jquery - How to select multiple options dynamically in chosen select -

-

I am selecting to choose Jquery on the HTML page where the user can choose multiple options and save the record. I need to present the update page to the user and I am trying to drop down selectively selected multi select items with archived options. The selected single selection can be done by triggering an update: 

  $ ('# ns_StatusClass'). Val (2); $ ('# Ns_StatusClass') Trigger ("Chosen: Update") ;.

But I am not able to understand how to be completed with the selected options selected. I tried to trigger the update after selecting such values: 

 for  (var i = 0; i & lt; $ PAGE.allStatus.length; i ++ ) {$ ('# Ns_StatusClass') Val ($ PAGE.allStatus [i] .id); //$ ('#ns_StatusClass').trigger("chosen:updated "); } $ ('# Ns_StatusClass') Trigger ("Selected: Updated");

But it only shows results with the last option in selecting the loop.

Is not it possible to set many options in the multiple select dropdowns?

Use this code to select several options: 

 < Code> (var i = 0; i & lt; $ PAGE.allStatus.length; i ++) {$ ('# ns_StatusClass option [value =' + $ page allstatus [i] .id + ']' ). Ether ("selected", "selected"); }

If there are one or more spaces, then use the double coat: 

 for  (var i = 0; i

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
