问题描述

我有4列的表，其中每列包含文本字段和按钮，每行的末尾由编辑和删除按钮组成。
我想将表导出为ex​​cel格式，但是当我做文本字段和列标题的按钮，编辑和删除按钮也被导出到我不想要的excel文件。
任何人都可以告诉我我在javascript中犯了什么错误。



这是我从网上得到的jquery代码（ http://jsfiddle.net/insin/cmewv/ ）

 < script type =text / javascript> 
 var tableToExcel =（function（）{
 var uri ='data：application / vnd.ms-excel; base64，'
，template ='< html xmlns：o =urn ：schemas-microsoft-com：office：officexmlns：x =urn：schemas-microsoft-com：office：excelxmlns =http://www.w3.org/TR/REC-html40>< ; head><！ -  [if gte mso 9]>< xml>< x：ExcelWorkbook>< x：ExcelWorksheets>< x：ExcelWorksheet>< x：Name> {worksheet} X：名称>< X：WorksheetOptions>< X：DisplayGridlines />< / X：WorksheetOptions>< / X：ExcelWorksheet>< / X：ExcelWorksheets>< / X：ExcelWorkbook>< / XML> ;<！[endif]  - >< / head>< body>< table> {table}< / table>< / body>< / html>'
，base64 =函数{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）{
 if（！table.nodeType）table = document.getElementBy Id（table）
 var ctx = {worksheet：name || 'worksheet'，table：table.innerHTML} 
 window.location.href = uri + base64（format（template，ctx））
} 
}）（）
< /脚本>

我的HTML代码如下

 < TABLE id =table_idclass =displayalign =Centerborder =1pxwidth =80％> 
< thead>

解决方案

尝试设置标签，具有按钮和编辑文本有一个类来识别这个domss例如：Class ='ignore'。
克隆之后，这个yout表和克隆表删除了所有设置了类的dom。
删除这个dom后，克隆表将导出到excel。

尝试这个。



js脚本

 return window.btoa（unescape（enc odeURIComponent（s））
}，format = function（s，c）{
 return s.replace（/ {（\w +）} / g，function（m，p）{
 return c [p]; 
}）
} 
返回函数（表，名称）{
 if（！table.nodeType）
 table = document.getElementById（table）; 
 var cln = table.cloneNode（true）; 
 var paras = cln.getElementsByClassName（'ignore'）; 
 
 while（paras [0]）{

} 
 var ctx = {
工作表：名称|| '工作表'，
表：cln.innerHTML 
} 
 window.location.href = uri + base64（format（template，ctx））
} 
}） （）;

I have table with 4 columns where every column includes text field and button and at the end of every row consists of edit and delete button. I want to export the table into excel format but when I do the text field and button at the column header and edit and delete button are also getting exported into excel file which I dont want. Can any one tell me where I am making the mistake in javascript, please.

Here is my jquery code which I got it from net (http://jsfiddle.net/insin/cmewv/)

<script type="text/javascript">
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) {
    if (!table.nodeType) table = document.getElementById(table)
    var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
    window.location.href = uri + base64(format(template, ctx))
  }
})()
</script>

my HTML code as follows 

<TABLE  id="table_id" class="display" align="Center" border="1px" width="80%">
        <thead>
        <tr>

                </form></td>    
        <%} %>
            </tr>   

            </tbody>
    </TABLE>

解决方案

Try set tag that have a buttons and a edit text with a class to indentify this dom´s ex.: Class='ignore'. After this clone this yout table and in table cloned remove all dom's that have class that you seted. After removed this dom´s pass the cloned table to function that will export to excel.

Edit -------

Try this.

js script

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) {
            if (!table.nodeType)
                table = document.getElementById(table);
            var cln=table.cloneNode(true);
            var paras = cln.getElementsByClassName('ignore');

            while(paras[0]) {
                paras[0].parentNode.removeChild(paras[0]);
            }
            var ctx = {
                worksheet : name || 'Worksheet',
                table : cln.innerHTML
            }
            window.location.href = uri + base64(format(template, ctx))
        }
    })();
