基本使用

需要先创建一个div的容器,来显示表格

<div id="spreadsheet"></div>
复制代码

需要在 script中初始化表格,这样表格就会显示出来了

var data = [
    ['Jazz', 'Honda', '2019-02-12', '', true, '$ 2.000,00', '#777700'],
    ['Civic', 'Honda', '2018-07-11', '', true, '$ 4.000,01', '#007777'],
];

jexcel(document.getElementById('spreadsheet'), {
    data:data,
    columns: [
        { type: 'text', title:'Car', width:120 },
        { type: 'dropdown', title:'Make', width:200, source:[ "Alfa Romeo", "Audi", "Bmw" ] },
        { type: 'calendar', title:'Available', width:200 },
        { type: 'image', title:'Photo', width:120 },
        { type: 'checkbox', title:'Stock', width:80 },
        { type: 'numeric', title:'Price', width:100, mask:'$ #.##,00', decimal:',' },
        { type: 'color', width:100, render:'square', }
     ]
});
复制代码

React中使用

class Jexcel extends React.Component {
    constructor(props) {
        super(props);
        this.options = props.options;
        this.wrapper = React.createRef();
    }

    componentDidMount = function() {
        this.el = jexcel(this.wrapper.current, this.options);
    }

    addRow = function() {
        this.el.insertRow();
    }

    render() {
        return (
            <div>
                <div></div><br/><br/>
                <input type='button' value='Add new row' onClick={() => this.addRow()}></input>
            </div>
        );
    }
}

var options = {
    data:[[]],
    minDimensions:[10,10],
};

ReactDOM.render(<Jexcel options={options} />, document.getElementById('spreadsheet'))
复制代码

Vue中使用

import jexcel from 'jexcel'
import 'jexcel/dist/jexcel.css'
var data = [
  ['Jazz', 'Honda', '2019-02-12', '', true, '$ 2.000,00', '#777700'],
  ['Civic', 'Honda', '2018-07-11', '', true, '$ 4.000,01', '#007777']
]
var options = {
  data: data,
  allowToolbar:true,
  columns: [
    { type: 'text', title: 'Car', width: '120px' },
    { type: 'dropdown', title: 'Make', width: '250px', source: [ 'Alfa Romeo', 'Audi', 'Bmw' ] },
    { type: 'calendar', title: 'Available', width: '250px' },
    { type: 'image', title: 'Photo', width: '120px' },
    { type: 'checkbox', title: 'Stock', width: '80px' },
    { type: 'numeric', title: 'Price', width: '100px', mask: '$ #.##,00', decimal: ',' },
    { type: 'color', width: '100px', render: 'square' }
  ]
}
export default {
  name: 'App',
  mounted: function () {
    let spreadsheet = jexcel(this.$el, options)
    Object.assign(this, { spreadsheet })
  }
}
复制代码

加载数据

加载 javascript数组

<div id='my-spreadsheet'></div>

<script>
data = [
    ['Mazda', 2001, 2000],
    ['Pegeout', 2010, 5000],
    ['Honda Fit', 2009, 3000],
    ['Honda CRV', 2010, 6000],
];

jexcel(document.getElementById('my-spreadsheet'), {
    data:data,
    columns:[
        { title:'Model', width:300 },
        { title:'Price', width:80 },
        { title:'Model', width:100 }
    ]
});
</script>
复制代码

加载 JSON文件

<div id='my-spreadsheet'></div>

<script>
jexcel(document.getElementById('my-spreadsheet'), {
    url:'data.json',
    columns:[
        { title:'Model', width:300 },
        { title:'Price', width:80 },
        { title:'Model', width:100 }
    ]
});
</script>
复制代码

加载 CSV文件

<div id='my-spreadsheet'></div>

<script>
jexcel(document.getElementById('my-spreadsheet'), {
    csv:'demo.csv',
    csvHeaders:true,
    columns:[
        { width:300 },
        { width:80 },
        { width:100 }
    ]
});
</script>
复制代码

销毁表

<script>
var table = jexcel(document.getElementById('my-spreadsheet'), {
    csv:'demo.csv',
    csvHeaders:true,
    columns:[
        { width:300 },
        { width:80 },
        { width:100 }
    ]
});

// If second argument is true will destroy all handlers and you can't create any other instance.
jexcel.destroy(document.getElementById('my-spreadsheet'), true);
</script>
