How to hide the source data generated pages

[llxchen]

I'm in the IE browser, use the View Source and found the data to see Store, this should be unsafe, is there any way to hide the data.

In the example: https://examples1.ext.net/Examples/G...ta/DataReader/
, View the source code as follows:

<![CDATA[
Ext.net.ResourceMgr.init({id:"ctl04",BLANK_IMAGE_U RL:"/extjs/resources/images/default/s-gif/ext.axd",aspForm:"ctl01",theme:"blue"});Ext.onRead y(function(){Ext.QuickTips.init();this.Store1=new Ext.ux.data.PagingStore({proxyId:"Store1",autoLoad :true,reader:new Ext.data.JsonReader({fields:[{name:"SupplierID"},{name:"CompanyName"},{name:"Co ntactName"},{name:"ContactTitle"}]}),directEventConfig:{},proxy:new Ext.data.PagingMemoryProxy([{"SupplierID":1,"CompanyName":"Exotic Liquids222","ContactName":"Charlotte Cooper","ContactTitle":"Purchasing Manager"},{"SupplierID":2,"CompanyName":"New Orleans Cajun Delights","ContactName":"Shelley Burke","ContactTitle":"Order Administrator"},{"SupplierID":3,"CompanyName":"Gra ndma Kelly's Homestead","ContactName":"Regina Murphy","ContactTitle":"Sales Representative"},{"SupplierID":4,"CompanyName":"To kyo Traders","ContactName":"Yoshi Nagase","ContactTitle":"Marketing Manager"},{"SupplierID":5,"CompanyName":"Cooperati va de Quesos 'Las Cabras'","ContactName":"Antonio del Valle Saavedra","ContactTitle":"89089Export Administrator"},{"SupplierID":6,"CompanyName":"May umi's Testing Data","ContactName":"Mayumi Ohno","ContactTitle":"Marketing Representative"},{"SupplierID":7,"CompanyName":"Pa vlova, Ltd.","ContactName":"Ian Devling","ContactTitle":"Marketing Manager"},{"SupplierID":8,"CompanyName":"Specialty Biscuits, Ltd.","ContactName":"Peter Wilson","ContactTitle":""},{"SupplierID":9,"Compan yName":"PB Knackebrod AB","ContactName":"Lars Peterson","ContactTitle":"Sales Agent"},{"SupplierID":10,"CompanyName":"Refrescos Americanas LTDA","ContactName":"Carlos Diaz","ContactTitle":"Marketing Manager"},{"SupplierID":11,"CompanyName":"Heli Su?waren GmbH & Co.

//]]>
</script>

Will the data like this: {"SupplierID": 62, "CompanyName": "dasdas", "ContactName": "", "ContactTitle": ""}
Can not display?

sorry, my English is bad, above content is to use Google Translate, please forgive me.

Can you explain what it is that you wish to protect against? A safe assumption is that anything sent to the browser can be known by the user. If your only goal is to make the data not human-readable from View Source, you could either have the store make its own separate load request or obfuscate it using base64 to encode the JSON on the server and then decode on the client before loading, but neither of these will protect the data from someone who knows how to use the browser's developer tools. Alternatively, if your concern is about the data being visible in transit, then you should be using HTTPS.

One option to "hide" the inline source is to set initScriptMode="Linked" within the <extnet> section of your Web.config.

<extnet initScriptMode="Linked" />

You can also set the value on the ResourceManager.

<ext:ResourceManager runat="server" InitScriptMode="Linked" />

Of course this doesn't actually "hide" the JavaScript source, which is always discoverable in a web app, but it does remove the source from being rendered inline on the Page.

Hope this helps.
