create string from JSON values in jQuery

Question

I'd like to create a string of ISBNs from a JSON object to search multiple books in Google Books.

I can get the ISBNs by parsing Google Books' JSON with this path:

volumeInfo.industryIdentifiers[0].identifier

(Here I'm doing that to get a simple book list: jsfiddle.net/LyNfX )

How do I string together each value in order to get this query structure, where each ISBN is preceded by "isbn:", and after the first one they are separated by "OR"

https://www.google.com/search?btnG=Search+Books&tbm=bks&q=Springfield+isbn:1416549838+OR+isbn:068482535X+OR+isbn:0805093079+OR+isbn:0306810328

see the fiddle. It successfully lists the info for each book. what I was looking for was creating a string from that same info. — nathanbweb

Starting from an array of ISBN strings called list:

list.map(function(v){return "isbn:"+v;}).join("+OR+")

As for building your list of ISBN's which I understand to be the identifier prop in your industryIdentifiers (if industryIdentifier is a bona fide Array):

var list = [];
volumeInfo.industryIdentifiers.forEach(function(e,i){list.push(e.identifier);});

You could also just build the final string in one fell swoop and not build an array at all, but this means extra logic to prevent inserting an extra delimiter (+OR+ being the delimiter)

var output = "";
volumeInfo.industryIdentifiers.forEach(function(e,i){output += "isbn:"+e.identifier+"+OR+";});
output.slice(0,-4); // clear out last +OR+

great. how would I get the volumeInfo.industryIdentifiers.identifier 's into the array to start?

I don't know what the format of that is. Could you post it or something?

nathanbweb Over a year ago

in my fiddle [jsfiddle.net/LyNfX] , I use the jQuery template plugin to create html for each book like this: var mylist = "{{each items}}" + "<div class=book id=" + theid + ">" + "<p><b>title</b> is ${volumeInfo.title}" + "<p><b>author</b> is ${volumeInfo.authors}" + "<p><b>isbn10</b> is ${volumeInfo.industryIdentifiers[0].identifier}" + "</div>{{/each}}";

so what I need now is to get each volumeInfo.industryIdentifiers.identifier into an array, rather than printing it into html. then I can do your list.map ... on that array -- if I'm understanding correctly?

on this related q, it looks like this was the approach -- is this on the right track? for(i=0;i<data.length;i++){ things[i]=[data[i].id,String(data[i].username),String(data[i].things)]; stackoverflow.com/questions/3442487/…

var arrayOfISBNs = [123,456,789...];
var result = "isbn:" + arrayOfISBNs.join(" OR isbn:")

Just use array join.
