Thanks for the response, by the way here is the code i.e. a FORM tag which i am generating from an DynamicObject(java class) i will be passing this generated FORM to an Javascript variable

<FORM name="vcc_form" id="vcc_form" class="vcc_form_class">
<fieldset style="border:blue solid 1px"><legend id="legend_vcc">
<b><font color="#0000FF">VCC</font></b></legend><div align= "center">
<label for="vcc.vcc_number_input_text"><b>VCC Number:</b></label>
<input type="text" name="vcc.vcc_number_input_text" value="0.38" id="vcc.vcc_number_input_text" class="vcc.vcc_number_input_text_class ">
</input>
<br>
<label for="vcc.vcc_type_input_text"><b>VCC Type:</b></label>
<input type="text" name="vcc.vcc_type_input_text" value="ubr" id="vcc.vcc_type_input_text" class="vcc.vcc_type_input_text_class ">
</input>
<br>
<br>
<input type=submit value="create" name=create_ vcc>
<input type=submit value="update" name=update_vcc>
<input type=submit value="delete" name=create_ vcc>
<input type=submit value="search" name=update_vcc>
<br><br></div> </fieldset></FORM>

Based on some values , but if i print using

System.out.println(str);

this will work but if i pass that too

document.getElementById("").innerHTML = "str";

I am getting a error saying Expected ";"

Let me know if i need to do any delimitation for Form attributes

Thanks

id you leave
document.getElementById("").innerHTML = "str";
id("") empty on purpose?...just curious

[gnanesh]

this is what i am doing :-

var str = <%=value%>; // this i will get from DynamicObject class

alert(str); //
document.getElementById('displayForm').innerHTML = "<%=value%>";

"displayForm" is the id value of an DIV tag,

Let me know about this

I did the same way , but don't know why i am getting this kind of problem saying "Line xxx
"Error:Expected ';'

Let me know this is what i am doing now :-

var str = '<%=value%>';
alert(str);
document.getElementById('displayForm').innerHTML = "str";


To the var str i am passing the '<form>
rest goes here----
</form>'

and don't know why i am getting this kind of problem

This piece giving lot of troubles, As i need this to be done today itself

Thanks & Regards

Well first of you need to take a look at the code I posted/link I posted.

You'd notice few things.
You can only access document.getElementById once document is loaded.Therefore you need to do perform that corm creation once the page loads and that you can do in onload event of the body tag..take a good look at code of the link I posted for you above...

I found out some thing from the resulted string i.e from

<%=value%>

when i pass this value to the javascript var like

var str = "<%=value%>;

i was not able to display because of some ending quotes when i generate an HTML out of DynamicObject , If i do like this below

" <FORM name='vcc_form' id='vcc_form' class='vcc_form_class'><fieldset style='border:blue solid 1px'><legend id='legend_vcc'><b><font color='#0000FF'>VCC</font></b></legend><div align='center'>"+
" <label for='vcc.vcc_number_input_text'><b>VCC Number:</b></label><input type='text' name='vcc.vcc_number_input_text' value='0.38' id='vcc.vcc_number_input_text' class='vcc.vcc_number_input_text_class '></input>"+
" <br> <label for='vcc.vcc_type_input_text'><b>VCC Type:</b></label><input type='text' name='vcc.vcc_type_input_text' value='ubr' id='vcc.vcc_type_input_text' class='vcc.vcc_type_input_text_class '></input>"+
" <p><input type=submit value='create' name=create_vcc> "+
" <input type=submit value='update' name=update_vcc> "+
" <input type=submit value='delete' name=delete_vcc> "+
" <input type=submit value='search' name=search_vcc> "+
" <br><br></div> </fieldset></FORM> ";

It does work good, I really don't know how to separate these in my DynamicObject,

Let me know your suggestions
