So the goal is to get a string like this:
somesite.com/-%20Luzon%20-/Bicol%20Region/Albay/Busay%20Falls/Busay_falls_10.jpg
So I started to build the object-array multi-dimensional thing and I'm not sure how you'd build the url using the name of the array groups.
var photoArray = {},
islandGroups = ["- Luzon -", " - Visayas -", "-Mindanao-"],
luzonRegions = ["Bicol Region", "Cagayan Valley", "Calabarzon", "CAR", "Central Luzon", "Ilocos Region", "Mimaropa"],
bicolProvinces = ["Albay", "Camarines Norte", "Camarines Sur", "Catanduanes", "Masbate", "Sorsogon"],
albayProvinceTravelDestinations = ["Busay Falls", "Hoyop-Hoyopan Cave", "Lignon Hill", "Malabsay Falls", "Mt Mayon", "Panicuason Hot Spring Resort", "Vera Falls"];
busayFallsPhotoPattern = ["Cover, Busay_falls_"];
busayFallsPhotoPatternID1 = [""];
busayFallsPhotoPatternID2 = ["1", "1_2", "10", "2", "2_2", "3", "3_2", "4", "4_2", "6", "7", "8", "9"];
baseURL = "somesite.com";
/* build sub-array */
var islandGroupsArrayLength = islandGroups.length;
for (var i = 0; i < islandGroupsArrayLength; i++) {
photoArray[islandGroups[i]] = {};
}
var luzonRegionsLength = luzonRegions.length;
for (var i = 0; i < luzonRegionsLength; i++) {
photoArray["- Luzon -"][luzonRegions[i]] = {};
}
var bicolProvincesLength = bicolProvinces.length;
for (var i = 0; i < bicolProvincesLength; i++) {
photoArray["- Luzon -"]["Bicol Region"][bicolProvinces[i]] = {};
}
var albayProvinceTravelDestinationsLength = albayProvinceTravelDestinations.length;
for (var i = 0; i < albayProvinceTravelDestinations; i++) {
photoArray["- Luzon -"]["Bicol Region"]["Albay"][i] = {};
}
/* build string before converting space to %20% */
/*
busayFallsPhotoPattern = ["Cover, Busay_falls_"];
busayFallsPhotoPatternID1 = [""];
busayFallsPhotoPatternID2 = ["1", "1_2", "10", "2", "2_2", "3", "3_2", "4", "4_2", "6", "7", "8", "9"];
*/
var busayFallsPhotoPatternLength = busayFallsPhotoPattern.length,
busayFallsPhotoPatternID2Length = busayFallsPhotoPatternID2.length;
/* setup photoURLs array */
photoArray["- Luzon -"]["Bicol Region"]["Albay"]["Busay Falls"] = {};
photoArray["- Luzon -"]["Bicol Region"]["Albay"]["Busay Falls"]["busayFallsPhotoURLs"] = {};
photoArray["- Luzon -"]["Bicol Region"]["Albay"]["Busay Falls"]["busayFallsPhotoURLs"][0] = "Cover" + ".jpg";
console.log(photoArray.[0].[0].[0].[0].[0].[0]); // this doesn't work
Probably obvious, my mind is kind of overwhelmed at the moment
I'm also wondering how to build this more efficiently / use pointers so you don't have a superLongNameLength for example.
Edit:
I think I know what's wrong, first you don't concatinate with . in JavaScript that's PHP and also I think I have to sequentially append each piece to a string to get the url after turning spaces into %20 but I'm still not sure if this is the best way to do this.
