javascript - Use lodash to find a matching value if it exists -


i have following:

 myarray = [{         "urltag": "google",         "urltitle": "users",         "status": 6,         "nested": {             "id": 2,             "title": "http:\/\/www.google.com",         }     },     {         "urltag": "bing",         "tabtitle": "bingusers"     }]

i have myurltagtosearch = "yahoo", want loop through myarray, check if urltag equal "yahoo", if yes: return "yahoo", if not: return empty string (""). in example, should return "" because there "google" , "bing".

can lodash?

you can use lodash's find() method mixed regular conditional (if) statement this.

for starters, search array, can use:

var result = _.find(myarray, { "urltag": "yahoo" });

you can replace "yahoo" myurltagtosearch variable here.

if no matches found it'll return undefined, otherwise it'll return matching object. objects truthy values , undefined fasley value, can use result condition within if statement:

if (result)     return "yahoo"; else     return "";

we don't need define result here, can use:

if ( _.find(myarray, { "urltag": "yahoo" }) )     return "yahoo"; else     return "";

or even:

return _.find(myarray, { "urltag": "yahoo" }) ? "yahoo" : "";
