ユーエディターのプレースホルダー設定

ueditor プレースホルダー設定:

UE.Editor.prototype.placeholder = function (justPlainText) {
    
    
   var _editor = this;
   _editor.addListener("focus", function () {
    
    
      var localHtml = _editor.getPlainTxt();
      if ($.trim(localHtml) === $.trim(justPlainText)) {
    
    
         _editor.setContent(" ");
      }
   });
   _editor.addListener("blur", function () {
    
    
      var localHtml = _editor.getContent();
      if (!localHtml) {
    
    
         _editor.setContent(justPlainText);
      }
   });
   _editor.ready(function () {
    
    
      _editor.fireEvent("blur");
   });
};

//实例化编辑器example
var editor = UE.getEditor('编辑器id');

//placeholder内容(只能是文本内容)
editor.placeholder("提示语：。。。。");
