找不出原因，.replace(/&/g, '&');总是不起作用
rt
一段JS代码如下：
var temp_entity = ' ';
for(var i=0; i <picpath_true.length; i++) {
temp_entity = picpath_true[i].replace(/&/g, '& ');
alert(picpath_true[i]+ '\n '+temp_entity);
}
每次alert的结果显示，“&”都没有被替换成“&”
[解决办法]
<script>
var picpath_true=new Array( 'asd&e2 ', "& ", "sy&wq ")
var temp_entity = ' ';
for(var i=0; i <picpath_true.length; i++) {
temp_entity = picpath_true[i].replace(/&/g, '& ');
alert(picpath_true[i]+ '\n '+temp_entity);
}
</script>
其他的问题吧，
我测试没问题呀
[解决办法]
<script>
var pattern = /&/g
var str= "a&b&cad&asi ";
var str2;
function test() {
str2=str.replace(pattern, "& ");
alert(str2);
}
</script>
可以
奇怪了，你试着像我这样先定义个正则看看

没问题。还有其他信息提供吗？
