search data island

Tracey · Dec 9, 2003

I have code to navigate records held within an xml data island (data.xml)

function first(){
data.recordset.moveFirst();
}
function previous(){
if(data.recordset.absoluteposition>1)
data.recordset.movePrevious();
}
function next(){
if(data.recordset.absoluteposition <
data.recordset.recordcount)
data.recordset.moveNext();
}
function last(){
data.recordset.moveLast();
}

which works nicely.

However, what i need to do, is (when the user types in letters into an <input>) search the data island for nodes in which the name field starts with the letters typed in...
eg if user types "ice" I need to retrieve the "icehouse" node and the "icecream" nodes/records.

Can anyone here help me? I am not a Javascript programmer (and just learning about xml to boot), what i would like is something along the lines of

data.recordset.find(fieldname, 'string');

Take a look at this code, look especially at function doselect and button "select a page number"

Code:

<html>
<head>
  <!-- Template of XML Data Island, Author Ion Filipski -->
  <title>dynamic HTML with XML Data Island</title>
  <xml id=&quot;xmlmeetings&quot;>
    <?xml version=&quot;1.0&quot;?>
      <meetings>
        <meeting>
          <date>1/1/99</date><time>9:00</time><location>Munhen</location>
        </meeting>
        <meeting>
          <date>2/1/99</date><time>13:00</time><location>Bucharest</location>
        </meeting>
        <meeting>
          <date>3/1/99</date><time>14:30</time><location>NewYork</location>
        </meeting>
        <meeting>
          <date>3/1/99</date><time>14:30</time><location>Paris</location>
        </meeting>
        <meeting>
          <date>3/1/99</date><time>14:30</time><location>Beijing</location>
        </meeting>
      </meetings>
  </xml>
  <script language=&quot;JScript&quot;>
    var meetings;
    var meeting;
    var name;
    var i;
    var j;
    var currentPage = 0;
    var doc = document;
    meetings = xmlmeetings.documentElement.selectNodes(&quot;meeting&quot;);
    var x = 0;

    function doWriteHead()
    {
      meeting = meetings[x];
      var strHtml = &quot;&quot;;
      strHtml = &quot;meeting {&quot; + (x + 1) + &quot;}:<br/>&quot;;
      strHtml = strHtml + &quot;<table border=\&quot;1\&quot;>&quot;;
      for(i = 0; i < meeting.childNodes.length; i++)
      {
        strHtml = strHtml + &quot;\n<tr><td>&quot;;
        strHtml = strHtml + meeting.childNodes[i].nodeName;
        strHtml = strHtml + &quot;</td><td>&quot;;
        strHtml = strHtml + meeting.childNodes[i].text;
        strHtml = strHtml + &quot;</td></tr>&quot;;
      }
      doc.all.detail.innerHTML = strHtml;
    }
    function doNext()
    {
      if(x < (meetings.length - 1))x++;
      doWriteHead();
    }
    function doPrev()
    {
      if(x > 0)x--;
      doWriteHead();
    }
    function doSelect()
    {
      x = doc.all.pagenum.value;
      doc.all.pagenum.value = &quot;&quot;;
      doPrev();
    }
  </script>
</head>
<body id>
  press next or prev page to view meetings:<br/>
  <input type=&quot;button&quot; value=&quot;prev page&quot; onclick=&quot;javascript:doPrev();&quot;/>
  <input type=&quot;button&quot; value=&quot;next page&quot; onclick=&quot;javascript:doNext();&quot;/><br/>
  <input type=&quot;button&quot; value=&quot;select a page number&quot; onclick=&quot;javascript:doSelect();&quot;/>
  <input type=&quot;text&quot; id=&quot;pagenum&quot;/><br/>
  <p id = &quot;detail&quot;/>
</body>
</html>

so how then would you find the page if you asked the user to type in the first 3 letters of the meeeting.location instead of the page number?

no, place a number or meeting. There are five meetings, so choose from 1 to 5
