height属性导致停止脚本

Question

I am using a Panel to show the scrollable grid. My code is

var resultsPanel = Ext.create('Ext.panel.Panel', {
height:140,
items: companyView,
renderTo: 'addTable'+i,
layout: 'fit'
});

var checkbox = new Ext.selection.CheckboxModel();
companyView = Ext.create('Ext.grid.Panel', {
    title:'',
    selModel: checkbox,
    id:'companylist'+i,
    store: store1,
    multiSelect: true,
    viewConfig: { emptyText: 'No data to display'},
    columns:[
                {header: 'Type', width: 80, flex: 1, dataIndex: 'type',
                renderer: sample},
                {header: '%', width: 30, flex: 1, dataIndex: 'per'},
                {header: 'Name', width: 30, flex: 1, dataIndex: 'name',renderer:functOwnerNameCmp},
                {header: 'O.%', width: 50, flex: 1, dataIndex: 'owner'},
                {header: 'Role', width: 30, flex: 1, dataIndex: 'role'},
                {header: 'Gender', width: 50, flex: 1, dataIndex: 'gender'}
            ],
    tbar  : [
                {
                    text: 'Delete Selected',
                    margins: '0 0 0 290',
                    handler: function() 
                    {
                        rowsSelected = companyView.getSelectionModel().getSelection();
                        if(rowsSelected.length==0) {
                            Ext.Msg.alert(' ', 'Please select one record');
                        } else {
                            Ext.MessageBox.confirm(' ', 'Are you sure you want to remove Person?',confirmRemoveAffCmpRec);
                    }
                }
            }    
            ]
        });

If I don't use the height attribute, the script is ok but if I use height in this attribute the script gets stopped and the message is shown by the browser for eg in Mozilla-
Unresponsive Script
A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

What can be the problem?

Answer 1

The code above is Ok, I just needed to specify width also whenever I used the height attribute.
