可能与：Uncaught TypeError: Object #<HTMLLIElement> has no method 'find'有关：

这是我的问题讨论的聊天： https

我正在执行以下操作：

$(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

                            });
                            ed.onClick.add(function (ed, evt) { //focus
                                console.log('Editor was clicked: ' + ed.id, evt);
                            });
                        }
                    });

                    $("form", domElement).on("submit", function (e) {

                        return false;

                    $("form", domElement).on("focus", function (e) {

        if (thisID !== undefined) {
            displayTask();
        } else {

        }
    }
}
}, ".TaskRow");

整个错误仅发生在此函数的第二次加载时。它失败了detailsArray[thisTaskDetails].tabs();

这是堆栈跟踪：

＃＃在旁边：

中返回的$.get内容来自 php：

<div class="TaskDetails Task task<?php echo $task['Task']['taskId']; ?>Details">
    <ul>
        <li><a href="#tabs-1">Details</a></li>

            <?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>

            <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">

    </div>
    <div id="tabs-3" class="Task task<?php echo $task['Task']['taskId']; ?>">
            <pre><?php print_r($task);?></pre>
    </div>
</div>

##More info: 开头detailsArray是一个空对象。是一些被点击的任意 DOM 元素。{}
var thisTaskDetails = ".task" + $(this).data("id") + "Details";
$(this)

这可能会帮助比我零更好的程序员解决方案：

过去一周，我在自己编写的 JS 页面构建器界面上注意到了这个错误。（没有 TinyMCE，但有大量的 jQuery 插件。）我得出了与这张票的作者相同的结论，即 jQuery 错误地在普通 DOM 元素上调用 find()。

有趣的是，当您关闭 Chrome 调试器时，问题就消失了。（我敢肯定，我们都可以体会到那个讽刺的意味。）

我知道这不会让你更接近解决方案，但至少你可以放心，你的 99.9% 的用户（除非他们来自 StackOverflow，我想）可能永远不会看到这个问题。

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!
