jquery的eval的使用

jquery的eval的使用

eval（) 函数可计算某个字符串，并执行其中的的 JavaScript 代码。

<script type="text/javascript">
  var str="1+2+3";
  alert(eval（str));
</script>

<button type="button" id="gfyButton" class="btn btn-info btn-sm" action="querySelect(this,event)">
                                    选择
              </button>

执行css方法

    };
eval（_this.listOption.loadSuccess());
