javascript - Insert object into multidimensional array in Meteor MongoDB -

-

I am learning the meteor and I find it difficult to understand MongoDB. I have a collection that has been named as the menu: 

 id: 123, cat: 'beginning', description: {[item: 'nachos', value: '3.99', desc: 'chips & queso']}

I I want to add another item to that collection: 

 id: 123, cat: 'starters', Description: {[Item:' nachos', price: '3.99', desc: 'chips and My code looks like this: / P> 
 , which looks like this: ['item:' '4.99', 'descended' Enukaprsrt (_ {id: '123'}, {$ Push: {Description: [[before 'Kailami'}, {value: '4.99'}, {desc: 'fried calamari'}]}});  
 
 I also tried to use "update" but I get an error for "non-array $ Push Modfire can not be applied" error 
 
  UPDATE  Thank you Sindis, you were right and I was able to do this job. 
 
 I have created a new collection named Menu 2 in this way. 
 
  54, cat: 'Beginner, Description: [[Item:' Nacho 'Price:' 3.99 '}]

Then "Update" has been suggested: / P> 

  Menu 2.Update ({id: '54 '}, {$ push: {Details: {item:' kelami ', value:' 4.99 '}}});

And I got it! 

 id: 54, cat: 'beginning', description: [[item: 'nachos', value:' 3.99 '}, {item:' kalami ', value:' 2. 99}}

Not tested but I think it should look more like this: 

  Menu.upsert ({_ id: '123'}, {$ push: {details: {item: 'calamari', price: '4.99', desc: fried calamari '} }});

Different sections of the object are not required to push you around the object and the update / upstream is already hoping to move the object to an array So there is no need for square brackets.

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
