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">

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.
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();
