Need Help On Combo Box Population VERY URGENT REQUIREMENT

["Srinivasula Reddy A , Bangalore" <sr...@hcl.in>]

Hi Struts User Community,

 

I need a rough IDEA / CODE on there are  three combo boxes are there
depending on the first combo box selection second combo box has to
populate and depending on the second combo box selection third one has
to populate.

 

Like populating all the states of country in a combo box when I select a
county in another combo box. Again if I select state in the combo box I
have to populate all the districts in another combo box

 

What are the tags I have to use in my JSP and what is the code I have to
write in my ACTION class.

 

Regards,

Sreenivasula Reddy A

BTW it is not related to struts but javascript n client programming query ?


For the sake I am giving u a hint.

It is the way how you are going to set the pattern according to single entry
change.
Take all the required data into the page and set the pattern accordingly.
i.e on change event you have to call a function to populate the pattern.

Get elements

var sel1 = document.getElementById(id1);   // Country
var sel2 = document.getElementById(id2); // State

Set pattern

var pattern1 = /( |^)(select)( |$)/;
var pattern2 = new RegExp("( |^)(" +  sel1.options[sel1.selectedIndex].value
+ ")( |$)");

Match the pattern

var clonedOptions = clone.getElementsByTagName("option");
 for (var i = 0; i < clonedOptions.length; i++) {
         if (clonedOptions[i].className.match(pattern1) ||
              clonedOptions[i].className.match(pattern2)) {
             sel2.appendChild(clonedOptions[i].cloneNode(true));
         }




Thanks and Regards,
Kapil Sharma
