vue.js分页+加载前后效果处理经典例子

站长苏飞

关于分页，这个里我们直接重置一下v-for的indexs，就是循环的结束值。因为v-for没有很好的办法设置步长以及怎么设置初始值

看代码

 computed: {
indexs: function () {
//开始页
var left = 1;
//结束页
var right = this.pageCount;
//在显示的页码数组
var ar = [];
if (this.pageCount >= 10) {
if (this.pageIndex > 6 && this.pageIndex < this.pageCount - 4) {
left = this.pageIndex - 5
right = this.pageIndex + 4
} else {
if (this.pageIndex <= 6) {
left = 1
right = 10
} else {
right = this.pageCount
left = this.pageCount - 8
}
}
}
while (left <= right) {
ar.push(left)
left++
}
return ar
}
}

直接复制到你的vue对象中，然后配置一下
pageCount总页数
pageIndex当前页就行了。

控制数据是否显示，这里直接用一个隐藏的行来处理
html部分

 <tr id="msg" style="display:none;" ></tr>

默认不显示
js控制如下，加载中，，，

[JavaScript] 纯文本查看 复制代码

 $("#msg").html(" <td align='center' colspan='4'>数据加载中...</td>");
$("#msg").show();

没有数据时

[JavaScript] 纯文本查看 复制代码

 rw.userlogs ="";
$("#msg").html("<td align='center' colspan='4'>未查询到数据...</td>");

出错时

[JavaScript] 纯文本查看 复制代码

 $("#msg").html("<td align='center' colspan='4'>出现异常，请联系管理员！！！</td>");

全部JS部分

 <script type="text/javascript">
var rw = new Vue({
el: "#grid",
data: {
pageIndex: 1, //当前页 
pageCount: 0, //总页数
totalcount: 0, //总行数
username: "", //
userlogs: ""//用户列表集合
},
methods: {
getdata: function (n) {

rw.pageCount = 0;
rw.totalcount = 0;
rw.pageIndex = 0;
rw.userlogs = "";
$("#msg").html(" <td align='center' colspan='4'>数据加载中...</td>");
$("#msg").show();

axios({
method: 'get',
url: "/System/Crm_User_logs.aspx?action=getpagelist&username=" + this.username + "&pageIndex=" + n
}).then(function (res) {
var data = res.data;
if (data.reCode > 0) {
$("#msg").hide();
rw.pageCount = Math.ceil(data.TotalCount / data.pageSize);
rw.totalcount = data.TotalCount;
rw.username = data.username;
rw.pageIndex = data.pageIndex;
rw.userlogs = data.info;
} else {
$("#msg").html("<td align='center' colspan='4'>未查询到数据...</td>");
}
}).catch(function(err){
$("#msg").html("<td align='center' colspan='4'>出现异常，请联系管理员！！！</td>");
});
}
},
computed: {
indexs: function () {
//开始页
var left = 1;
//结束页
var right = this.pageCount;
//在显示的页码数组
var ar = [];
if (this.pageCount >= 10) {
if (this.pageIndex > 6 && this.pageIndex < this.pageCount - 4) {
left = this.pageIndex - 5
right = this.pageIndex + 4
} else {
if (this.pageIndex <= 6) {
left = 1
right = 10
} else {
right = this.pageCount
left = this.pageCount - 8
}
}
}
while (left <= right) {
ar.push(left)
left++
}
return ar
}

数据行只需要把vue绑定的数据列重置为“”自动就不显示标签了，不需要再处理sho或者hide方法
