JavaScript question...simple to anyone who know JS

**Wokawidget** · Jun 9th, 2005, 08:26 AM

I have a function:

Code:

function RebuildStartTimeDropDownCallBack()
	{
		var StartTimeIndex = document.main.StartTime.selectedIndex
                          'do some code
		document.main.StartTime.selectedIndex = StartTimeIndex
	}

However, I don't want to store, and restore the index.
I'd like to get the item data, and then select the combo item that has the same item data that I stored after I have done "Some other code". Item data is unique from a DB (Primary key ID)

Urgh I dont know any JS but I'll try to help

Could you maybe do this

Code:

function RebuildStartTimeDropDownCallBack()
	{
                var StartTimeData = document.main.StartTime.value
                          'do some code
                for (i=0, document.main.StartTime.length, i++) //Dunno about the .length
                    if (document.main.StartTime.thing[i] == StartTimeData) {
                        /* The .thing obviously you replace with whatever the JS
                            equivalent of VB's .List(i) would be */
		        document.main.StartTime.selectedIndex = i
                    }
                }
	}

? I know thats probably useless, I'm no good with Javascript.

<html>
  <head>
  <meta http-equiv="content-type" content="text/html; charset=windows-1250">
  <meta name="generator" content="PSPad editor, www.pspad.com">
  <title></title>
  <script>
  function changeIt(){
    //select the item with option value of 3 ie this will be you DB PK
    document.frm.sel.options.value = 3;
  }
  </script>
  </head>
  <body>
  <form name="frm">

ok dokey this seems to work in both (if this is what your looking for not entirely sure)

Code:

<html>
  <head>
  <meta http-equiv="content-type" content="text/html; charset=windows-1250">
  <meta name="generator" content="PSPad editor, www.pspad.com">
  <title></title>
  <script>
  function changeIt(){
    //select item with option value of c
    document.frm.sel.value = "c";
  }
  </script>
  </head>
  <body>
  <form name="frm">
    <select name="sel">
      <option value="a">one</option>
      <option value="b">two</option>
      <option value="c">three</option>
      <option value="d">four</option>
      <option value="e">five</option>
    </select>
    <input type="button" value="click" onclick="changeIt();">
  </body>
</html>
