jQuery对话框未显示

Question

It seems like one of my two dialog box won't show up, although the second one does when asked to. Both are inside a $.get() success function. It is as shown:

$.getJSON('addCategory.php', {'ordre':ordre,'nom':nom}, function(data) 
                            {
                                console.log(data.result);

                                    $('div id="Dialog_Feedback2">Une catégorie porte déjà ce nom ou cet ordre!</div>').dialog(
                                    {
                                        autoOpen:false,
                                        title:'Une erreur est survenue!',
                                        width:300,
                                        height:'auto',
                                        resizable: false,
                                        show:"slide",
                                        modal:true,
                                        buttons:{
                                            "OK" : function()
                                            {
                                                $( this ).remove();
                                            }
                                        }
                                    });

                                    $('<div id="Dialog_Feedback">L\'ajout a été effectué avec succès!</div>').dialog({
                                        autoOpen:false,
                                        title:'Catégorie ajoutée!',
                                        width:400,
                                        height:'auto',
                                        resizable:false,
                                        modal:true,
                                        buttons:{
                                            "Ok": function()
                                            {
                                                $(this).remove();
                                                window.location.reload();
                                            }
                                        }
                                    }); 
                                    if(data.result =="true")
                                    {
                                        console.log("NO!");
                                        $('#Dialog_Feedback').dialog("open");
                                    }
                                    else
                                    {
                                        console.log("Yeah!");
                                        $('#Dialog_Feedback2').dialog("open");

                                    }                           
                                }

                            );
                        }

Here is what I see in the console:

false

Yeah!

But the #Dialog_Feedback2 won't show up. When it returns true , the other dialog appears correctly.

Why won't the second dialog show up?

Answer 1

It's a very simple problem, all you have to do is correctly write the div tag, you are missing the beginning carat. So the line

$('div id="Dialog_Feedback2">Une catégorie porte déjà ce nom ou cet ordre</div>').dialog(`

Should begin with

$('<d

not just

$('d

This should give you your desired operation.
