  • 0

I’m trying to get a form (provided in HTML form from a callback) after adding it to already present content. Adding it presents no issues and the form shows up properly. It is provided (as HTML) by the callback with the id= (placeid + “commentinput”) and added to the page. However, trying to do $(placeid + “commentinput”) does not return a proper jQuery element (for example, the alert(form.tagName) is supposed to return “FORM” but is always undefined instead).

function click_comment1(urlstr, id) { $.ajax({url: urlstr,success: success_on_get_form(urlstr, id)}); }
function success_on_get_form(urlstr, placeid) {
return function (val) {
    $("#" + placeid + "newcomment").html(val.replace("comments_body","body"));
    $("#pup").html($("#" + placeid + "comments").html());
    var form = jQuery("#" + placeid + "commentinput");
    var func = submit_comment(urlstr, placeid);
    alert(form.id);
    form.bind('submit',func);
} }

I’ve tried every other form of selection I know of at this point (basically, .children(). I’m new to jQuery). I’ve been hacking at this problem in various forms helplessly for 4 hours now. I’d appreciate any help, thank you.

<form action="" enctype="multipart/form-data" id="1commentinput" method="post">...</form>

This is the return from the callback; the middle part is omitted for space.

The #pup element seen is a popup as provided with this.

“#” + placeid + “newcomment” is a div within “#” + placeid + “comments”. These first 2 calls executing seemingly properly and render the callback provided form in the popup as desired.

The intent with all of this is to add a form to this popup, which is then used to make a second callback.

    Your problem most likely boils down to the fact that you are using invalid character to start your element ID..

    Change it to start with a valid character and it should work.

    http://www.w3.org/TR/html4/types.html#type-id

    ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens (“-“), underscores (“_”), colons (“:”), and periods (“.”).
