如何将字节数组转换为字符串？
我发现这些功能正好相反:
function string2Bin(s) {
var b = new Array();
var last = s.length;
for (var i = 0; i < last; i++) {
var d = s.charCodeAt(i);
if (d < 128)
b[i] = dec2Bin(d);
else {
var c = s.charAt(i);
alert(c + ' is NOT an ASCII character');
b[i] = -1;
}
}
return b;
}
function dec2Bin(d) {
var b = '';
for (var i = 0; i < 8; i++) {
b = (d%2) + b;
d …我正在尝试在Java JEditorPane中显示内嵌图像.下面的代码使用的HTML内容可以在Firefox中正确显示图像,但不能在JEditorPane中显示.有什么想法吗？谢谢.
