基于Vue2.0的分页组件

let hasPrev = page > 1;
let hasNext = page < pageCount;

//上一页
pageList.push({
class: hasPrev ? '' : 'disabled',page: hasPrev ? page - 1 : page,html: prevHtml
});

//首页
pageList.push({
class: page == 1 ? 'active' : '',page: 1,html: 1
});

var p0 = Math.floor(maxPage / 2);
var p1 = 1 + 2 + p0; //首页+省略至少2个页码+中间页面数的一半

var start,end;
if (page >= p1) {
start = page - p0;
//前置省略号
pageList.push({
class: 'dot',page: page,html: '...'
});
} else {
start = 2;
}

var p2 = page + p0;
if (p2 < pageCount) {
end = p2;
} else {
end = pageCount - 1;
}

//页码列表
for (let i = start; i <= end; i++) {
pageList.push({
class: page == i ? 'active' : '',page: i,html: i
});
}

if (end < pageCount - 1) {
//后置省略号
pageList.push({
class: 'dot',html: '...'
});
}

//尾页
if (pageCount > 1) {
pageList.push({
class: page == pageCount ? 'active' : '',page: pageCount,html: pageCount
});
}

//下一页
pageList.push({
class: hasNext ? '' : 'disabled',page: hasNext ? page + 1 : page,html: nextHtml
});

return pageList;
}
},methods: {
setPage: function (item) {
if (item.class == '') {
this.$emit('pagehandler',item.page);
}
}
}
});
