1、extjs2.2版本

2、js代码示例

?

//Combobox, IE and hideTrigger:true bug 
Ext.form.TriggerField.override({
    afterRender: function() {
         Ext.form.TriggerField.superclass.afterRender.call(this);
    }
});

?

{

/**
	 * 带有检索功能的客户选择
	 * @param orgNo
	 * @param query
	 * @param model
	 * @param start
	 * @param limit
	 * @return
	 */
	@RequestMapping("/data/pagingOwner.do")
	public String getPagingOwners(String searchString,Model model,Integer start,Integer limit){
		System.out.println(">>>searchString:" + searchString);
		Paging paging = dataManager.getSpellClients(searchString,0,start, limit);
		String json = "{totalCount:" + paging.getTotalCount() + ",Owners:"
				+ JSONArray.fromObject(paging.getCollections(), JsonUtils.registerDateProcessor(new JsonConfig()))
				+ "}";
		return JsonUtils.returnJsonModelAndView(model, json);
	}
