HTML分頁外掛功能實現
阿新 • • 發佈：2018-12-17
分頁功能實現案例展示如下：
1.先引入css樣式和jQuery，再引入分頁外掛toPage.js，謹記順序不能亂
<link rel="stylesheet" href="css/toPage.css">
<script src="script/jquery.min.js"></script>
<link rel="stylesheet" href="css/toPage.css">
2.定義兩個分頁容器的div展示，實際應用時定義一個分頁容器即可，這裡主要是展示案例所以定義了兩個容器，如下：
<!--分頁容器_1--> 3.接著我們使用外掛寫js程式碼
<!--外掛使用-->
<script>
/*容器1引數*/
var obj_1={
obj_box:'.page_1',//翻頁容器
total_item:72//條目總數
/*per_num:10,//每頁條目數
current_page:8//當前頁*/
} 4.關於如何修改每頁展示的內容：在toPage.js裡面有一個change_content()方法，請自行修改即可
以下程式碼解讀：定義了ul，li，分頁展示：編號，分頁條目；最後要記得吧內容繫結到$(obj_box).children(’.page_content’).html下才能展示出來
function change_content() {
/*此處根據專案實際自行編寫頁面顯示內容的方法,舉例說明:*/
var page_content='<ul style="width: 300px;margin: 10px auto;">';//當前頁內容
for(var i=0;i<per_num;i++){
page_content+='<li>'+((current_page-1)*per_num+i+1)+',分頁條目</li>';
}
page_content+='</ul>';
$(obj_box).children('.page_content').html(page_content);
}
另外，也可以也可以寫ajax來展示分頁資料，如下：
function change_content() {
$.ajax({
type: 'get',
url: 'http://xxxx',
dataType: "json",
data: json_data,
error: function (data) {
//請求失敗時被呼叫的函式
err_func(data);
},
success: function (data) {
//對資料的各種操作operation(data),返回需要展示的頁面內容，
//最後繫結到$(obj_box).children('.page_content').html即可展示出來
var page_content=operation(data);
$(obj_box).children('.page_content').html(page_content);
}
});
}
我自己製作的小說網站，也使用了該分頁功能，感覺不錯，值得推薦
也歡迎訪問我的小說網站
