If I have a list of items like this in any text-area, I can use a bookmarklet to sort the unique values.
a
b
d
c
c
I click on the bookmarklet and the list is corrected to:
a
b
c
d
code:
javascript: (
function() {
Array.from(document.querySelectorAll('textarea')).map(function(b) {
var a = document.createElement('div');
var d = document.createElement('button');
d.textContent = '↑';
d.addEventListener('click', function(f) {
f.preventDefault();
b.value = Array.from(new Set(b.value.split('\n'))).sort().join('\n')
});
var c = document.createElement('button');
c.textContent = '↓';
c.addEventListener('click', function(f) {
f.preventDefault();
b.value = Array.from(new Set(b.value.split('\n'))).sort().reverse().join('\n')
});
a.appendChild(d);
a.appendChild(c);
b.parentNode.insertBefore(a, b)
})
}
)();
But this does not work if all the items are on the same line like this...
a , b,d , c,c
Is it possible to modify the code to return the items like this...
a, b, c, d
I can do that in python. But I will like to know if it is possible using JavaScript bookmarklet.
myl = [i.strip() for i in text.split(',')]
myl.sort()
', '.join(set(myl))
This would work better because since your input has blank spaces in it ,we have to use regex to split the string.
b = Array.from(
new Set(b.split(/[ ,]+/))).sort().reverse().join(',')
On this line:
b.value = Array.from(
new Set(b.value.split('\n'))).sort().reverse().join('\n')
You just need to change '\n' to ,, like:
b.value = Array.from(
new Set(b.value.split(','))).sort().reverse().join(',');
b.value.forEach(item => item.trim()); //to remove trailing whitespaces
You could try lodash for this purpose, As mentioned in other answers that you need to first change the words format from : a b d c c to : a,b,d,c,c
if changed
let x= // your values e.g a,b,d,c,c
//
let valuesArray=_.split(x,',')
uniqueFromArray=_.uniq(valuesArray)
if unchanged
let x= // your current input values
//
let valuesArray=_.split(x,'\n')
uniqueFromArray=_.uniq(valuesArray)
