struts2--URL带参数的请求注意空格的影响

来源：互联网发布：pulltorefresh.js 编辑：程序博客网时间：2024/06/07 00:15

案例：

<script type="text/javascript">  function del(id){    if(confirm("确定要删除吗？")){      window.location.href = "deleteGoods.action?id ="+id;    }  }</script></head><body><div align="center"><table border="1"><tr><td>商品编号</td><td>商品名称</td><td>商品价格</td><td>商品数目</td><td>操作</td></tr><s:iterator value="list" var="good" status = "ss"><tr><td><s:property value="#good.id" /></td><td><s:property value="#good.goodsName" /></td><td><s:property value="#good.price" /></td><td><s:property value="#good.num" /></td><td>   <a href = "queryById.action?id =<s:property value="#good.id" /> ">修改</a>   <a href = "javascript:del(<s:property value="#good.id"/>)" />删除</a></td></tr></s:iterator></table>

如果把js中的一句代码改成这样：

 window.location.href = "deleteGoods.action?id = "+id;

就会报以下错误，几乎很难发现这句的bug，仔细对比，会发现请求参数id =后面多了一个空格！！
