HTML表格到Excel Javascript

Coo*_*rab 28 html javascript excel html-table

我正在尝试使用此脚本将html表保存到Excel文件,并且它工作正常,但它没有以正确的名称出现,而是使用随机字符串.我不明白为什么.

我叫它:

<input type="button" onclick="tableToExcel('tablename', 'name')" value="Export to Excel">

window.location.href = uri + base64(format(template, ctx))
}

您可以使用download现代browsera支持的属性作为a锚元素.首先通过添加不可见的锚来修改HTML:

<a id="dlink"  style="display:none;"></a>

<input type="button" onclick="tableToExcel('tablename', 'name', 'myfile.xls')" value="Export to Excel">

另请注意,函数调用tableToExcel现在具有第3个参数 - 您可以在其中指定文件名.

现在使用原始函数的这个修改代码:

var tableToExcel = (function () {
        var uri = 'data:application/vnd.ms-excel;base64,'
        , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
        , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
        , format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }
        return function (table, name, filename) {
            if (!table.nodeType) table = document.getElementById(table)
            var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }

            document.getElementById("dlink").href = uri + base64(format(template, ctx));
            document.getElementById("dlink").download = filename;
            document.getElementById("dlink").click();

        }
    })()

注意最后3个代码行:不是将URL分配给窗口 - 而是将其分配给新锚,然后使用new download属性强制下载为给定文件名,然后click()是锚的简单调用方法.

试试看.

  • 真棒!该名称有效,但现在我收到此错误:`您尝试打开的文件'name.xls'与文件扩展名中指定的格式不同.在打开文件之前,请验证文件是否已损坏且来自受信任的来源 (2认同)
  • 这是正常的,你之前也应该这样做.发生这种情况是因为文件不是真正的Excel,而是伪装的XML.但是在那个警告之后,文件应该打开OK.您可以使用文件扩展名来尝试摆脱警告(例如将其更改为.XML等) (2认同)

上面的3条代码行在我的情况下不起作用,但是在这里找到了我希望能有所帮助的代码。

function tableToExcel(table, name, filename) {
        let uri = 'data:application/vnd.ms-excel;base64,', 
        template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><title></title><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--><meta http-equiv="content-type" content="text/plain; charset=UTF-8"/></head><body><table>{table}</table></body></html>', 
        base64 = function(s) { return window.btoa(decodeURIComponent(encodeURIComponent(s))) },         format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; })}
        
        if (!table.nodeType) table = document.getElementById(table)
        var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}

        var link = document.createElement('a');
        link.download = filename;
        link.href = uri + base64(format(template, ctx));
        link.click();
