我有某种动态附加到不同 div 的下拉菜单。问题是，当有人点击“关闭”时，style.display = "none" 将不起作用。我可以更改背景、不透明度、大小，但我无法隐藏它。
代码如下所示:
<style>
html, body{
height: 98%;
}
#editorViewport{
width: 90%;
height: 100%;
min-width: 400px;
min-height: 300px;
position: relative;
margin: 0 auto;
border: 1px solid red;
}
#movingElementsContainer{
display: none;
top: 0px;
left: 0px;
}
#addStartingElementBtn{
width: 60px;
height: 60px;
margin: auto;
position: absolute;
top: 0; left: 0; bottom: 0; right: 0;
}
#addStartingElementBtn:hover{
background-color: #c9eac6;
border: 1px solid grey;
cursor: pointer;
}
#elementsMenuContainer{
width: 150px;
border: 1px solid grey;
background-color: white;
min-height: 100px;
padding: 5px;
position: absolute;
z-index: 2;
display: none;
}
.elementOption{
width: 90%;
padding: 5px;
border: 1px solid grey;
}
.elementOption:hover{
border: 1px solid red;
cursor: pointer;
}
</style>
<body>
<div id="editorViewport">
<div id="addStartingElementBtn" data-Owner="starting" data-Side="starting" class="openElementsMenu">
Click!
</div>
</div>
<div id="movingElementsContainer">
<div id="elementsMenuContainer" data-Open="false" data-Owner="" data-Side="">
<div data-Kind="1" class="elementOption">
One
</div>
<div data-Kind="2" class="elementOption">
Two
</div>
<div data-Kind="3" class="elementOption">
Three
</div>
<div data-Kind="99" class="elementOption">
Close
</div>
</div>
</div>
</body>
<script type="text/javascript">
function prepareEventHandlers(){
var openElementsMenu = document.getElementsByClassName("openElementsMenu");
var event = window.attachEvent ? 'onclick' : 'click';
for(var i = 0; i < openElementsMenu.length; i++){
if(openElementsMenu[i].addEventListener){
openElementsMenu[i].addEventListener('click', elementsMenu, false);
}else{
openElementsMenu[i].attachEvent('onclick', elementsMenu);
}
}
var elementOption = document.getElementsByClassName("elementOption");
for(var i = 0; i < elementOption.length; i++){
if(elementOption[i].addEventListener){
elementOption[i].addEventListener('click', selectElementToCreate, false);
}else{
elementOption[i].attachEvent('onclick', selectElementToCreate);
}
}
}
window.onload = function(){
prepareEventHandlers();
}
var totalElements = 0;
var editorViewport = "editorViewport";
var selectedElementId = "";
var elementsMenu = function(){
var elementsMenu = document.getElementById("elementsMenuContainer")
this.appendChild(elementsMenu);
elementsMenu.style.display = "block";
elementsMenu.style.left = 61 + "px";
elementsMenu.style.top = "0px";
elementsMenu.setAttribute("data-Open", "true");
elementsMenu.setAttribute("data-Owner", this.getAttribute("data-Owner"));
elementsMenu.setAttribute("data-Side", this.getAttribute("data-Side"));
}
var selectElementToCreate = function(){
var dataKind = this.getAttribute('data-Kind');
var parentNode = document.getElementById(this.parentNode.id);
alert(dataKind)
if(dataKind == "99"){
parentNode.style.display = "none"
parentNode.setAttribute("data-Open", "false");
parentNode.setAttribute("data-Owner", "");
parentNode.setAttribute("data-Side", "");
}
}
</script>
这是一个JSFiddle
非常感谢任何建议!
最佳答案
var selectElementToCreate = function(e){
var dataKind = this.getAttribute('data-Kind');
var parentNode = document.getElementById(this.parentNode.id);
alert(dataKind)
if(dataKind == "99"){
console.log(parentNode);
parentNode.style.display = "none"
parentNode.setAttribute("data-Open", "false");
parentNode.setAttribute("data-Owner", "");
parentNode.setAttribute("data-Side", "");
alert("Wont Close :");
}
e.stopPropagation();
}
