repetitive instruction, more efficient solution?

stolte · November 27th, 2007, 01:41 PM

Is there a more efficient way to build a pulldown menu where the selected option depends on a parameter passed in? I have defined a template, but it seems that there must be a more efficient way to go.

Currently, the template is:

<xsl:template name="hour_pulldown">

<xsl:param name="i"/>

<select name="select">
    <option><xsl:if test="$i = 0"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>00</option>
    <option><xsl:if test="$i = 1"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>01</option>
    <option><xsl:if test="$i = 2"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>02</option>
    <option><xsl:if test="$i = 3"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>03</option>
    <option><xsl:if test="$i = 4"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>04</option>
    <option><xsl:if test="$i = 5"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>05</option>
    <option><xsl:if test="$i = 6"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>06</option>
    <option><xsl:if test="$i = 7"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>07</option>
    <option><xsl:if test="$i = 8"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>08</option>
    <option><xsl:if test="$i = 9"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>09</option>
    <option><xsl:if test="$i = 10"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>10</option>
    <option><xsl:if test="$i = 11"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>11</option>
    <option><xsl:if test="$i = 12"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>12</option>
    <option><xsl:if test="$i = 13"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>13</option>
    <option><xsl:if test="$i = 14"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>14</option>
    <option><xsl:if test="$i = 15"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>15</option>
    <option><xsl:if test="$i = 16"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>16</option>
    <option><xsl:if test="$i = 17"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>17</option>
    <option><xsl:if test="$i = 18"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>18</option>
    <option><xsl:if test="$i = 19"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>19</option>
    <option><xsl:if test="$i = 20"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>20</option>
    <option><xsl:if test="$i = 21"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>21</option>
    <option><xsl:if test="$i = 22"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>22</option>
    <option><xsl:if test="$i = 23"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>23</option>
    <option><xsl:if test="$i = 24"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>24</option>
</select>
</xsl:template>

Are you using XSLT 1.0 or 2.0?

stolte · November 27th, 2007, 01:49 PM

Sorry for not clarifying that in my previous post.

I am using XSLT 2.0.

Martin Honnen · November 27th, 2007, 02:03 PM

Then you should be able to code it easily e.g.

Code:

<xsl:template name="hour_pulldown">

<xsl:param name="i"/> 
<select name="select">
  <xsl:for-each select="0 to 24">
    <option>
      <xsl:if test=". eq $i">
        <xsl:attribute name="selected" select="'selected'"/>
      </xsl:if>
      <xsl:value-of select="if (. lt 10) then concat('0', .) else ."/>
    </option>
  </xsl:for-each>
</select>
</xsl:template>

Thank you. Definitely more efficient with 2.0.
