#13471 — jquery ,get the id of the input in order to delete input row?

Below is the delete function,  but I don't know how to capture the
input id.  I am not using an html table for the data.  The todo items
are added dynamically through AJAX.  How to select which id has the
button delete clicked and remove that row ?  The html is in a section
and is an unordered list with a checkbox on left side, the user input,
and the delete button on the right.  I want to delete the row when
delete button is clicked.  See the HTML below.   I also have a demo on
my test site.  ANy help would be appreciated.  I could add a table and
rows as that could help identify the row but it seems unnecessary.  Is
there a way to add an id to the row that was clicked with the click
event dynamically and then use the POST to remove that id? Or do I
need a counter function to add an id to each row.  How would I do that
between sesions?

DEMO:  http://janisrough.dyndns.biz/todo4.html
ALso, I don't have the data stored in a database, so you only get the
current row but I want it to work for when I get the database working.

			$(function() {
                        $(".btnDelete").click(function() {
                        // get the id here
                        var $id =this.id;

                         // POST...

                        return false;
                        });
                    });

 <section class="main">&nbsp
     <input id="toggle-all" type="checkbox">
      <label for="toggle-all">Mark all as complete</label>

<input type="checkbox" id="task" /> User Input to do item <input
type="button" value="Delete" id="btnDelete />

   </section>

Assuming you add a delete button on each row, you could assign the 
button's onclick to be something like "deleteRow(this)", and then in 
deleteRow(button) find the row that contains the specified button and 
delete that row.

Presumably your "rows" are defined by a collection of "row" elements 
inside some "container" element? Either as table rows within a table, or 
paragraphs within a div, or elements within a list etc. Presumably you 
can give the container an id, and each row is encapsulated in an element 
of the same type, so you can do something like:

function deleteRow(button){
var row,rows,rownum,elems,elnum,loop;
rows=document.getElementById(containerId).getElementsByTagName(rowTag);
rownum=rows.length;
loop=true;
while(rownum--){
row=rows.item(rownum);
elems=row.getElementsByTagName("*");
elnum=elems.length;
while(elnum--){
if(elems.item(elnum)==button){
loop=false;
break;
}
}
if(!loop)break;
}
// "row" is the dom element of the row you wish to delete
// "elems" is elements within row
}

I just noticed, you said jquery.

I have no idea whatsoever how to do this in jquery, this isn't a jquery 
forum, I think most people here avoid jquery like the plague.

You probably need to find a jquery forum to ask in.

Fortunately the code works whether jQuery is used in other
functions on the page or not. You just don't need jQuery for
this. (Some people would say you don't need jQuery for
anything. :-)

Parsing error, unmatched "(".

jquery has, like the plague had, some merit,  
it keeps the idiots of the back of serious javascript programmers,
who see the importance of writing understandable script,
by such being debuggable, 
less susceptable to external "update"-errors 
and a thing of beauty.

On the other hand, the plague didn't select on preference, only decimated,
and who are we to judge over others like the nazis did about racial purity?

Evertjan, I'm not sure I understand where you are going but I guess
you don't like Jquery either :-)  I'm hoping to get the reasons  why?

It is not about liking for me, but about writing clean, beautifull, 
working, crossbrowser safe, not updated by external forces, easily 
debuggable code.

> I'm hoping to get the reasons why?

Get as in understand or get as in receive?

Can't give you those latter ones, because it is not about not liking, but 
about advizing you not to use it.

As for the former ones, read this NG's faq and archive.

So I guess your main complaint is it is difficult to understand with
all the closing  ))}'s
I agree with that but the principle is to have anonymous functions
inside functions so that the outer function has access to the returned
value of the inner function so as to not polute the global scope and
as a way to build objects so that you can use protypical inheritance.
Now if you can do that without JQuery and you do not need Jquery for
cross browser compatibility then I guess you do not need Jquery.

Are you saying that Jquery is difficult to debug?  Firebug does not
work for Jquery?

I was reading on this link of design models why having a rich set of
controls is important.
Maybe the answer to this questions depends on who you are talking to.

Hello Denis, I appreciate your feedback.  Could you tell me why they
avoid it?
I thought it was great at solving cross browser issues.  I personally
like the controls.
For example, the calendar plug-in you can't do that in Javascript as
easily.  How about Jquery AJAX?    How does the Javascript AJAX object
compare to  the JQuery AJAX?
thanks,

Nope, I have no idea why they avoid it. I know why I avoid it.

I can usually code the js I need to do what want on a web page in much 
less space then the jquery code uses, and if I were to use jquery, I 
would still have to write my own code on top of it.

In addition, when my code doesn't work, it's pretty easy for me to fix. 
If I was using jquery and something didn't work, I'd have to trawl 
through all the jquery code as well as my own code to find the problem.

