本文介绍了一种在JSP中实现删除功能的方法，通过JavaScript检查复选框的选择状态来确认是否进行删除操作，并展示了如何在后端处理这些请求。

jsp里~~

<script type = "text/javascript"> function testDelete(){ flag=false; len = testForm.delid.length; for(i=0;i<len;i++){ if(testForm.delid[i].checked){ flag=true; } } if(flag == false){ alert("至少选择一个待删除记录"); return false; } testForm.action = "../test/delete.action"; testForm.submit(); } </script> <body> <s:fielderror></s:fielderror> <s:form theme = "simple" method = "post" name = "testForm"> <table > <input name=testDel" type="button" value="删除" onClick="testDelete()"> <s:iterator value="testList" status="st"> <tr> <td> <s:hidden name = "testId"/> <input name = "delid" type = "checkbox" value = "${testId}" id = "delid[#st.index]" > </td> <td><s:property value="testName"></s:property></td> </tr> </s:iterator> </table> </body> action里~~ private long[] delid = new long[]{}; public long[] getDelid() { return delid; } public void setDelid(long[] delid) { this.delid = delid; } public String deleteRecord() throws Exception {//删除记录 String idSting = ""; for(int i=0;i<this.delid.length;i++){ idSting=idSting+this.delid[i]+","; } idSting=idSting.substring(0,idSting.length()-1);//待删除记录若干id的字符串，逗号分隔 testService.delete(idSting); return SUCCESS; }
