我在框上有一个上下文菜单,例如适用于Windows上的Chrome和IE可以正常使用的“复制/剪切/粘贴”功能,但在Safari(OSX)上则不能。出现上下文菜单,但是一旦我放开mouseclicker(无论是否在窗口上方),它就会被隐藏,并且不会捕获其<li>
上的任何单击。
我怀疑正在发生的情况是contextmenu事件的初始单击(控制单击是?)被传播到$(document),然后将其关闭。这是代码的相关部分。感谢您的帮助!
<select class="mySelectionsSelects"></select>
<select class="mySelectionsSelects"></select>
<ul id="custom-menu" style="top: 194px; left: 884px; display: none;">
<li id="customMenuCopy" data-action="copy">Copy</li>
<li id="customMenuCut" data-action="cut">Cut</li>
<li id="customMenuPaste" data-action="paste">Paste</li>
</ul>
事件处理:
jQuery(document).ready(function ($) {
$('.mySelectionsSelects').on("contextmenu", function(event) {
event.preventDefault(); event.stopPropagation();
console.log('building context menu');
$("#custom-menu").css({"top": event.pageY + "px", "left": event.pageX + "px"});
$("#custom-menu").show();
console.log('added context menu at top: ' + event.pageY + '/left: ' + event.pageX);
});
// catch click anywhere else, to close it.
$(document).on("click", function(event) {
console.log('caught click on document, hiding custom-menu');
$("#custom-menu").hide();
});
$("#custom-menu li").on("click", function(event) {
event.preventDefault(); event.stopPropagation();
console.log('caught click in li');
// This is the triggered action name
switch($(this).attr("data-action")) {
case "copy": editButton.doCopy(); break;
case "cut": editButton.doCut(); break;
case "paste": editButton.doPaste(); break;
};
// Hide it AFTER the action was triggered
$("#custom-menu").hide(100);
});
});
css:
#custom-menu {
display: none;
z-index: 1000;
position: absolute;
overflow: hidden;
border: 1px solid #CCC;
white-space: nowrap;
font-family: "Open Sans", sans-serif;
font-size: 10pt;
background: #FFF;
color: #333;
border-radius: 5px;
padding: 0;
}
#custom-menu li {
padding: 6px 9px;
cursor: pointer;
list-style-type: none;
transition: all .3s ease;
user-select: none;
}
#custom-menu li:hover {
background-color: #DEF;
}

您的怀疑是正确的!在上下文菜单关闭功能的开头添加以下行:
if (event.ctrlKey) return;
