See the script below. Why remove() doesn’t work? I recently posted on this link: post something similar, but in the other case, the problem was why the button was inside a form, but this time there is no form on the page I already changed to input <a href="#"></a> button, but nothing works!

        function buscar(tamanho){
        var pasta = $('#pasta').val();  
        // utilizando o split para quebrar o diretorio e receber somente o nome da pasta
        var dirimg = pasta.split("/galeriaimg/");
        $.ajax({
            url: 'galeria.php?pasta=' + dirimg[1] + '&tamanho=' + tamanho,
            dataType: 'json',  

                success: function(result){ 

                   $.each(result, function(key, value){
                        var container = '<div class="col-md-4 id="col-'+key+'">';
                        container +=        '<div class="img-wrap">';
                        container +=            '<img src="/wpauditoria/images/'+tamanho+'/galeriaimg/'+dirimg[1]+'/'+value+'" class="img-return" alt="galeria" "/>';    
                        container +=            '<a href="#" class="btn btn-default btn-sm delete" onclick="excluir('+key+')"><i class="fa fa-trash"></i></a>'; 
                        container +=         '</div>';    

                        container +=         '<input type="hidden" name="imagemgaleria['+key+'][titulo]" value="/galeriaimg/'+dirimg[1]+'/'+value+'" />';    
                        container +=         '<input type="text" placeholder="Título" name="imagemgaleria['+key+'][titulo]" class="form-control inputgaleria" />';   
                        container +=         '<input type="text" placeholder="Link" name="imagemgaleria['+key+'][link]" class="form-control inputgaleria" />';   
                        container +=         '<textarea name="imagemgaleria['+key+'][descricao]" placeholder="Descricao" class="form-control inputgaleria" ></textarea>';   
                        container +=    '</div>';   

                        $('#galeriaimg').append(container);
                   });
             }
        });
    }

    function excluir(id){  
        console.log(id);  
        $("#col-"+id).remove();
}

I performed a console.log(id) to see if the id was being passed and this part works normally, the function receives the ID but does not execute the instruction $("#col-"+id).remove(); and also does not return error message.

– haykou

2017/08/25 at 23:02

– Diego Lela

2017/08/25 at 23:05
@Davidsamm , html posted, abs

– Diego Lela

2017/08/25 at 23:08
Ixi! I saw nothing calling the function excluir().

– Sam

2017/08/25 at 23:11
@Davidsamm calling in the code of the ajax, in that part container += '<a href="#" class="btn btn-default btn-sm delete" onclick="excluir('+key+')"><i class="fa fa-trash"></i></a>';

– Diego Lela

2017/08/25 at 23:12
Ah tah rs.. had not seen

– Sam

2017/08/25 at 23:13
@Diegolela and its seeking function is working?

– haykou

2017/08/25 at 23:14
@haykou is yes! displays the pictures only delete button that doesn’t work! complementing, it even works displays the id, but the part where the remove() is not clearing the div

– Diego Lela

2017/08/25 at 23:15
See if on the console a '<div class="col-md-4 id="col-'+key+'">'; is passing the value key correctly in this div.

– Sam

2017/08/25 at 23:16
@Diegolela and where is the div with id col ?

– haykou

2017/08/25 at 23:17
Let’s assume that this key be "10", see if on the console the created div appears '<div class="col-md-4 id="col-10">';. It may be going empty, there the function excluir() not finding anything.

– Sam

2017/08/25 at 23:19
Boot one console.log(key) below the line $.each(result, function(key, value){ to see if this value key is passing correctly.

A suggestion also to make your code cleaner:

And instead of you concatenating the lines repeating the variable container, just put a + at the beginning of each line, and only place ; at the end of the last.

Instead of:

var container = '<div class="col-md-4" id="col-'+key+'">';
container +=        '<div class="img-wrap">';

Use:

var container = '<div class="col-md-4" id="col-'+key+'">'
+'<div class="img-wrap">'
....
+'</div>';

thanks for the tip! these details are very valuable for those who are in the beginning! =]

Thanks for the help @haykou and @Davidsamm

The problem was in the following excerpt

<div class="col-md-4" id="col-'+key+'">';

was missing a double quotes at the end of the "col-md-4"why the instruction did not work!

From what I’ve seen your code is correct but missing the correct element in the remove, follows an example of what you are doing below:

<div id="app">
 <div class="teste"></div>
 <div id="col-1">hello</div>
</div>

js

 function buscar(){
      var teste = '<a onclick="excluir(1)">ok</a>';
   $('#app').append(teste);
 }

    function excluir(id){  
       alert('ok');
      $('#col-'+id).remove();
}

buscar(1);

By clicking on to, it performs the delete function normally.

That doesn’t answer the question. You just posted a simple example that works by disregarding his code. As he said in the question, the code is going correctly to the function excluir(). The problem must be in the code inside Ajax when it creates the element dynamically.

@Davidsamm to update the post with an Alert and console 1 minute

– Diego Lela

2017/08/25 at 23:31
@Davidsamm you found the element with id = col ?

– haykou

2017/08/25 at 23:33
Yes, inside the Ajax: var container = '<div class="col-md-4 id="col-'+key+'">';

– Sam

2017/08/25 at 23:34
@Davidsamm by print seems to have a space between the quotes and the col...

– haykou

2017/08/25 at 23:37
but my code doesn’t have that space! =/

– Diego Lela

2017/08/25 at 23:37
Thank you guys it was mistake right there! missing a double quotes"

– Diego Lela

2017/08/25 at 23:43
That’s right! Double quotes after col-Md-4.
