Changing values in dynamically generated html using Jquery

As the title says, I'm wondering if there's a way to change the value of html items that are generated by jquery. Here's the code that I currently have:

the javascript

<script type="text/javascript">

$(document).ready(function() {
    $('#months').change(function() {
        var currentDate = new Date();
        var curentMonth = currentDate.getMonth();
        var curentYear = currentDate.getYear();

        $(".row:not(:first)").remove();
        for (var i = 0; i < this.selectedIndex; i++)
        $(".row:first").clone(true).insertAfter(".row:last");
        $('#dateDueMonth['+i+']').val(curentMonth + 1);
    })
});

</script>

My thought here was that after the row was cloned, I could then change the dropdowns content based upon it's current name, but obviously that's not working, and I've been unable to find a way to "hook" into dynamic html content.

and the base html

<select id="months" name="months">

<option selected value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option开发者_运维知识库 value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>

<option value="10">10</option>
<option value="11">11</option>
<option value="12">12</option>
</select>
</td><div id="showRows"><div class="row" id="row[]"><td class="td_alt"><select id="dateDueMonth[]" name="dateDueMonth[]" >
<option value="0">Select</option>
<option value="1">Jan</option>
<option value="2">Feb</option>
<option value="3">Mar</option>
<option value="4">Apr</option>

<option value="5">May</option>
<option value="6">Jun</option>
<option value="7">Jul</option>
<option selected value="8">Aug</option>
<option value="9">Sep</option>
<option value="10">Oct</option>
<option value="11">Nov</option>
<option value="12">Dec</option>
</select>

 <select id="dateDueYear[]" name="dateDueYear[]">
<option value="2005">2005</option>
<option value="2006">2006</option>
<option value="2007">2007</option>
<option value="2008">2008</option>
<option value="2009">2009</option>
<option value="2010">2010</option>
<option selected value="2011">2011</option>
</select>

Now the generation of dynamic html and form submission works great. Gives me the data that I can use for my back end code. However having it so that I can increment the values in the various dropdowns as I see fit would make data entry by the folks using this page a whole lot easier, hence the issue.

To all that reply, thanks for your help with this jquery/JS noob.

EDIT: For this what I want to have is a form that can spawm multiples copies of the first line encased within the showRows div. When this is submitted, I want it to be able to collect that information in arrays for each select/input statement for the rows that are generated. For example if I selected two months, dateDueMonth, dateDueYear, and amount would be arrays in my form that would have two entries each. The current code does this, but by default it has the default elements for the dropdown menus set the same as the row of HTML that it is cloning.

Not sure what you want to do, but it should work like this

$(document).ready(function() {
    $('#months').change(function() {
        var currentDate = new Date();
        var curentMonth = currentDate.getMonth();
        var curentYear = currentDate.getYear();
        var arr;
        $(".row:not(:first)").remove();
        for (var i = 0; i < this.selectedIndex; i++)
        arr=[$(".row:first").clone(true).insertAfter(".row:last")];
        $('#dateDueMonth['+i+']').val(curentMonth + 1); //don't know why its here

        arr[0].text("your value"); //apply the index you wanna change
    })
});

Are you trying to achieve this kind of markup? Demo

<div id="showRows"><div class="row" id="row[0]"><select id="dateDueMonth[0]" name="dateDueMonth[0]">
<option value="0">Select</option>
...
</select>

<select id="dateDueYear[0]" name="dateDueYear[0]">
<option value="2005">2005</option>
...
</select>

</div><div class="row" id="row[1]"><select id="dateDueMonth[1]" name="dateDueMonth[0]">
<option value="0">Select</option>
...
</select>

 <select id="dateDueYear[1]" name="dateDueYear[0]">
<option value="2005">2005</option>
...
</select>

...

This may be what you need. See my demo linked above.

for (var i = 1; i <= this.selectedIndex; i++) {
    row = $(".row:first").clone(true)[0];
    row.id = "row["+i+"]";
    $(row).find("[id^='dateDueMonth']").attr("id","dateDueMonth["+i+"]").val((curentMonth + i) % 12 + 1);
    $(row).find("[id^='dateDueYear']").attr("id","dateDueYear["+i+"]");
    $(row).insertAfter(".row:last");
}

you cannot use ids as array in JavaScript. if you want, you have to put array index as well when you create element. or else just access the select element as bellow

$(document).ready(function() {
    $('#months').change(function() {
        var currentDate = new Date();
        var curentMonth = currentDate.getMonth();
        var curentYear = currentDate.getYear();

        $(".row:not(:first)").remove();
        for (var i = 0; i < this.selectedIndex; i++) {
            $(".row:first").clone(true).insertAfter(".row:last");
            $('.row:last select').val(curentMonth + 1);
        }
    })
});
