javascript - jQuery need to change only text content in an element -


i have 2 li elements having icon,text in each element. want change first li icon , text on button click. replacing whole anchor tag content if use .text() 

$(document).ready(function(){    $("#changeicon").click(function(){      $("#listitems li:eq(0) span").removeclass("ic1").addclass("ic3");      //$("#listitems li:eq(0) a").text("icon3");//uncomment line , check    });  });
span {    display:block;    width:32px;    height:32px;  }  .ic1 {    background:url("https://cdn4.iconfinder.com/data/icons/wirecons-free-vector-icons/32/menu-alt-32.png") no-repeat;  }  .ic2 {    background:url("https://cdn0.iconfinder.com/data/icons/navigation-set-arrows-part-one/32/grid-32.png") no-repeat;  }  .ic3 {    background:url("https://cdn2.iconfinder.com/data/icons/4web-3/139/menu-32.png") no-repeat;  }  .ic4 {    background:url("https://cdn3.iconfinder.com/data/icons/eightyshades/512/45_menu-32.png") no-repeat;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>  <ul id="listitems">      <li>          <a href="">              <span class="ic1"></span>              icon1              <span class="ic1"></span>          </a>      </li>      <li>          <a href="">              <span class="ic2"></span>              icon2              <span class="ic2"></span>          </a>      </li>  </ul>  <input type="button" id="changeicon" value="change 1 3">

is there way can change text only?

please don't provide me $("#listitems li:eq(0) a").html('<span class="ic3"></span>icon3<span class="ic3"></span>')? know.

if can't put text in it's own span element, try this:

        $(document).ready(function(){        $("#changeicon").click(function(){          $("#listitems li:eq(0) span").removeclass("ic1").addclass("ic3");          $("#listitems li:eq(0) a").contents().filter(function() {              return this.nodetype === 3; //node.text_node    })[1].textcontent = "icon3";          //$("#listitems li:eq(0) a").text("icon3");//uncomment line , check        });      });
span {    display:block;    width:32px;    height:32px;  }  .ic1 {    background:url("https://cdn4.iconfinder.com/data/icons/wirecons-free-vector-icons/32/menu-alt-32.png") no-repeat;  }  .ic2 {    background:url("https://cdn0.iconfinder.com/data/icons/navigation-set-arrows-part-one/32/grid-32.png") no-repeat;  }  .ic3 {    background:url("https://cdn2.iconfinder.com/data/icons/4web-3/139/menu-32.png") no-repeat;  }  .ic4 {    background:url("https://cdn3.iconfinder.com/data/icons/eightyshades/512/45_menu-32.png") no-repeat;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>  <ul id="listitems">      <li>          <a href="">              <span class="ic1"></span>              icon1              <span class="ic1"></span>          </a>      </li>      <li>          <a href="">              <span class="ic2"></span>              icon2              <span class="ic2"></span>          </a>      </li>  </ul>  <input type="button" id="changeicon" value="change 1 3">
