在浏览器标签里面添加 如下信息:

avascript: var nn = 'WRZ',
	mm = 'postmaster@wrz.link',
	uu = 'http://wrz.link';
var emname = document.getElementsByName('comname'),
	emmail = document.getElementsByName('commail'),
	emurl = document.getElementsByName('comurl'),
	wpname = document.getElementsByName('author'),
	wpmail = document.getElementsByName('email'),
	wpurl = document.getElementsByName('url'),
	zbname = document.getElementsByName('inpName'),
	zbmail = document.getElementsByName('inpEmail'),
	zburl = document.getElementsByName('inpHomePage'),
	tpmail = document.getElementsByName('mail');
if (emname.length > 0) {
	emname[0].value = nn;
	emmail[0].value = mm;
	emurl[0].value = uu;
	void(0);
} else if (wpmail.length > 0) {
	wpname[0].value = nn;
	wpmail[0].value = mm;
	wpurl[0].value = uu;
	void(0);
} else if (zbname.length > 0) {
	zbname[0].value = nn;
	zbmail[0].value = mm;
	zburl[0].value = uu;
	void(0);
} else if (tpmail.length > 0) {
	tpmail[0].value = mm;
	wpname[0].value = nn;
	wpurl[0].value = uu;
	void(0);
}

把其中信息改成自己的就可以了,之后到别人网站留言的时候 在填写个人信息时候点一下这个标签就自动填写了....
