Question

I have three modules/sectinos that basically do the same thing with some minor differences. I tried to write the main portion into a jquery function so I can just call it as needed, but I can’t structure it correctly. Could someone show me how to structure this please?

This is the part I need as a separate function and then called by the others

var mytextareaFld = $('#ta_holdAll');
        var fld_1 = $('#firstname').attr('name')+':  '+$('#firstname').val();
        var fld_2 = $('#lastname').attr('name')+':  '+$('#lastname').val();
        var fld_3 = $('#street_number').attr('name')+':  '+$('#street_number').val();
        mytextareaFld.val(fld_1 +'\n' + fld_2 +'\n' + fld_3);

html/jquery code below:

<form>
    <p>First name: <input type="text" name="firstname" id="firstname" value="Paul"/></p>
    <p>Last name: <input type="text" name="lastname"  id="lastname" value="Ryan" /></p>
<p>Street #: <input type="text" name="street_number"  id="street_number" value="4605"/></p>
<p>Address: <input type="text" name="address" id="address"/></p>
<p>City: <input type="text" name="city" id="city" /></p>
<p>State: <input type="text" name="state" id="state"/>

<span id="myzip">Zip:</span> <input type="text" name="zip"  id="zip" />
    <br /><br />
<span id="allInfo">All Info:</span> <textarea id="ta_holdAll" rows="10" cols="30"></textarea><div id="charCnt"></div><br /><br />
    <input type="button" value="Add to Field" id="addField">
</form>

    $(document).ready(function(){
    $('#addField').on('click',function(){
        var mytextareaFld = $('#ta_holdAll');
        var fld_1 = $('#firstname').attr('name')+':  '+$('#firstname').val();
        var fld_2 = $('#lastname').attr('name')+':  '+$('#lastname').val();
        var fld_3 = $('#street_number').attr('name')+':  '+$('#street_number').val();
        mytextareaFld.val(fld_1 +'\n' + fld_2 +'\n' + fld_3);
    });

    $('#allInfo').on('click',function(){
        var mytextareaFld = $('#ta_holdAll');
        var fld_1 = $('#firstname').attr('name')+':  '+$('#firstname').val();

        mytextareaFld.val(fld_1 +'\n' + fld_2 +'\n' + fld_3);
        var $mytextareaFld = $('#ta_holdAll');
        var $outPutCount = $("#charCnt");
        var $ofText = " characters of 1000 remaining";
        var val = $mytextareaFld.val();
        var val2 = $outPutCount.text(val.length).append("<strong>"+$ofText+"</strong>");
    });

    $("#firstname,#lastname, #street_number").blur(function(){
