无法使用 sorttype 函数对 jqGrid 列进行排序
Unable to sort jqGrid column with sorttype function
正在尝试使用自定义排序对网格进行排序。我正在构建带有动态列和数据的 jqgrid。除了对其中一列进行排序外,一切都很好。我正在使用 javax.json 构建 json 并且我正在使用 jqgrid 4.7.0。这里是网格代码:
var resultsGrid = $("#resultsGrid");
var url = "grid/GridDataController?action=runSearch&searchText="+getSearchText()+"&_ts"+$.now();
var csvUrl = "grid/GridDataController?action=downloadCsv&_ts"+$.now();
var gridPagerId="#resultsPager";
var drawSearchResultsGrid = function(colNames,colModel,data) {
resultsGrid.disableSelection(); //disales highlioghting cells outside selection like ghosting.
resultsGrid.jqGrid({
url: url,
datatype: 'jsonstring',
loadonce: true,
mtype: "GET",
height: 300,
width: 700,
colNames: colNames,
colModel: colModel,
datastr : data,
rowNum: 100000,
sortname: "invid",
sortorder: "asc",
rownumbers: true,
viewrecords: true,
pager: gridPagerId,
pginput : false,
pgbuttons : false,
viewrecords : false,
gridview: true,
autoencode: true,
onSelectRow : function(id) {
logMessage("row selected ["+id+"]");
},
loadComplete: function(data) {
logMessage("load completed");
},
ondblClickRow : function(rowid) {
logMessage("Double clicked");
$(escapeColon("#contentForm:viewPropertiesButton")).click();
}
});
// Set navigator with search enabled.
resultsGrid.jqGrid('navGrid',gridPagerId,{add:false,edit:false,del:false,search:false,refresh:false});
// add custom button to export the data to excel
resultsGrid.jqGrid('navButtonAdd',gridPagerId,{
caption:"Export",
onClickButton : function () {
resultsGrid.jqGrid('excelExport',{"url":csvUrl});
}
});
}; //end drawResultGrid function
//get grid config...
$.ajax({
type: "GET",
url: url,
data: "",
dataType: "json",
success: function(response)
{
if (response.result == "0")
{
logMessage("Drawing results grid...");
drawSearchResultsGrid(response.colNames,response.colModel,response.data);
resizeGrid();
logMessage("Results grid drawing done.");
}
else
{
logMessage("Error : " + response.message);
alert(response.message);
}
},
error: function(x, e)
{
alert(x.readyState + " "+ x.status +" "+ e.msg);
}
});
这是我的动态 colModel:
{
"result":"0",
"message":"",
"data":{
"records":18,
"total":1,
"page":"1",
"rows":[ ]
},
"colNames":[
"IP Address/Cidr",
"Name",
"IP Decimal",
"Cidr"
],
"colModel":[
{
"name":"adressCidr",
"width":50,
"sortable":true,
"hidden":false,
"sorttype":"function (cellValue,rowObject) { console.log('sorting by ['+rowObject.ipDecimal+']'); return parseInt(rowObject.ipDecimal,10);}"
},
{
"name":"name",
"width":50,
"sortable":true,
"hidden":false
},
{
"name":"ipDecimal",
"width":50,
"sortable":true,
"hidden":false,
"sorttype":"int"
},
{
"name":"cidr",
"width":0,
"sortable":false,
"hidden":true
}
]
}
ipDecimal 是一个隐藏列,但我出于测试目的显示它。要求是第一列 'addressCidr' 是一个字符串列,但我想使用隐藏的 ipDecimal 列对其进行排序。该函数既不显示 console.log 消息也不正确排序。但是,如果我通过单击它的 header 将 ipDecimal 排序为 'int',它工作正常。我唯一能想到的是 sorttype 函数本身的双引号。如果您在这里看到任何其他问题,或者解决此案例的最佳方法是什么,请告诉我。这是我构建 json 函数的片段:
private JsonObjectBuilder createColumn(JsonBuilderFactory factory,
String name,int width,boolean sortable,boolean hidden,boolean sorttype)
{
JsonObjectBuilder column =this.createColumn(factory, name, width, sortable, hidden);
StringBuilder fnBuilder = new StringBuilder("");
//this is not generic but can easily be made one :(
fnBuilder.append("function (cellValue,rowObject) {");
fnBuilder.append(" console.log('sorting by ['+rowObject.ipDecimal+']');");
fnBuilder.append(" return parseInt(rowObject.ipDecimal,10);");
fnBuilder.append("}");
column.add("sorttype", fnBuilder.toString()); // this works, not sure why above function does not work :(
return column;
}
private JsonObjectBuilder createColumn(JsonBuilderFactory factory,
String name,int width,boolean sortable,boolean hidden)
{
JsonObjectBuilder column;
column = factory.createObjectBuilder();
column.add("name", name);
column.add("width", width);
column.add("sortable", sortable);
column.add("hidden", hidden);
return column;
}
我用来测试的数据是:
IpAddressCidr ipDecimal
5.1.0.0/24--83951616
5.1.1.0/24--83951872
5.1.2.0/24--83952128
5.1.3.0/24--83952384
5.1.4.0/24--83952640
5.3.0.0/24--84082688
5.9.2.0/24--84476416
6.0.0.0/24--100663296
6.0.1.0/24--100663552
6.0.2.0/24--100663808
6.0.3.0/24--100664064
6.0.4.0/24--100664320
6.0.5.0/24--100664576
7.1.0.0/24--117506048
7.1.1.0/24--117506304
7.1.2.0/24--117506560
7.1.3.0/24--117506816
198.186.198.0/24--3334129152
但这是我看到的
IP 198.186.198.0 应该出现在顶部,因为它具有最高的 ipDecimal,但它被推到了底部。
添加更多测试信息。如果我删除封闭的双引号,排序工作正常,但不是。
以下作品:
{ name: "adressCidr", width:50, sortable: true,
sorttype: function (cellValue,rowObject) { console.log('sorting by ['+rowObject.ipDecimal+']');return parseInt(rowObject.ipDecimal,10);}},
以下没有:
{ name: "adressCidr", width:50, sortable: true,
sorttype: "function (cellValue,rowObject) { console.log('sorting by ['+rowObject.ipDecimal+']');return parseInt(rowObject.ipDecimal,10);}"},
问题的原因是 sorttype
的用法,您将其定义为字符串而不是函数:
{
"name":"adressCidr",
"width":50,
"sortable":true,
"hidden":false,
"sorttype":"function (cellValue,rowObject) { console.log('sorting by ['+rowObject.ipDecimal+']'); return parseInt(rowObject.ipDecimal,10);}"
}
您使用 jqGrid 4.7,其中包含我建议的新功能(参见 here)。所以你可以包含像
这样的代码
$.extend($.jgrid, {
cmTemplate: {
myIpAddress: {
sorttype: function (cellValue, rowObject) {
console.log('sorting by [' + rowObject.ipDecimal + ']');
return parseInt(rowObject.ipDecimal, 10);
},
width: 50
}
}
});
现在可以把服务器返回的数据改成
{
"name":"adressCidr",
"sortable":true,
"hidden":false,
"template":"myIpAddress"
}
