如何使用HTML或javascript将变量传递到action属性以进行下载（按钮/链接），

Question

<xsl:template name ="DLFiles">
  <xsl:variable name ="FilePath" select="@FilePath"/>    
  <form method="get" action="$FilePath">
        <button type="submit">Download</button>

(FilePath comes from a SQL column)

when $FilePath is a hardcoded (local) file path, this works great. However when a variable is passed, the download does not work (the file path can not be found, cant get data(FilePath column data) from SQL)

is there something I can change in the above code to make this work correctly in this instance?

Answer 1

You can use Attribute Value Templates here if you want to use a variable in an attribute

 <form method="get" action="{$FilePath}">

The curly braces indicate an expression to be evaluated, not output literally.
