Question

我们在angular4应用程序中使用froala编辑器，并且在尝试验证编辑器内容时遇到困难。基本上我们想要禁止只是在编辑器中键入空格，制表符或输入字符的用户。

我尝试了以下代码但没有成功：

options: Object = {
  placeholderText: '',
  height: 300,
  charCounterMax: 3000,
  htmlAllowedEmptyTags: [],
  events : {
    'froalaEditor.blur' : function(e, editor) {
      editor.html.unwrap();
      editor.html.cleanEmptyTags();
      console.log("'" + editor.html.get() + "'");
    }
  }
}

无论我做什么，我还是

'<p>&nbsp;&nbsp;</p>'

当用户输入空格键两次并验证时。是否有任何修剪功能或类似的东西？非常感谢

您可以利用innerText属性并自行修剪内容。

配置

const buttonConfig = ['bold', 'italic', 'underline', '|', 'formatOL', 'formatUL', '|', 'insertLink', '|', 'undo', 'redo'];
this.options = {
  charCounterCount: true,
  key: environment.froalaLicenseKey,
  language: 'de',
  charCounterMax: this.maxLength,
  toolbarButtons: buttonConfig,
  toolbarButtonsSM: buttonConfig,
  toolbarButtonsXS: buttonConfig,
  placeholderText: this.placeholder,
  pluginsEnabled: ['link', 'lists', 'charCounter'],
  linkAlwaysBlank: true,
  linkInsertButtons: ['linkBack'],
  linkEditButtons: ['linkOpen', 'linkEdit', 'linkRemove'],
  zIndex: 9999,
  events: {
    /*on every blur event check if the user has actually inserted content and clean if needed*/
    'froalaEditor.blur': (e: FocusEvent, editor) =>  (editor) => {
      let t = document.createElement('div');
      t.innerHTML = editor.html.get();
      let trimmedText = t.innerText.trim();
      if (!trimmedText) {
        editor.html.set('');
        editor.events.trigger('charCounter.update');
      }
    },
  },
};
