View Full Version : loading error of paging grid

1 Jul 2007, 3:04 AM

var ds = new Ext.data.Store({
proxy: new Ext.data.ScriptTagProxy({
url: 'EchoJson.json'

reader: new Ext.data.JsonReader({
root: 'records',
totalProperty: 'totalCount',
id: 'id'
}, [
{name: 'name', mapping: 'name'},
{name: 'pwd', mapping: 'pwd'},
{name: 'lastip', mapping: 'lastip'},
{name: 'lastLogin', mapping: 'lastLogin'}

remoteSort: true
ds.setDefaultSort('name', 'asc');

var cm = new Ext.grid.ColumnModel([{
id: 'id',
header: "id",
dataIndex: 'id',
width: 0,
hidden: true
header: "name",
dataIndex: 'name',
width: 70
header: "pass word",
dataIndex: 'pwd',
width: 170,
align: 'right'
header: "last login ip",
dataIndex: 'lastip',
width: 170,
align: 'right'
header: "last login",
dataIndex: 'lastLogin',
width: 100

cm.defaultSortable = true;

var grid = new Ext.grid.Grid('list-div', {
ds: ds,
cm: cm,
selModel: new Ext.grid.RowSelectionModel({singleSelect:true}),
loadMask: true

var rz = new Ext.Resizable('list-div', {
handles: 's'
rz.on('resize', grid.autoSize, grid);


var gridFoot = grid.getView().getFooterPanel(true);

var paging = new Ext.PagingToolbar(gridFoot, ds, {
pageSize: 25,
displayInfo: true

ds.load({params:{start:0, limit:25}});

The data url returns

{"lastip":"","name":"sa","lastLogin":"2007-05-01 00:00:00.0","id":"sa","pwd":"123"},

When open the page, the grid shows, but it keeps loading data.
Is my json data returns in error format?

The problem I posted is like this.

I follow the page grid example of ext docs,
I click the www.yui-ext.com/forum2/topics-remote.php url and
save the json data into one text file 'json.txt',
then copy the json.txt to the same directory of paging.html and
modify url of ScriptTagProxy from "topics-remote.php" to "json.txt" in the paging.js file.

When I open the new paging.html, It shows the grid, but loading dialog pop out and
can't not really bring data into grid.

Why are you using ScriptTagProxy rather than HtttpProxy? What is that url - is it valid? Look at firebug - is the request coming back?

thank you for your quick reply.

I just follow the example of ext doc where ScriptTagProxy is used.

Now I use HttpProxy, it works.

The url is my java serverlet which response json data with remote sorting and pagination.
