Javascript搜索并替换包含方括号的字符序列 [英] Javascript search and replace sequence of characters that contain square brackets

问题描述

我正尝试在字符串'Nationality [EN] [ESP]'中搜索'[EN]'，我想从字符串中删除它，因此我使用的是替换方法，例如下面的代码

I'm trying to search for '[EN]' in the string 'Nationality [EN] [ESP]', I want to remove this from the string so I'm using a replace method, code examaple below

var str = 'Nationality [EN] [ESP]';
var find = "[EN]";
var regex = new RegExp(find, "g");
alert(str.replace(regex, ''));

由于[EN]被标识为字符集，这将输出字符串'Nationality [] [ESP]'，但我也想删除方括号.我以为我可以使用\来逃避他们，但那没用

Since [EN] is identified as a character set this will output the string 'Nationality [] [ESP]' but I want to remove the square brackets aswell. I thought that I could escape them using \ but it didn't work

任何建议将不胜感激

推荐答案

如果您只想替换单个实例，则可以 str = str.replace("[EN]"，");否则； var find ="\\ [EN \\]"; .

If you just want to replace a single instance of it you can just str = str.replace("[EN] ", ""); otherwise; var find = "\\[EN\\]";.
