How to parse a JSON Object when using multiSearch for jqGrid with Java

jogep — Sat, 05 Jun 2010 22:42:45 +0000

This is a tutorial that shows how to handle a JSON Object that is received in a Struts2 Action. This Example is based on the Struts2 Grid Showcase for the Struts2 jQuery Plugin with Grid Extension. 1. First we need to enable the Multi Search Feature for the Grid Component.

< sjg :grid 
	id="customerstable" 
	...
	navigatorSearch="true"
	navigatorSearchOptions="{multipleSearch:true}"
	...
>

Now we can use the multiple search feature like this. 2.) After this we need a String property filter in our Struts2 Action.

private String filters;
 
public void setFilters(String filters) {
	this.filters = filters;
}

3.) Now we receive a JSON Object when we use the Search in the Navigator of the Grid. The JSON looks like this example.

{
	"groupOp":"AND",
	"rules":[
		{
			"field":"customernumber",
			"op":"lt",
			"data":"200"
		}
		,
		{
			"field":"country",
			"op":"eq",
			"data":"USA"
		}
		]
}

4.) To work with this, we need to serialize this as a JSONObject.

JSONObject jsonFilter = (JSONObject) JSONSerializer.toJSON( filters );

5.) Now we can get the value from the JSON Object. First we get the parameter groupOp.

String groupOp = jsonFilter.getString("groupOp");
log.debug("groupOp :" + groupOp);

6.) Now we need the rules as JSONArray and the size of this array.

JSONArray rules = jsonFilter.getJSONArray("rules");
int rulesCount = JSONArray.getDimensions(rules)[0];
log.debug("Count Rules :" + rulesCount);

7.) In a simple for-loop we can get the values of the rule.

for (int i = 0; i < rulesCount; i++) {
	JSONObject rule = rules.getJSONObject(i);
	log.debug("field :" + rule.getString("field"));
	log.debug("op :" + rule.getString("op"));
	log.debug("data :" + rule.getString("data"));
}

Now you should be able to use this values to build a custom SQL query or build an hibernate criteria.

Struts2 jQuery Plugin Version 2.1.0 is released

jogep — Sat, 01 May 2010 20:09:51 +0000

The new version 2.1.0 of Struts2 jQuery Plugin is released. With this new version, the plugin loads dependent JavaScript files on demand. This feature makes the plugin much better extensible for own extensions and reduces the initial load of the first load of a page. Based on the new structure of the plugin the jqGrid Feature is not longer a part of the core plugin. It is now available as a separate extension of the plugin. There is also a new richtext extension available, that is based on the latest version of popular CKEditor. This allows an easy integration of the richtext editor in your web application. The Plugin includes now the latest version of jQuery UI 1.8.1, so if you use a custom theme it is recommended to update this in the ThemeRoller. For more informations and the changelog for 1.8.1 please read the blog post from jQuery UI. Changelog:
