Here is a chat of the discussion of my problem: http://chat.stackoverflow.com/rooms/17/conversation/tabs-issue
It continues through here: http://chat.stackoverflow.com/transcript/message/4373231#4373231
I am doing the following:
$(document).on({
"click": function () {
$(this).addClass("active");
$(".TaskRow").not(this).removeClass("active").removeClass("hoverActive");
$(".TaskDetails").hide();
$(document).off("keyup", "body", keyDownFn);
keyDownFn = makeRelationships(this);
$(document).on("keyup", "body", keyDownFn);
var thisTaskDetails = ".task" + $(this).data("id") + "Details";
if (detailsArray[thisTaskDetails] !== undefined) {
detailsArray[thisTaskDetails].show();
var td = $(".taskDetails", detailsArray[thisTaskDetails]);
if ($(".hide", detailsArray[thisTaskDetails]).length) {
toggleMCE(td, $(".taskCopy", detailsArray[thisTaskDetails]))
$("#" + td.attr("id") + "_parent", detailsArray[thisTaskDetails]).show();
}
} else {
var thisID = $(this).data("id"),
displayTask = function () {
$.get(WEBROOT + INDEX + "/Task/displayTask/" + thisID, function (data) {
var domElement = $(data),
saveThis = function () {
$("form", domElement).trigger("submit");
return true;
},
taskDetails = $(".taskDetailsArea", domElement);
console.log(domElement);
detailsArray[thisTaskDetails] = domElement.appendTo(bottomLeftPane);
detailsArray[thisTaskDetails].tabs(); //ERROR HERE
console.log(domElement, detailsArray);
//*
taskDetails.tinymce({
// Location of TinyMCE script
script_url: INDEX + '/js/tiny_mce/tiny_mce.js',
// General options
theme: "advanced",
plugins: "autolink,lists,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,advlist",

console.log(ed, "setup");
ed.onChange.add(function (ed) { //blur
console.log('Editor was changed: ' + ed.id);
saveThis();
// toggleMCE(taskDetails, $(".taskCopy", domElement));
});
ed.onClick.add(function (ed, evt) { //focus
console.log('Editor was clicked: ' + ed.id, evt);
});
}
});
$("form", domElement).on("submit", function (e) {
e.preventDefault();
var posts = $(this).serialize();
$.post(WEBROOT + INDEX + "/Task/changeSomething", posts);
return false;
});
$("form", domElement).on("focus", function (e) {
e.preventDefault();
console.log("focused on body", e);
return false;
});
//*/
});
};
if (thisID !== undefined) {
displayTask();
} else {
}
}
}
}, ".TaskRow");
This whole error only happens on second load of this function. And it fails by the line detailsArray[thisTaskDetails].tabs();
Here is the stack trace:

I am using Chrome 20+
Aside:
What is returned in the $.get is from php:
<div class="TaskDetails Task task<?php echo $task['Task']['taskId']; ?>Details">
<ul>
<li><a href="#tabs-1">Details</a></li>
<li><a href="#tabs-2">Users</a></li>
<li><a href="#tabs-3">Array</a></li>
</ul>
<div id="tabs-1" style="padding: 0px; height: 100%; width: 100%;">
<form method="post" data-row="<?php echo $task['Task']['taskId']; ?>">
<?php
$details = $task['Task']['taskDetails'];
$details = nl2br($details);
$details = str_replace(array("\\r\\n", "\\r"), "\n", $details);
$details = implode("",explode("\n", $details));
$details = stripslashes($details);
?>
<textarea id="task<?php echo $task['Task']['taskId']; ?>Details" name="changedTo" class="Task task<?php echo $task['Task']['taskId']; ?> taskDetails taskDetailsArea"><?php echo $details; ?></textarea>
<div id="task<?php echo $task['Task']['taskId']; ?>Details" class="taskCopy"><?php echo $details; ?></div>
<input name="changed" value="taskDetails" type="hidden"/>
<input name="row" value="<?php echo $task['Task']['taskId']; ?>" type="hidden"/>
</form>
</div>
<div id="tabs-2" class="Task task<?php echo $task['Task']['taskId']; ?> taskUsers">
<?php echo $task['Task']['taskUsers']; ?>
</div>
<div id="tabs-3" class="Task task<?php echo $task['Task']['taskId']; ?>">
<pre><?php print_r($task);?></pre>
</div>
</div>
More info:
detailsArray is an empty object {} at the start.var thisTaskDetails = ".task" + $(this).data("id") + "Details";$(this) is some arbitrary DOM element that was clicked on.
回答1:
This may help better programmers than me zero in on a solution:
I've been noticing this error for the past week on a JS page-builder interface that I wrote myself. (No TinyMCE, but tons of jQuery plugins.) I've come to the same conclusions as the author of this ticket, i.e., jQuery is erroneously calling find() on a plain DOM element.
The interesting thing is that the problem goes away when you close the Chrome Debugger. (I'm sure we can all appreciate the irony of that one.)
I know that that doesn't bring you any closer to a solution, but at least you can rest assured that 99.9% of your users (unless they're coming from StackOverflow I suppose) will probably never see this problem.
回答2:
I believe this is a bug in Google chrome document Inspector. There is a family of related errors. It doesn't happen in other browsers. One good thing is that most users won't find this error. On the other hand, I lost 3 hrs trying to debug the problem with document inspector, when the actual solution was to close the document inspector!
