Hi,
You can try this code snippet. I may be helpful. - <html>
-
<head>
-
<title>Country Selection</title>
-
<script language="javascript">
-
var Country = null;
-
function init()
-
{
-
var numCountry = 2;
-
var oStateSlct = document.CountrySelect.Function;
-
Country = new Array(numCountry+1);
-
oStateSlct.options[0] = new Option("Please select a Country Type", "-1");
-
Country[0] = new Array(0);
-
oStateSlct.options[1] = new Option("Country1", "1");
-
Country[1] = new Array(1);
-
Country[1][0] = new Option("State1", "-1");
-
oStateSlct.options[2] = new Option("Country2", "2");
-
Country[2] = new Array(2);
-
Country[2][0] = new Option("State1", "-1");
-
Country[2][1] = new Option("State2", "0");
-
-
}
-
-
function fillUpSelectControl(srcCntrl,targetCntrl,selectOptions)
-
{
-
var slctIndx = srcCntrl.options.selectedIndex;
-
for( i=0; i<targetCntrl.options.length; i++ )
-
targetCntrl.options[i] = null;
-
-
var newOptions = selectOptions[slctIndx];
-
for( i=0; i<newOptions.length; i++ )
-
targetCntrl.options[i] = new Option( newOptions[i].text, newOptions[i].value );
-
targetCntrl.options[0].selected = true;
-
}
-
</script>
-
</head>
-
<body onload="init();">
-
-
<form name="CountrySelect" >
-
<select NAME="Function" onChange="fillUpSelectControl(this,this.form.StateType,Country)">
-
</select>
-
<select name="StateType">
-
</select>
-
</form>
-
-
</body>
-
</html>
hii
thanks for the snippet , i've been doin this project using Servlets,JSP and JDBC.
I dont know much about scripting how can i connect to db using this
anil
You would probably have to use AJAX, DOM you can find help for that all over google good examples.
Will this code work if yes can i get the value of hidden Name to my jsp page!!
function madeSelection(selObj)
{
var selectedValue = selObj.options[selObj.selectedIndex].value;
//document.Name.value = "ANIL";
document.hiddenName.value = selectedValue;
document.write(document.hiddenName.value);
}
html tag------
input type=hidden name=hiddenName
Will this code work if yes can i get the value of hidden Name to my jsp page!!
function madeSelection(selObj)
{
var selectedValue = selObj.options[selObj.selectedIndex].value;
//document.Name.value = "ANIL";
document.hiddenName.value = selectedValue;
document.write(document.hiddenName.value);
}
html tag------
input type=hidden name=hiddenName
No. This will not work.
The culprit line is - document.hiddenName.value = selectedValue;
which should be - document.formName.hiddenName.value = selectedValue;
or -
-
document.forms['formName'].hiddenName.value = selectedValue;
-
Where formName is the name of the form on which the hidden input is.
Yes you can get to this value in a jsp using - String name = request.getParameter("hiddenName");
