Character issues in JS (conversion between binary/decimal/hexadecimal and ASCII codes)

Character issues in JS (conversion between binary/decimal/hex and ASCII codes)

var a='11160 ';

alert(parseInt(a,2)); //将111做为2进制来转换,忽略60(不符合二进制),从左至右只将符合二进制数的进行转换 
alert(parseInt(a,16)); //将所有的都进行转换

According to this method, it can actually be converted into any base

var a='1110'; 
alert(parseInt(a,10).toString(16)); //将A转换为10进制,然后再转换成16进制 同样也可以是其它进制

The following is the ASCII code:

function test(){ 
var a='ab'; 
var c=a.charCodeAt(1);//返回98 也就是b的AscII码 位置从0开始 

var char=String.fromCharCode(98);返回小写的b 
} 
//小例子 
function test(){ //输出AscII码扩展集中的字符 
var c=""; 
for(var i=1;i<65536;i++){ 
if((i%10)==0){ 
c+=i+&#39;:\t&#39;+String.fromCharCode(i)+&#39;\t&#39;+&#39;\n&#39;;}else{ 
c+=i+&#39;:\t&#39;+String.fromCharCode(i)+&#39;\t&#39;;} 
} 
document.getElementById("abc").innerText=c; 
} 
<div id=&#39;abc&#39;></div>
