Implode an array with JavaScript?

Question

Can I implode an array in jQuery like in PHP?

Answer 1

array.join was not recognizing ";" how a separator, but replacing it with comma. Using jQuery, you can use $.each to implode an array (Note that output_saved_json is the array and tmp is the string that will store the imploded array):

var tmp = "";
$.each(output_saved_json, function(index,value) {
    tmp = tmp + output_saved_json[index] + ";";
});

output_saved_json = tmp.substring(0,tmp.length - 1); // remove last ";" added

I have used substring to remove last ";" added at the final without necessity. But if you prefer, you can use instead substring something like:

var tmp = "";
$.each(output_saved_json, function(index,value) {
    tmp = tmp + output_saved_json[index];

    if((index + 1) != output_saved_json.length) {
         tmp = tmp + ";";
    }
});

output_saved_json = tmp;

I think this last solution is more slower than the 1st one because it needs to check if index is different than the lenght of array every time while $.each do not end.
