我正在尝试制作我的第一个Chrome扩展程序。它是一个便笺版。但是，当我尝试使用JQueryUI拖动我的版面上的第一个元素时，在Chrome中会留下水平线痕迹。
以下是屏幕截图。
以下是代码。

和 JavaScript
$(document).ready(function() {
$(function() {
$(".dragable").draggable().bind('click', function(){
$(this).focus();
});
});
$('.dragable').bind('click', function() {
$(this).attr('contenteditable', 'true');
}).blur(
function() {
$(this).attr('contenteditable', 'false');
});
})
注意：经过一些实验，我发现问题出在-webkit-transform上。如果我将其注释掉，问题就不会出现。
