一旦选择了下拉菜单，请更改文本字段（在1页上有多种表格）

Question

I'm looking to change the value of a <p> tag once an option from a drop down has been selected. I have that working but my issue is I am going to have lots of forms on one page and feel like I am repeating my code. Is there a way to do this with a function for example? To save me writing a new section of javascript everytime a form gets added to my page?

My javascript code:

    $('.orderProduct select#packageOption').change(function(){
        $('#packagePrice').html($(this).val());
    });

    $('.orderProduct2 select#packageOption').change(function(){
        $('#packagePrice2').html($(this).val());
    });

Thanks.

Add a data-element-id attribute to each select like:

<select data-element-id="packagePrice">...</select>
<select data-element-id="packagePrice2">...</select>

then you simply need this jQuery code:

$('select[data-element-id]').change(function(){
    var $this = $(this);
    var id = $this.data('element-id');    
    $('#' + id).html($this.val());
});

If you want to avoid the extra attribute you could use jQuery's DOM traversing functions, to locate which p you should update.
