项目管理软件dhtmlxGantt配置教程（七）：如何自定义内联编辑器

您可以指定自定义内联编辑器。为此，您需要通过以下方式创建一个新的编辑器对象：

gantt.config.editor_types.custom_editor = {
  show: function (id, column, config, placeholder) {
    // called when input is displayed, put html markup of the editor into placeholder 
    // and initialize your editor if needed:
    var html = "
";
    placeholder.innerHTML = html;
  },
  hide: function () {
    // called when input is hidden 
    // destroy any complex editors or detach event listeners from here
  },
 
  set_value: function (value, id, column, node) {
    // set input value
  },
 
  get_value: function (id, column, node) {
    // return input value
  },
 
  is_changed: function (value, id, column, node) {
    //called before save/close. Return true if new value differs from the original one
    //returning true will trigger saving changes, returning false will skip saving 
  },
 
  is_valid: function (value, id, column, node) {
    // validate, changes will be discarded if the method returns false
    return true/false;
  },
 
  save: function (id, column, node) {
     // only for inputs with map_to:auto. complex save behavior goes here
  },
  focus: function (node) {
  }
}

为了实现可重用的编辑器，需要记住一些关键点：

• 作为一项规则，get_value不修改任务对象。该方法只返回内联编辑器的当前值。如果该值被认为有
