创建html2csv.js文件并将以下代码放入其中。

Create a html2csv.js file and put the following code in it.

jQuery.fn.table2CSV = function(options) {
    var options = jQuery.extend({
        separator: ',',
        header: [],
        delivery: 'popup' // popup, value
    },
    options);

    var csvData = [];
    var headerArr = [];
    var el = this;

    //header
    var numCols = options.header.length;
    var tmpRow = []; // construct header avalible array

    if (numCols > 0) {
        for (var i = 0; i < numCols; i++) {
            tmpRow[tmpRow.length] = formatData(options.header[i]);
        }
    } else {
        $(el).filter(':visible').find('th').each(function() {
            if ($(this).css('display') != 'none') tmpRow[tmpRow.length] = formatData($(this).html());
        });
    }

    row2CSV(tmpRow);

    // actual data
    $(el).find('tr').each(function() {
        var tmpRow = [];
        $(this).filter(':visible').find('td').each(function() {
            if ($(this).css('display') != 'none') tmpRow[tmpRow.length] = formatData($(this).html());
        });
        row2CSV(tmpRow);
    });
    if (options.delivery == 'popup') {
        var mydata = csvData.join('\n');
        return popup(mydata);
    } else {
        var mydata = csvData.join('\n');
        return mydata;
    }

    function row2CSV(tmpRow) {
        var tmp = tmpRow.join('') // to remove any blank rows
        // alert(tmp);
        if (tmpRow.length > 0 && tmp != '') {
            var mystr = tmpRow.join(options.separator);
            csvData[csvData.length] = mystr;
        }
    }
    function formatData(input) {
        // replace " with "
        var regexp = new RegExp(/["]/g);
        var output = input.replace(regexp, """);
        //HTML
        var regexp = new RegExp(/\<[^\<]+\>/g);
        var output = output.replace(regexp, "");
        if (output == "") return '';
        return '"' + output + '"';
    }
    function popup(data) {
        var generator = window.open('', 'csv', 'height=400,width=600');
        generator.document.write('<html><head><title>CSV</title>');
        generator.document.write('</head><body >');
        generator.document.write('<textArea cols=70 rows=15 wrap="off" >');
        generator.document.write(data);
        generator.document.write('</textArea>');
        generator.document.write('</body></html>');
        generator.document.close();
        return true;
    }
};

将js文件包含到html页面中,如下所示:

include the js files into the html page like this:

<script type="text/javascript" src="jquery-1.3.2.js" ></script>

<script type="text/javascript" src="html2CSV.js" ></script>

TABLE:

<table id="example1" border="1"  style="background-color:#FFFFCC" width="0%" cellpadding="3" cellspacing="3">

    <tr>

        <th>Title</th>

        <th>Name</th>

        <th>Phone</th>

    </tr>

    <tr>

        <td>Mr.</td>

        <td>John</td>

        <td>07868785831</td>

    </tr>

    <tr>

        <td>Miss</td>

        <td><i>Linda</i></td>

        <td>0141-2244-5566</td>

    </tr>

    <tr>

        <td>Master</td>

        <td>Jack</td>

        <td>0142-1212-1234</td>

    </tr>

    <tr>

        <td>Mr.</td>

        <td>Bush</td>

        <td>911-911-911</td>

    </tr>

</table>

出口按钮:

<input value="Export as CSV 2" type="button" onclick="$('#example1').table2CSV({header:['prefix','Employee Name','Contact']})">
