【www.bbyears.com--php入门】

部分代码删了，黄色背景的为主题关键测试,经过测试，通过找资料忙了一下午，终于将其弄成功

jsp页面

js代码

view sourceprint?

function deleSelect()

{

var delValue="";

var flag=false;

var de= document.getElementsByName("delid");

for(i=0;i

{

if(de[i].checked){

delValue+=","+de[i].value;

flag = true;

}

}

if(flag==false)

{

alert("至少你要选择一个待删除记录");

return false;

}

}
