在jquery mobile中添加动态内容时的正确格式 [英] Proper formatting when adding dynamic content in jquery mobile
问题描述
我正在尝试将一些内容动态添加到jQuery Mobile中可折叠< li> 项目的复选框列表中。我无法通过漂亮的圆角和分组项目获得正确的格式。当我在叶级别添加其他元素时，情况变得更糟。
I am trying to dynamically add some content to a list of checkboxes in an collapsible <li> item in jQuery Mobile. I cannot get the proper formatting with the nice rounded corners and the grouped items. It gets even worse when I add other elements at the leaf level.
这里是一个显示问题的示例（显然在标题中添加jquery和jquerymobile脚本和CSS）：
Here is an example that shows the problem (add jquery and jquerymobile scripts and CSS in the header obviously):
<body>
<div data-role="page" id="page">
<ul id="listList" data-role="listview">
<li id="list1" data-role="collapsible">
<h3>list 1</h3>
<div data-role="fieldcontain">
<fieldset data-role="controlgroup" id="fs1">
<input type="checkbox" id="cb1" /><label for="cb1">text</label></fieldset></div></li>
<li id="list2" data-role="collapsible">
<h3>list 2</h3>
<p>here comes another list of checkboxes...</p></li></ul>
<input type="button" onclick="addCheckbox();" value="add a checkbox to list1" /></div>
</body>
<script>
function addCheckbox() {
$("#list1 fieldset").append('<input type="checkbox" id="cb2" /><label for="cb2">More text</label>');
}
</script>
我试图添加 .page（）在调用 append（）之后但是它虽然好一点但是没有正常工作。
I tried to add .page() after the call to append()but it did not work properly though a bit better.
除了我的例子，一般的问题是在jQuery Mobile玩弄DOM结构之后如何动态地将内容附加到DOM树。我相信存在一个jquerymobilizes部分树的功能，但我找不到它。
Beyond my example, the generic question is how to dynamically append content to the DOM tree after jQuery Mobile has played around with the DOM structure. I believe there exists a function that "jquerymobilizes" part of the tree but I cannot find it.
非常感谢你的帮助！
编辑：简而言之，我正在尝试动态地将元素添加到的而不是尝试将元素添加到列表本身。刷新< li> 元素中listview listview 在这里似乎没有帮助。
In short, I am trying to dynamically add elements into one <li>element of the listview and not trying to add elements to the list itself. Refreshing the listview does not seemt o help here.
编辑2：我是我找到了 .trigger（create）函数，可以链接到 .append（）（参见 JQM常见问题解答）。使用以下脚本虽然 data-role =controlgroup没有提供带有漂亮圆角框的正确格式，但效果稍好。
EDIT 2: I am getting a bit closer as I found the .trigger("create") function that can be chained to .append() (cf JQM FAQ). With the following script it works slightly better though the data-role="controlgroup" does not provide the right formatting with nice rounded boxes.
$("#list1 fieldset").append('<input type="checkbox" id="cb2" /><label for="cb2">More text</label>').trigger("create");
如果我到达那里，我会发布完整答案。
I will post the full answer if I get there at some point.

推荐答案
我想我可以回答我自己的问题，所以这里是我得到的：
I think I could answer my own question so here is what I got:
- 在jQuery Mobile中动态添加元素使用
.trigger（create）（参见 jQuery Mobile常见问题解答） - 将它们添加到可折叠元素的可折叠部分，将其添加到
div.ui-collapsible-content或在可折叠部分事前中创建div容器，以便您直接在那里添加内容 - 以获得分组复选框的精美渲染，您应该立即添加所有复选框（当我按顺序添加它时，我无法获得圆滑的圆角
- to dynamically add elements in jQuery Mobile use
.trigger("create")(cf. jQuery Mobile FAQ) - to add them to the collapsible part of a collapsible element add it to
div.ui-collapsible-contentor create adivcontainer within the collapsible part ex ante so you add the content directly there - to get the nice rendering of grouped checkboxes, you should add all the checkboxes at once (I could not get the sleek rounded corners when I added them sequentially
S. o这是我的最终脚本，它可以满足我的需求：
So here is my final script that does what I needed:
$("#list1 div[data-role='fieldcontain']").append('<fieldset data-role="controlgroup">'
+'<input type="checkbox" id="cb1" /><label for="cb1">text</label>'
+'<input type="checkbox" id="cb2" /><label for="cb2">More text</label></fieldset>'
+'<a href="index.html" data-role="button" data-icon="delete">Delete</a>')
.trigger("create");
