Yii-视图- kindeditor编辑器的应用

比较喜欢用kindeditor,YII上的版本比较旧,所以自己重新整了个扩展

先在protected\extensions下创建KEditor文件夹用来放文件，keSource里放kindeditor的源文件，然后建三个类KEditor、KEditorManage和KEditorUpload，KEditor是扩展的主文件，KEditorManage是用来浏览服务器文件的，KEditorUpload是用来示例接收上传文件的，

echo CJSON::encode(array('error'=>0,'url'=>$originalurl));
}else{

}
配置config/main.php文件，设置上传文件存放位置




[html] view plain
copy

'params'=>array(
// this is used in contact page
'adminEmail'=>'[email protected]',
'uploadPath'=>'/upload', //添加这句，upload为存放文件文件夹的名字，自己定义，这里是放在根目录的upload文件夹

设置接收文件和浏览服务器文件的action


[html] view plain
copy

public function actions()
{
return array(
//在actions下的return array添加下面两句，没有actions的话自己添加
'upload'=>array('class'=>'application.extensions.KEditor.KEditorUpload'),
'manageJson'=>array('class'=>'application.extensions.KEditor.KEditorManage'),
);
}


在视图里面使用


[html] view plain
copy

<?php $this->widget('ext.KEditor.KEditor',array(
'model'=>$model, //传入form model
'name'=>'content', //设置name
'properties'=>array(
//设置接收文件上传的action
'uploadJson'=>'/admin/default/upload',
//设置浏览服务器文件的action，这两个就是上面配置在/admin/default的
'fileManagerJson'=>'/admin/default/manageJson',
'newlineTag'=>'br',
'allowFileManager'=>true,
//传值前加js:来标记这些是js代码
'afterCreate'=>"js:function() {
K('#ChapterForm_all_len').val(this.count());
K('#ChapterForm_word_len').val(this.count('text'));
}",
'afterChange'=>"js:function() {
K('#ChapterForm_all_len').val(this.count());
K('#ChapterForm_word_len').val(this.count('text'));
}",
),
'textareaOptions'=>array(
'style'=>'width:98%;height:400px;',
)
)); ?>

textareaOptions用来设置textarea的大小和样式，仅支持rows、cols和style
properties的各项跟js设置kindeditor的是一样的，上面的设置与下面用js设置的是一致，kindeditor原来有的项都可以设置

[html] view plain
copy

var editor1 = K.create('#editor_modelname_name', {
uploadJson : "/admin/default/upload",
fileManagerJson : "/admin/default/manageJson",
newlineTag : "br",
allowFileManager : true,
afterCreate : function() {
K('#ChapterForm_all_len').html(this.count());
K('#ChapterForm_word_len').html(this.count('text'));
},
afterChange : function() {
K('#ChapterForm_all_len').html(this.count());
K('#ChapterForm_word_len').html(this.count('text'));
}
});
