jqGrid : searchrules in single Field searching - jqgrid

Question

I'm trying to validate the search field for integer data alone but unfortunately am unable to do so. I have tried all possible solutions like searchrules:{required:true,integer=true} etc..
But none of them proves fruitful.
I basically launch the search dialog with the field and without inputting any data, am hitting on the 'Find' button. As per the above options, i believe a validation message should be shown to the user asking him to enter a value in the field before hitting find.
[UPDATED] - Code Snippet
var grid = $("#list");
grid.jqGrid({
url:'/index.jsp',
datatype: 'json',
mtype: 'POST',
colNames:['Name','Age', 'Address'],
colModel :[
{name:'name', index:'name', width:55,search:true },
{name:'age', index:'age',
width:90,editable:true,search:true, stype:'text',
searchrules:{required:true,integer:true}},
{name:'address', index:'address', width:80,
align:'right', editable: true,search:false }
],
pager: '#pager',
jsonReader : {
root:"address",
page: "page",
total: "total",
records: "records",
repeatitems: false
},
rowNum:10,
rowList:[10,20,30],
sortname: 'name',
sortorder: 'desc',
viewrecords: true,
gridview: true,
autowidth: true,
toppager: true,
loadtext: "Loading records.....",
caption: 'Test Grid',
gridComplete: function(){
}
});
**grid**.jqGrid('navGrid','#pager',
{view:true,edit:true,add:true,del:true,refresh:true,
refreshtext:'Refresh',addtext:'Add',
edittext:'Edit',cloneToTop:true,
edittitle: "Edit selected row"},
{},{},{},
{caption: "Search The Grid",Find: "Find Value",Reset: "Reset"},
{});
[Updated] : Am not able to make the searchrules properly work for the single/advanced searching modes.
[Updated] : Even the 'Validation in Search' in
jqGrid Demo is not working for searchrules.

Answer 1

The reason of described problem is a bug in jqGrid. The line
ret = $.jgrid.checkValues(val, -1, null, colModelItem.searchrules, colModelItem.label);
initialize the third parameter of $.jgrid.checkValues to null, but the last version of checkValues implementation started (see the line) with
var cm = g.p.colModel;
but g is initialized to null. The last modification which generates the error was based on my suggestion, but I don't wrote the part of the code.
One can solve the problem in different way. I would suggest to modify the line where $.jgrid.checkValues will be called with null parameter to the following
ret = $.jgrid.checkValues(val, -1, {p: {colModel: p.columns}}, colModelItem.searchrules, colModelItem.label);
Additionally, to be sure, I would suggest to modify one more line
if(!nm) { nm = g.p.colNames[valref]; }
to
if(!nm) { nm = g.p.colNames != null ? g.p.colNames[valref] : cm.label; }
The fixed version of jquery.jqGrid.src.js one can get here. I will post my bug report with the same suggestions later ti trirand.
