excel导出在2003和2007版本乱码,解决办法找到
var c = "<html xmlns:o='urn:schemas-microsoft-com:office:office' xmlns:x='urn:schemas-microsoft-com:office:excel' xmlns='http://www.w3.org/TR/REC-html40'>"; c += "<head><meta charset=" + document.characterSet + " /> "
加入加粗的那一句,也就是设置编码
搞定了,修改支持中文参考
使用jquery.base64.js时发现对于中文直接抛出异常,作者压根不处理汉字的情况,因此
对其进行修正,关键函数为:
function _decode_chars(y, x){ while(y.length > 0){ var ch = y[0]; if(ch < 0x80) { y.shift(); x.push(String.fromCharCode(ch)); }else if((ch & 0x80) == 0xc0){ if(y.length < 2) break; ch = y.shift(); var ch1 = y.shift(); x.push(String.fromCharCode( ((ch & 0x1f) << 6) + (ch1 & 0x3f))); }else{ if(y.length < 3) break; ch = y.shift(); var ch1 = y.shift(); var ch2 = y.shift(); x.push(String.fromCharCode(((ch & 0x0f) << 12) + ((ch1 & 0x3f) << 6) + (ch2 & 0x3f))); } } } function _get_chars(ch, y){ if(ch < 0x80) y.push(ch); else if(ch < 0x800){ y.push(0xc0 + ((ch >> 6) & 0x1f)); y.push(0x80 + (ch & 0x3f)); }else{ y.push(0xe0 + ((ch >> 12) & 0xf)); y.push(0x80 + ((ch >> 6) & 0x3f)); y.push(0x80 + (ch & 0x3f)); } }

不支持中文
挺实用的
