3. Dynamic binding event plug-in: livequery

(1) Introduction to livequery plug-in

jQuery’s event binding function makes jQuery code and HTML The code can be completely separated, so that the hierarchical relationship of the code is clearer and easier to maintain. However, for HTML elements that are dynamically loaded into the page, events need to be re-binded to these elements every time, which is very inconvenient. A new plug-in was born from this, namely livequery, which can be used to register the time for the corresponding DOM element or trigger the callback function. Not only will the element matched by the current selector be bound to the event, but also elements added later via JavaScript will be bound to the event. When the element no longer matches the selector, livequery will automatically cancel the event registration, so that developers no longer need to pay attention to the source of the HTML element, only how to write its bound events.

Select a DOM element through the jQuery selector, and the livequery plug-in will persist it in the entire DOM range in real time. This means that whether the element previously existed or was dynamically loaded later, the event will be bound, just like CSS styling the element. At the same time, this plug-in achieves these functions without taking up almost any resources.

##4. jQuery UI Plug-in

jQuery UI is derived from a jQuery plug-in - Interface. The earliest version of the Interface plug-in was 1.2, which only supported the jQuery 1.1.2 version.

jQuery UI is mainly divided into 3 parts, interaction, widgets and effect library

• interaction. Here are some content related to mouse interaction. Including dragging, placing, zooming, selecting and sorting etc. Some of the widgets are made based on these interactive components. This library requires a jQuery UI core library - ui.core.js supports

• widgets. Here are mainly some interface extensions. It includes accordion navigation, autocomplete, color picker, dialog box, slider, label, calendar, magnifying glass, progress bar and spinner controller. This library requires a jQuery UI core library - ui.core.js support

• Effect library. This library is used to provide rich animation effects, so that animation is no longer limited to the animate() method. The effects library has its own set of core, effects.core.js, and does not require the support of jQuery’s core library ui.core.js
