几个有趣的Javascript Hack
1. 直接在浏览器中编辑网页内容
javascript:document.body.contentEditable='true';void(0); |
|---|
访问任意网站，在地址栏输入以上代码，会发生当前网页已经变成编模式了。将上述代码中的true改成false重新执行一遍即可恢复。
2. 舞动的图片
javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval('A()',5); void(0); |
|---|
这段js代码可能很多人已经见识过了。他的作用就是让网页上的图片飞舞起来。
3. 密码框密文变明文
javascript:(function(){var s,F,j,f,i;s="";F=document.forms;for(j=0;j<F.length;++j){f=F[j];for(i=0;i<f.length;++i){if(f[i].type.toLowerCase()=="password")s+=f[i].value+"\n";}}if(s)alert("Passwords in forms on this page:\n\n"+s);else alert("There are no passwords in forms on this page.");})(); |
|---|
访问一个带密码框的页面，然后地址栏输入以上代码，就会弹出当前密码框中的密码了，别干坏事哟~
