我有一个问题,当网格为空时为什么显示Page 1 of 0
不能是Page 1 of 1
或更合理的东西?
我的代码
var xml=client.responseText;
var xmlDoc = $.parseXML(xml);
var $xml = $(xml);
xml=xml.replace(/<productId>1/g, "<productId>"+productMap['1']);
xml=xml.replace(/<productId>2/g, "<productId>"+productMap['2']);
xml=xml.replace(/<productId>3/g, "<productId>"+productMap['3']);
$('#configDiv').empty();
$('#configDiv').html( '<div id="configDetailsGrid" width="100%"><table id="list1" width="100%"></table><div id="gridpager"></div></div>');
//var grid = jQuery("#list1");
//var iconAlert;
var getColumnIndexByName = function (grid, columnName) {
var cm = grid.jqGrid('getGridParam', 'colModel'), i = 0, l = cm.length;
for (; i < l; i += 1) {
if (cm[i].name === columnName) {
return i; // return the index
}
}
return -1;
},
grid = jQuery("#list1"),
iconAlert = '<span class="ui-state-error" style="border:0"><span class="ui-icon ui-icon-alert" style="float: left; margin-right: .3em;"></span></span>';
grid.jqGrid({

我的Xmldata(空的时候)
<Response>
<isSuccess>true</isSuccess>
<operation>viewall</operation>
<message>No configurations loaded</message>
</Response>
更新
我相应地更新了但是仍然没有运气,我仍然得到相同的旧Page 1 of 0
xmlReader: {
/*root : "list",
row: "Response",*/
root:"Response",
row:"list",
userdata: "userdata",
repeatitems: false
},
我的 jquery.jqGrid.min.js 文件更改
if(locdata) {
ts.p.records = gl;
//Change after 1 of 0 (Oleg)ts.p.lastpage = Math.ceil(gl/ rn);
ts.p.lastpage = Math.max(ts.p.page,Math.ceil(gl/ rn)); //line no 1181
}
我的回复
<Response>
<isSuccess>true</isSuccess>
<operation>viewall</operation>
<message>No configurations loaded</message>
</Response>
更新,有用的东西
如果我们重新加载网格,它也解决了问题
jQuery("#list1").setGridParam({rowNum:10}).trigger("reloadGrid");

我没有看到XML数据与您使用的xmlReader
相对应。您可能应该切换root
和row
属性的值:
xmlReader: {
root : "list",
row: "Response",
userdata: "userdata",
repeatitems: false
}
此外,输入XML数据不包含page
,total
和records
属性。如果使用任何其他datatype
作为'xml'
或'xmlstring'
,您可以将page
,total
和records
定义为{{ 1}}。 jsonReader
参数不支持它。
目前,您尚未定义xmlReader
,page
和total
属性。因此,使用默认值:records
,page: "rows>page"
,total: "rows>total"
。
我在the answer和the bug report中描述的错误仍未在jqGrid 4.2.0的代码中修复。因此,在应用修复程序之前,您当前的数据将显示“1 NaN”。
毕竟,您可以考虑更改jqGrid代码的行1193
records: "rows>records"
在ts.p.lastpage = Math.ceil(gl/ rn);
。
更新:我建议您将jqGrid代码的行lastpage
修改为ts.p.lastpage = Math.ceil(gl/ rn);
。
如果您的输入数据不包含ts.p.lastpage = Math.max(ts.p.page,Math.ceil(gl/ rn));
元素,或者包含<page>
,则会看到<Response><page>1</page>...
。如果您的XML数据包含1 of 1
,您会看到<Response><page>0</page>...
。
答案 1 :(得分:0)
我无法看到对Oleg的最新更新和max()的使用产生任何积极影响,因为在我的使用环境中,代码并未经过这一部分。 但是,源代码中还有另一个ts.p.lastpage = ...的实例。
ts.p.lastpage = lp === undefined? 1:lp;
替换为:
ts.p.lastpage = lp === undefined || lp === 0? 1:lp;
这对我有用。
