principles: Figure 1: Basic cyclic Reference Model The leakage caused by this model is based on the reference count of COM. The script engine object maintains reference to the DOM object and waits for all references to be removed before the DOM object pointer is cleared and released. In our example, our script engine object has two references: The Script Engine scope and the expando attribute of the DOM object. When the script engine is terminated, t

For the most classic explanation of ID Name, "ID is like our ID card, and Name is like our Name". That is to say, ID is unique in an html document, but the Name can be repeated, just as our personal names can be repeated, but the ID card is indeed unique across China (PS: It is said that there are repeated ^_^) However, for the document. getElementsByName and document. getElementById methods, IE does not strictly distinguish between ID and Name. For example: Two methods are described in MSDN:

1. bind method. The last fn parameter is redundant. Copy codeThe Code is as follows: // Handle object literals If (typeof type = "object "){ For (var key in type ){ This [name] (key, data, type [key], fn ); } Return this; } 2.

In recent years, the C # language has been a long way, the code style is more concise and beautiful, such as common generics and its constraints, nullable types, implicit types, anonymous types and delegates, the following table can be used in this part of the relatively simple characteristics of the use of a preliminary understanding. Characteristics Example Generics and their constraints Class sample Nullable types Nullabl

OverviewStores or reads data on an element, returning a jquery object.When the parameter has only one key, the value corresponding to the key stored in the DOM is read by the jquery object, and it is worth noting that if the browser supports HTML5, it can also read the values stored in the DOM using data-[key] = [value]. See the last example.When the parameter is two, the data for the Key-value key-value pair is stored in the DOM corresponding to the jquery object.If the jquery collection points

been completed yet. Because these result sets do not necessarily meet our requirements, we need to filter them. Operations on arrays are required. This involves the features of the class array of jquery objects. We can put together the functions related to these arrays for analysis. When the final set of requirements is formed, we need to complete what we really want to do and operate the DOM elements in the set.How? What are the operations? Is it true that the attribute, class, style, CSS, an

process of turning the abstract CSS selection syntax into a specific matching function is also a compilation.1) MatcherfromtokensThe 5080-row compile function obtains a match for the token collection by referencing the 4931-row matcherfromtokens function, as follows: 1 i = group.length; // from right to left 2 while (i-- 3 cached = Matcherfromtokens (Group[i]); 4 if ( Cached[expando] { 5 Setmatchers.push ( cached); 6 } else 7

. Of course, whether it will take effect is not mentioned 2: transfer is a reference type. unreliable memory recovery may have exceeded 3: data exposure, which is easy to be directly rewritten. How can we solve these problems? JQuery introduces the concept of a data object, no matter how it is implemented internally. First, the attribute image of the node has a gray custom key and value gray, which means that it cannot be enumerated through, in ES5, Apis directly support code copying. // If not,

Many students in the project like to store data on the HtmlElement property, such as 1234 "some data">Test Added the custom attribute "data" and the value "some data" to the div in the page.

Before the jQuery1.8.0 version, we wanted to get an event handler for a DOM binding to do this: $.data (domobj, ' events '); // or $ (' selector '). Data (' Events ')jquery1.8. Beginning with version 0, jquery suddenly does not support this use, but instead to a function called ' _data ', that is, 1.8.0 and later versions you can use:$._data (domobj, ' events ');//Note that this does not work like $ (' selector '). _data (' Events '). /*For example, you can write*/$._data ($ (' #box '

In terms of the overall structure, lazytreegrid is not much different from treegrid and DataGrid. A view is a directly visible part of a grid, including the grid header, row, column, cell, and treegrid-specific node expansion buttons, the entire treegrid obtains data and constructs content through the rolling event of the virtual scroll bar in the content vi
