example ms-text= "AAA", we get its view refresh function from the property name (all the view refresh functions are defined on the Avalon.bindingexecutors object), the evaluation function is compiled by the internal parseexpr method.In general, is the upper layer dependent on the lower layer, the underlying changes, will automatically bubble up, to the view Refresh function level, to realize the change of view, there is only one exception, that is Ms-duplex. It will secretly bind some events to

ArticleDirectory The main advantages are as follows: Aveon has been extracted from the mass framework without any dependencies. The main advantages are as follows: Simple to use, add bindings in HTML, define viewmodel with avron. Define in JS, and then call the avron. scan method, it will work! Compatible with IE6 No dependency, only 77 K, 22 K after compression Supports MPs queue style filtering functions to facilitate

Ms-if is one of the process bindings that, if the expression is true, prints the current element out of the page, rather than moving it out of the DOM tree. Its effect looks similar to the ms-visible effect in the previous section, but it affects: empty pseudo-class, and can be more economical performance. MS-IF also has a branch, called Ms-if-loop, which is used in conjunction with the ms-repeat binding, so say it later.We can compare the two with the following example:Mini

Avalon's ViewModel object inherits three methods from its internal eventmanager , $watch, $unwatch, $fire three methods that are the subject of our section.Words, like their name, are very straightforward and know what to do at a glance. Let's start with the $watch method, which listens to the monitoring and calculation Properties of the first layer of the current VM, and if an attribute is an object that wants to monitor its descendants ' properties, it needs to navigate to the object using the

-click-1=fn2, MS-CLICK-2=FN3), to support the transfer of a parameter (the default first parameter is the event object, and if the first position is accounted for, we can use the $event to reference the event object elsewhere.) ） Avalon has been repaired with Ms-mouseenter, Ms-mouseleave, and can be learned here with these two events. To Chrome30, all browsers natively support both events.Finally, the MouseWheel event was modified, the main problem is the emergence of Firefox, it is not willi

Many of the functions of jquery can be handled through the binding properties of Avalon, such as the click Method corresponding to the Ms-click,css method corresponding to the Ms-css,toggle method corresponding to the ms-visible, its data caching function Avalon also moved over. But unlike jquery, Avalon is the data-☆ attribute that saves data directly to the element node's HTML5. When you restore data from the Data-☆ property, it will simply convert the data back to you.In Ms-data bindings, con

update, but cannot notify him of other attributes in viewmodel. For monitoring attributes, we may use this method to implement inter-sibling communication. $ Watch (prop, callback ?), Stop notification The framework does not convert an attribute starting with $ to a monitoring attribute. Attribute names placed in $ skiparray are not converted to monitoring attributes. An object containing get and set is considered as a computing attribute

!Let's take a little more practical example.In addition, we can also use data-each-rendered to specify that these elements are inserted after the DOM is rendered and executed after the callback, this pointer to the element node, there is a parameter represented as the current operation, is add, Del, move, Index or clear.We've said something about the array, and we'll see how it operates the hash. For hashing, ms-repeat only produces $key, $val, $outer three variables, no $index or anything. $key

VML elements must be assigned using the Bracket method The SVG element must be assigned a value of setattribute if (ISVML (Elem)) {Isinnate = True } else if (window. Svgelement !

Implementation and description of the wpf mvvm enterprise framework starting from 0, wpfmvvm When talking about desktop applications, our first response is how the messaging mechanism is handled. Let's talk about this windows messaging mechanism first. When talking about the word "Message mechanism", we will all think of Windows Message mechanism.

" Xmlns:d= "http://schemas.microsoft.com/expression/blend/2008" mc:ignorable= "D" > Now we can go to the MainWindow to add the template, the structure is as follows　As you can see, there are different template correspondence for the ViewModel, and then you ask, how can something like this not a control show up in the interface? This is going to define the Uilayout.config file.You'll notice a layoutanchorable, and you'll notice there's a contentid called Codetree, and that

Later in our project will be a large number of templates, mainly refers to the space template, the data template will be used relatively little, below I want to introduce the control template and data template, I see a great god written relatively good, I tidied up, so that we can better understand, for everyone to reference,First introduce DataTemplateDataTemplate: Is the performance of the data content, a piece of data shows what it looks like1. The data template is commonly used in the follow

The current version is updated as follows. Add a $ JSON object, which corresponds to a pure JS object in viewmodel. There are no special methods and attributes added by accessors and frameworks, so that users can directly submit it to the background. This object will be synchronized every time we modify the viewmodel attribute. Now we can synchronize the view and model simultaneously when modifying the viewmodel. Refactor avron. Define, collection, evaluate function,CodeMore streamlined, 5

After 2 small versions of the test water, avalon1.5 This new architecture has finally matured.First, the configuration of the component, the name changed a lot, so that everyone is satisfied.Ms-duplex, Ms-include, ms-if and other instructions for bug fixes.Some ONIUI components have also been successfully converted into new component forms, summarizing some routines.Of course, in the end I imagined that react would be able to implement double buffering without using settimeout. This will increas

. The memory on the phone is more serious, you can adjust this threshold point less.Avalon.config ({lmaxrepeatsize:40})Dettachvmodels is the decision to add a $vmodels, $vmodel property on the This object bound by the event. Previously added by default, now is not added by default, this is due to CG recycling considerations. And under Ie6-8, adding the $vmodels property for an element does not know why it throws an exception. See Source:$vmodels, $vmodel should be little known, let's not care ab
