mec*_*ism 1 html javascript jquery
我有一个HTML包含3个房间的div.我需要的是在我想要的时候更改任何房间的名称."编辑房间名称"按钮使'contenteditable ="false"'.输入所需名称后,按"验证名称"按钮,但正如您所见,警报消息显示的是先前的名称,而不是新名称.只有当我再次点击房间名称时,"nameTag"变量才会刷新并获取新值.我的问题是在输入所需名称后如何获取值？
以下是演示:
$("#editButton").click(function (){
var idTag;
var nameTag;
alert("DoubleClick the room you want to rename")
$(".roomClass").click(function (){
$(this).attr('contenteditable', 'true');
idTag = $(this).attr("data-room-id");
nameTag = $(this).text();
})
$("#confirmButton").click(function () {
PostData(idTag, nameTag);
})
})
function PostData(idTag, nameTag) {
alert(nameTag + ' with id: ' + idTag + ' was renamed!');
}<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<div class="vertical-menu">
<h3>ROOM LIST:</h3>
<button id="editButton">EDIT ROOM NAME</button><br>
<a id="content11" class="roomClass" contenteditable="false" data-room-id="0" style="cursor: pointer;">ROOM1</a><br>
<a id="content10" class="roomClass" contenteditable="false" data-room-id="9" style="cursor: pointer;">ROOM2</a><br>
<a id="content9" class="roomClass" contenteditable="false" data-room-id="8" style="cursor: pointer;">ROOM3</a><br>
<br><br>
<button id="confirmButton">VALIDATE NAME</button>
</body>
</html>只需使用.text()jquery函数即可获得价值:
var room8Value = $("[data-room-id=8]").text();
你可以查看这个jsfiddle示例
$("#editButton").click(function (){
var idTag;
var nameTag;
alert("DoubleClick the room you want to rename")
$(".roomClass").click(function (){
$(this).attr('contenteditable', 'true');
idTag = $(this).attr("data-room-id");
nameTag = $(this).text();
})
$("#confirmButton").click(function () {
PostData(idTag, nameTag);
})
});
function PostData(idTag, nameTag) {
alert(nameTag + ' with id: ' + idTag + ' was renamed! to :' + $("[data-room-id="+idTag+"]").text());
