JavaScript compile() Method
JavaScript RegExp Object
Definition and Usage
The compile() method is used to compile a regular expression during execution of a script.
The compile() method can also be used to change and recompile a regular expression.
Syntax
RegExpObject.compile(regexp,modifier)
| Parameter | Description |
|---|---|
| regexp | A regular expression |
| modifier | Specifies the type of matching. "g" for a global match, "i" for a case-insensitive match and "gi" for a global, case-insensitive match |
Browser Support
The compile() method is supported in all major browsers, except Opera.
Example
Example
Do a global search for "man" in a string, and replace it with "person". Then change the regular expression and replace either "man" or "woman" with "person", with the compile() method:
<script type="text/javascript">
var str="Every man in the world! Every woman on earth!";
var patt=/man/g;
var str2=str.replace(patt,"person");
document.write(str2+"<br />");
patt=/(wo)?man/g;
patt.compile(patt);
str2=str.replace(patt,"person");
document.write(str2);
</script>
var str="Every man in the world! Every woman on earth!";
var patt=/man/g;
var str2=str.replace(patt,"person");
document.write(str2+"<br />");
patt=/(wo)?man/g;
patt.compile(patt);
str2=str.replace(patt,"person");
document.write(str2);
</script>
The output of the code above will be:
Every person in the world! Every woperson on earth!
Every person in the world! Every person on earth!
Every person in the world! Every person on earth!
