The page below is working absolutely fine...

What I am doing here is that:

On pressing the enter key on Text control (Red bolded) i am calling javascript functn which is calling send() from controller class.

controller class function is..

public PageReference send(){

 //some code

return null;

}

 this functn is redirecting on same page...

now other script function setFocusOnLoad() is making Text control to be focussed on page load....

when I use showHeader property of <apex:page> to "TRUE"...

all things run fine...

but as soon as i disable header i.e make showHeader property to "False"

cursor doesnot get focussed to Text control

<apex:page id="thePage" showHeader="true" sidebar="false" controller="Test">
<script>
function setFocusOnLoad() {

var txt=document.getElementById(text1)
    txt.value=''
  txt.focus()
}
</script>

<script type="text/javascript">
 
function callSend(e){

if(e){
e = e
} else {
e = window.event
}

if(e.which){
var keycode = e.which
} else {
var keycode = e.keyCode
}

if(keycode == 13) {
 

var send=document.getElementById(sendText)
            send.click()
           
            return false
}
else{
return true
}
}


</script>
<apex:form>
    <apex:inputTextarea id="messengerText" value="{!messageText}" readonly="true" cols="100" rows="10" disabled="{!visible2}"/><br>
        <apex:actionPoller action="{!refresh}" reRender="messengerText" interval="5"/>
   
   
 
   
        <apex:outputLabel value="Enter text here"/>
           <apex:inputTextarea id="Text" value="{!text}" cols="70" disabled="{!visible2}" onkeydown="callSend(event)"/><br>
   
           <script> var text1 = '{!$Component.Text}';</script>

   
   
           <apex:commandButton id="send" action="{!send}" value="Send"/>
        <script> var sendText = '{!$Component.send}';</script>
<apex:form>
</apex:page>

Plz tell me the solution of this...

because I don't want the header to be shown on my page and at the same time I want to focus Text control(TextArea) on page load..

Thank you

Hi...

I am trying to set focus to a specified textbox through its controller class(as it is requirement) ...

For this in asp we have like "Page.RegisterStartupScript()"...

for eg..

private void SetFocus(String controlID)
{
  // Build the JavaScript String
  System.Text.StringBuilder sb = new System.Text.StringBuilder();
  sb.Append("<script language='javascript'>");
  sb.Append("document.getElementById('");
  sb.Append(controlID);
  sb.Append("').focus()");
  sb.Append("</script>")
 
  // Register the script code with the page.
  Page.RegisterStartupScript("FocusScript", sb.ToString());
}

Is there any method in apex in Force.com to register a javascript on current page through apex code...

please reply asap...

Thank you!!!

Hello to all.....

well I am trying to use Ajax to refresh a control which is inside a table(HTML tags)...

like:

<table>

  <tr>

        <td><apex:inputTextArea id="TextArea" value="{!someText}"/></td>

        <apex:actionPoller action="{!refresh}" reRender="TextArea" interval="5"/>

  </tr>

</table>

when I use above code..my TextArea control doesnot refresh after 5 sec...

but if I remove the html tags only...then the code executes fine....

can someone clear me wether Ajax is supported within html tags or not...

and if not so what can I do to format(in tabular format) my visualforce page.
