How to show property bag values of site collection in web part on landing page in sharepoint online - office 365?

Answer 1

You can use JavaScript Client object model to read the property bag values. Example:
function getWebProperty() {
var ctx = new SP.ClientContext.get_current();
var web = ctx.get_site().get_rootWeb();
this.props =  web.get_allProperties();
ctx.load(web);
ctx.load(this.props); //need to load the properties explicitly
ctx.executeQueryAsync(Function.createDelegate(this, gotProperty), Function.createDelegate(this, failedGettingProperty));
function gotProperty() {
    var myPropBag = this.props;
    alert(myPropBag.get_fieldValues()["allowdesigner"]); //returns the value of the key allowdesigner
function failedGettingProperty(args, sender)
     //handle errors here
