Haskell chain functions based on separate conditions -

-

Is there an efficient / easy way when a panel is applied to a argument, then only those tasks apply Are the applications that meet their needs in order to be applied? Eg:

I have 1 argument 'Obj' and 3 functions: func1, func2, func3. Everyone needs their own needs, which can also result in logic. Like pseudo code: 

  (if condition1 then func1). (If condition2 again func2). (If condition 3 then fun 3) Obj

So if all the positions are eligible, then all 3 functions will be applicable in the ob.

Is there any way that I can do it properly

First, you have $ before obj . I feel that in answer to your question, you just else section: 

  (if c0 then f0 another id) $ (if C1 then F1 another ID ) $ (If C2 then F2 other ID) $ Eg

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
