请问斜杠怎么转换成反斜杠js

'E:\wsh3038971\project\auction_app\auction_app'
怎么把每个\转换为/,\斜杠在编译的时候就没了

js没办法，识别\。它内部好像，给自动忽略了。我看了一下没有好的方法
你只能写双\

var str = 'E:\wsh3038971\project\auction_app\auction_app';
    console.log(str.replace(/\\/g, "/"));
    var str1 = 'E:\\wsh3038971\\project\\auction_app\\auction_app';
    console.log(str1.replace(/\\/g, "/"));

例子：var url = " http://localhost:64177/Home/AccordionIndex" http://localhost:64177/Home/AccordionIndex%22 ;

将斜杠转换成反斜杠：

url = url .replace("//", "\\");
url = url .replace("/", "\");
url = url .replace("/", "\");

alert(url);

将会弹出：http:\localhost:64177\Home\AccordionIndex

将反斜杠转换成斜杠：

var strurl = "http:\localhost:64177\Home\AccordionIndex";

strurl = strurl .replace("\\", "//");
strurl = strurl .replace("\", "/");
strurl = strurl .replace("\", "/");
alert(strurl );

将会弹出： http://localhost:64177/Home/AccordionIndex http://localhost:64177/Home/AccordionIndex
