remove escaped character
提问by geo derek
I am working with a javascript function that returns a string of XML. However, within IE I get that string of XML back with escape characters embedded in it e.g. a double quote is a \”
"
Instead of
"
Is there an easy way to remove the escaped character sequence items?
Thanks,
Derek
我正在使用一个返回 XML 字符串的 javascript 函数。然而，在 IE 中，我得到了那个嵌入了转义字符的 XML 字符串，例如双引号是一个 \" " 而不是 " 有没有一种简单的方法可以删除转义的字符序列项？
谢谢，德里克

Before trying to fix this, you should investigate which other characters are being replaced. For example, when you get a single \in other browsers do you get \\in IE?
在尝试解决此问题之前，您应该调查哪些其他字符正在被替换。例如，当您\在其他浏览器中获得单曲时，您是否\\在 IE 中获得单曲？
If the standard C escapes are added, then JSON.parsewill convert sequences like \"into ", \\into \, \ninto a line-feed, etc.
如果添加了标准的 C 转义符，那么JSON.parse会将像\"into "、\\into \、\n转换为换行符等序列。
'foo\bar\nbaz"' === JSON.parse('"foo\\bar\nbaz\""')
JSON.parseis supported natively on most recent browsers, and on IE specifically, back to IE 8. The relevant MSDN pagesays
JSON.parse在最新的浏览器上本机支持，特别是在 IE 上，回到 IE 8。相关的 MSDN 页面说

A similar question: Javascript - Replacing the escape character in a string literalexplains how to replace a escape character. Maybe you could replace the escape character with empty quotes?
一个类似的问题：Javascript - 替换字符串文字中的转义字符解释了如何替换转义字符。也许您可以用空引号替换转义字符？

Use JavaScript's replace()method.
使用 JavaScript 的replace()方法。
var string1 = "This is a string with all the \\" characters escaped";
document.write(string1); // outputs: This is a string with all the \" characters escaped
document.write("<br />");
string1 = string1.replace("\", "");
document.write(string1); // outputs: This is a string with all the " characters escaped
