javascript - 寻找 。正则表达式中的字符问题

Question

我在替换正则表达式中的“joe.”等内容时遇到问题。这是代码

var objects = new Array("joe","sam");  
code = "joe.id was here so was sam.id";  
for(i = 0; i < objects.length; i++) {  
    re = new RegExp(objects[i]+"\.", "g");  
    code = code.replace(re, "stan ");  
}

我尝试过 \.、\\.、\\\.，但这些似乎都不起作用。

Answer 1

您的代码与“\\.”完美配合

var objects = new Array("joe","sam");  
code = "joe.id was here so was sam.id";  
for(i = 0; i < objects.length; i++) {  
    re = new RegExp(objects[i]+"\\.", "g");  
    code = code.replace(re, "stan ");  
}

"\\." 创建符合要求的字符串 \.。
