我想阻止退格删除项目,但保留删除按钮的功能.

我写了这个插件：

Selectize.define("stop_backspace_delete",function (options) {
  var self = this;

  this.deleteSelection = (function() {
    var original = self.deleteSelection;

    return function (e) {
      if (!e || e.keyCode !== 8) {
        return original.apply(this,arguments);
      }

      return false;
    };
  })();
});
