Answer 1

Here you go - fiddle

Don't reuse id s on html elements. An id should be unique, use class instead.

 var a = $('#myList_1 > .x'); $('button').click(function(){ $(a).remove(); });

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div id="myList_1"> <span class="x">111111</span> </div> <div id="myList_2"> <span class="x">222222</span> </div> <button>Try it</button>

Answer 2

Duplicate "x" id s at span elements ? Try adding "1" , "2" , respectively , to span id property to substitute unique id s in document for duplicate id s at span elements

 <div id="myList_1"> <span id="x1">111111</span> </div> <div id="myList_2"> <span id="x2">222222</span> </div> <button onclick="myFunction(2)">Try it</button> <script> function myFunction(data_value) { var list = document.getElementById("myList_" + data_value); var x_child = document.getElementById("x" + data_value); list.removeChild(x_child); } </script>

Answer 3

You have 2 id s that are the same, id s should be unique.

Here is a version that uses classes instead (which dont have to be unique):

<div id="myList_1">
    <span class="x">111111</span>
</div>
<div id="myList_2">
    <span class="x">222222</span>
</div>
<button onclick="javascript: myFunction(2)">Try it</button>

<script>
function myFunction(data_value) {
    var list = document.getElementById("myList_"+data_value);
    var x_child=list.getElementsByClassName("x")[0];
    list.removeChild(x_child);                                 
}
</script>

$("#myList_2").innerHTML = ''
