hi,
i have the following function which is not working for me:
function uploadimg (theform,ajaxAction,ajaxTarget){
var imgDesc = theform.getInputs(''page1'',
''text'',''imgDesc'');
alert(imgDesc[0]);
defaultAction=theform.action;
defaultTarget=theform.target;
theform.action=ajaxAction;
theform.target=ajaxTarget;
theform.submit(); //Submit the form.
//Then display a loading message to the user.
setStatus ("Please wait while your image
uploads...","showimg");
theform.action=defaultAction;
theform.target=defaultTarget;
}
the problem i''m having is that I can''t access the value of the
image
description field in my form which looks like:
<input type="text" name="imgDesc"
size="40"/>
the alert above displays ''undefined'' or is just blank if i do
alert(imgDesc);
can anyone see what i''m doing wrong?
thanks,
Luke

What''s wrong with: var imgDesc = theform.imgDesc; or var imgDesc = theform.elements[''imgDesc'']; to get a reference to the element directly?> alert(imgDesc[0]); > defaultAction=theform.action; > defaultTarget=theform.target; > theform.action=ajaxAction; > theform.target=ajaxTarget; > theform.submit(); //Submit the form. > //Then display a loading message to the user. > setStatus ("Please wait while your image uploads...","showimg"); > > theform.action=defaultAction; > theform.target=defaultTarget; > } > > the problem i''m having is that I can''t access the value of the image > description field in my form which looks like: > > <input type="text" name="imgDesc" size="40"/> > > the alert above displays ''undefined'' or is just blank if i do > alert(imgDesc); > > can anyone see what i''m doing wrong?How do you pass a reference to the form? Prototype.js extends the built-in form element in Firefox (and others that support element extensions) but not for IE - you must do it yourself. It will work if you change as noted above, or extend the form element before that. But why not just use ordinary old - theForm.elements[''imgDesc''] - ? -- Rob --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

thanks for the reply. i was doing it wrong. this syntax worked for me in the end: var imgDesc = Form.getInputs(theform, ''text'',''imgDesc''); var imgTitle = Form.getInputs(theform, ''text'',''imgTitle''); but i actually realised i could do the processing i needed in php so am not using prototype to do this.