As for cross-browser compatibility, I've never found it hard to make my 
code work across a wide selection of browsers and platforms, so that I 
don't need to use jquery for cross browser compatibility.

Try asking the customers, e.g me :
a) The web page takes far too long to arrive and display fully.
b) If the web page hasn't been updated to the latest JQuery and so it
doesn't support your browser yet then some things don't work. E.g Adding
an item to the shopping basket.

Customers then zoom off to a web site that does work.

Remember to update JQuery every 6 months or so, on *every* page, and
re-test the entire, possibly enormous, web site. Yikes!

Isn't it likely that the browser will have the JQuery file cached? There 
might be an extra delay for the first request (although if you point to 
the CDN, they might already have it cached from some other site that 
also uses the CDN), but from then on it should be reasonably fast.

And if you write your own Javascript, it won't ever have compatibility 
problems with a new browser?  And in the case of old browsers, don't you 
have to duplicate all the checks that JQuery hides from you?  Or are 
they overstating the severity of the problem, to sell people on their 
code?  Since they're not making anything off it, why would they need to 
hype it with overblown claims?

Some of the arguments I've seen remind me of the arguments that were 
made many decades ago against high level languages in general: they were 
slower, they couldn't do as much as assembler.  Someone else mentioned 
that it makes debugging harder, since there's all that code that you 
didn't write yourself -- isn't that an argument against third-party 
libraries in general?  Is it really best to reinvent the wheel all the 
time?

Yes, it isn't, for there is not "*the* JQuery file".

Usually jQuery is used in a custom minimized package along with so-called 
jQuery "plugins" (e. g. [1]).  Not only do the jQuery versions in such a 
package differ from another, the sets of minimized "plugins" and versions 
thereof differ as well.

This is not a jQuery-only issue.  Script authors need to be aware that fewer 
HTTP requests for faster loading come at the price of reduced cacheability.

There is no "Javascript" [2], and if you write your scripts with 
compatibility in mind (i. e., you consider the APIs available at the time 
and use runtime feature tests to detect them before you use them), you will 
probably not have any compatibility problems with a new browser as vendors 
are very intent on keeping their new browser versions backwards-compatible.  
However, you may want to augment your tree of feature tests with another 
branch for a new API that the new browser version has to offer (giving it 
precedence if it offers a significant advantage over the other branches, 
such as standards compliance), and you may want to cut old branches.  BTDT.

The few checks for "old browsers" that jQuery hides, if any (see Resig's 
ridiculous compatibility matrix that he calls "cross-browser"), have to be 
implemented as much as backwards-compatibility is required for one's use-
case (and not as John Resig claims to know it is), and can be implemented in 
a more efficient way then.

> Or are they overstating the severity of the problem, to sell people on

Yes.

> Since they're not making anything off it,

"They" do.  A few more bad books are on the market already, and "they" do 
not hide that fact (see jquery.com at the bottom).  It is "docware" (an 
interesting term I have read on Usenet recently).

> why would they need to hype it with overblown claims?

It is a cult of ignorance.  Cult leaders want attention and dependence from 
their followers; the illusion of power and control to the disadvantage of 
many.  As with most successful cults, it is so clever a scheme that most 
people are not able or willing to recognize it – until it is too late.  
Insofar the concept does work for some time.

No, but judging from the overall code quality and reasoning for it coming 
from their authors, the majority of third-party libraries published on the 
Web was written by wannabes, jQuery included.

> Is it really best to reinvent the wheel all the time?

If it *rolls*, by comparison, and if you can know *why* that is, then you 
better do that.  Once.

We have been over this here ad nauseam.  Please research before you post.

Thank you.

Sorry to all who tried using the Matrix during the past months.  That bug 
was a side-effect of the upcoming major update (which is being developed in 
a different location) that affected all UAs.  In debug.js I had moved the 
global test() into the new jsx.debug namespace, and in object.js I removed 
_global in favor of jsx.global (which I am considering to revert since I 
have found ActionScript 3.0 to have _global), but I forgot to update the 
imports in the current (old) index file.

FIXED.  Please notify me of any further issues.  TIA.

ISTM your validator has bugs, too :)  Please double-check those warnings 
against the pertinent Specification.

The W3C Markup Validator only finds the following to be wrong:

| Line 5613, Column 34: "NOWRAP" is not a member of a group specified for
| any attribute <td class="blue" nowrap>4.0 &#8211; 4.05</td>
|
| Line 5627, Column 34: "NOWRAP" is not a member of a group specified for
| any attribute <td class="blue" nowrap>4.0 &#8211; 4.1</td>

Which is a correct assessment; the `nowrap' attribute is not allowed in HTML 
4.01 _Strict_ as it is deprecated in favor of style sheets. [1]  That will 
be fixed in the next revision of the Matrix.

Yep, you're right. I'm using HTML Tidy 0.9.5.1 when I went to the SGML 
Parser it only found the two you found.
