Invert names of IDs in a form using Javascript -


i have following form:

<form id="currency" name="form" onsubmit="return redirect(this)">      <div style="clear:both;text-align: center;">         <select id="firstcurrency" class="selex" name="firstcurrency" style="float: left;">             <option value="usd">usd</option>             <option value="btc">btc</option>         </select>          <span style="margin: 0 auto;">=</span>          <select id="secondcurrency" class="selex" name="secondcurrency" style="float: right;">             <option value="btc">rrr</option>             <option value="xvg">xvg</option>             <option value="xrp">xrp</option>             <option value="ntx">ntx</option>         </select>         <p style="clear: both;"></p>       <p><input class="button" type="submit" value="redirect me" ></p>     <a href="convertitore-home"><img src="/images/invert.png">invert select</a> </form>

when click on a tag (outside form), want 2 things: 1) invert values of ids , names in 2 select in form above 2) change float values left right in first select , right left in second select.

after click on a tag, form should become:

<form id="currency" name="form" onsubmit="return redirect(this)">      <div style="clear:both;text-align: center;">         <select id="secondcurrency" class="selex1" name="secondcurrency" style="float: right;">             <option value="usd">usd</option>             <option value="btc">btc</option>         </select>          <span style="margin: 0 auto;">=</span>          <select id="firstcurrency" class="selex2" name="firstcurrency" style="float: left;">             <option value="btc">rrr</option>             <option value="xvg">xvg</option>             <option value="xrp">xrp</option>             <option value="ntx">ntx</option>         </select>         <p style="clear: both;"></p>       <p><input class="button" type="submit" value="redirect me" ></p>     <a href="convertitore-home"><img src="/images/invert.png">invert select</a> </form>

it should again each time press a tag.

what javascript code use that?

add separate css currencies use :

$('#invert').click(function(){      var firstcurr = $('#firstcurrency'),          secondcurr = $('#secondcurrency'),          tmpid = secondcurr.attr('id');      secondcurr.attr('id',firstcurr.attr('id'));      secondcurr.attr('name',firstcurr.attr('id'));      firstcurr.attr('id',tmpid);      firstcurr.attr('name',tmpid);  });
#secondcurrency {    float:right;  }  #firstcurrency {    float:left;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <form id="currency" name="form" onsubmit="return redirect(this)">    <div style="clear:both;text-align: center;">    <select id="firstcurrency" class="selex" name="firstcurrency">      <option value="usd">usd</option>      <option value="btc">btc</option>    </select>      <span style="margin: 0 auto;">=</span>      <select id="secondcurrency" class="selex" name="secondcurrency">      <option value="btc">rrr</option>      <option value="xvg">xvg</option>      <option value="xrp">xrp</option>      <option value="ntx">ntx</option>    </select>    <p style="clear: both;"></p>  </div>       <p><input class="button" type="submit" value="redirect me" ></p>       <a id="invert" href="javascript:void(0)"><!--href="convertitore-home"<img src="/images/invert.png">-->invert select</a>
