关于若依前端分页首次使用BootstrapPager 即bootstrap扩展插件

本文分页采用插件托管地址：

强调，本插件是从bootstrap3 基础之上开始的，我采用bootstrap4,所以要选择

https://gitee.com/xuzhanga/BootstrapPager/blob/master/test/demo2.html

1：下载后引入分页插件,(如在<head>头部

1	`<script src="../../ibaiqi.js/bootstrapPager.js"></script>`

2:后端，采用是若依封装返回JSON的方法如下

 /**
     * 查询文章列表
     * @param article
     * @return
     */
    @GetMapping("/list")
    @ApiOperation(value = "article文章列表")
    public TableDataInfo list(BlogsArticle article){
        startPage();
        List<BlogsArticle> blogsArticles = iBlogsArticleService.selectBlogsArticleList(article);
        return getDataTable(blogsArticles);
    }

3:用postMan请求，带上第一页，每页显示3条数据，看返回接口数据是否正确如下

4:先用jquery的.get()测试是否和postMan返回一致

<script type="text/javascript">
    let currentPage = 1;  //当前页码，即第几页
    let pageSize = 5;   //每页显示多少条
    //返回文章列表
    function articleList() {
        $.get(
            baseHref += "/api/v1/blogs/article/list", { //分页参数传递，即可分页           
                pageNum: currentPage,
                pageSize: pageSize,
            },
            function(articles) {
                var articleResV = "<ul>" //拼接返回文章列表
                $.each(articles.rows, function(i, article) {
                    // console.log("article.articleTitle: ",article.articleTitle);
                    articleResV += "<li><a href='../../views/blogs/article.html' title=" + article.articleTitle + ">" +
                        subStrLength(
                            article.articleTitle, 60) + "</a>"
                    articleResV += "<div><span>热点</span>:" + subStrLength(article.createBy, 50) + "</div></li>"
                })
                articleResV += "</ul>"
                //把文章返回，挂载到节点上
                $("#articleList").append(articleResV) 
                 
            },
            "json"
        )
    }
     
</script>

4：若依接供接口 bootstrap4 下此分页
