Beginners extjs, want to read a local json files to the grid, but how to try all not line, form displayed but countless according to
Code:
The function mess () {
Ext. Define (' User '{
The extend: 'Ext data. The Model',
Fields: [" xh jg_num ", ""," jg_mc "]
});
Var mystore=Ext create (' Ext. Data. Store ', {
Model: 'User',
Proxy: {

});
Var grid=new Ext grid. GridPanel ({
Title: "the GRid form test,"
Width: 800,
Height: 300,
Store: mystore,
ColumnLine: true,
RenderTo: Ext getBody (),
The columns: [{
Header: "serial number", dadaIndex: xh},
{the header: "institutions", dataIndex: "jg_num"},
{the header: "name", dataIndex: "jg_mc", width: 300},
//height: 200,
Tbar: [
{xtype: 'textfield, name: "name"},
{text: 'query', name:} 'select', '-'

Did you release? Don't wait for its core with chrome browser, no allow access to a local file, but did not release sites don't use url: '/ js/yd_sf json ',

The path to relative path.. And/or js/XXX. Json to locate the path

Release site check server adds json file mime mapping: no, no is 404, does not support json file, such as iis 6 to the json files is not supported by default, the need to add 4 mime
