我有两个divs
彼此重叠。我想要的是,当单击底部div
时,会出现一个上下文菜单,当我单击上部div
时,我想要显示不同的上下文菜单。 divs
需要保持在彼此之上。
我遇到的问题是,当我单击上部div
时,绑定事件将执行两次。我相信这是因为它们叠加在一起,并且divs
都附加了绑定事件。
有没有办法只在被点击的div
上执行一次绑定事件?基本上优先考虑最上面的(Z
轴)div
。
我有一个示例,您可以看到点击红色div
时会显示attributeMenu
上下文菜单,但是当您点击绿色div
attributeMenu and elementMenu
上下文时菜单出现。
以下是示例jsfiddle
部分代码:
addElementMenu();
addAttributeMenu();
// If the document is clicked somewhere
$(document).bind("mousedown", function (e) {
// If the clicked element is not the menu
if (!$(e.target).parents(".custom-menu").length > 0) {
// Hide it
$(".custom-menu").hide(100);
}
});
// If the menu element is clicked
$(".custom-menu li").click(function () {
// This is the triggered action name
switch ($(this).attr("data-action")) {
// A case for each action. Your actions here
case "duplicate":
duplicateItem(clicked);
break;
case "delete":
deleteItem(clicked);
break;
case "copy":
copyItem(clicked);
break;
case "cut":
cutItem(clicked);
break;
case "paste":
pasteItem();
break;
}
// Hide it AFTER the action was triggered
$(".custom-menu").hide(100);
});
function addElementMenu() {
$('.element').bind("contextmenu", function (event) {
// Avoid the real one
event.preventDefault();
//set clicked item
clicked = $(this);
parent = $(this).parent().attr('id');
console.log(clicked);
console.log(parent);
// Show contextmenu
$("#elementMenu").finish().show().css({
top: event.pageY + "px",
left: event.pageX + "px",
display: 'block'
});
});
}
function addAttributeMenu() {
$('.attribute').bind("contextmenu", function (event) {
// Avoid the real one
event.preventDefault();
//set clicked item
clicked = $(this);
parent = $(this).parent().attr('id');
console.log(clicked);
console.log(parent);
// Show contextmenu
$("#attributeMenu").finish().show().css({
top: event.pageY + "px",
left: event.pageX + "px",
display: 'block'
});
});
}
CSS:
.attribute {
width: 400px;
height: 200px;
background-color: red;
}
.element {
width: 200px;
height: 100px;
background-color: green;
}
.custom-menu {
display: none;
z-index: 1000;
position: absolute;
overflow: hidden;
border: 1px solid #CCC;
white-space: nowrap;
font-family: sans-serif;
background: #FFF;
color: #333;
border-radius: 5px;
padding: 0;
}
.custom-menu li {
padding: 8px 12px;
cursor: pointer;
list-style-type: none;
}
.custom-menu li:hover {
background-color: #DEF;
}
HTML:
<div class='attribute' id="attributeID">
