets) separately for further use.

Answer 2

r='d|daa|dd';
reg = /\|(.*)/;
result = reg.exec(r);

result[1] is then populated with what's in the capture group.
