Made a start but hit a brick wall

[Wormopolis]

its doing that because suvRandom isnt a url to an image

[Boy_Wonder]

Right so how would I get the url to the image -sorry really slow at this-

Thanks, I appreciate the explanation. Interesting way to go about it with the cosine, I probably wouldn't have even thought about using that.

look above for what I wrote about getting the URL from the array.  I can either type this all out for you or help you learn, and I have a feeling you really want to learn this stuff.

I should probably throw something in there to ensure it never gets too close to 0.. but no one has complained about its pseudo-randomness so far...

Which post exactly as there was two points

autoform is already an array when you use it as a variable in the javascript. each field in the autoform becomes a property of the auto form

so if your autoform was called

survival_images

and in the autoform you had a field

title

and

url


then in the javascript you would access a specific entry in the autoform with


plugin.settings...all your plugin name stuff...survival_images[N].title

or

plugin.settings...all your plugin name stuff...survival_images[N].url


where N is the number returned by the random result.

or

Oh! I need to add ; to the end of javascript lines that aren't commented don't I? and this is what I have so far

//Variable that contains the images here from autoform var suvImg=proboards.plugin.get('survival_images').settings.image_testing; //math.random randomizes images and will be used here var suvRandom=Math.floor((Math.random()*suvImg.length)); //Append image to div $('div#survivalImg').append($('<img src=" output here " />'));

Does this all look okay and how would I then put the output as an image? Would it be just calling the suvRandom or?

suvRandom becomes the integer you use to access the specific suvImage array element


and in that append, you have to break out of the single quotes if you want to use variables.  you cant use variables inside

'<img src="' + javascript stuff + '">'

Or would it be something like this

$('div#survivalImg').append($('<img src="'+ proboards.plugin.get('survival_images').settings.image_testing.image_url_test+'" />'));

with some way to get the number from the randomisastion done earlier? -trying to work it out at least let me know if I'm warmer or cooler at least-

[Wormopolis]

the first one is closer. putting the insert back into the append line defeats the purpose of putting it into a variable in the first place

[Boy_Wonder]

okay so I would still need to use the suvRand variable

-right- so the suvRand variable gives the random number but its not linked to an image url that's the current problem I'm trying to solve right? -just checking I'm on the right page-

[Wormopolis]

suvRand is just an integer.
suvImg is the array

suvImg[suvRand].url is the url to the image

[Boy_Wonder]

Okay and I knew I'd seen something like that somewhere to do with random numbers before -shoots self in foot- just without the .url.

[Boy_Wonder]

Okay editing to add that it's now giving an undefined url - suvRandom gives a random number output between 1 - 3
suvImg lists 4 objects to choose from, and trying to bugfix myself isn't working and I can't find the theory or anything behind to try and understand how it should be talking to each other

[Wormopolis]

let me see what you have so far

[Boy_Wonder]

Managed to fix it after sleeping and too much doctor pepper xD
