I have a jqGrid that is filled by a JSON request, the thing is that the request back to the server in base64 encoded data and I need to decode the data before assign it to the grid.
Basically I need something like this:
$( "#grid" ).jqGrid( {
datatype: "json",
colNames: ["id", "Num", "Name", "Code"],
colModel: [
{ name: "id", index: "id", width: 30, sortable: true, resizable: false },
{ name: "num", index: "num", width: 150, sortable: true, resizable: false },
{ name: "name", index: "name", width: 250, sortable: true, resizable: false },
{ name: "code", index: "code", width: 150, sortable: true, resizable: false },
],
multiselect: true,
width: "760",
height: "100%",
heightMetric: "%",
shrinkToFit: false,
rowNum: 20,
rowList: [20,30,60],
pager: "#pager",
sortname: "id",
viewrecords: true,
sortorder: "asc",
headertitles : true,
caption: "Loading...",
beforeProcessing: function(data){
data = decompress(data); // Like this
}
})
The callback function beforeProcessing is the correct place where you can implement all what you need. The exact implementation depends on the format of the data returned by the server. If one uses datatype: "json" then the data returned from the server are typically an object which is serializes as JSON string. jqGrid uses internally jQuery.ajax which automatically decode the JSON string and convert it back to object. So the input data parameter of beforeProcessing callback is the object returned from the server. If you don't use any additional jsonReader option of jqGrid then jqGrid wait the input data in the standard format described here. So you need just fill the expected properties of data object (rows, page, total and records) based on the input data returned from the server. You don't posted any example of the data returned from the server, so I could give you no more detailed examples.
I want to get values of 2 column in a javascript function when a row is selected(clicked) in jqgrid table.what i want is add a javascript onclick event on each row and javascript function gets the values of col3 and col4 of selected row.my code is
jQuery("#table1").jqGrid({
url:'petstore.do?q=1&Path='+path,
datatype: "json",
colNames:['col1','col2','col3','col4'],
colModel:[
{name:'col1',index:'col1',sortable:true,width:250},
{name:'col2',index:'col2',sortable:true,width:100},
{name:'col3',index:'col3', sortable:true,width:100},
{name:'col4',index:'col4', sortable:true},
],
multiselect: false,
paging: true,
rowNum:10,
rowList:[10,20,30],
pager: $("#pager")
}).navGrid('#pager',{edit:false,add:false,del:false});
can any body help me out from this ?
You should handle the onSelectRow event (which is raised immediately after the row has been clicked) and then you can use getRowData method in order to get selected row data as an array:
$('#table1').jqGrid({
url: 'petstore.do?q=1&Path='+path,
datatype: 'json',
colNames: ['col1', 'col2', 'col3', 'col4'],
colModel: [
{name:'col1', index:'col1', sortable:true, width:250},
{name:'col2', index:'col2', sortable:true, width:100},
{name:'col3', index:'col3', sortable:true, width:100},
{name:'col4', index:'col4', sortable:true}
],
multiselect: false,
paging: true,
rowNum: 10,
rowList: [10,20,30],
pager: $('#pager'),
onSelectRow: function(rowId){
var rowData = $('#table1').jqGrid('getRowData', rowId);
//You can access the desired columns like this --> rowData['col3']
...
}
}).navGrid('#pager', {edit:false, add:false, del:false});
This should get you what you want.
Here append similar questions but I cannot find answer to my one:
In html is
table id= grid and div id=pager:
Also I have mine js code:
var myGrid = $("#grid").jqGrid({
url: _options.gridFetch,
datatype: "json",
colModel:[
{name:'id',index:'id', width:55},
{name:'name',index:'name', width:555, editable:true},
{name:'is_promoted',index:'is_promoted', width:165, editable:true, formatter: $.adminCategoryEntries._boolFormatter, edittype: 'select', editoptions:{value:"1:Yes;0:No"}},
{name:'is_in_shop',index:'is_in_shop', width:165, editable:true, formatter: $.adminCategoryEntries._boolFormatter, edittype: 'select', editoptions:{value:"1:Yes;0:No"}},
{name:'actions', formatter:'actions', width: 85, formatoptions:{keys:true}},
],
pager: '#pager',
jsonReader : { repeatitems: false } ,
rowNum: 10,
rowList: [10, 20, 500],
viewrecords: true,
autowidth: true,
sortname: 'id',
sortorder: 'desc'
});
myGrid.jqGrid('navGrid','#pager',{edit:false,add:false,del:false,search:false});
I've use code from other stackoverflow tutorial.
And here is my issue: If I try to change number of showed rows in my navigator I can see all stored data (86 rows) but if I set rows to i.e 10 (value less than rows number)per page I always see in my navigator:
page 1 of 5
and I cannot switch it to another it always stays on first
json info:
>page: 1
>records: "86"
>rows: [{id:3, name:Ulkofilee/Naudanliha, is_promoted:1, is_in_shop:1},…]
>total: 5
thanks in advance

Are you getting the data from a server method you can control? It's somewhat cryptic, but the data coming from your _options.gridFetch needs to have a property named "total" defined that specifies the current page that should be viewed.
