Dynamically add items to Listview in jQuery Mobile
提问by Chris
I'm having a bit of trouble dynamically adding items to a listview in jQuery mobile. Basically I want whatever is input by the user in the textbox to be added to the list. I have the following code and can not figure out why the desired output is not appearing.
我在 jQuery mobile 中将项目动态添加到列表视图时遇到了一些麻烦。基本上我希望用户在文本框中输入的任何内容都添加到列表中。我有以下代码，无法弄清楚为什么没有出现所需的输出。
<script>
var listCreated = false;
function appendToList() {
if(!listCreated) {
$("#items").append("<ul id='list' data-role='listview' data-inset='true'></ul>");
listCreated = true;
$("#items").trigger("create");
}
$("#list").append("<li>");
$("#list").append(document.getElementById(item).value);
$("#list").append("</li>");
$("#list").listview("refresh");
}
</script>
<div data-role="content">
<div id="items"></div>
<input type="text" id="item" />
<input type="button" value="Add item to list" onclick="appendToList()"/>
</div>

Try creating the entire lithen appending, right now, you're appending an opening <li>to the list, then the value to the list, not the new li
尝试创建整个li然后附加，现在，您将一个开头附加<li>到列表中，然后将值附加到列表中，而不是新的li
var value = $("#item").val();
var listItem = "<li>" + value + "</li>";
$("#list").append(listItem);
