arrays - odd results from nested for loops javascript -


i'm trying check submitted string against letterset. if word_string = "gar", should return "gar" because these letters appear in letterset.

for reason, words appear correctly, , appear missing letters. example, word_string = "rag", returns "r". "fig" returns "fg".

letterset = {0: "r", 1: "a", 2: "g", 3: "a", 4: "o", 5: "e", 6: "f", 7: "i"}       var ls = [];     (prop in letterset) {         ls.push(letterset[prop]);      };     console.log(ls)     var word_string = '';     var word = document                .getelementbyid('word_container')                .childnodes;     (var in word) {         var w = word[i].innerhtml;          (var prop=0; prop<ls.length; prop++) {             if (ls[prop] == w) {                 console.log(w);                 word_string += w;                 ls.splice(prop);              }          }  }

i think using splice incorrectly, regardless bit on complicated try:

 (var in word) {     var w = word[i].innerhtml;     if (ls.indexof(w)> -1) {             word_string += w;         }      }