This is closer but still wrong/verbose, I'm getting the last entry which makes sense as they all have the same name.
var islandGroups = ["- Luzon -", "- Visayas -", "-Mindanao"],
regions = {
"- Luzon -" : "Bicol Region",
"- Luzon -" : "Cagayan Valley",
"- Luzon -" : "Calabarzon",
"- Luzon -" : "CAR",
"- Luzon -" : "Central Luzon",
"- Luzon -" : "Ilocos Region",
"- Luzon -" : "Mimaropa"
},
provinces = {
"Bicol Region" : "Albay",
"Bicol Region" : "Camarines Norte",
"Bicol Region" : "Camarines Sur",
"Bicol Region" : "Catanduanes",
"Bicol Region" : "Masbate",
"Bicol Region" : "Sorsogon"
},
travelDestinations = {
"Albay" : "Busay Falls",
"Albay" : "Hoyop-Hoyopan Cave",
"Albay" : "Lignon Hill",
"Albay" : "Malabsay Falls",
"Albay" : "Mt Mayon",
"Albay" : "Panicuason Hot Spring Resort",
"Albay" : "Vera Falls"
},
photos = {
"Busay Falls" : "Cover.jpg",
"Busay Falls" : "Busay_falls_10.jpg",
"Busay Falls" : "Busay_falls_2.jpg",
"Busay Falls" : "Busay_falls_3.jpg",
"Busay Falls" : "Busay_falls_4.jpg",
"Busay Falls" : "Busay_falls_5.jpg",
"Busay Falls" : "Busay_falls_6.jpg",
"Busay Falls" : "Busay_falls_7.jpg",
"Busay Falls" : "Busay_falls_8.jpg",
"Busay Falls" : "Busay_falls_9.jpg"
};
console.log(islandGroups[0]+regions["- Luzon -"]+provinces["Bicol Region"]+travelDestinations["Albay"]+photos["Busay Falls"]);
Yeah so definitely completely wrong there, the keys are the same... so instead of for example:
photos = {
"Busay Falls" : "Cover.jpg",
"Busay Falls" : "Busay_falls_10.jpg",
"Busay Falls" : "etc..."
}
It should be
photos = {
"busay_falls":[
"Cover.jpg",
"Busay_falls_10.jpg",
"etc..."
]
}
then you can build the url by going through the indexes of the arrays
like for the photos case here:
photos.busay_falls[0] // becomes Cover.jpg
Since you have n
arrays with each having a variable number of items, the best you can do is pick one element of each array recursively as follows:
const lower = ['a', 'b', 'c'] const upper = ['X', 'Y', 'Z'] const numbers = [1, 2, 3] const all = [lower, upper, numbers] // all = a 2d array // current = the i-th array of `all` we're currently operating on // result = the concatenated string function combination(all, current = 0, result = '') { if (current == all.length) { console.log(result) return } for (let i = 0; i < all[current].length; i += 1) { // concatenate a new string from the i-th array combination(all, current + 1, result + all[current][i] + '/') } } combination(all)
Applying the algorithm above to your strings requires some modifications:
result
should be encoded const baseURL = ["somesite.com"]; const islandGroups = ["- Luzon -", " - Visayas -", "-Mindanao-"]; const luzonRegions = ["Bicol Region", "Cagayan Valley", "Calabarzon", "CAR", "Central Luzon", "Ilocos Region", "Mimaropa"]; const bicolProvinces = ["Albay", "Camarines Norte", "Camarines Sur", "Catanduanes", "Masbate", "Sorsogon"]; const albayProvinceTravelDestinations = ["Busay Falls", "Hoyop-Hoyopan Cave", "Lignon Hill", "Malabsay Falls", "Mt Mayon", "Panicuason Hot Spring Resort", "Vera Falls"]; const busayFallsPhotoPattern = ["Cover", "Busay_falls_"]; const busayFallsPhotoPatternID2 = ["1", "1_2", "10", "2", "2_2", "3", "3_2", "4", "4_2", "6", "7", "8", "9"]; // all = a 2d array // current = the i-th array of `all` we're currently operating on // result = the concatenated string function combination(all, current = 0, result = '') { if (current == all.length) { // add extension console.log(result + '.jpg') return } for (let i = 0; i < all[current].length; i += 1) { // concatenate a new string from the i-th array let newString = encodeURI(result + all[current][i]) // empty string shouldn't have / // when current >= all.length - 2 we shouldn't add / if (all[current][i] && current < all.length - 2) { newString += '/' } combination(all, current + 1, newString) } } combination([ baseURL, islandGroups, luzonRegions, bicolProvinces, albayProvinceTravelDestinations, busayFallsPhotoPattern, busayFallsPhotoPatternID2 ])
