Jquery中的动态分页 [英] Dynamic pagination in Jquery

问题描述

我有这段代码：

//Pagination
	pageSize = 8;

	showPage = function(page) {
	    $(".line-content").hide();
	    $(".line-content").each(function(n) {
	        if (n >= pageSize * (page - 1) && n < pageSize * page)
	            $(this).show();
	    });        
	}
    
	showPage(1);

	$("#pagin li a").click(function() {
	    $("#pagin li a").removeClass("current");
	    $(this).addClass("current");
	    showPage(parseInt($(this).text())) 
	});

.current {
  color: green;
}

#pagin li {
  display: inline-block;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="line-content">1 I have some content</div>
<div class="line-content">2 I have some content</div>
<div class="line-content">3 I have some content</div>
<div class="line-content">4 I have some content</div>
<div class="line-content">5 I have some content</div>
<div class="line-content">6 I have some content</div>
<div class="line-content">7 I have some content</div>
<div class="line-content">8 I have some content</div>
<div class="line-content">9 I have some content</div>
<div class="line-content">10 I have some content</div>
<div class="line-content">11 I have some content</div>
<div class="line-content">12 I have some content</div>

<ul id="pagin">
            <li><a class="current" href="#">1</a></li>
            <li><a href="#">2</a></li>
            <li><a href="#">3</a></li>
            <li><a href="#">4</a></li>
</ul>

我不想在我的HTML文件中手动编写数字，而是希望根据要显示的div数自动生成数字。

Instead of writing numbers manually in my HTML file, I want the numbers generate automatically according to the number of divs to display.

我所使用的代码但第3页和第4页中没有任何内容。我希望它们能够使用Jquery动态更改

The code I have works but there is nothing in page 3 and 4. Instead of update the numbers in my HTML file, I want them to change dynamically with Jquery

推荐答案

计算页数而不是通过循环创建链接到页面。

calculate page count than via a loop create links to pages.

//Pagination
	pageSize = 8;

	var pageCount =  $(".line-content").length / pageSize;
    
     for(var i = 0 ; i<pageCount;i++){
        
       $("#pagin").append('<li><a href="#">'+(i+1)+'</a></li> ');
     }
        $("#pagin li").first().find("a").addClass("current")
    showPage = function(page) {
	    $(".line-content").hide();
	    $(".line-content").each(function(n) {
	        if (n >= pageSize * (page - 1) && n < pageSize * page)
	            $(this).show();
	    });        
	}
    
	showPage(1);

	$("#pagin li a").click(function() {
	    $("#pagin li a").removeClass("current");
	    $(this).addClass("current");
	    showPage(parseInt($(this).text())) 
	});

.current {
  color: green;
}

#pagin li {
  display: inline-block;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="line-content">1 I have some content</div>
<div class="line-content">2 I have some content</div>
<div class="line-content">3 I have some content</div>
<div class="line-content">4 I have some content</div>
<div class="line-content">5 I have some content</div>
<div class="line-content">6 I have some content</div>
<div class="line-content">7 I have some content</div>
<div class="line-content">8 I have some content</div>
<div class="line-content">9 I have some content</div>
<div class="line-content">10 I have some content</div>
<div class="line-content">11 I have some content</div>
<div class="line-content">12 I have some content</div>

<ul id="pagin">
         
</ul>
