尝试禁用 ckeditor 中的按钮时出错
Error when trying to disable a button in ckeditor
我正在尝试在完成某些检查后在页面加载时动态禁用按钮,但编辑器实例未定义。我加载页面的页面:
ckeditor.js
CKEDITOR.replace( 'message', {
customConfig: 'ckeditor_config'
});
check.js
在文件 check.js 中,我正在尝试动态禁用按钮 :
jQuery(document).ready(function ($) {
var pollcatid = jQuery('#poll_catid').val();
if(pollcatid !== undefined)
{
CKEDITOR.instances.message.getCommand( 'polls' ).enable();
}
else
{
CKEDITOR.instances.message.getCommand( 'polls' ).disable();
}
});
在页面加载时出现以下错误:
Uncaught TypeError: CKEDITOR.instances.message.getCommand(...) is undefined
那么为什么我的文件 check.js 有错误?
我已经想出了办法,通过这样做:
CKEDITOR.on('instanceReady', function(evt){
// Do your bindings and other actions here for example
// You can access each editor that this event has fired on from the event
var editor = evt.editor;
var pollcatid = jQuery('#poll_catid').val();
if(pollcatid !== undefined)
{
editor.getCommand( 'polls' ).enable();
}
else
{
editor.getCommand( 'polls' ).disable();
}
});
