structs2 annotation +jsp+ajax Implementation post asynchronous load Select

Process:

1. Click Load BTN to initiate the asynchronous request post

2. Background processing request return data

3. Front-end acquisition of data successfully, data processing

Front:

HTML: First to import the JQ package, otherwise how to use Ajax it.

<script type= "Text/javascript" src= "Js/jquery.js" ></script>

<select name= "Warid" id= "Warid" style= "height:100%;width:107px" ><option value= "" > All warehouses </option> </select>

<script type= "Text/javascript" >$ (document). The Ready (function () {    ///is implemented here: Loads the warehouse list $ (". Add") When you click the Add button for class. Click (function () {$.post ("xxxx.do", function (data) {      ////action to be loaded asynchronously, and a successful callback var objs = data.warehouses;     The attribute in the corresponding action var selobj = $ ("#wareId");   Selobj.empty (); for (var i in Objs) {var obj = objs[i];addoption (selobj,obj.id,obj.warehousename);//Append an option to select ( Drop-down)           }}, "JSON"); return type}); }); function AddOption (selobj,value,text) {var optionstring = "<option value=\" "+ Value +" \ ">" + text + "</option > "; selobj.append (optionstring); Append an option to the Select (drop-down item)           }</script>

Backstage structs:

Using annotation implementations,

Note that the Declaration class should be annotated: @ParentPackage ("Json-default")

Method declaration Annotations: @Action (value = "xxxx", results = @Result (name = "Success", type= "JSON"))

Need to jump page to change type = "JSON" to location = "/mobile/auction_detailed.jsp" to jump to the page

@ParentPackage ("Json-default") public class Warhouseaction extends Actionsupport {@Autowiredprivate Warehouseservice  Warehouseservice;private list<warehouse> warehouses;/** * Background ajax * @return * need to jump page to change type = "JSON" to location  = "/mobile/auction_detailed.jsp" the page to jump */@Action (value = "Addgood_before", results = @Result (name = "Success", type= "json ")) public  String Addgoodbefore () {warehouses = Warehouseservice.findallenablewarehouses ();   This is the return to the page "Success";} Public Warehouseservice Getwarehouseservice () {return warehouseservice;} public void Setwarehouseservice (Warehouseservice warehouseservice) {this.warehouseservice = Warehouseservice;} Public list<warehouse> getwarehouses () {return warehouses;} public void setwarehouses (list<warehouse> warehouses) {this.warehouses = warehouses;}}
