Safari Javascript中的错误？ [英] Bug in Safari Javascript?
问题描述
运行下面的代码时，所有浏览器都会显示Hello World。除了Safari之外无法匹配
正则表达式。另请参见 http://www.testabc.nl/safari/test.html
当我改变[^ A] *？进入。*？或者在字符串末尾添加一个空格Safari正常工作
再次。
我想这是Safari Javascript中的一个错误，还是？
< html>
< head>
< script language = JavaScript type = text / javascript>
var reg_date = /（Hello [^ A] *？）\ * * $ /;
var str =''开始：Hello world' ';
功能显示（）
{
if（str.search（reg_date）！= - 1）警报（RegExp。$ 1）;
其他警报（不匹配......）;
}
< / script>
< / head>
< body>
< h3> Javascript代码：< / h3>
< div> var reg_date = /（Hello [^ A] *？）\ * * $ /;< / div> ;
< div> var str =''开始：Hello world'';< / div>
< div> if（str.search（reg_date） ！= -1）警报（RegExp。$ 1）;< / div>
< divelse alert（" No match .. 。"）;< / div>
< p>< button onclick =" show（）;"> start< / button>< / p> ;
< / body>
< / html>
/;
var str =''开始：Hello world'';
函数show（）
{
if（str.search（reg_date）！= -1）alert（RegExp。
1）;
else alert（" ;不匹配...）;
}
< / script>
< / head>
< body>
< h3> Javascript代码：< / h3>
< div> var reg_date = /（Hello [^ A] *？）\ * *
/;< / div>
< div> var str =''开始：Hello world'';< / div>
< div> if（str.search（reg_date）！= -1）alert（RegExp。
When running the code below, all browsers are showing "Hello World" except Safari which cannot match
the regular expression. See also http://www.testabc.nl/safari/test.html
When I change [^A]*? into .*? or add a space at the end of the string Safari is working alright
again.
I guess this is a bug in Safari Javascript, or?
<html>
<head>
<script language=JavaScript type=text/javascript>
var reg_date = /(Hello[^A]*?)\s*$/;
var str = ''Start: Hello world'';
function show()
{
if(str.search(reg_date) != -1) alert(RegExp.$1);
else alert ("No match...");
}
</script>
</head>
<body>
<h3>Javascript code:</h3>
