In this step you will define a new response WebRoutine which the AJAX enabled Dynamic Select box for sections will invoke.
1. Select the Source tab.
2. Create a new response WebRoutine, that will be invoked by the sections dynamic select box when DEPTMENT changes. The requirements for this WebRoutine are:
- The WebRoutine statement must have a Response() keyword with a value of *JSON.
- A web_map for input, field DEPTMENT.
- A web_map for output of the list SectDD, defined as a *JSON list.
- Invoke the buildDD2 method routine passing DEPTMENT and SECTION.
Your code should look like the following:
...
WebRoutine Name(USectDD)
...
Response(*JSON)
Web_
...
Map For(*input)
...
Fields(#deptment)
Web_
...
Map For(*output)
...
Fields((
...
#sectdd *JSON))
#com_owner.
...
buildDD2 I_Dept(#deptment)
...
I_Sect(#section)
Endroutine
3. Compile your WAM.
4. Open WebRoutine Details in the Design view.
5. Select the Section's dynamic select box and set up additional properties as follows:
updateOnFieldChange | DEPTMENT |
updateWrName | uSectDD |
updateFieldsToSubmit | Field: DEPTMENT |
Field Value: DEPTMENT |
...
6. Set the updateFieldsToSubmit property by selecting the Value column and clicking on the Ellipsis
...
button to open the Design of… property's dialog.
a. Select a field Name of DEPTMENT
b. For Value, enter DEPTMENT.
c. Select the Field radio button.
7. Click OK to close the dialog.
8 Save your WAM.
9. Test your WAM by running the Begin webroutine. You should now be able to select a new department and notice that the sections dropdown list is refreshed.
