Detailed explanation of jQuery encapsulated paging component
Since the project needed to achieve the paging effect, I searched for it in the jQuery plug-in library, but I couldn’t find the effect I wanted, so I encapsulated a paging component myself. This article mainly introduces the paging component based on jQuery encapsulation in detail. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.
Idea:
Mainly based on the paging template established based on the prototype during initialization and then binding dynamic events to achieve the paging effect of refreshing the DOM.
1.page.init.css
@charset "utf=8";
*{
box-sizing: border-box;
padding: 0;

}
.page{

}
.page .page_to{
display: inline-block;

}
.page .page_to li{

height: auto;
border: 1px solid #ddd;
padding:5px 10px;

.page .page_to li.page_hide{

.page .page_to li:hover{

}
.page .page_to li:first-child{
border-left-width: 1px;
}
.page .page_jump{
display: inline-block;

}
.page .page_jump input.page_jump_input{

text-align: center;

Paging component initialization can be completed through window.pageInit= $.pageInit=pageInit.
The exposed interfaces are:
1.container: DOM container, default.page
2.setPos: HTML position placed by DOM, default body
3.totalPages: Default number of pages, required, default null
4.totalLists: Default total number of data, required, default null
5.initPage: Current page ,Default first page
6.inputVal: Jump page, default first page
7.callBack: Executed callback function, required, default null

Add the function function you need to execute through the callBack interface, and only perform dynamic DOM rendering when true is required.

The default display behavior for components in the Angular framework is not for block-level elements. This design choice promotes encapsulation of component styles and encourages developers to consciously define how each component is displayed. By explicitly setting the CSS property display, the display of Angular components can be fully controlled to achieve the desired layout and responsiveness.
