var arr=[[[[11,22],33],44],[55,66],77];
var arr2=[];
//......
console.log(arr2)
怎么让arr2的值等于11,22,33,44,55,66,77 注意arr为层数不确定的多重数组,可能是4重,5重,6重....
------解决方案--------------------
arr.toString()不行么?
------解决方案--------------------
var arr2 = arr.toString().split(',');
------解决方案--------------------
var arr=[[[[11,22],33],44],[55,66],77];
function loop(arr)
{
var result ="";
for(var i = 0 ; i < arr.length ; i ++)
{
if(arr[i] instanceof Array) result += loop(arr[i])
else result += arr[i].toString()+"<br/>";
}
return result;
}
document.write(loop(arr))
用递归
------解决方案--------------------
var arr = [[[[11,22],33],44],[55,66],77],
arr2 = [];
function cloneArray(target, source){
for(var i = 0, len = source.length; i < len; i++){
var el = source[i];
if(Object.prototype.toString.call(el) === "[object Array]"){
cloneArray(target, el);
}else{
target.push(el);
}
}
}
cloneArray(arr2, arr);
console.log(arr2);
------解决方案--------------------
<script>
var arr=[[[[11,22],33],44],[55,66],77];
var arr2=[];
var item = arr;
var str = "";
while(item.lenght == 2) {
str = str + item[1] + ",";
item = item[0];
}
str = str + item + ",";
arr2 = str.split(",");
alert(str);
</script>
将上面SCRIPT复制,运行, 得到结果 11,22,33,44,55,66,77,
细节方面,自己处理..
------解决方案--------------------
<script type="text/javascript">
var arr=[[[[11,22],33],44],[55,66],77];
var arr2=arr.join(',').split(',');
alert(arr2);
</script>
