字符串中的Javascript意外令牌錯誤

Question

我正在創建一個網頁，並希望在另一個視圖中使用一個視圖中的信息。 我正在通過python生成javascript代碼，但是我創建的字符串之一遇到了麻煩，導致了unexpected token illegal語法錯誤。

我正在像這樣在python中創建字符串：

sep = max([len(k) for k in self.keys()])
infoString = "\n".join([("(%s)%s %s" % (k," "*(sep-len(k)),v)) for k,v in self.iteritems()])
GANTTBlock.setInfo("SIMPL-Task block representation:%s" % infoString)

最終在js中看起來像這樣：

var SAT_2B = [
{label: "COMMRequest", times: [{"color":"Red", "label":"Task ID: 1", "starting_time":1420228800000, "ending_time":1420257600000, "TASKID":"1", "TASKCLASS":"COMM", "info":"SIMPL-Task block representation:(SCI_STORED_RAW)    0

    {label: "COMMPlan", times: []},
    {label: "COMMOperation", times: []},
];

在控制台上，錯誤發生在第一行（ {label: "COMMRequest", times: [{"color"... ）。 我嘗試將字符串的info部分（ "info":之后的所有內容）更改為常規的“ foo”字符串，然后運行良好。 我嘗試刪除\\n但仍然收到錯誤。 我不知道是什么引起了問題。

編輯

如果我在times:內只有一個{} ，則可以正常工作times:標簽的一部分，但在第二個{}的"TASKID"部分中斷。

控制台中不能包含這樣的換行符。 對於多行字符串，您需要每行以\\結尾：

var SAT_2B = [
{label: "COMMRequest", times: [{"color":"Red", "label":"Task ID: 1", "starting_time":1420228800000, "ending_time":1420257600000, "TASKID":"1", "TASKCLASS":"COMM", "info":"SIMPL-Task block representation:(SCI_STORED_RAW)    0/n
