Question

我正在尝试将jqgrid集成到我的xhtml页面上，并使用服务器端分页支持点击jqgrid寻呼机上的'next'，'prev'按钮。我想用点击'next'/'prev'按钮刷新存储在页面变量数组中的数据的网格，但是如果我使用'local'作为数据类型，我无法设置'records'参数。网格。我的代码如下所示 -

function reloadJQGrid(){

    $("#list").setGridParam({datatype:'local'});
    $("#list").setGridParam({localReader:{repeatitems: false}});

    var myData1 ="{\"total\":1,\"page\":1,\"records\":50,\"rows\":[" +
        "{\"id\":\"1\",\"examineeid\":\"123455\",\"firstname\":\"testfirst1\",\"middlename\":\"middle1\",\"lastname\":\"testlast1\",\"dateofbirth\":\"2007-10-01\",\"gender\":\"Male\",\"emailaddress\":\"test1@test.com\",\"customfield1\":\"nodata\",\"customfield2\":\"nodata\",\"customfield3\":\"nodata\",\"customfield4\":\"nodata\",\"createdby\":\"dfgdfg\",\"createddate\":\"2007-10-01\",\"modifiedby\":\"try\",\"modifieddate\": \"2007-10-01\",\"accountname\":\"TRGG\",\"legacyexamineeid\":\"1234\",\"legacysystem\":\"test1\",\"groups\":\"testgroup\"}," +
        "{\"id\":\"2\",\"examineeid\":\"123\",\"firstname\":\"testfirst1\",\"middlename\":\"middle1\",\"lastname\":\"testlast1\",\"dateofbirth\":\"2007-10-01\",\"gender\":\"Male\",\"emailaddress\":\"test1@test.com\",\"customfield1\":\"nodata\",\"customfield2\":\"nodata\",\"customfield3\":\"nodata\",\"customfield4\":\"nodata\",\"createdby\":\"ifgfg\",\"createddate\":\"2007-10-01\",\"modifiedby\":\"itr\",\"modifieddate\": \"2007-10-01\",\"accountname\":\"YTTT\",\"legacyexamineeid\":\"1234\",\"legacysystem\":\"rdtr\",\"groups\":\"testgroup\"}" +
        "] }";

    $("#list").jqGrid("clearGridData", true);
    $("#list").setGridParam({data:myData1});
    $("#list").trigger("reloadGrid");
}

关于这个的任何指针都会有所帮助，我试图将数据类型用作'json'，这适用于带有数据的json文件，但我不想用json数据创建临时文件，而是我的变量获取刷新数据，我想用同样的方法重新加载下一组数据。

根据jqGrid Options wiki page，“Records”是一个只读属性。

请尝试使用“reloadJQGrid”功能中的最后一步。

var records = 5000; //read this value from your server return string
$("#list").setGridParam({recordtext: "View {0} - {1} of "+records});

更新后，您的功能如下所示：

function reloadJQGrid(){
    $("#list").setGridParam({datatype:'local'});
    $("#list").setGridParam({localReader:{repeatitems: false}});
    var myData1 ="{\"total\":1,\"page\":1,\"records\":50,\"rows\":[" + 
        "{\"id\":\"1\",\"examineeid\":\"123455\",\"firstname\":\"testfirst1\",\"middlename\":\"middle1\",\"lastname\":\"testlast1\",\"dateofbirth\":\"2007-10-01\",\"gender\":\"Male\",\"emailaddress\":\"test1@test.com\",\"customfield1\":\"nodata\",\"customfield2\":\"nodata\",\"customfield3\":\"nodata\",\"customfield4\":\"nodata\",\"createdby\":\"dfgdfg\",\"createddate\":\"2007-10-01\",\"modifiedby\":\"try\",\"modifieddate\": \"2007-10-01\",\"accountname\":\"TRGG\",\"legacyexamineeid\":\"1234\",\"legacysystem\":\"test1\",\"groups\":\"testgroup\"}," +
        "{\"id\":\"2\",\"examineeid\":\"123\",\"firstname\":\"testfirst1\",\"middlename\":\"middle1\",\"lastname\":\"testlast1\",\"dateofbirth\":\"2007-10-01\",\"gender\":\"Male\",\"emailaddress\":\"test1@test.com\",\"customfield1\":\"nodata\",\"customfield2\":\"nodata\",\"customfield3\":\"nodata\",\"customfield4\":\"nodata\",\"createdby\":\"ifgfg\",\"createddate\":\"2007-10-01\",\"modifiedby\":\"itr\",\"modifieddate\": \"2007-10-01\",\"accountname\":\"YTTT\",\"legacyexamineeid\":\"1234\",\"legacysystem\":\"rdtr\",\"groups\":\"testgroup\"}" +
        "] }";
    $("#list").jqGrid("clearGridData", true);
    $("#list").setGridParam({data:myData1});
    $("#list").trigger("reloadGrid");
    var records = 5000; //read this value from your server return string
    $("#list").setGridParam({recordtext: "View {0} - {1} of "+records});

}

无法更改jqgrid中的records参数并使用阵列存储和服务器端分页重新加载数据
