How use Regex from uncheck all files by file formats

i need uncheck many files from this HTML with JQuery HTML:

<div class="well">
  <h2>Select you files</h2>
  <table id="list-files" class="table table-bordered table-striped table-condensed table-hover">
    <tbody>
      <tr>
        <th width="10px"><input type="checkbox" id="select-all-files" checked="checked"></th>
        <th>File</th>
        <th>Size</th>
      </tr>
      <tr class="selectedFiles" style="display: table-row;">
        <td><input type="checkbox" name="files[]" value="0" checked=""></td>
        <td>
          <div><span class="pull-left">The.Blind.Side.2009.1080p.BluRay.x264.DTS-FGT/</span><span style="padding-top:1px;padding: 0 2px;display:block;overflow:hidden"><input style="width:100%;color:#c8c8c8;background-color:transparent;padding:0px;margin:0px" type="text" name="rename[0]" value="Visit thist Web.com.txt"></span></div>
        </td>
        <td>34.0 iB</td>
      </tr>
      <tr class="selectedFiles" style="display: table-row;">
        <td><input type="checkbox" name="files[]" value="1" checked=""></td>
        <td>
          <div><span class="pull-left">The.Blind.Side.2009.1080p.BluRay.x264.DTS-FGT/</span><span style="padding-top:1px;padding: 0 2px;display:block;overflow:hidden"><input style="width:100%;color:#c8c8c8;background-color:transparent;padding:0px;margin:0px" type="text" name="rename[1]" value="The.Blind.Side.2009.1080p.BluRay.x264.DTS-FGT.mkv"></span></div>
        </td>
        <td>8.8 GiB</td>
      </tr>
      <tr class="selectedFiles" style="display: table-row;">
        <td><input type="checkbox" name="files[]" value="2" checked=""></td>
        <td>
          <div><span class="pull-left">The.Blind.Side.2009.1080p.BluRay.x264.DTS-FGT/</span><span style="padding-top:1px;padding: 0 2px;display:block;overflow:hidden"><input style="width:100%;color:#c8c8c8;background-color:transparent;padding:0px;margin:0px" type="text" name="rename[2]" value="The.Blind.Side.2009.1080p.BluRay.x264.DTS-FGT.nfo"></span></div>
        </td>
        <td>5.4 KiB</td>
      </tr>
    </tbody>
  </table>
</div>

SCRIPT:

var inp=$("tr input");
var r="Visit thist Web.com.txt";
for (i = 0; i < inp.length; i++) {
 if(inp[i].value == r){
  inp[i-1].checked = false;
 }
}

How to improve this code?

This script uncheck only var r="Visit thist Web.com.txt"; and i need uncheck all files with .txt! it's true this example only has one .txt, but that usually changes, even the order. I would also like to unmark files with .nfo, .url, jpg, gif that's why I suppose it would be best to do it with regex

for tampermonkey on chrome

Thank
