ArrAyBuFFEr转字符串

StringBuffer s_buffer = new String(字符串); String s_string = new StringBuffer(字符串).toString();

可以用数组的字符串拼接函数join(),例如 var arr = ["12", "34", "56"]; alert(arr.join("")); // join的参数是分隔符

function char2buf(str){ var out = new ArrayBuffer(str.length*2); var u16a= new Uint16Array(out); var strs = str.split(""); for(var i =0 ; i

function char2buf(str){ var out = new ArrayBuffer(str.length*2); var u16a= new Uint16Array(out); var strs = str.split(""); for(var i =0 ; i

function char2buf(str){var out = new ArrayBuffer(str.length*2);var u16a= new Uint16Array(out);var strs = str.split("");for(var i =0 ; i

// 字符串转为ArrayBuffer对象,参数为字符串 function str2ab(str) { var buf = new ArrayBuffer(str.length*2); // 每个字符占用2个字节 var bufView = new Uint16Array(buf); for (var i=0, strLen=str.length; i

function char2buf(str){ var out = new ArrayBuffer(str.length*2); var u16a= new Uint16Array(out); var strs = str.split(""); for(var i =0 ; i

function char2buf(str){ var out = new ArrayBuffer(str.length*2); var u16a= new Uint16Array(out); var strs = str.split(""); for(var i =0 ; i

没有直接办法,只能通过循环 String[] ary = {"abc", "123", "45"}; StringBuffer sb = new StringBuffer(); for(int i = 0; i < ary.length; i++){ sb. append(ary[i]); } String newStr = sb.toString();

字符串变为数组,最笨的方法是str.split('')分隔方法。如:var arr=str.split(',');以逗号分隔字符,结果为数组。其他方法可能就要遍历字符串的字符了。
