我在JavaScript&帮助下从页面抓取数据在fancybox弹出窗口上显示。
var str = "$26.61 - Framed bulletin board offers a self-stick surface for quick and easy note positioning, repositioning, and removing.";
但是当我输出它时,我得到了这个:
$26.61 , Framed bulletin board offers a self,stick surface for quick and easy note positioning, repositioning, and removing.
这是一些javascript:
var pro_desc = $('meta[name=Description]').attr("content");
var shortDesc = $.trim(pro_desc).substring(0, 225);
var count1 = shortDesc.search(/$/i);
if(count1!=-1) {
var short_desc1 = shortDesc.replace("$", "");
var short_desc2 = short_desc1.split("-");
var desc1 = short_desc2;
} else {
alert('In Else Section---'+shortDesc);
}
var product_description = desc1;
alert(product_description);
为什么我的输出有,
而不是-
?
答案 0 :(得分:0)

您在连字符上拆分:
var short_desc2 = short_desc1.split("-");
所以short_desc2
是一个包含字符串的数组,每个字符串都用连字符分隔。例如:
'foo-bar'.split('-');
// returns the array ['foo', 'bar']
现在,当你alert
一个数组(alert(product_description);
),即将它转换回一个字符串时,元素之间用逗号连接:
alert('foo-bar'.split('-'))
// alerts 'foo,bar'
// or
alert([1,2,3]);
// alerts '1,2,3'
与做的一样:
alert(arr.join(','));
