了解。


非常感谢，

In PHP there is a function called str_replace
(http://php.net/str_replace). Basically you can freed in two strings
and a "subject" string. Then it goes through the subject string
searching for occurences of the "search" string and replaces them with
the "replace" string. Is there something simular in JavaScript, or can
someone give me a solution. I am an experienced PHP user and XHTML
writer, and I have learnt Javascript to a reasonable level so you don''t
need to explain it too simply but simple enough for a programmer to
understand.

Many Thanks,
Michael Mulqueen.

尝试替换 String [1]对象的方法。


[1]< url：http：//developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference：Global_Objects：Strin g> ;

Try the "replace" method of the String[1] object.

在JavaScript中没有完全相同的srt_replace，但是如果它可以使用RegExp工具与
完全相同需要。


如果你只需要一个快速的'''''''''''的解决方案那么：

....

var s1 =" abababababababab";

var s2 = s1.replace（/ a / g，''c''）;

alert（s2）; // cbcbcb ...

....


所以：subject.replace（/ searchString / g，" replaceString"）;


/ searchString / g是带有/ g标志的正则表达式，用于替换所有

出现，而不仅仅是第一个。

There is not exact equivalent of srt_replace in JavaScript, but one can
make an exact equivalent of it using RegExp tools if it''s needed.

If you just need a quick''n''durty solution then:
....
var s1 = "abababababababab";
var s2 = s1.replace(/a/g,''c'');
alert(s2); // cbcbcb...
....

So: subject.replace(/searchString/g, "replaceString");

/searchString/g is a regular expression with /g flag to replace all
occurences, not just the first one.

谢谢，这是一个很好的建议，但它太脏了，我必须去现金洗手了:(。无论如何有帮助，但我也想知道，如果

我启动了一个blah.html的弹出窗口，从弹出窗口我怎么可以用这个来编辑主文档中的textarea？

Thankyou, that was great advice, but it is so dirty that I have to go
and wash my hands now :(. Anyway that helps but I also wondered, say if
I launched a pop up window of blah.html, from the pop up window how
could I edit a textarea in the main document with this?
