Re: [jQuery] cant append() form objects

Just a quick input on the PHP variables,

Here comes another one: Using the $str = "My string with an inline$variable. Oh no!"-syntax is generally thought of as a bad practice bymany PHP folks (including me). Therefor using something like:


$str = 'My string without an inline'.$variable.'. Yeah!';

is the mostly recommended choice out there. Oh and before I forget,another difference between the double quotes (") and single quotes (')strings is that in the single quotes ones you can not use specialcharacters like: "\n \t \r", etc. Those are only available in doublequoted string literals.

If you use double quotes this:
echo "$var"; will output the contents of $var
but using single quote
echo '$var'; vill output $var (not the contents of a variable)

Well, I finally got everything working using your method, although i dumped
the use of $ since php wanted to consider them as variables even when in
quotes and when using xajax addscript returns.  I am still puzzled why my
old method didn't work, but I am glad to have learned a new way of doing
things.  Now I am getting more and more locked and hooked into jquery!!
Hope I never have to go back.

I use $ in the variable name to remind me that it is a jQuery object. Like
naming a variable aForms if it contains an array.

The problem with your id example is that because tst.$form is a jQuery
object and not the DOM element itself. DOM elements have id properties,
jQuery objects do not. Try:
alert(tst.$form[0].id);

Thanks. That does seem to work when it stands alone.   I am having a hard

time making it work in my actual environment however.   This test is overly
simplified to what I actually need. I tried using your method but I am
missing something.  I am not sure I entirely understand the use of $ in
front of the ojbect name (like $layer).  Is that just a preference or does
the $ do something in jquery that I should be aware of? Given your code
below, I should be able to reference the form object like this

tst=new appLayer('Test'); //create layer and layer objects.

tst.$form // this is the form object
alert(tst.$form.id) // this should alert the id of the form.  right?

For some reason its not working that way.

Thanks again for your efforts.

Jeremy

I refactored your function to use jQuery:
function appLayer(id){
   //create layerbox
   this.$layer = $("<div id='" + id + "_layer'

class='layerbox'></div>").appendTo("#content");

   //create form
   this.$layer.append(this.$form = $("<form id='" + id + "_form' name='" +

id + "_form' action='index.php' method='post'></form>"));

   //create main div
   this.$main = $("<div id='" + id + "_main'

class='morebox'></div>").html("This box should get created,
but it doesnt because form didnt get
created").prependTo(this.$form);

}

Interestingly, when I tryed to use

this.$form.appendTo(this.$layer) it didn't work. Is this a
bug? Not sure. But this function worked for me.

After upgrading from 1.0.4 to 1.1.1 the following code no longer works.

Please tell me if there is a solution to this issue.

 $("#"+this.frm).prepend(main);
}
tst=new appLayer('Test');
</script>
</body>

The form object does not get created.  I don't have any problems

appending other objects such as divs, but the form object won't work
anymore.

It works fine in 1.0.4.  Try it out.

Thanks in advance.
