转义正斜杠 [英] Escape forward slash

问题描述

我正在使用以下代码进行不区分大小写的搜索:

I am using this code for case insensitive searching:

Effect.find({name: new RegExp('^'+name+'$', "i")}).lean().exec(function(err, effect){
    if(err) return callback(err, null);
    callback(null, effect);
});

乍一看看起来不错.

问题:

我有一个叫test A/c的效果.

当我在数据库中搜索不区分大小写的精确匹配项时，我得到了更奇怪的结果:

When I search for an exact case insensitive match in the database, I get wiered results:

案例:1 当我搜索test A/时，我找到了一个匹配项.

Case:1 When I search for test A/, I get a match found.

案例:2 另外，对于test A/c，我也找到了匹配项.

Case:2 Also for test A/c, I get a match found.

哪种情况不适合第一种情况.我知道这是我的Regex表达问题.但是，我对Regex还是陌生的.

Which is not right for the first case. I know that is a problem with my Regex expression. But I am fairly new to Regex.

推荐答案

最后发现了错误. new RegExp()函数不需要转义backslash.我的错误是，我是从url发送此值的，因此在斜杠后将其计为新参数.

At last found the mistake. new RegExp() function does not need to escape backslash. My mistake was, I was sending this value from url and thus it was counted as new parameter after slash.
