我试图获得准确的位置来删除内容。但是无法找到光标位置并且无法获取数据值。它只能在以前的位置获取值。
请帮帮我。
我试过下面的代码，
tinymce.activeEditor.selection.getRng（） - 在这里我们无法找到确切的位置。它只取得了前所未有的地位。
ed.on("drop", function($event) {
if($event.preventDefault) {
$event.preventDefault();
}
if($event.stopPropagation()) {
$event.stopPropagation();
}
if ($event.dataTransfer) {
var data = $event.dataTransfer.getData("Text");
var $data = angular.fromJson(data);
}
});
在下降中我们也无法找到确切的位置。
请给我解决方案。

这是一个棘手的问题。
我写了两个函数。一个用于获取tinymce中的绝对光标位置，另一个用于将光标设置为指定的光标位置。另外还有两个有用的函数可以在编辑器中设置插入符号，另外一个用于获取实际插入符号的块元素。我将这些功能放在我自己的自定义tinymce插件 myownplugin 中，但你可以将这些功能放在你喜欢的地方。
