backbone.js - Collection change event on an attribute which is a model itself -

-

I have created a backbone. (Say) Select ModelA and I model a special feature of those people. It is straightforward, ... but ('change: attr1'). This phenomenon is removed at the right time when this is needed, the problem occurs when this feature is another model (model B), which has its own characteristics, if one feature of Modelbie has changed, then the collection is on that event Will not be able to capture (and it is true, the model's attribute has never been changed, "attributes have changed properties").

One idea is from model-B to the model A's wire-up listener and then in the collection. It can work, but we are now adding many listeners to create this series of events. I also suspect that when we do not need them, those listeners will have a pain to open them.

Is there a better way (or alternative) way to do this? Any feedback is appreciated.

Thank you

I think the clear way forward is through the Guardian model See incidents from my example:

But you can override collection methods _addReference and _removeReference to add custom event binding logic.

Hope this helps

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
