adding dynamic controls in struts2

[rohit chavan]

Hi,

We are currently migrating one web application from struts 1.x to struts2.
In which, we have a functionality where we add a row of controls dynamically, in struts1.x what we did was
1. add a new "div"
2. create and concatenate html code using strut's <html:select/> tag
3. rewrite the innerHTML of that div with javascript

this can be done for multiple rows as well.

here is the code snippet for the same
var fieldsfromdatabase = '<html:select name="InsertForm" property="jspfield"><logic:iterate id="ld_list1" name="InsertForm" property="fieldList"><option value=<bean:write name="ld_list1" property="field" />><bean:write name="ld_list1" property="field" /></option></logic:iterate></html:select>'; var conditions='<html:select name="InsertForm" property="condition"><option value="=">EQUAL TO</option><option value="<>">NOT EQUAL TO</option><option value=">=">GREATER THAN & EQUAL TO</option><option value="<=">LESS THAN & EQUAL TO</option><option value="<">LESS THAN</option><option value=">">GREATER THAN</option></html:select></td>'; newdiv.innerHTML = '<tr><td>'+fieldsfromdatabase+' '+conditions+'<input type="text" name ="value"/></td></tr><a rel="nofollow">Remove</a>'; document.getElementById('ExpandThis').appendChild(newdiv);

this way it was working fine.

but when we are trying the same with <s:select /> in struts2like this,

// var fieldsfromdatabase = '<s:select label="*" key="Match" headerKey="1" headerValue="-- Please Select --" list="#{\'01\' : \'Receipts\'}" ></s:select>';

we are getting 'Unterminated String constant' error in javascript!

we have already tried a number of combinations on this, to check if we are doing something wrong with the escape characters.

But as per my understanding, this is related to interpretation of the var by struts2.

awaiting replies on the same,

Thanks,
Rohit

Look at the source html it might help you.. as struts 2 renders the s:select tag into multiple tags... label, table etc..

look here
