use the index of the string to participate in some operations ("2" + 1 = "21"), the result of the operation may be inconsistent with the expected.Not only will the elements of the array itself be traversed, but the additional (expando) elements added by the user will also be traversed, such as an array having such a property myarray.name, then a index= "name" will appear in a loop. Furthermore, even properties on the chain of an array prototype may b

Explorer, or Jav Ascript engine and Firefox's XPCOM infrastructure). Here are some rules of thumb to avoid memory leaks: Use an event system to attach an event handler function The most common circular reference mode [DOM element--> event handler--> closure Scope--> DOM] is discussed in this MSDN blog article. To avoid this problem, you can use a rigorously tested event system to attach event-handling functions such as Google doctype, Dojo, or JQuery. In addition, the use of inline (inline)

object's properties. Second, the overall structure: Data cache Jquery.extend ({ //Global Cached Object Cache : {},// unique ID seed uuid:0, //Unique identification of each jQuery copy in the page expando: "JQuery" + (JQuery.fn.jquery + math.random ()). Replace (/\d/g, ""), //whether there is an associated data hasdata:function ( {}, //set, read custom data or internal data data:function (elem, name, data, pvt) {

attach event-handling functions such as Google doctype, Dojo, or JQuery. In addition, the use of inline (inline) event-handling functions in IE can result in another type of leakage. This is not a common circular reference leak, but a leak of a temporary anonymous script object in memory. For more information, see the "DOM Insertion Order leak model" for understanding and resolving IE leak mode (understanding and solving Internet Explorer leak Patterns) (DOM insertion orders leak M Odel) "sect

instance:privatememberclass=new privatememberclass (); Trace (Instance.privateprop); A compilation error occurs at this time. This is a common mistake many people always ask why private properties can be accessed by instances, and now you know. Dynamic classes allow for the dynamic extension of a class (for example, by allowing new properties or methods to be added). This is called expando in a JScript.NET program, and if a class is not a dynamic cla

That temp1 has a get method that can directly obtain its cache object. Assume that you want to view the id of the object bound to the event is clickMe. Then executetemp1.get($('#clickMe').get(0))(Ortemp1.get(document.querySelector('#clickMe'))) It will display something equivalent to jquery1.x above. The method is the same as

Therefore, please pass the query result to this function for calling. B. JQuery Processing 　　In jQuery ajax, jsonp and jsonpCallback specify the "callback" and "remoteLoad" values respectively. The default value of jsonp is "callback", and the default value of jsonpCallback is a timestamp field (jQuery. expando +
