I'm trying to iterate over a "value" list and convert it into a string. Here is the code:
var blkstr = $.each(value, function(idx2,val2) {
var str = idx2 + ":" + val2;
alert(str);
return str;
}).get().join(", ");
alert() function works just fine and displays the proper value. But somehow, jquery's .get() function doesn't get the right sort of object and fails. What am I doing wrong?
If value is not a plain array, such code will work fine:
var value = { "aaa": "111", "bbb": "222", "ccc": "333" };
var blkstr = [];
$.each(value, function(idx2,val2) {
var str = idx2 + ":" + val2;
blkstr.push(str);
});
console.log(blkstr.join(", "));<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>(output will appear in the dev console)
As Felix mentioned, each() is just iterating the array, nothing more.
Converting From Array to String is So Easy !
var A = ['Sunday','Monday','Tuesday','Wednesday','Thursday']
array = A + ""
That's it Now A is a string. :)
You can use .toString() to join an array with a comma.
var array = ['a', 'b', 'c'];
array.toString(); // result: a,b,c
Or, set the separator with array.join('; '); // result: a; b; c.
