How to remove the text after input field using jquery?

How can I remove the text after the input in jQuery?

jQuery

<div id="date_filter_si">
    <input type="radio" class="date_action" name="date_action" value="Y" checked=""> year
    <input type="radio" class="date_action" name="date_action" value="W" checked=""> Weekly
</div>

Expected Output

<div id="date_filter_si">
    <input type="radio" class="date_action" name="date_action" value="Y" checked=""> 
    <input type="radio" class="date_action" name="date_action" value="W" checked=""> 
</div>

$( "#date_filter_si:contains('Weekly')" ).remove();

You can use Node.nextSibling property to change next sibling text of element.

$("#date_filter_si > input")[0].nextSibling.textContent = "";

$("#date_filter_si > input")[0].nextSibling.textContent = "";

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="date_filter_si">
  <input type="radio" class="date_action"> year
</div>

If you have multiple input and sibling text use this:

$("#date_filter_si > input").each(function(){
    this.nextSibling.textContent = "";
});

$("#date_filter_si > input").each(function(){
  this.nextSibling.textContent = "";
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="date_filter_si">
  <input type="radio" class="date_action"> year
  <input type="radio" class="date_action"> week
</div>
