      hi ...

      welcome to TSDN. onclick of your checkbox you have to call a function that loops through the textboxes and set/remove the disabled attribute of them. please post some code you have done so far ...

      kind regards

              do you have the ids 'keyword0' ... 'keyword10' in your document?

              have a look at the following example:

              [CODE=html]
              <html>
              <script>
              function toggle_tb_state (state) {
              for (var i = 1; i <= 4; i++) {
              var tb = document.getEle mentById('keywo rd'+i);

              if (state) {
              tb.setAttribute ('readonly', 'true');
              } else {
              tb.removeAttrib ute('readonly') ;
              }
              }
              }
              </script>
              <body>
              <input type="text" id="keyword1"/>
              <input type="text" id="keyword2"/>
              <input type="text" id="keyword3"/>
              <input type="text" id="keyword4"/>
              <input type="checkbox" onclick="toggle _tb_state(this. checked);"/>
              </body>
              </html>
              [/CODE]

              kind regards

                              ;) ... that's a question besides the original problem ... so you normally should create a new thread for this. but the answer to this one is simple: you cannot! imagine a website that may retrieve the contents of any folder on you machine ... fortunatly this is not possible ;) ...
