一个脚本的小问题
var type_dim_id= "-1 ";
var type_id= "-1 ";
var dimObj=document.all.type_dim_id;
for(var i=0;i <dimObj.length;i++){
if(dimObj[i].checked){
var inputs =document.getElementsByTagName( "input ");
var obj;
var radioName;
for(var j=0;j <inputs.length;j++)
{
if(inputs[j].type== "radio "){
obj = inputs[j];
radioName = obj.name;
if(obj.checked){
if(radioName.substring(4,radioName.length)==type_dim_id){
type_id=obj.value;
alert(type_id);
type_dim_id=dimObj[i].value;
alert(type_dim_id);
}
}
}
}
}
}
alert( "type_id= "+type_id);
alert( "type_dim_id= "+type_dim_id);
我在循环里alert可以有数据 可一到循环外面就是-1，这两个变量都是全局的郁闷
------解决方案--------------------
我这么写怎么没问题啊,是别的地方的错儿吧.
------解决方案--------------------
if(radioName.substring(4,radioName.length)==type_dim_id)
这个条件看着有问题.你radioName的名字里会有-1吗?
