在jqgrid中，rowobject值在第一页中未定义，rowObject值在下一页中返回

Question

In jqgrid-4.8 I am getting rowObject value as undefined in first page and receiving values in next pages if I used rowObject.name. if I used rowObject[0] then rowObject values as getting from cells in first page but not in subsequent pages. plz help to solve this issue.

 {name:'snp',index:'snp', width:100, align:"center"},
 {name:'chr',index:'chr', width:100, align:"center"},
 {name:'pos',index:'pos', width:100, align:"center"},
 {name:'calls',index:'calls',width:120,align:"center",sortable:false,formatter:function(cellvalue, options, rowObject){ return '<a href="http://localhost/var/sub1.php?id='+rowObject.snp+'&chr='+rowObject.chr+'&pos='+rowObject.pos+'" target="_blank"><font color="0000FF">view</a>';} }

If I use rowObject[0] & rowObject[1] is also not fully functional, it is functional in first page, not is next pages. it is showing cell values as undefined

The problem, which you described is old known. Old version of jqGrid makes difficult to write custom formatter where you have to access data from another column if you use array of items as input data. Simple trick described in the old answer allows to write the corresponding code. Instead of $.isArray one should better use Array.isArray method.

If you use free jqGrid then you can solve the problem more easier. I don't changed the format of the 3-d parameter (rowObject) of custom formatter, but I added rowData property to options option with named data. Thus you can use the following code in free jqGrid:

formatter: function (cellvalue, options) {
    var item = options.rowData;
    return '<a href="http://localhost/var/sub1.php?id=' + 
        item.snp + '&chr=' + item.chr + '&pos=' + item.pos +
        '" target="_blank"><font color="0000FF">view</a>';
}

Additionally I would strictly recommend you to use current version of free jqGrid (4.15.4 or probably 4.15.5) instead of retro version 4.8, which is not more supported.
