查找，替换和附加新的dom元素

Question

My goal is to go through a table and append a new <tr> with the same data as it's previous sibling but with some altered content text.

A section of my html is as follows:

<tr>
  <td><label>Share - Spanish</label></td>
  <td><input type="text" id="blog_share_es" name="blog_share_es" size="30" /></td>
</tr>

Within my current function in Javascript the $(this) is the <label> tag. I have successfully taken the word "Spanish" and replaced it with "Italian" with the following:

    var italian = $(this).text().replace("Spanish", "Italian");

and then append it to the table as follows:

var parentDiv = $(this).parent().parent();
$('<tr><td><label>'+italian+'</label></td><td><input type="text" id="logout_de" name="logout_de" size="30"/></td></tr>').insertAfter(parentDiv);

How do I now select the <input> and replace all instances of "_es" within the id and name with "_it" so that I get the following output in html (getting the formatting of the html is not necessary but would be optimal!):

<tr>
  <td><label>Share - Italian</label></td>
  <td><input type="text" id="blog_share_it" name="blog_share_it" size="30" /></td>
</tr>

Turned into a plug-in

DEMO

(function ($) {
    $.fn.newRow = function (language, suffix) {
        $lastSibling = this.find("tr").last().clone();
        $label = $lastSibling.find("label");
        $labelText = $label.text();
        $label.text($labelText.replace($labelText.substring($labelText.indexOf("- ") + 2), language));
        $input = $lastSibling.find("input");
        $id = $input.attr("id");
        $name = $input.attr("name");
        $input.attr("id", $id.replace($id.substring($id.lastIndexOf("_") + 1), suffix))
              .attr("name", $name.replace($name.substring($name.lastIndexOf("_") + 1), suffix));
        this.find("tbody").append($lastSibling);
        return this;
    };
})(jQuery);

$("#yourTable").newRow("Italian", "it");

something like this... not sure if it 100% works, but gives you right direction

$('input[type=text]').each(function(input) {
    if (input.attr('id').match(/_it/))
        input.attr('id', input.attr('id').replace(/_it/, '_es');
    if (input.attr('name').match(/_it/))
        input.attr('name', input.attr('name').replace(/_it/, '_es');
})

To select the input starting from $(this) you have to use the function find() , and then you can change the attributes using the function attr()

var inp = $(this).parent().parent().find("input[type=text]");
inp.attr("id", inp.attr("id").replace("_es","_it"));
inp.attr("name", inp.attr("name").replace("_es","_it"));
