I have problem on jquery onclick. when onclick happen on a link text box value should fill with the some hard coded text.

ex 

```
  $('#linkBase').click(function() {

         $('#txtFormula').val("txnword");

    });

```

problem is I want to repeat the "txtword" on the text box when I click on the link as "txtwordtxtwordtxtwordtxtwordtxtword" but currently I'm getting only once when click the link.
