[Ext JS] Sorting by IP adress

[Stan Pak]

I want to sort my grid by IP adress like this
192.168.1.3
192.168.1.4
192.168.1.200

but, It's working like this
192.168.1.200
192.168.1.3
192.168.1.4

How can I sort the grid by IP adress correctly?

This is my code.

<script type="text/javascript">
Ext.onReady(function(){
	var store = new Ext.data.JsonStore({
		url: 'mainDataCollector.action',
		root: 'printerInfo',
		idProperty: 'ip',
		totalProperty: 'count',
		fields: ['ip', 'modelName', 'stateText', 'groupName'],
		remoteSort: true,
		sortInfo: { field: "groupName", direction: "ASC" }
	});

	var myPageSize = 20;
	var grid = new Ext.grid.GridPanel({
		renderTo: Ext.getBody(),
		frame:true,
		title: 'SH',
		height:530,
		width:500,
		loadMask: true,
		store: store,
		columns: [
			{header: "IP", dataIndex: 'ip', sortable: true},
			{header: "ModelName", dataIndex: 'modelName', sortable: true},
			{header: "StateText", dataIndex: 'stateText', sortable: true},
			{header: "GroupName", dataIndex: 'groupName', sortable: true}
		],
		bbar: new Ext.PagingToolbar({
			pageSize: myPageSize,
			store: store
		})
	});
	store.load({ params: { start: 0, limit: myPageSize} });
});
</script>

Thank you.

To my knowledge there are few, if any, members of JavaRanch using ExtJS. It's not particularly well regarded in the industry.

You might have better luck at the ExtJS Forums, or (if you have a choice) picking a more widely-used library.
