javascript - 无法将所有 ^ 符号替换为 25%5E

Question

这个问题已经有答案了:

How do I replace all occurrences of a string in JavaScript? (78 个回答)

已关闭 去年。

我已经替换了react中的问题。我希望^变为25%5E，但我只能替换字符串中的^之一，无法替换所有^ 25%5E。下面是我的示例代码:

var urlStr = "http://localhost:3005/branch-management/edit-branch/?companyName=ABC%20SDN%20BHD%20!!!!%40%40%40%40%23%24%^%26*()&branchName=ABC%20!%40%23%24%^%26*()_";
var newUrlStr = urlStr.replace("^", "25%5E");

console.log(newUrlStr);

错误结果:

如何解决这个问题？

您应该使用replaceAll用于替换所有匹配的字符串

var urlStr = "http://localhost:3005/branch-management/edit-branch/?companyName=ABC%20SDN%20BHD%20!!!!%40%40%40%40%23%24%^%26*()&branchName=ABC%20!%40%23%24%^%26*()_";
var newUrlStr = urlStr.replaceAll("^", "25%5E");

console.log(newUrlStr);

您还可以使用正则表达式与 /g ( a global flag ) 来实现类似的行为

    var urlStr = "http://localhost:3005/branch-management/edit-branch/?companyName=ABC%20SDN%20BHD%20!!!!%40%40%40%40%23%24%^%26*()&branchName=ABC%20!%40%23%24%^%26*()_";
var newUrlStr = urlStr.replace(/\^/g, "25%5E");

console.log(newUrlStr);
