<select name="item">
<c:forEach items="${combo}" var="id">
<option value="${id}">${id}</option>
</c:forEach>
</select>
How can we get the selected value from the above dropdown list?
This question is related to
jsp
I've got one more additional option to get value by id:
var idElement = document.getElementById("idName");
var selectedValue = idElement.options[idElement.selectedIndex].value;
It's a simple JavaScript solution.
<%-- if you want to select value from drop-downlist here is jsp code. --%>
<body>
<form name="f1" method="get" action="#">
<select name="clr">
<option>Red</option>
<option>Blue</option>
<option>Green</option>
<option>Pink</option>
</select>
<input type="submit" name="submit" value="Select Color"/>
</form>
<%-- To display selected value from dropdown list. --%>
<%
String s=request.getParameter("clr");
if (s !=null)
{
out.println("Selected Color is : "+s);
}
%>
</body>
use jquery
$("#item").change(function({
var x=$(this).val();
});
Your value will be in x variable, use this variable value in your jsp, like this {x} this statement will give the value
Direct value should work just fine:
var sel = document.getElementsByName('item');
var sv = sel.value;
alert(sv);
The only reason your code might fail is when there is no item selected, then the selectedIndex returns -1 and the code breaks.
I know that this is an old question, but as I was googling it was the first link in a results. So here is the jsp solution:
<form action="some.jsp">
<select name="item">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<input type="submit" value="Submit">
</form>
in some.jsp
request.getParameter("item");
this line will return the selected option (from the example it is: 1, 2 or 3)
