Onchange Split text appendTo text and join back together

Hi guys!
I would like to append a value to href element of an achor from select box, after selecting one of its elements.

I would like to append it to the &B=two
So after selecting one of elements value of href is
"A=one&B=two&(selectedOptionValue)&path=somePath"

I am using jquery library, but don't mind using regular javascript with this task.

I will be very greatfull for any help!

Thanks!
<select onchange="appendToAnchor">
<option value="c=three">option1</option>
<option value="c=four">option2</option>
<option value="c=five">option3</option>
</select>
<a href="?A=one&b=two&path=somePath">go</a>

1. Add an ids to <select> and <a>

<select id="sel1" onchange="appendToAnchor()">
<option value="c=three">option1</option>
<option value="c=four">option2</option>
<option value="c=five">option3</option>
</select>
<a href="?A=one&b=two&path=somePath">go</a>
 
<a id="anchor1" href="?A=one&b=two&path=somePath">go</a>

2. Define JS function appendToAnchor()

function appendToAnchor()
{
    var op = document.getElementById('sel1').value;
    document.getElementById('anchor1').href = document.getElementById('anchor1').href.replace(/&b=two/i, "&b=two&"+op);

}

mark up

        <select onchange="appendToAnchor(this.value)">
<option value="c=three">option1</option>
<option value="c=four">option2</option>
<option value="c=five">option3</option>
</select>
<a href="?A=one&b=two&#path=somePath" id="aTag" >go</a>

javascript
    function appendToAnchor(e)
    {
      var lnk = document.getElementById("aTag").href;
      lnk = lnk.replace("#path",e);
      document.getElementById("aTag").href = lnk

    }


just created an ID for anchor tag to easily identify the anchor tag and used #path instead of path to easily identify the string.

I guess you need to replace somepath with selected value...little change

        <select onchange="appendToAnchor(this.value)">
<option value="c=three">option1</option>
<option value="c=four">option2</option>
<option value="c=five">option3</option>
</select>
<a href="?A=one&b=two&path=#somePath" id="aTag" >go</a>

javascript
    function appendToAnchor(e)
    {
      var lnk = document.getElementById("aTag").href;
      lnk = lnk.replace("#somepath",e);
      document.getElementById("aTag").href = lnk

    }
