小編給大家分享一下Vue.js+bootstrap前端如何實現分頁和排序,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
效果圖:
語法:
數據綁定 {{...}}或者v-model
<td >{{dataItem.id}}</td> <input v-model="message">
事件綁定 v-on
<th v-on:click="sortBy('id')">ID</th>
循環 v-for
<option v-for="item in arrPageSize" value="{{item}}">{{item}}</option>
判斷 v-if
<span v-if="item==1" class="btn btn-default" v-on:click="showPage(1,$event)">首頁</span>
過濾器 Vue.filter
//定義 Vue.filter( 'name' , function(value) { return value * .5 ; }); //使用 <td>{{dataItem.age | name}}</td> <input v-model="message | name">
排序orderBy
<tr v-for="dataItem in arrayData | orderBy sortparam sorttype"> <td >{{dataItem.id}}</td> <td >{{dataItem.name}}</td> <td>{{dataItem.age}}</td> </tr>
html
<div id="test" class="form-group"> <div class="form-group"> <div class="page-header"> 數據 </div> <table class="table table-bordered table-responsive table-striped"> <tr> <th v-on:click="sortBy('id')">ID</th> <th>姓名</th> <th v-on:click="sortBy('age')">年齡</th> </tr> <tr v-for="dataItem in arrayData | orderBy sortparam sorttype"> <td >{{dataItem.id}}</td> <td >{{dataItem.name}}</td> <td>{{dataItem.age}}</td> </tr> </table> <div class="page-header">分頁</div> <div class="pager" id="pager"> <span class="form-inline"> <select class="form-control" v-model="pagesize" v-on:change="showPage(pageCurrent,$event,true)" number> <option v-for="item in arrPageSize" value="{{item}}">{{item}}</option> </select> </span> <template v-for="item in pageCount+1"> <span v-if="item==1" class="btn btn-default" v-on:click="showPage(1,$event)"> 首頁 </span> <span v-if="item==1" class="btn btn-default" v-on:click="showPage(pageCurrent-1,$event)"> 上一頁 </span> <span v-if="item==1" class="btn btn-default" v-on:click="showPage(item,$event)"> {{item}} </span> <span v-if="item==1&&item<showPagesStart-1" class="btn btn-default disabled"> ... </span> <span v-if="item>1&&item<=pageCount-1&&item>=showPagesStart&&item<=showPageEnd&&item<=pageCount" class="btn btn-default" v-on:click="showPage(item,$event)"> {{item}} </span> <span v-if="item==pageCount&&item>showPageEnd+1" class="btn btn-default disabled"> ... </span> <span v-if="item==pageCount&&item!=1" class="btn btn-default" v-on:click="showPage(item,$event)"> {{item}} </span> <span v-if="item==pageCount" class="btn btn-default" v-on:click="showPage(pageCurrent+1,$event)"> 下一頁 </span> <span v-if="item==pageCount" class="btn btn-default" v-on:click="showPage(pageCount,$event)"> 尾頁 </span> </template> <span class="form-inline"> <input class="pageIndex form-control" type="text" v-model="pageCurrent | onlyNumeric" v-on:keyup.enter="showPage(pageCurrent,$event,true)" /> </span> <span>{{pageCurrent}}/{{pageCount}}</span> </div> </div> </div>
javascript
//只能輸入正整數過濾器 Vue.filter('onlyNumeric', { // model -> view // 在更新 `<input>` 元素之前格式化值 read: function (val) { return val; }, // view -> model // 在寫回數據之前格式化值 write: function (val, oldVal) { var number = +val.replace(/[^\d]/g, '') return isNaN(number) ? 1 : parseFloat(number.toFixed(2)) } }) //模擬獲取數據 var getData=function(){ var result = []; for (var i = 0; i < 500; i++) { result[i] ={name:'test'+i,id:i,age:(Math.random()*100).toFixed()}; } return result; } var vue = new Vue({ el: "#test", //加載完成后執行 ready:function(){ this.arrayDataAll = getData(); this.totalCount = this.arrayDataAll.length; this.showPage(this.pageCurrent, null, true); }, data: { //總項目數 totalCount: 200, //分頁數 arrPageSize:[10,20,30,40], //當前分頁數 pageCount: 20, //當前頁面 pageCurrent: 1, //分頁大小 pagesize: 10, //顯示分頁按鈕數 showPages: 11, //開始顯示的分頁按鈕 showPagesStart: 1, //結束顯示的分頁按鈕 showPageEnd: 100, //所有數據 arrayDataAll:[], //分頁數據 arrayData: [], //排序字段 sortparam:"", //排序方式 sorttype:1, }, methods: { //分頁方法 showPage: function (pageIndex, $event, forceRefresh) { if (pageIndex > 0) { if (pageIndex > this.pageCount) { pageIndex = this.pageCount; } //判斷數據是否需要更新 var currentPageCount = Math.ceil(this.totalCount / this.pagesize); if (currentPageCount != this.pageCount) { pageIndex = 1; this.pageCount = currentPageCount; } else if (this.pageCurrent == pageIndex && currentPageCount == this.pageCount && typeof (forceRefresh) == "undefined") { console.log("not refresh"); return; } //處理分頁點中樣式 var buttons = $("#pager").find("span"); for (var i = 0; i < buttons.length; i++) { if (buttons.eq(i).html() != pageIndex) { buttons.eq(i).removeClass("active"); } else { buttons.eq(i).addClass("active"); } } //從所有數據中取分頁數據 var newPageInfo = []; for (var i = 0; i < this.pagesize; i++) { var index =i+(pageIndex-1)*this.pagesize; if(index>this.totalCount-1)break; newPageInfo[newPageInfo.length] = this.arrayDataAll[index]; } this.pageCurrent = pageIndex; this.arrayData = newPageInfo; //計算分頁按鈕數據 if (this.pageCount > this.showPages) { if (pageIndex <= (this.showPages - 1) / 2) { this.showPagesStart = 1; this.showPageEnd = this.showPages - 1; console.log("showPage1") } else if (pageIndex >= this.pageCount - (this.showPages - 3) / 2) { this.showPagesStart = this.pageCount - this.showPages + 2; this.showPageEnd = this.pageCount; console.log("showPage2") } else { console.log("showPage3") this.showPagesStart = pageIndex - (this.showPages - 3) / 2; this.showPageEnd = pageIndex + (this.showPages - 3) / 2; } } } //排序 },sortBy: function (sortparam) { this.sortparam = sortparam; this.sorttype = this.sorttype == -1 ? 1 : -1; } } });
