从php中传值给JS,却传回了一个奇怪的值?解决思路
从php中传值给JS,却传回了一个奇怪的值?
我要从a.php中传一个0给b.js 可是传来的是一大串!原代码如下:
a.php文件:
echo "0";
?>
b.js文件:
function get_C()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
var c = xmlHttp.responseText;
alert(c);
}
}
对话框输出的结果却是如下一大堆字符:
0
怎么回事?能把前面的一大堆去掉吗?
------解决方案--------------------
a 输出 json
b 读取 json alert
------解决方案--------------------
前面那一大段html是哪来的?你单独执行a.php后查看源代码看看。看是不是有html代码。
