Question

I have a page in which I want to find all datetime values.

I want to find all datetime values and convert them from Hijri datetimes to standard datetimes.

How can I find datetime value with javascript and change it?

For example:

I want this code in html

<td class="ms-vb2"><nobr>18/02/1391 14:07</nobr></td>

I want to find the datetime value (18/02/1391 14:07), then change it to (14/08/2012 10:15) with javascript.

Edit

I use this code and find all date value

var re =  /[0-3]\d\/[01]\d\/\d{4}/g;
var dates = $("body").text().match(re);

How to replace it to new date???

Answer 1

You are recurse over all text nodes starting from a particular element using the following (uses mplungjan’s a simple regular expression):

// Recursively replace text in text nodes of elements
function replaceText(el) {

  var node, nodes = el.childNodes;
  var re = /[0-3]\d\/[01]\d\/\d{4} [012]\d:[012]\d/g;
  var t;

  for (var i=0, iLen=nodes.length; i < iLen; i++) {
    node = nodes[i];

    // Replace content of text nodes
    if (node.nodeType == 3) {
      t = node.data.match(re);

      // See if has a date
      if (t) {

        // Iterate over members of t, replacing Hijri dates with Gregorian dates
        // convertDate should be a function to do the conversion
        for (var j=0, jLen=t.length; j<jLen; j++) {
          node.data = node.data.replace(t[j], convertDate(t[j])); 
        }
      }

    // Recurse over elements to get at child text nodes
    } else if (node.childNodes) {
      replaceText(node);
    }
  }
}

If the intention is to do the entire document, pass it the body element.
