在内部文本之前插入子元素

Question

我有以下jQuery / JavaScript代码。它为现有<div>添加了几个元素。它工作得很好，只是我喜欢在第一张图片之后插入的文字。

jQuery是否提供了一种简单的语法来在内部文本之前添加子<img>元素？我知道我可以单独创建元素，但我希望保持表达式尽可能简单。

＆＃13;

＆＃13;

var div = document.getElementById("div");

var attachmentDiv = $('<div />', { 'class': 'Attachment' });
attachmentDiv.append($('<a />', { href: '#', title: 'Download Attachment', text: 'Filename.ext' })
    .append($('<img />', { src: 'https://cdn0.iconfinder.com/data/icons/typicons-2/24/spanner-128.png', 'class': 'AttachmentIcon', alt: 'File Attachment' })));
attachmentDiv.append($('<a />', { href: '#', title: 'Delete Attachment', 'data-id': '000' })
    .append($('<img />', { src: 'https://cdn0.iconfinder.com/data/icons/typicons-2/24/spanner-128.png', 'class': 'AttachmentDeleteIcon', alt: 'Delete Attachment' })));
$(div).append(attachmentDiv);

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="div"></div>

Answer 1

使用jQuery的prepend()。它的作用与append()相同，但在目标的开始标记之后插入参数。

Answer 2

var div = document.getElementById("div");

var attachmentDiv = $('<div />', { 'class': 'Attachment' });
attachmentDiv.append($('<a />', { href: '#', title: 'Download Attachment', text: 'Filename.ext' })
    .prepend($('<img />', { src: 'https://cdn0.iconfinder.com/data/icons/typicons-2/24/spanner-128.png', 'class': 'AttachmentIcon', alt: 'File Attachment' })));
attachmentDiv.append($('<a />', { href: '#', title: 'Delete Attachment', 'data-id': '000' })
    .append($('<img />', { src: 'https://cdn0.iconfinder.com/data/icons/typicons-2/24/spanner-128.png', 'class': 'AttachmentDeleteIcon', alt: 'Delete Attachment' })));
$(div).append(attachmentDiv);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="div"></div>
