[startsmart]

Hi
This is first time to write and alse it is first time to show this site

my problem is i need to pass value from any input type like text for example

to hidden field
I tried to make a function but it does not work


function hdate(){
var m,x,y,z;
x=document.frm1 .s1.value;
y=document.frm1 .s2.value;
z=document.frm1 .s3.value;
m=x+y+z;
return m;
}


and i called it using that code

<input type="hidden" name="hiddenFie ld" value="hdata()"/>

thank you in advance

You need to write the value of the hidden field from javascript something like

function hdate(){
  var m,x,y,z;
  x=document.frm1.s1.value;
  y=document.frm1.s2.value;
  z=document.frm1.s3.value;
  m=x+y+z;

  document.frm1.hiddenField.value = m;
}

The value attribute is text not javascript which is why what you wrote doesn't work. You will have to work out a good time to call this function, from the onClick handler of a button or the onSubmit handler of the form may be.

Passing value from Textbox to HiddenInputFiel d

Hi,First
<input type="hidden" id="myhidden" runat="server" />
in ur .aspx or .ascx page

suppose i had a textbox ,from which i want to initilize this hiddenInputFiel d,i will use the typical onBlur() event of the textbox,so when the focus is lost from Textbox i will save the data in hiddenfiled.
<asp:TextBox ID="mytxt" onBlur="popfiel d()" runat="server" />

my sample popfield() function will be like

<script language="javas cript" type="text/javascript">

function popfield()
{
document.getEle mentById('myhid den').value =
$get('<%=mytxt. ClientID %>').value;
//alert(cument.ge tElementById('m yhidden').value );
}
</script>
