若只是想传递一个数组 作为参数操作数据库呢。 如:// 控制删除 function delItem(){ var selectFlags = document.getElementsByName("selectFlag") ; var flag = false ; var len = selectFlags.length ; //定义数组存放物料代码 var itemNos = new Array(len) ; for( var i=0; i<len; i++){ if (selectFlags[i].checked){ flag = true ; itemNos[i] = selectFlags[i].value ; } } if (!flag){ alert("请选中需要删除的物料!") ; return ; } alert(itemNos) ;
if (confirm("是否真的删除?")){ window.self.location = "DelItemServlet?itemNos="+itemNos ; } } 这样传递数组,在取参数就会考虑到逗号问题,如何传才好呢

如:// 控制删除
function delItem(){
var selectFlags = document.getElementsByName("selectFlag") ;
var flag = false ;
var len = selectFlags.length ;
//定义数组存放物料代码
var itemNos = new Array(len) ;
for( var i=0; i<len; i++){
if (selectFlags[i].checked){
flag = true ;
itemNos[i] = selectFlags[i].value ;
}
}
if (!flag){
alert("请选中需要删除的物料!") ;
return ;
}
alert(itemNos) ;
if (confirm("是否真的删除?")){
window.self.location = "DelItemServlet?itemNos="+itemNos ;
}
}
这样传递数组,在取参数就会考虑到逗号问题,如何传才好呢
