ExtJS：在属性列表后丢失}但我没有看到任何代码错误

Question

load failed -- arguments: [Object api=Object, Object request=Object reader=Object scope=Object, Object tId=0 status=200 statusText=OK, SyntaxError: missing } after property list message=missing } after property list]

I got that error by adding an exception to my store but don't see any real error in my code...maybe another set of eyes will help.

php:

 case 'messages':
                    if(isset($_SESSION['id'])){
            $stmt = $dbh->prepare("Select ID, ReceivedAt, Message from SystemEvents Limit 100");
                            $stmt->execute();

            while($tmp = $stmt->fetch()){
                $y .= '{"ID":"'.$tmp['ID'].'","ReceivedAt":"'.$tmp['ReceivedAt'].'","Message":"'.$tmp['Message'].'"},';
            }
            $y = trim($y,',');
            if(isset($_REQUEST['callback'])){
                echo $_REQUEST['callback'].'({"dates":['.$y.']});';
            }else{
                echo '{"dates":['.$y.']}';
            }
        }else{
            if(isset($_REQUEST['callback'])){
                                    echo $_REQUEST['callback'].'({success: false, data{"error_title": "Error", "errormsg": "Cannot display dates"}})';
                            }
                            else{
                                    echo '{success: false, data{"error_title": "Error", "errormsg": "Cannot display dates"}}';
                            }
                    }
            break;

extjs:

Ext.onReady(function(){

var logStore = new Ext.data.JsonStore({
    autoLoad: true,
    url: 'inc/interface/config.php?list=messages',
    root: 'dates',
    idProperty: 'ID',
    fields: ['ID', 'ReceivedAt', 'Message'],
    listeners: {
                loadexception: function() {
                    console.log('load failed -- arguments: %o', arguments);
                }
        }
}); 

var dateStore = new Ext.data.JsonStore({
    autoLoad: true,
    url: 'inc/interface/config.php?list=date_options',
    root: 'dates',
    idProperty: 'ID',
    fields: ['ID', 'ReceivedAt'],
    listeners: {
                loadexception: function() {
                    console.log('load failed -- arguments: %o', arguments);
                }
        }
});

var dateSelect = new Ext.form.DateField({
    fieldLabel: 'Pick a date',
    width: 190,
    align: 'center',
    frame: true
});

var dateCombo = new Ext.form.ComboBox({
    store: dateStore,
    mode: 'local',
    valueField: 'ID',
    displayField: 'ReceivedAt',
    editable: false,
    emptyText: 'Select a Date',
    width: 250,
    listeners:{
        activate: function(){
            dateStore.reload();
        }
    }
});

var searchField = new Ext.form.TextField({
    fieldLabel: 'Search Criteria',
    emptyText: 'Search....',
    width: 190, 
    frame: true

});

var searchButton = new Ext.Button({
    text: 'Search',
});

var clearButton = new Ext.Button({
    text: 'Clear',
    tooltip: 'Clears all your search data'
});

var searchPanel = new Ext.Panel({
    layout: 'form',
    region: 'east',
    width: 300,
    collapsible: true,
    alignButton: 'right',
    title: "Search Panel",
    items: [dateSelect, dateCombo, searchField],
    buttons: [clearButton, searchButton]
});


var logGrid = new Ext.grid.GridPanel({
    region: 'center',
    store: logStore,
    colModel: new Ext.grid.ColumnModel({
        columns: [{
            id: 'received',
            header: 'Received',
            dataIndex: 'ReceivedAt',
            width: 250
        },{
            id: 'message',
            header: 'Logs',
            dataIndex: 'Message',
            width: 750
        }]
    }),
});


var mainViewport = new Ext.Viewport({
    layout: 'border',
    items: [logGrid, searchPanel]
});

});

I don't think posting the rest of my php would be relevant since it all works but hopefully someone can spot something that my bad eyes cannot.

Answer 1

I see an extra comma here:

var searchButton = new Ext.Button({
    text: 'Search',
});

Also on the LogGrid. That might be it

EDIT: The response sent back from PHP does not look like it will be valid JSON if there is an error data{"error_title" is wrong, should be data:{"error_titel"

You really should look at building objects/arrays in PHP and echo these using json_encode instead of building JSON manually.