I'm having a problem that I can't sort it out.
Please take a look at this image first
As you can see, I have been able to request the JSON data from server. The pager shows that there were 4 records. But the records didn't shows in the table.
This is my javascript code
jQuery("#pickFlex66").jqGrid({
url: root + '<?=$mod?>' + '/listpicker',
datatype: "json",
altRows: true,
mtype: 'POST',
colNames:['Code','Company Name'],
colModel:[
{name:'company_code',index:'company_code', width:100},
{name:'company_name',index:'company_name', width:100}
],
rowNum:10,
width: 540,
height: 310,
rowList:[10,20,30],
pager: '#pagerFlex66',
sortname: 'company_code',
shrinkToFit: false,
viewrecords: true,
sortorder: "desc",
caption:"<?=lang("users_title")?>",
onSelectRow: function(id){
}
});
jQuery("#pickFlex66").jqGrid('navGrid','#pagerFlex66',{edit:false,add:false,del:false,search:false});
And here is my JSON data
{
"page": "1",
"total": 0,
"records": "4",
"rows": [{"id":"5","cell":["55-123","123"]},{"id":"3","cell":["123","IBM"]},{"id":"2","cell":["00000","BDO"]},{"id":"1","cell":["000-00","IT GROUP Inc "]}]
}
Is there a mistake in my javascript? Or maybe in my JSON data?
I agree with Briguy37 that the value "total": 0 is strange and of cause incorrect. Nevertheless jqGrid should do display all data.
I suppose that you have the problem in the part of your code which you not posted here. How you can see from the demo the code which you posted can do read and display the JSON data.
Here's a couple issues...haven't figured out why your results aren't getting populated yet, though:
Total in your returned JSON should be the number of pages. Because it is set to 0, that is why it is displaying 0. Also, you'll probably want to return rowCount as 10 in case you change the number of results per page.
You are missing a json reader, I had the exact same problem.
$("#list").jqGrid({
url : "my-json-table-action' />",
datatype: 'json',
jsonReader: {
root: 'gridModel',
id: 'idTT',
repeatitems: false,
},
resize: false,
hidegrid: false,
data: 'trabajosTerminales',
mtype: 'POST',
height: 'auto',
colNames:['No. de Registro', 'Título', 'Tipo', 'Periodo'],
colModel :[
{name:'numRegistro', index:'titulo', search: 'true', stype:'text', align:'center' searchrules:{required:true}, width:100 },
{name:'titulo', key:'true', index:'titulo', search: 'true', stype:'text', searchrules:{required:true}, width:800 },
{name:'tipo', key:'true', index:'tipo', search: 'true', stype:'text',align:'center', searchrules:{required:true}, width:100 },
{name:'periodo', key:'true', index:'titulo', search: 'true', stype:'text', searchrules:{required:true}, width:100 },
],
pager: '#pager',
rowNum:10,
rowList:[10,20,30],
viewrecords: true,
gridview: true,
caption: 'Trabajos Terminales dirigidos',
});
jQuery("#list").navGrid('#pager',{edit:false,add:false,del:false});
});
Where the root element is the array that contains your data, in this case I'm returning my data in an array called 'gridModel', the id is not necessary. But you have to make sure to set the root element right, in your case it's called 'rows' instead 'gridModel'.
I am facing problem with pagination in jqgrid with array data having 18 records, but the records are not displaying in pages even I specified pagination:true,pager:jQuery('#pager1'). Can you please help me to implement pagination instead of scrolling.

for(var i=0;i<=mydata.length;i++)
jQuery("#list4").addRowData(i+1,mydata[i]);
You main problem is you should reset rowNum after the adding the large number of rows. The line
jQuery("#list4").setGridParam({ rowNum: 10 }).trigger("reloadGrid");
at the end of your code will fix the problem. I recommend you to add the line
jQuery("#list4").jqGrid('navGrid','#pager1',{edit:false,add:false,del:false});
directly after the definition of the jqGrid. You will then have not only data paging, but also data filtering (searching) and refresh (reset filter).
Some more small remarks:
in the definition of the mydata array you should remove ',' before ']'.
in the for loop you should use i<mydata.length instead of i<=mydata.length.
you should remove from the definition of jqGrid following parameters which are either non existent (like pagination) or have no sense in the context (like loadonce: true): pagination, page, loadonce, totalpages, totalrecords, showpage, imgpath.
You receive the best results if you constructs jqGrid with respect of data: myData parameter, or set all data from mydata at once (see description of addRowData method in http://www.trirand.com/jqgridwiki/doku.php?id=wiki:retrieving_data#array_data).
Oleg is correct.
Adding jQuery("#list4").setGridParam({ rowNum: 10 }).trigger("reloadGrid");
works.
Although it might not work if formatter property is set where the rowObject values will be undefined.(if they are used)
Therefore make sure in your formatter method u always check for their availability.
e.g.
function getFormattedFileName(cellvalue, options, rowObject) {
if(!rowObject.fileName) {// this is due to ...trigger("reloadGrid");
return cellvalue; // the value is already formatted, let's just return it
}
return rowObject.fileName.trim();
}
