比如：这是js一个函数：

function buyeranswer(str){

alert（"I am dengyang")

}

用下面各种写法来调用这个函数：

错误写法：

tablebuy+="<div id='page' class='clear spage'>共<s:property value='#request.pageBean.allRow' />条记录当前第"+currentPage+"/<s:property value='#request.pageBean.totalPage' />页"+" ";
if(currentPage<'${pageBean.totalPage}'){
tablebuy+="<a href='javascript:buyRecords(buyRecord?goods_id=${goods.id}&page="+next+")'>下一页</a>"+" ";
tablebuy+="<a href='javascript:buyRecords(buyRecord?goods_id=${goods.id}&page=<s:property value='#request.pageBean.totalPage'/>)'>尾页</a>";
}

错误写法：

tablebuy+="<div id='page' class='clear spage'>共<s:property value='#request.pageBean.allRow' />条记录当前第"+currentPage+"/<s:property value='#request.pageBean.totalPage' />页"+" ";
if(currentPage<'${pageBean.totalPage}'){
tablebuy+="<a href='javascript:buyRecords(‘buyRecord?goods_id=${goods.id}&page="+next+"’)'>下一页</a>"+" ";
tablebuy+="<a href='javascript:buyRecords(‘buyRecord?goods_id=${goods.id}&page=<s:property value='#request.pageBean.totalPage'/>’)'>尾页</a>";
}

tablebuy+="</div>";

错误写法：

tablebuy+="<div id='page' class='clear spage'>共<s:property value='#request.pageBean.allRow' />条记录当前第"+currentPage+"/<s:property value='#request.pageBean.totalPage' />页"+" ";
if(currentPage<'${pageBean.totalPage}'){
tablebuy+="<a href='javascript:buyRecords(+“‘”+"buyRecord?goods_id=${goods.id}&page="+next+"’)'>下一页</a>"+" ";
tablebuy+="<a href='javascript:buyRecords(+“‘”+"buyRecord?goods_id=${goods.id}&page=<s:property value='#request.pageBean.totalPage'/>’)'>尾页</a>";
}

错误写法：

tablebuy+="<div id='page' class='clear spage'>共<s:property value='#request.pageBean.allRow' />条记录当前第"+currentPage+"/<s:property value='#request.pageBean.totalPage' />页"+" ";
if(currentPage<'${pageBean.totalPage}'){
tablebuy+="<a href='javascript:buyRecords(+““”+"buyRecord?goods_id=${goods.id}&page="+next+" ”)'>下一页</a>"+" ";
tablebuy+="<a href='javascript:buyRecords(+““”+"buyRecord?goods_id=${goods.id}&page=<s:property value='#request.pageBean.totalPage'/>”)'>尾页</a>";
}

正确的写法：

tablebuy+="<div id='page' class='clear spage'>共<s:property value='#request.pageBean.allRow' />条记录当前第"+currentPage+"/<s:property value='#request.pageBean.totalPage' />页"+" ";

if(currentPage<'${pageBean.totalPage}'){
   tablebuy+="<a href='javascript:buyRecords("+"/"buyRecord?goods_id=${goods.id}&page="+next+"/")'>下一页</a>"+" ";
   tablebuy+="<a href='javascript:buyRecords("+"/"buyRecord?goods_id=${goods.id}&page=<s:property value='#request.pageBean.totalPage'/>/")'>尾页</a>";
}   tablebuy+="</div>";

归纳一下就是js中参数中如果同时带有单引号和双引号这时候需要转换（用法为 /"）:

希望对大家能用帮助！
