我已经下载了用于将 HTML 表格转换为 excel 的 Javascript 函数。它将页面中的所有表格转换为excel,实际上我只需要将一个特定的表格转换为同样在按钮单击中的excel。但是下载的执行 Page 的 javascript 代码会自行加载。有人可以指导我如何使其成为功能以及特定表(给定表ID)

    <table id="testTable">
        <thead>
            <tr>
                <th>Name</th>
                <th>ACP</th>
                <th>OEMCP</th>
                <th>Unix<br>
                    NT 3.1</th>
                <th>Unix<br>
                    NT 3.51</th>
                <th>Unix<br>
                    95</th>
            </tr>
        </thead>
    </table>
    <table id="testTable1">
        <thead>
            <tr>
                <th>Name</th>
                <th>ACP</th>
                <th>OEMCP</th>
                <th>Windows<br>
                    NT 3.1</th>
                <th>Windows<br>
                    NT 3.51</th>
                <th>Windows<br>
                    95</th>
            </tr>
        </thead>
    </table>
    <script type="text/javascript">
    (function(){
      var cache = {};

      this.tmpl = function tmpl(str, data){
        // Figure out if we're getting a template, or if we need to
        // load the template - and be sure to cache the result.
        var fn = !/\W/.test(str) ?
          cache[str] = cache[str] ||
            tmpl(document.getElementById(str).innerHTML) :

          // Generate a reusable function that will serve as a template
          // generator (and which will be cached).
          new Function("obj",
            "var p=[],print=function(){p.push.apply(p,arguments);};" +

            // Introduce the data as local variables using with(){}
            "with(obj){p.push('" +

            // Convert the template into pure JavaScript
            str.replace(/[\r\t\n]/g, " ")
                  .split("{{").join("\t")
                  .replace(/((^|}})[^\t]*)'/g, "$1\r")
                  .replace(/\t=(.*?)}}/g, "',$1,'")
                  .split("\t").join("');")
                  .split("}}").join("p.push('")
                  .split("\r").join("\\'")
                  + "');}return p.join('');");

        // Provide some basic currying to the user
        return data ? fn( data ) : fn;
      };
    })();

    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>{{for(var i=0; i<tables.length;i++){ }}<table>{{=tables[i]}}</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(tableList, name) {
            if (!tableList.length>0 && !tableList[0].nodeType) table = document.getElementById(table)
            var tables = [];
            for(var i=0; i<tableList.length; i++){
              tables.push(tableList[i].innerHTML);
            }
            var ctx = {worksheet: name || 'Worksheet', tables: tables};
            window.location.href = uri + base64(tmpl(template, ctx))
        }
    })();        
    tableToExcel(document.getElementsByTagName("table"),"one");
    </script> 

从上面的代码中,我只需要“testTable” excel 导出。此外,当我执行此 javascript 时,浏览器会卡住

tableToExcel(document.getElementsByTagName("table"),"one");

这是你的关键线!

你给它一个表格列表和一个新工作表的名称。

如果你只想要一个:

function expTable(tbl)
{
     var tables = [];
     tables.push(tbl);
     tableToExcel(tables,"myTableExcelWorkbook");
}

使用它运行它expTable(document.getElementById(tableId));
