0.82 Ext.setup() should check for meta tags before it adds them.

[watrboy00]

I've made comments in red where needed...

Ext.setup = function(config) {    
    if (Ext.isObject(config)) {
        var appendString ='',
            viewport = Ext.get(document.createElement('meta')),
            app = Ext.get(document.createElement('meta')),
            statusBar = Ext.get(document.createElement('meta')),
            startupScreen = Ext.get(document.createElement('link')),
            appIcon = Ext.get(document.createElement('link'));

        //does user-scalable=no, user-scalable=0 translate different on different platforms?
        viewport.set({
            name: 'viewport',
            content: 'width=device-width, user-scalable=no, initial-scale=1.0; maximum-scale=1.0; user-scalable=0;'
        });

        if (config.fullscreen !== false) {
            app.set({
                name: 'apple-mobile-web-app-capable',
                content: 'yes'
            });
            
            if (Ext.isString(config.statusBarStyle)) {
                statusBar.set({
                    name: 'apple-mobile-web-app-status-bar-style',
                    content: config.statusBarStyle
                })
            }
        }

        if (Ext.isString(config.tabletStartupScreen) && Ext.platform.isTablet) {
            startupScreen.set({
                rel: 'apple-touch-startup-image',
                href: config.tabletStartupScreen
            });
        } else if (Ext.isString(config.phoneStartupScreen) && Ext.platform.isPhone) {
            startupScreen.set({
                rel: 'apple-touch-startup-image',
                href: config.phoneStartupScreen
            });
        }

        if (config.icon) {
            config.phoneIcon = config.tabletIcon = config.icon;
        }
        
        var precomposed = (config.glossOnIcon == false) ? '-precomposed' : '';
        if (Ext.isString(config.tabletIcon) && Ext.platform.isTablet) {
            appIcon.set({
                rel: 'apple-touch-icon' + precomposed,
                href: config.tabletIcon
            });
        } else if (Ext.isString(config.phoneIcon) && Ext.platform.isPhone) {
            appIcon.set({
                rel: 'apple-touch-icon' + precomposed,
                href: config.phoneIcon
            });
        }
        
        if (Ext.isArray(config.preloadImages)) {
            for (var i = config.preloadImages.length - 1; i >= 0; i--) {
                (new Image()).src = config.preloadImages[i];
            };
        }
        
        //I have an app that is already built that I am layering Touch on top of. Because of this I already have the meta viewport tag setup. With this block it duplicates the tag. Same *could* be said about the others.
        var attachTags = function(){
            var head = Ext.get(document.getElementsByTagName('head')[0]);
            head.appendChild(viewport);
            if (app.getAttribute('name')) head.appendChild(app);
            if (statusBar.getAttribute('name')) head.appendChild(statusBar);
            
            if (appIcon.getAttribute('href')) head.appendChild(appIcon);
            if (startupScreen.getAttribute('href')) head.appendChild(startupScreen);
        };

        if (Ext.platform.isAndroidOS) {
            attachTags();
        }
        else {
            Ext.onReady(attachTags);
        }
        
        if (Ext.isFunction(config.onReady)) {
            Ext.onReady(config.onReady, config.scope || window);
        }
    }
};

Good idea. Will look into doing this.

[TommyMaintz]

For now I have added an addMetaTags configuration option to setup. It defaults to true. Somehow looping over all meta tags and check for attributes felt a bit dirty.

[watrboy00]

I like. Def better than individual checks.

Tommy, any idea about the user-scalable = 0|no? Is it a requirement to have both? Like does 0 only work on iPhone|iPad and no works on Android or something like that?

[TommyMaintz]

No, that was a bug. Also the mixing of semicolons and commas was wrong. This is al
Fixed in the next release.

[watrboy00]

I believe they are suppose to be commas correct? and which one is correct the 0 or the no?

[TommyMaintz]

I think "no" is the correct one, and commas.
