chrome,firefox下面運(yùn)行都很正常，唯獨(dú)在safari下會(huì)爆SyntaxError: DOM Exception 12錯(cuò)誤：

這是個(gè)什么error？沒(méi)見(jiàn)過(guò)baidu一下有了:
DOMException是W3C DOM核心對(duì)象。
DOMException接口表示一個(gè)處理的錯(cuò)誤，當(dāng)一個(gè)操作不可能執(zhí)行的時(shí)候，會(huì)拋出一個(gè)異常。
例如試圖創(chuàng)建一個(gè)無(wú)效的DOM, 或通過(guò)一個(gè)不存在的節(jié)點(diǎn)作為參數(shù)節(jié)點(diǎn)操作方法。
SYNTAX_ERR code 12 --> 無(wú)效或非法的字符串被指定。

先從error stack中找到出錯(cuò)的地方,在angular-file-upload-all.js中的以下位置:
1 var key, i;
2 function patchXHR(fnName, newFn) {
3 window.XMLHttpRequest.prototype[fnName] = newFn(window.XMLHttpRequest.prototype[fnName]);
4 }
5
6
if (window.XMLHttpRequest && !window.XMLHttpRequest.__isFileAPIShim) {
7 patchXHR('setRequestHeader', function (orig) {
8
return function (header, value) {
9
if (header === '__setXHR_') {
10 var val = value(
this);
11
// fix for angular < 1.2.0
12
if (val
instanceof Function) {
13 val(
this);
14 }
15 }
else {
16 orig.apply(
this, arguments);
17 }
18 }
19 });
20 }
出錯(cuò)的位置在第16行，把header打出來(lái)看了一下,Authorization的值是這樣的'Token '的，后面多了一個(gè)空格，果斷刪除掉空格再試，不爆錯(cuò)了，原來(lái)是空格惹的禍，為什么會(huì)出錯(cuò)呢，想去看看這個(gè)orig的內(nèi)容是什么，可碰到[
native code],這個(gè)估計(jì)是c＋＋的code,這個(gè)要如何看得到內(nèi)容呢，問(wèn)題是解決了，但還未探清問(wèn)題的源頭，又是c代碼，請(qǐng)高人指點(diǎn)。
