lkritchey on Error during JQGrid load

Wed, 13 Oct 2010 18:10:59 +0300

I am creating a jqgrid that appears in a jquery modal window. It loads the grid successfully, but while loading the grid, it comes up with the error: Invalid argument. It pauses at a line in the jquery-1.4.2.min.js file ("{e.username?x.open(n,e.url,e.async,e.username,e.password):x.open(n,e.url,e.async);").

To create the grid, I call a webservice, which returns an object. I serialize the object, and parse it once it is returned to the webpage. Below is my code to set up the grid:

ItemOverview.prototype.itemGridView = function() {

$("itemGridView").jqGrid({

mytype: 'POST',

datatype: this.GetData(),

jsonReader: {

root: "root",

repeatitems: false,

id: "itemKey",

cell: ""

colNames: ['Item Key', 'Item', 'CAGE', 'Nomen'],

colModel: [

{name: 'itemKey', hidden: true, sortable: false},

{name: 'item', sortable: true},

{name: 'nomenclature', sortable: true}

pager: '#pageNavigation',

rowNum: 500,

…moreoptions…

});

}

Below is the code for GetData():

ItemOverview.prototype.GetData = function() {

data = this.txtItemNomen.val();

//Web service function - common function for all web pages

var ws = new WebService();

ws.RunFunction("GetItemJsonReader", data, $.proxy(this.GetItemsInList, this), $.proxy(this.Unsuccessful, this));

}

This code returns a JSON object with the following data (note that I have real data in the actual code with more than 2 records):

{"page:":"x","total":"x","records":x,"root":[{"col1":x,"col2":x,"col3":x},{"col1":y,"col2":y,"col3":y}]}

Below is the success function (GetItemsInList)

ItemOverview.prototype.GetItemsInList = function(jObject) {

var theGrid=jQuery("#itemGridView")[0];

theGrid.addJSONData(jObject);

}

Where GetItemJsonReader() is the webservice function name, this.GetItemsInList is the success function and this.Unsuccessful is the failed option

this.GetItemsInList code below:

ItemOverview.prototype.GetItemsInList = function(jObject) {

var theGrid=jQuery("#itemGridView")[0];

theGrid.addJSONData(jObject);

}

Below is the code to show the table in a jQuery modal window:

ItemOverview.prototype.Search_Click = function() {

$("#itemGridView").dialog(

{

modal: true,

close: $.proxy(this.DialogClosed, this),

closeText: "hide",

…More Options…

})

this.itemGridView();

$("#itemGridView").show();

}

Please note again that the data does load successfully – it just comes up with the Invalid argument error while the data is loading. Any help is very much appreciated…if any other code or information should be posted, please let me know.

Thanks,

Laura
