In general, for this situation, our conventional approach is to first unbind, then bind, as follows:$ (selector). Unbind (' click '). Bind (' click ', function () {...});When this has a problem, unbind will unbind all of its previous click events and may affect other bindings, as there are two ways to resolve them:The first type:Use the event command space to uniquely identify the binding of this click, so that the event that the other click binds is

The hibernate Jndi name bindings are implemented in the Net.sf.hibernate.impl.SessionFactoryObjectFactory program, and I'll analyze the process of hibernate binding Jndi: The way we get sessionfactory is generally to write code like this: Configuration conf = new Configuration().addClass(Cat.class); SessionFactory sf = conf.buildSessionFactory(); First, the new Configuration () creates a Configuration that reads the configuration file (hibernate.pr

function, first registration of the first execution, after the registration after execution. (vi) Blocking event bubbling and capturing By default, multiple event-handling functions are executed in the order in which they are in the DOM event flow model. If an event occurs on a child element and does not need to perform an event handler that is registered on the parent element, then we can stop capturing and bubbling to avoid meaningless function calls. The 5 types of event

Android Studio has a terminal in the toolbar below that can use the cmd command, we can bind git inside, so we don't have to go out every time we commit the code.The steps are as follows:1.file--settings--versoon control--git--test to test that your git installation is correct.2. Click Start-All Programs-Find Git folder-right-click Git bash Properties--Copy the target's string address.3. Go back to the column of Studio--file--settings--terminal--shell path and copy the address in--okThis way you

Problem: Many times it is found that binding the Click event to a dynamically generated element is not valid ~Cause: Binding directly to dynamically generated elements is not valid because jquery scans the document to find all the $ (') elements and binds the function to the click event of each element, indicating that there are elements that exist on the existing page and that the dynamically generated elements are not included .Workaround: The agent or delegate on (), the implementation princi

, which can bring a performance benefit. Like what:For example, if the Click event is bound to a Document object, the click event of any element on the page bubbles to the Document object for processing.Notice the Second optional parameter in the description of.

For example, add the second parameter, the selector button:Results:When the event bubbles to the Document object, the target of the detection event, if matched with the incoming selector (this is the button), triggers th

HighChat dynamically binds data records and highchat bindings Recently, I started to perform graphic operations and struggled for a long morning. I had no idea how to bind the highchat dynamic data. I tried multiple times and found that 1. The data on the X axis is in an array format. When I transfer the data from the background to the foreground, js uses arrays to process the data. If I assign values to chat, no error will be reported, 2. The data on
