Its simple question
I have one jquery arrary
arry = [ 'apple=1', 'apple=2', 'orange=5', 'orange=7', 'orange=9', 'guava=12', 'guava=11' ];
I want to convert above array into string
str = 'apple=1*2*~orange=5*7*9~guava=12*11';
Kindly help me in this...
(Actually I am looking for various interesting ways to do this)
There are more straightforward ways, if you know you're going for that exact output, but I would find it most useful to first rearrange the array in to a proper dictionary:
var dict = {};
arry.forEach(function(item) {
var parts = item.split('=');
var key = parts[0];
var value = parts[1];
if(key in dict) {
dict[key].push(value);
} else {
dict[key] = [value];
}
});
... and then concatenate the string from that:
Object.keys(dict).map(function(key) {
return [key, '=', dict[key].join('*')].join('');
}).join('~');
