javascript array clean function -


simple function clean array if has null or empty values, if have:

[ 'click1', 'click2', null, '', '', 'submitform' ] 

...it return:

[ 'click1', 'click2', 'submitform' ] 

here code:

function squeakyclean(arr) {   (var = 0; < arr.length; i++) {     if (arr[i] == null || arr[i] == '') {       arr.splice(i);     };   };   return arr; } 

i have loop check each value in array , if statement see if equal null or , empty string, if used array splice method remove value , return clean array outside loop.

it works if enter array no empty strings or null values, if enter [ 1, , 2, 3, 0, -1, 1.1 ] returns [1] should not do. missing here?

ps: have looked how other people solved using without loop , splice method, interested in how solve using these two.

your code fine apart use of .splice method must specify number of items on index delete.

example: array.splice(index, numberofitemsfromindex);

therefore fix code should simple as:

function squeakyclean(arr) {   (var = 0; < arr.length; i++) {     if (arr[i] == null || arr[i] == '') {       arr.splice(i, 1);     };   };   return arr; } 

(splice documentation)
