<input type="text" id="text"/>
<br/>
<input type="button" onClick="changeValue()" value="Change Value"/>
<p/>
<input type="text" id="result"/>
<script>
function changeValue(){
 document.getElementById("result").value = document.getElementById("text").value;
}
</script>

Используя class:

Enter text to be the value of the second input field:<br/>
    <input type="text" class="text"/>
    <br/>
    <input type="button" onClick="changeValue()" value="Change Value"/>
    <p/>
    <input type="text" class="result"/>
    <script>
    function changeValue(){
     document.getElementsByClassName("result")[0].value = document.getElementsByClassName("text")[0].value;
    }
    </script>

    <input type="text" class="text"/>

        window.onload = function(){
         document.getElementsByClassName("form-control")[0].value = "your value";
        }
        </script>
    <div class="contacts_modal_search">
      <input class="form-control contacts_modal_search_field no_outline ng-pristine ng-valid ng-empty ng-touched" my-focused="" type="search" placeholder="" ng-model="search.query" autocomplete="off" style="">
      <a class="im_dialogs_search_clear tg_search_clear ng-hide" ng-click="search.query = ''" ng-show="search.query.length" style="">
        <i class="icon icon-search-clear"></i>
