仅转义 Javascript 中的“特殊”URI 字符

Question

In JavaScript there are the two methods encodeURI() and encodeURIComponent() . The former method only replaces special characters such as spaces, umlauts, accent marks, etc. The latter also replaces the reserved symbols , /? : @ & = + $ , /? : @ & = + $ and # . But is there a method that replaces only these few reserved symbols and leaves special characters and umlauts intact?

Answer 1

If you have your own set of characters to replace, you could always do it yourself. It's just string replacement:

 const forbiddenChars = ",/?:@&=+$#".split('').reduce((acc, curr) => { acc[curr] = encodeURIComponent(curr); return acc; }, {}); const replaceIn = (input) => input.split('').map(char => forbiddenChars[char] || char).join(''); const myString = "hello / there, you"; console.log(replaceIn(myString));

Sorry about the poor performance of splitting the string and mapping over each char, you should probably not do that..
