从JavaScript或jQuery中的JSON数据中删除反斜杠

Remove Backslashes from JSON Data in JavaScript or jQuery

var str = "{"data":"{\n \"taskNames\" : [\n \"01 Jan\",\n \"02 Jan\",\n \"03 Jan\",\n \"04 Jan\",\n \"05 Jan\",\n \"06 Jan\",\n \"07 Jan\",\n \"08 Jan\",\n \"09 Jan\",\n \"10 Jan\",\n \"11 Jan\",\n \"12 Jan\",\n \"13 Jan\",\n \"14 Jan\",\n \"15 Jan\",\n \"16 Jan\",\n \"17 Jan\",\n \"18 Jan\",\n \"19 Jan\",\n \"20 Jan\",\n \"21 Jan\",\n \"22 Jan\",\n \"23 Jan\",\n \"24 Jan\",\n \"25 Jan\",\n \"26 Jan\",\n \"27 Jan\"]}

var finalData = str.replace("\\", "");

但这对我不起作用。有什么帮助？

but this does not work for me. Any help?

推荐答案

你的字符串无效，但假设它是有效的，你必须这样做：

Your string is invalid, but assuming it was valid, you'd have to do:

var finalData = str.replace(/\\/g, "");

当你想用 .replace ，第一个参数必须是正则表达式，如果你提供一个字符串，只会替换第一个匹配项，这就是你的替换不起作用的原因。

When you want to replace all the occurences with .replace, the first parameter must be a regex, if you supply a string, only the first occurrence will be replaced, that's why your replace wouldn't work.

干杯
