JS数组变成PHP中相等的数组请高手指点？

Question

$city2 = array( array("山西省", "0"), array("河北省", "0"), array("太原市", "山西省").....)

Answer 1

谢谢你的帮助，我把下面的代码复制出来。我想把下面JS的数组从PHP的数据库中提出来传给JS，在这个关节上我做不到，麻烦你帮我看看。先谢谢了~<script language="JavaScript" type="text/javascript">
//ChangeSelect(上一级的值,下一级Select控件的ID值,下一级Select控件要选中的值(即value而非text),数据源数组名,默认显示字符(如:请选择...如果不写的话会用默认值填充))，第一级的上级值为0
function ChangeSelect(ParentValue, NextId, NextSelectedValue, ArrObj,DefaultStr)
{
StrObj = eval(document.getElementById(NextId));
StrObj.length = 0;
//判断它是二级数据源，还是三级
if (ArrObj.length > 0)
{
if (ArrObj[0].length == 2)
{ArrNum = 0;}
else
{ArrNum = 2;}
}
//显示所有列表
for (i = 0; i < ArrObj.length; i++)
{
if (i == 0)
{
if (DefaultStr == undefined ) DefaultStr="==请选择==";
StrObj.options[StrObj.length] = new Option(DefaultStr, "");
}
if (ArrObj[i][1] == ParentValue)
{
StrObj.options[StrObj.length] = new Option(ArrObj[i][0],ArrObj[i][ArrNum]);
}
}
//选中列表内某一项
for (i = 0; i < StrObj.length; i++)
{
if (StrObj.options[i].value == NextSelectedValue)
{
StrObj.options[i].selected = true;
}
}
//激发下一级的onchange事件以实现多级级联
StrObj.onchange();
}
//公司二维数组数据源

Answer 2

楼主是想做select联动吧,你这种做法就是将数据库所用的资源一次都提取出来.
其实有两种方式实现这种效果.
1 在php中循环,然后在php中生成javascript的变量.
  比如说:
   
    echo "<script language='javascript'>";
    echo "var City3 = [];
    for($i=0;$i<10;$i++)
    {
       //在这里给数组传值
    }
    echo "</script>";
  
2 另一种情况是在php中构造数组字符串,然后传给javascript,在javascript再用split函数,将其变为数组.
这种方式最常用,因为程序看上去比较好维护,也很直接.

把js的变成php的：
<script>
City2 = [ 
["CategoryName","ParentCategoryName"], 
["山西省","0"], 
["河北省","0"], 
["太原市","山西省"], 
["运城市","山西省"], 
["石家庄","河北省"], 
["廊房","河北省"] 
]
document.cookie="City2="+City2
</script>
<?php
$City2=$_COOKIE["City2"];
echo $City2;
?>php的转为js的：
<?php
$City2=...
?>
<script>
City2=<?echo $City2>
</script>
