当我的表单提交时，我使用它来将 tinymce 的内容复制到它已替换的文本区域以进行验证。
var content = tinyMCE.activeEditor.getContent();
$('#article').val(content);
问题是，编辑器的内容在启动时如下（尽管我在编辑器中什么都看不到）：
<span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,serif; font-style: italic; font-weight: 100;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,sans-serif; font-style: italic; font-weight: 100;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,serif; font-style: italic; font-weight: 400;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,sans-serif; font-style: italic; font-weight: 400;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,serif; font-style: italic; font-weight: 600;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,sans-se...ont-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,serif; font-style: normal; font-weight: 400;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,sans-serif; font-style: normal; font-weight: 400;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,serif; font-style: normal; font-weight: 600;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,sans-serif; font-style: normal; font-weight: 600;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,serif; font-style: normal; font-weight: bold;">BESbswy</span><span style="position: absolute; top: -999px; left: -999px; font-size: 300px; width: auto; height: auto; line-height: normal; margin: 0; padding: 0; font-variant: normal; font-family: proxima-nova,sans-serif; font-style: normal; font-weight: bold;">BESbswy</span>
有谁知道为什么会发生这种情况以及如何防止它？
