parameter from JScript to Asp.netHi there,
Can anyone tell me a way to pass parameters from java script to ASP.net (VB.net)? Thanks "luke" <talktomyfri***@hotmail.com> wrote in message What are you trying to achieve with this...?news:%23Qe1ATMzGHA.1256@TK2MSFTNGP02.phx.gbl... > Can anyone tell me a way to pass parameters from java script to ASP.net In the application's html, the code is:
<SCRIPT language="JAVASCRIPT" ..... .......... function update_temperature(x, y) { document.Form1.txtTemperatureX.value= x; document.Form1.txtTemperatureY.value= y; } ........ I can pass the values to txtTemperatureX and Y (only visible) in server section, however when I click on one button which suppose to pick up the value of txtTemperatureX and Y, but it is not at all,. Simply not updating the page and change the old value from txtTemperatureX and Y. If any help would be appreciated. Thanks. I try to find a better way to pass parameters Show quote "Mark Rae" <mark@markNOSPAMrae.com> wrote in message news:O5UKHeMzGHA.4648@TK2MSFTNGP04.phx.gbl... > "luke" <talktomyfri***@hotmail.com> wrote in message > news:%23Qe1ATMzGHA.1256@TK2MSFTNGP02.phx.gbl... > >> Can anyone tell me a way to pass parameters from java script to ASP.net > > What are you trying to achieve with this...? >

In which case, I wonder if you are populating the values of the two textboxes every time the page loads... If this is the case, then the form fields will always have their original values e.g. protected void Page_Load(object sender, System.EventArgs e) { // fetch data // populate form fields } should be protected void Page_Load(object sender, System.EventArgs e) { if (!Page.IsPostback) { // fetch data // populate form fields } } I did use the approach as you said, however it seems the java script in html
didn't refresh the page at all, or somehow it postback to the old value but it visually looks like the new value has been changed.

You have few options: 1) pass it as parameter in url while redirecting with location.replace() 2) pass it as field in form (most likely hidden field) 3) pass it in cookie which is modified from js. -- PP Hi,
