jQuery put values from array into text box but without commas

Question

I have an array ["A", "B", "C"] and I want to show the elements of the array in a text box but without comma. They will appear in the text box as like: ABC

function addtoFormula(){
    var a = ["A", "B", "C"];
    $.each([a], function( index, value ) {
        var putvalue = value;
        $("#formula").val(putvalue);
    });
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<input type="text" name="formula" id="formula">
<button onclick="addtoFormula();">Add</button>

You do not need to loop through the the array at all. Just use Array.prototype.join() with empty string ('') as the separator:

function addtoFormula(){
    var a = ["A", "B", "C"];
    $("#formula").val(a.join(''));
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<input type="text" name="formula" id="formula">
<button onclick="addtoFormula();">Add</button>

You can simply achieve this by

function addtoFormula() {
   var a = ["A", "B", "C"];
    $("#formula").val(a.join(''));
}

You can simply use the join method of the array to convert the array into a string

function addtoFormula(){
    var a = ["A", "B", "C"];
    // Note that join accept the join delimiter. Here I have 
    // space, but you can add what ever you need.
    $("#formula").val(a.join(''));     // Output: ABC
    $("#formula").val(a.join(' '));    // Output: A B C
    $("#formula").val(a.join(','));    // Output: A,B,C
    $("#formula").val(a.join(', '));    // Output: A, B, C
}
