每个 Editor.md 的 ID 元素下都有一个保存 Markdown 源码的 Textarea，你也可以通过设置开启另一个保存 HTML 源码的 Textarea，可以按需要获取相应的值，如下：
|
|
|
|
|
|
|
|
|
|
```html
|
|
|
|
|
<div class="editormd" id="$id">
|
|
|
|
|
<textarea class="editormd-markdown-textarea" name="$id-markdown-doc"></textarea>
|
|
|
|
|
|
|
|
|
|
<!-- html textarea 需要开启配置项 saveHTMLToTextarea == true -->
|
|
|
|
|
<textarea class="editormd-html-textarea" name="$id-html-code"></textarea>
|
|
|
|
|
</div>
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
#### Example
|
|
|
|
|
|
|
|
|
|
```javascript
|
|
|
|
|
var testEditor = editormd("test-editormd", {
|
|
|
|
|
width : "90%",
|
|
|
|
|
height : 640,
|
|
|
|
|
path : "../lib/",
|
|
|
|
|
saveHTMLToTextarea : true
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
testEditor.getMarkdown(); // 获取 Markdown 源码
|
|
|
|
|
testEditor.getHTML(); // 获取 Textarea 保存的 HTML 源码
|
|
|
|
|
testEditor.getPreviewedHTML(); // 获取预览窗口里的 HTML，在开启 watch 且没有开启 saveHTMLToTextarea 时使用
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
#### Backend get form value

|
|
|
|
|
|
|
|

假设编辑器 ID 为 `test-editormd`，以 PHP 为例：
|
|
|
|
|
|
|
|
|
|
```php
|
|
|
|
|
<?php
|
|
|
|
|
header("Content-Type:text/html; charset=utf-8");
|
|
|
|
|
|
|
|
|
|
if (isset($_POST['submit'])) {
|
|
|
|
|
echo "<pre>";
|
|
|
|
|
echo htmlspecialchars($_POST["test-editormd-markdown-doc"]);
|
|
|
|
|
echo "<br/><br/>";
|
|
|
|
|
echo htmlspecialchars($_POST["test-editormd-html-code"]);
|
|
|
|
|
echo "</pre>";
|
|
|
|
|
}
|
|
|
|
|
?>
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
</textarea>
