如何全局替换 JavaScript 字符串中的正斜杠？
回答by Seldaek
The following would do but only will replace one occurence:
以下会做，但只会替换一次出现：
"string".replace('/', 'ForwardSlash');
For a global replacement, or if you prefer regular expressions, you just have to escape the slash:
对于全局替换，或者如果您更喜欢正则表达式，您只需要转义斜杠：
"string".replace(/\//g, 'ForwardSlash');
回答by BoltClock
Use a regex literal with the gmodifier, and escape the forward slash with a backslash so it doesn't clash with the delimiters.
使用带有g修饰符的正则表达式文字，并用反斜杠转义正斜杠，这样它就不会与分隔符发生冲突。
var str = 'some // slashes', replacement = '';
var replaced = str.replace(/\//g, replacement);

Without using regex (though I would only do this if the search string is user input):
不使用正则表达式（虽然我只会在搜索字符串是用户输入的情况下这样做）：
var str = 'Hello/ world/ this has two slashes!';
alert(str.split('/').join(',')); // alerts 'Hello, world, this has two slashes!'

Is this what you want?
这是你想要的吗？
'string with / in it'.replace(/\//g, '\');
回答by Marty
This has worked for me in turning "//"into just "/".
这对我转变"//"为 just 有用"/"。
str.replace(/\/\//g, '/');

You need to wrap the forward slash to avoid cross browser issues or //commenting out.
您需要包装正斜杠以避免跨浏览器问题或//注释掉。
str = 'this/that and/if';
var newstr = str.replace(/[/]/g, 'ForwardSlash');

Hi a small correction in the above script.. above script skipping the first character when displaying the output.
嗨，上面脚本中的一个小更正……上面的脚本在显示输出时跳过了第一个字符。
function stripSlashes(x)
{
var y = "";
for(i = 0; i < x.length; i++)
{
if(x.charAt(i) == "/")
{
y += "";
}
else
{
y+= x.charAt(i);
}
}
return y;
}

This is Christopher Lincolns idea but with correct code:
这是克里斯托弗林肯的想法，但代码正确：
function replace(str,find,replace){
if (find != ""){
str = str.toString();
var aStr = str.split(find);
for(var i = 0; i < aStr.length; i++) {
if (i > 0){
str = str + replace + aStr[i];
}else{
str = aStr[i];
}
}
}
return str;
}
Example Usage:
示例用法：
var somevariable = replace('//\\/\/sdfas/\/\/\\////','\/sdf','replacethis\');
Javascript global string replacement is unecessarily complicated. This function solves that problem. There is probably a small performance impact, but I'm sure its negligable.
Javascript 全局字符串替换是不必要的复杂。这个功能解决了这个问题。性能影响可能很小，但我相信它可以忽略不计。
Heres an alternativefunction, looks much cleaner, but is on average about 25 to 20 percent slower than the above function:
这是一个替代函数，看起来更简洁，但平均比上述函数慢 25% 到 20%：
function replace(str,find,replace){
if (find !== ""){
str = str.toString().split(find).join(replace);
}
return str;
}

var str = '/questions'; // input: "/questions"
while(str.indexOf('/') != -1){
str = str.replace('/', 'http://stackoverflow.com/');
}
alert(str); // output: "http://stackoverflow.com/questions"
The proposed regex /\//gdid not work for me; the rest of the line (//g, replacement);) was commented out.
提议的正则表达式/\//g对我不起作用；该行 ( //g, replacement);)的其余部分已被注释掉。
