js正则如何按下面这个要求匹配？

 

 

<SCRIPT LANGUAGE="JavaScript">
	<!--
		var str = '[id:0,name:"name"][aa:"bb",id:1,name:"name"][id:2,name:"name1"]';
		//var patrn=/^\[.*id:1.*\]$/; //这个是死的，而且不正确
		document.write(patrn.exec(str));
	//-->
</SCRIPT>

 

 

有这样一段字符串，每个中括号id唯一，要求匹配指定id中括号里的内容.

 

匹配结果：[aa:"bb",id:1,name:"name"]

var str = '[id:0,name:"name"][aa:"bb",id:1,name:"name"][id:2,name:"name1"]';
var p = new RegExp("id:1");
str.replace(/\[.+?\]/g, function(m){if (p.test(m)) {console.log("bingo: " + m)}});

谢谢
