Question

Hi i have this form opening with window’s dialog:

<form method="GET" id="formparam">
<table><tbody><tr><td>
<label>ID</label></td>
<td><textarea style="height: 21px; overflow: hidden; padding-top: 0px; padding-bottom: 0px;" class="expand" id="inputp8_id"></textarea>
</td>
</tr>
</tbody></table></form>

But when i push button’s name’s Add.Function’s the script of code:

$("#wnd_Addparam").dialog({
    autoOpen: false,
    height: 'auto',
    width: 350,
    modal: true,
    resizable: false,
    buttons: {
        "Add": function() {
            contapara = (parseInt(contapara) + 1);
            var rok = $(#'inputp' + i + '_id').value;
            document.getElementById("sorpara").innerHTML += "<li id=\"inputp" + contapara + "_id\" class=\"ui-state-default\"><span class=\"ui-icon ui-icon-arrowthick-2-n-s\"></span>" + rok + "</li>";

            $(this).dialog("close");
        },
        Cancel: function() {
            $(this).dialog("close");
        }
    },
    close: function() {
        $(this).dialog("close");
    }
});

$("#btn_Addpar").click(function() {
    $("#wnd_Addparam").dialog("open");
});​

The variable’s contapara is 5.
But why the value’s variable is undefined or nothing or code’s html (with .text)?
I look at the variable i and contapara are value is correct.
Where i am wrong in this var rok =$(#'inputp'+i+'_id').value; ?
How to call the id’s textarea inputp6_id and print the content?

Answer 1

Try this below. This will get the value from within the textarea.

var contapara =(parseInt($(contapara).val())+1);

edit:

var rok =$('#inputp'+i+'_id').val();

The hash was also in the wrong place.
