getPosition function

getRelativeTop function

id function

Returns a collection with zero or one elements matching the specified id.

insertAdjacentHTML function

Calls insertAdjacentHTML on the specified element.

insertAdjacentHTMLUnsafe function

Calls insertAdjacentHTML on the specified element in the context of MSApp.execUnsafeLocalFunction.

markDisposable function

Attaches the default dispose API wrapping the dispose implementation to the specified element.

markSupportedForProcessing function

Marks a function as being compatible with declarative processing. Declarative processing is performed by WinJS.UI.processAll or WinJS.Binding.processAll.

query function

Returns a QueryCollection with zero or one elements matching the specified selector query.

ready function

Ensures that the specified function executes only after the DOMContentLoaded event has fired for the current page. The DOMContentLoaded event occurs after the page has been parsed but before all the resources are loaded.

removeClass function

Removes the specified class from the specified element.

requireSupportedForProcessing method

Asserts that the value is compatible with declarative processing. Declarative processing is performed by WinJS.UI.processAll or WinJS.Binding.processAll. If the value is not compatible, and strictProcessing is on, an exception is thrown.

All functions that have been declared using WinJS.Class.define, WinJS.Class.derive, WinJS.UI.Pages.define, or WinJS.Binding.converter are automatically marked as supported for declarative processing. Any other function that you use from a declarative context (that is, a context in which an HTML element has a data-win-control or data-win-options attribute) must be marked manually by calling this function. When you mark a function as supported for declarative processing, you are guaranteeing that the code in the function is secure from injection of third-party content.

setInnerHTML function

Sets the innerHTML property of the specified element to the specified text.

setInnerHTMLUnsafe function

Sets the innerHTML property of the specified element to the specified text.

setOuterHTML function

Sets the outerHTML property of the specified element to the specified text.

setOuterHTMLUnsafe function

Sets the outerHTML property of the specified element to the specified text in the context of MSApp.execUnsafeLocalFunction.

startLog function

Configures a logger that writes messages containing the specified tags to the JavaScript console.

stopLog function

Removes the WinJS logger that had previously been set up.

toggleClass function

Toggles (adds or removes) the specified class on the specified element. If the class is present, it is removed; if it is absent, it is added.
