php - Text box value instant show calling method -

script

  <script type="text/javascript">       function keyhandler() {           var result = document.getelementbyid('result');         result.innerhtml=document.getelementbyid('txtinput').value;      }  </script> 

html

       <input type="text" id="inputfield" />        <div id="screen"></div> 

this code work in html want

<a href="#?call=limit.lim&amp;height=400&amp;width=400&amp;id={$id}&amp;team=  {$name}&amp;val={'**********'}&amp;name={$name2}&amp;catname={$cat}"   class="inlinepopup" title="{'namer'}">{$single}</a> 

val={'****'} ever type in text box that's want here in star position how

 val={'<div id="screen"></div>'} not work 

example : type value 123 in text box means that's instant like

val = 123 

you change href attribute of link in keyhandler function.

for example:

function keyhandler(){     var inputtext = document.getelementbyid('inputfield').value;     document.getelementbyid('mylink').href = '#?yourparam=something&val='+encodeuricomponent(inputtext); } 

would work html:

<input type="text" id="inputfield" onkeydown="keyhandler()" /> <a href="#" id="mylink">link text</a> 

could adapt technique suit needs? alternatively, provide more details problem? example code, motivation, context etc?
