从servlet的html表单中检索select的标题

Question

I have an html form with a list, like below

<select name="myselect">
   <option value="101">test val 1</option>
   <option value="102">test val 2</option>
   <option value="103">test val 3</option>
</select>

I am able to retrieve the option value in my servlet, using getParameter() method

But is there any way to get the caption of the selected option (ie. eg: test val 1)

Answer 1

No. But you can bind the caption to the value in html

<option value="101:test val 1">test val 1</option>

Now split from :

String value = request.getParameter("myselect");
String val1 = value.split(":")[0];
String val2 = value.split(":")[1];

Answer 2

as Roshana mentioned above, it is possible to bind the caption with the value. But it is difficult when there is a need to access options using js or ajax. So I found a similar solution which is to copy the selected value to an hidden field and access it from servlet.

<input type="hidden" id="selectCaption">
<select onchange="document.getElementById('selectCaption').value=this.text">

this doesn't change the value and gives no complications, and can simply access the value from servlet.
