Validate list box

[rashmi_k28]

Hi,

 

I tried to validate the List box as shown below. But it is not working. Please  tell me what is the problem.

What I feel is  may be because of the query string with file name. So how can I solve this problem

 

 

 

 

<script>
function validate(){
        if(document.searchType.src_type.value == 'topn'){
         if((document.searchType.os.value == '--') && (document.searchType.type.value == '--')){
          alert("Select Criteria");
                document.searchType.os.focus();
          return false;
                }
        }
}
</script>

 

<form id=searchType name=searchType method="get" onSubmit="return validate();" action="<?=$_SERVER['PHP_SELF']?>">
        <div style="width:980px; top:20px;" align="center"><label><font size="4" color="#006699" face="Arial">SEARCH</font></label></div>
        <div style="width:980px; top:20px;" align="center">
        <table border="0" cellpadding="0" cellspacing="8">
          <tr>
                <td><a href=search.php?src_type=res>Resource</a></td>
                <td><a href=search.php?src_type=soft>Software</a></td>
                <td><a href=search.php?src_type=topn>Top N</a></td>
          </tr>
        </table>

    </form>

        <hr>
<?
   if(isset($_GET["src_type"])){
        $src_type = $_GET["src_type"];
        echo "<form id=searchRule  method=get action=searchResult.php>";
        echo "<input type=hidden name=src_type value=$src_type>";
        echo "<input type=hidden name=st_index value=0>";
        echo "<input type=hidden name=rpp value=20>";


eif("topn" == $src_type){
?>
         <div style=width:760px align=center>
        <table border=0 cellpadding=0 cellspacing=8>
          <tr>
            <td align="left"><label><font size=4 color="#006699" face="Arial">TopN Search </font></label></td>
          </tr>
        </table>

        </div>


        <div style=width:980px align=center>
        <table border=0 cellpadding=0 cellspacing=8>
          <tr>
            <td align="left"><label><font color="#006699" face="Arial">Operating System </font></label></td>
            <td align=left>
                <select id="os" name='os'>
                <option value="--" selected>--
                <option value="AIX">AIX
                <option value="Linux">Linux
                <option value="Solaris">Solaris
                </select>
            </td>
          </tr>
          <tr>
        <td align="left"><label><font color="#006699" face="Arial">Category</font></label></td>

            <td align="left"><select id="type" name="type">
                <option value="--" selected>--
                <option value="free">Free Memory

            <option value="tot_mem">Total Memory

            <option value="cpu_speed">CPU Speed
            <option value="no_of_processors">No. Of CPUs
            </select>

            </td>

1) Number one your closing you form tag on top </form> please close it after the select box

2) changed onSumbit="return validate();" to onsubmit="return validate(this)"

3) next changed the function as follows

 

<script>
function validate(f){
        if(f.src_type.value == 'topn'){
         if((f.os[f.os.selectedIndex].value == '--') && (f.type[f.type.selectedIndex].value == '--')){
          alert("Select Criteria");
                f.os.focus();
          return false;
                }
        }
}
</script>

 

hope its helpful
