javascript - passing a function within itself -

-

I have a javascript function called "update data" which I use in another function "process" as a parameter I am passing the function "updateData" itself. 

  var updateData = function () {var bean = {"name": $ ("# name"). Val (), "sort": $ ('#sort'). Val (), "Reference": "Sample"}; Var Param = {'Bean': Been, 'Reference': "Sample", 'Ajtext': 'POST', 'url': 'samp.json', 'valFn': Valid data, 'updateFn': UpdateData, 'Populaphane ': PopulateData}; Process (ultimate); };

I am doing this because I need to force "updateData" to create a button in the process ()

Does this cause any problem Will happen? Is it true?

(I have not encountered any problems so far, but I'm new to functional programming, and I want to make sure that there is no problem doing so.)

This will work because the reason for doing this is that this function is only set to write this function And it has not been evaluated. Therefore, when you call this function, in the updateData variable, the reference object is already referenced and that reference will be passed to the object that you have defined within .

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
