如何从 html:options 集合中获取 Selected 选项值

Question

I am having an Drop down in my JSP. How to get selected value from <html:options> tag in JSP.

<html:select property="temp_Id"  >  
<html:options collection="listmap" property="key"/>  
</html:select>  

Answer 1

Change your tag to

<html:select property="temp_Id" styleId = "tempId" >
html:options collection="listmap" property="key"/>  
</html:select>

Add the following in your java script

var e = document.getElementById("tempId");
var strUser = e.options[e.selectedIndex].value;  

This should do.Thanks.
