String.format for javascript (C# .NET like syntax for concatenating strings)

Here is a little hack to make javascript behave more like .NET with string.format…

usage:

var selector = String.format("#container{0} div.lineItem{1}[data-entryid='{2}']", containerId, itemId, entryId);

js code:

//String.format for js.
if (!String.format) {
String.format = function (format) {
var args = Array.prototype.slice.call(arguments, 1);
return format.replace(/{(\d+)}/g, function (match, number) {
return typeof args[number] != 'undefined'
? args[number]
: match
;
});
};
}

Setting EPiServer 6r2 PageTypeBuilder Default Property Values

This is how you set default values for PTB 2.0 poperties in Episerver 6r2:
In the [PageTypeProperty] method attribute, add:

DefaultValue = 0, 
DefaultValueType=EPiServer.DataAbstraction.DefaultValueType.Value,

E.g.:

[PageTypeProperty(SortOrder = 100,
Tab = typeof(RelatedContentTab),
EditCaption = "Related content sort index",
Type = typeof(PropertyNumber),
DefaultValue = 20,
DefaultValueType = DefaultValueType.Value)]
int RelatedContentSortIndex { get; set; }

The DefaultValue could be any type of object. The EPiServer.DataAbstraction.DefaultValueType.Value is just an enum that indicates that a default value should be used.

However this has to be done before the page is created for the first time, else it wont have any effect until next time a page is created.

See: http://pagetypebuilder.codeplex.com/workitem/7831
Another approach, if suitable, could be to just add the “Required” in the first place to avoid missing values from the editors.

E.g.:

[PageTypeProperty(SortOrder = 100,
Tab = typeof(RelatedContentTab),
EditCaption = "Related content sort index",
Type = typeof(PropertyNumber),
Required = true)]
int RelatedContentSortIndex { get; set; }

 In EPiServer 7 this approach can be used:

jquery – Fade in each element – one after another – Stack Overflow

Let’s say you have an array of span elements:

$("span").each(function(index) {
$(this).delay(400*index).fadeIn(300);
});

(quick note: I think you need jQuery 1.4 or higher to use the .delay method)

This would basically wait a set amount of time and fade each element in. This works because you’re multiplying the time to wait by the index of the element. The delays would look something like this when iterating through the array:

Delay 400*0 (no delay, just fadeIn, which is what we want for the very first element)

Delay 400*1

Delay 400*2

Delay 400*3

This makes a nice “one after the other” fadeIn effect. It could also be used with slideDown. Hope this helps!
