jquery 写的 select 左右 挪动的控件

参考了下multiselect的写法，想了想实现应该不难，自己写了

html：

<div class="row">  <div class="col-xs-5">    <select name="test" id="multiselect" class="form-control" size="8" multiple="multiple">      <option value="1">Item 1</option>      <option value="2">Item 5</option>      <option value="2">Item 2</option>      <option value="2">Item 4</option>      <option value="3">Item 3</option>    </select>  </div>  <div class="col-xs-2">    <button type="button" id="multiselect_rightAll" (click)="multiselect_rightAll()" class="btn btn-block"><i class="glyphicon glyphicon-forward"></i></button>    <button type="button" id="multiselect_rightSelected" (click)="multiselect_rightSelected()" class="btn btn-block"><i class="glyphicon glyphicon-chevron-right"></i></button>    <button type="button" id="multiselect_leftSelected" (click)="multiselect_leftSelected()" class="btn btn-block"><i class="glyphicon glyphicon-chevron-left"></i></button>    <button type="button" id="multiselect_leftAll" (click)="multiselect_leftAll()" class="btn btn-block"><i class="glyphicon glyphicon-backward"></i></button>  </div>  <div class="col-xs-5">    <select name="to" id="multiselect_to" class="form-control" size="8" multiple="multiple"></select>  </div></div>

jq部分

multiselect_rightAll() {    var leftAll = $("#multiselect > option");    leftAll.clone().appendTo("#multiselect_to");    leftAll.remove();  }    multiselect_leftAll() {    var rightAll = $("#multiselect_to > option");    rightAll.clone().appendTo("#multiselect");    rightAll.remove();  }    multiselect_leftSelected() {    if($("#multiselect_to option:selected").length > 0) {      var selectRight = $("#multiselect_to option:selected");      selectRight.clone().appendTo("#multiselect");      selectRight.remove();    }  }  multiselect_rightSelected() {    if($("#multiselect option:selected").length > 0) {      var selectLeft = $("#test option:selected");      selectLeft.clone().appendTo("#multiselect_to");      selectLeft.remove();      }

}

最后实现的也和multiselect一样，改按照UX改css再~
