How to obtain id property in custom formatter - jqgrid

Question

My server provides the following json string:
{
"total":3,
"page":1,
"records":52,
"rows":[
{"cell":[
"6789",
"Veridien Dynamics",
"ver01",
"Description of Site: ver01",
"1986a594-bb12-4a4a-a70b-4b85251fd268",
"UKSODMBHANU01",
6440],
"id":120}
......
]
}
In my grid, I would like to have a link for each row. The link is built using custom formatter. The url for the link needs to include the id (e.g. 120). I cannot obtain the value of id from cellvalue, options, nor the rowObject in my custom formatter. Since id is not part of the 'cell', I don't know how to obtain this value to construct the url.
Following is part of my grid definition :
$("#list").jqGrid({
url:'http://mydomain:8080/myserver/api/v1/data-grid.json',
loadBeforeSend: function(xhr) {
xhr.setRequestHeader("Authorization",'Basic xxxxxxxxxxxxxxxxxxxxxxxxx');
return xhr;
},
datatype: "json",
jsonReader : {
root: "rows",
page: "page",
total: "total",
records: "records",
repeatitems: true,
cell: "cell",
id: "id"
},
colNames:['Customer ID','Customer','Site ID','Site', 'Server ID','Server Name',
'XML Size','id'],
colModel :[
{name:'customerID',editable:false},
{name:'customerName',editable:false},
{name:'siteID',editable:false,width:60, align:'center'},
{name:'siteDescription',editable:false,align:'center'},
{name:'serverID',editable:false,width:150,align:'right'},
{name:'serverName',editable:false, width:150,align:'right'},
{name:'xmlSize',editable:false, align:'right'},
{name:'id', index:'id', editable:false,
align:'center',formatter:that.xmlLinkFormatter},
],
......
}
Following is my xmlLinkFormatter, everything works fine if I hard code the id value here to be part of the targetURL.
xmlLinkFormatter:function(cellvalue, options, rowObject){
var targetURL = "http://mydomain:8080/myServer/data/showXml/"+
IwantIDValue here;
var link = "<a href='javascript: void(0)' onclick=\"window.open('" +
targetURL + "');\">View XML</a>";
return link;
}

I suggest you to use unobtrusive JavaScript to build the link. So the custom formatter can be very easy:
xmlLinkFormatter:function(cellvalue, options, rowObject){
return "<a href='#'>View XML</a>";
}
now the contain of the 'id' column will be the same as in your example. To make 'onclick' binding I suggest to use jQuery.click.
The way how one can implement unobtrusive JavaScript in jqGrid I described here and here. So I will use almost the same way and will use the same simple helper function getColumnIndexByName:
loadComplete: function() {
var i=getColumnIndexByName(myGrid,'id');
// nth-child need 1-based index so we use (i+1) below
$("tbody > tr.jqgrow > td:nth-child("+(i+1)+") > a",myGrid[0]).click(function(e){
var tr=$(e.target,myGrid[0].rows).closest("tr.jqgrow");
//alert("clicked the row with the id='"+tr[0].id+"'");
e.preventDefault();
window.open("http://mydomain:8080/myServer/data/showXml/"+
encodeURIComponent(tr[0].id));
});
}
(the variable myGrid here is defined as var myGrid=$("#list");)
How you can verify in the live demo here, the approach works.
