initialize tinymce with content
提问by M. Page
I have a page containing one tinymce4 editor instance. I want to initialize this editor with some content, programmatically. I know that I have to call: tinymce.get('editor').setContent('my content');
我有一个包含一个 tinymce4 编辑器实例的页面。我想以编程方式用一些内容初始化这个编辑器。我知道我必须打电话：tinymce.get('editor').setContent('my content');
However I have trouble to do this when tinymce is getting initialized. This question has already been asked: initialize tinyMCE with default contentbut the answer that was given at that time is not working, at least for tinymce4.
但是，当 tinymce 被初始化时，我很难做到这一点。已经有人问过这个问题：用默认内容初始化tinyMCE，但当时给出的答案不起作用，至少对于tinymce4。
Here is what I have tried:
这是我尝试过的：
1st attempt:
第一次尝试：
tinymce.init({
mode: "textareas",
...
setup: function (editor) {
...
editor.setContent('my content');
}
});
-> Uncaught TypeError: Cannot read property 'body' of undefined
-> 未捕获的类型错误：无法读取未定义的属性“body”
2nd attempt:
第二次尝试：
tinymce.init({
mode: "textareas",
...
};
tinymce.get('editor').setContent('my content');
-> Uncaught TypeError: Cannot read property 'setContent' of null (however if I do this when the page containing the tinymce editor has already been loaded, it works).
-> 未捕获的类型错误：无法读取 null 的属性“setContent”（但是，如果我在包含 tinymce 编辑器的页面已加载时执行此操作，则它可以工作）。
3rd attempt (SO 12083361 answer):
第三次尝试（SO 12083361 答案）：
$(document).ready(function(){
tinymce.get('editor').setContent('my content');
});
-> Uncaught TypeError: Cannot read property 'setContent' of null
-> 未捕获的类型错误：无法读取 null 的属性“setContent”
All this fails with tinymce.activeeditor.setContent('my content');as well.
所有这些都失败了tinymce.activeeditor.setContent('my content');。
Where should I place tinymce.get('editor').setContent('my content');in my code to have it working ?
我应该tinymce.get('editor').setContent('my content');在我的代码中的哪个位置放置它才能使其正常工作？

I've used the init_instance_callback, which is fired when the editor is ready to setContent.
我使用了 init_instance_callback，它在编辑器准备好 setContent 时触发。
var options = { ... };
options.init_instance_callback = function (editor) {
editor.setContent(initialContent);
};
$("some-selector").tinymce(options);
