我有一个我正在尝试读取的 excel 文件,然后在下拉列表中显示标题的值。我的 excel 文件中的第一行包含所有值(标题名称)。

我使用了下面的代码,但结果是所有标题名称都出现在带有逗号的单行中。我希望将标题分开,以便它会出现在下拉列表中,其中很多<option>,而不是单个<option>. 我怎么做?

    <!-- Read the header values from excel -->
    <cfset spreadsheet = "uploads/spreadsheet.xlsx">

    <cfspreadsheet action="read" headerrow="1" src="uploads/spreadsheet.xlsx" query="excelHeader" rows="1" />

    <cfset excelHeaders = excelHeader.columnList>

    <!-- Display the header names as a dropdown -->
    <select name="id_headers">
        <option>
            #excelHeaders#
        </option>
    </select>

你可以试试这个代码;

<!--- create new spreadsheet and populate with sample data --->
<cfset theSheet = SpreadsheetNew("Expenses")>
<cfset SpreadsheetSetCellValue(theSheet,"column1",1,1)> 
<cfset SpreadsheetSetCellValue(theSheet,"column2",1,2)>
<cfset SpreadsheetSetCellValue(theSheet,"column3",1,3)>
<cfset SpreadsheetSetCellValue(theSheet,"column4",1,4)>

<!--- Write the spreadsheet to a file, replacing any existing file. ---> 
<cfset pathToFile = GetDirectoryFromPath(GetCurrentTemplatePath()) & "newSpreadsheet.xls">
<cfspreadsheet action="write" filename="#pathToFile#" name="theSheet" overwrite=true>

<!--- Read spreadsheet into query object ---> 
<cfspreadsheet action="read" headerrow="1" src="#pathToFile#" query="excelHeader" rows="1">

<!--- Display the header names as a dropdown --->
<cfoutput>
<select name="id_headers">
<cfloop list="#excelHeader.columnList#" index="option">
    <option>#option#</option>
</cfloop>
</select>
</cfoutput>

您可以在trycf中运行此代码段
