Angular JS - 如何将Javascript对象导出到XLS文件？

Question

实际上,我在我的控制器中有一个对象,我只想将该对象导出为.xls或.csv file.i使用了很多这样的方法:

HTML

<script src="https://rawgithub.com/eligrey/FileSaver.js/master/FileSaver.js" type="text/javascript" />
<div ng-controller="myCtrl">
    <button ng-click="exportData()">Export</button>
    <br />
    <div id="exportable">
    <table width="100%">
        <thead>
            <tr>
                <th>Name</th>
                <th>Email</th>
                <th>DoB</th>
            </tr>
        </thead>
        <tbody>
            <tr ng-repeat="item in items">
                <td>{{item.name}}</td>
                <td>{{item.email}}</td>
                <td>{{item.dob | date:'MM/dd/yy'}}</td>
            </tr>
        </tbody>
    </table>
    </div>
</div>

使用Javascript

function myCtrl($scope) {
    $scope.exportData = function () {
        var blob = new Blob([document.getElementById('exportable').innerHTML], {
            type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8"
        });
        saveAs(blob, "Report.xls");
    };

    $scope.items = [{
        name: "John Smith",
        email: "j.smith@example.com",
        dob: "1985-10-10"
    }, {
        name: "Jane Smith",
        email: "jane.smith@example.com",
        dob: "1988-12-22"
    }, {
        name: "Jan Smith",
        email: "jan.smith@example.com",
        dob: "2010-01-02"
    }, {
        name: "Jake Smith",
        email: "jake.smith@exmaple.com",
        dob: "2009-03-21"
    }, {
        name: "Josh Smith",
        email: "josh@example.com",
        dob: "2011-12-12"
    }, {
        name: "Jessie Smith",
        email: "jess@example.com",
        dob: "2004-10-12"
    }]
}

但这不适用于分页table.is有没有办法直接导出对象(在这个例子中$ scope.item)到文件(xls,csv)？

Answer 1

是的,您可以使用带有XLSX.js库的Alasql JavaScript库来保存数据.这是一个例子:

首先:在页面中包含两个JavaScript库:

• alasql.min.js
• xlsx.core.min.js

第二步:用你的代码替换exportData()函数:

  $scope.exportData = function () {
      alasql('SELECT * INTO XLSX("john.xlsx",{headers:true}) FROM ?',[$scope.items]);
  };

第三:对于CSV文件 - 只需使用CSV()函数:

  alasql('SELECT * INTO CSV("john.csv",{headers:true, separator:";"}) FROM ?',[$scope.items]);

您可以在jsFiddle中使用此示例.
