当我使用javascript点击它时如何获得相应的标签值

Question

How to get corresponding label value when i click on it for following jsp using javascript

This is my jsp page.

<%
for( int i = 0; i < sam.groupName.length; i++ ) {%>
<a href='JavaScript:validation();'>
   <img src='registerButton.jpg'>
   <label for='groupsId' id='labeld"+i+"'><%=sam.groupName[i]%>" </label>
 </a>
<% } %>





<script type="text/javascript">

 function validation(){
   alert("script");
 }
 </script>

Answer 1

<a href='#' onclick='validation(this)'>

(this will pass the <a> element as the first argument to validation() )

and then

function validation(anchor) {
    alert(anchor.getElementsByTagName("label")[0].textContent);
}
