Help choosing more than one item from an array

[sdetweil]

ok, your source ‘lifeFormArray’ is a hash… good for looking up randomly

now to get the user specified list into something usable, split is the way as already posted

// if user specified something
if(this.config.lifeForms.length >0 )
{
     // split will return an array with only one entry if no comma found
     this.config.user_keys=this.config.lifeForms.split(',');
}
else
     // add an entry to a special lifeFormArray entry for missing config info
     this.config.user_keys.push("none");

now, you want random, or walk the array of user_keys?

function getRandomInt(max) {
  return Math.floor(Math.random() * Math.floor(max));
} 

// get one of the user specified data keys, using random
var key=this.config.user_keys[this.getRandomInt(this.config.user_keys.length)];

// append that id value to the url.
this.url = "http://eol.org/api/pages/1.0.json?batch=false&id=" +this.lifeFormArray.key;

its unclear if u wanted all or just one…

@sdetweil

Random would be great!

I’ll give it a try, Thanks!

[sdetweil]

@justjim1220 make sure to add an entry to the lifeFormArray that matches the string you define for ‘none’ (no user entry supplied)

[justjim1220]

@sdetweil

So, would the entry be like this: “Cats”, “Bats”, “Bears”,

or like This: “Cats,Bats,Bears”,

?

Well, at the moment it is throwing the following error:

I’ll look at it some more here in a little bit…

Thanks for your input!

Jim, as it seems you’ve taken over this topic, I will leave it to you.

I don’t know about taking it over, LOL.
Just trying to help!

@strawberry-3-141 said in Help choosing more than one item from an array:

what you describe above is actually not an array, it’s an object (hash). Arrays are always defined with [] not {}.

Object. Array. What’s the difference? (That’s a joke. Laugh) :-D

@justjim1220 that error looks like from the constructed url failing

[sdetweil]

@justjim1220 the second. Don’t depend on users to do multiple entries
