jqgrid学习笔录

$("#list").trigger("reloadGrid"); //重新载入jqGrid数据

1 Struts2参数冲突，修改jqgrid.js
        searchString改 search_String; 
searchOper;改search_Oper; 
searchField;改search_Field1;

2 Struts2 编码GBK 导致乱码（设置提交为 AJAX，修改Struts2当表单是Ajax编码为UTF-8）：$("#gridTable").jqGrid({
url : "jqGrid01.action",
loadBeforeSend: function(xhr) {
        return xhr.setRequestHeader('isAjax', 'true');
    },



修改struts2.3.1.2源码org.apache.struts2.dispatcher.Dispatcher第677行prepare方法
    原来是：
    if (defaultEncoding != null) {
        encoding = defaultEncoding;
    }
    修改为：
    if (request.getHeader("isAjax") != null) {//判断是否是ajax请求，是的话则采用encoding=utf-8编码
    encoding = "UTF-8";
    LOG.debug("ajax request");
} else if (defaultEncoding != null) {
    encoding = defaultEncoding;
}


struts2定义父类属性同时返回json数据
<result type=”json”> 
<param name=”ignoreHierarchy”>false</param> 
</result
