前端技术(4) : 分页,java后台专用分页

使用方法 : 在两个input标签内的value赋值即可完成分页初始化,每点击以下就会跳转当前url+page=跳转的页数;

效果图:

注: 需引入jQuery

代码如下:

html:

页面添加js:

	// 初始化
	// 当前页
	var current_page = $("input[name='current_page']").val();
	// 总页数
	var total_page = $("input[name='total_page']").val();
	 
	var a = parseInt(current_page);
	var b = parseInt(total_page);
	var back = 'back';
	var next = 'next';
	var end = 'end';
	//分页
	$("#page").paging({
		pageNo: a,
		totalPage: b,
		// totalSize: 300,
		callback: function(num) {
			// alert(num)
		}
	})
	// 只有一页时隐藏分页
	console.log(total_page)
	if(total_page == '1' || total_page == '0'){
		$("#page").hide();
	}

css:

* {
	padding: 0;
	margin: 0;
}

.page_div {
	margin-top: 20px;
	margin-bottom: 20px;
	font-size: 15px;
	font-family: "microsoft yahei";
	color: #666666;
	margin-right: 10px;
	padding-left: 20px;
	box-sizing: border-box;
}

.page_div a {
	min-width: 30px;
	height: 28px;
	border: 1px solid #dce0e0!important;
	text-align: center;
	margin: 0 4px;
	cursor: pointer;
	line-height: 28px;
	color: #666666;
	font-size: 13px;
	display: inline-block;
}

#firstPage,
#lastPage {
	width: 50px;
	color: #0073A9;
	border: 1px solid #0073A9!important;
}

#prePage,
#nextPage {
	width: 70px;
	color: #0073A9;
	border: 1px solid #0073A9!important;
}

.page_div .current {
	background-color: #0073A9;
	border-color: #0073A9;
	color: #FFFFFF;
}

.totalPages {
	margin: 0 10px;
}

.totalPages span,
.totalSize span {
	color: #0073A9;
	margin: 0 5px;
}

.go_page {
	min-width: 30px;
	height: 28px;
	border: 1px solid #dce0e0!important;
	width: 30px;
}

#go_cl {
	color: #0073A9;
	border: 1px solid #0073A9!important;
}
