正则表达式匹配一个单词但不匹配另一个单词

What is wrong in this fiddle.

这个小提琴有什么不对。

 function getMatches(data,city){
             var matchArr = [];
             var pattern = new RegExp("\\b("+ city +")","gi");
        for (var i in data){        
                 var searchStr = data[i].searchstr;
                 if(pattern.test(searchStr)){
                    matchArr.push(data[i]);
                }
            }
            return matchArr;
        }

I am able to match the first address object and and the last address object but i am not able to match the second one.But the second one also has the same word. Any idea why?

我能够匹配第一个地址对象和最后一个地址对象,但我无法匹配第二个地址对象。但是第二个也有相同的单词。知道为什么吗?

Just use .indexOf()

只需使用.indexOf()

 function getMatches(data,city){
        var matchArr = [];
        for (var i in data){        
                 var searchStr = data[i].searchstr;
                 var index = searchStr.indexOf(city);
                if(index!==-1) {
                    matchArr.push(data[i]);
                }
            }
            return matchArr;
        }

var arr = getMatches(x,'Dar es');
alert("arr: " + arr.length);

OK, Regex just

好的,正则表达式

var pattern = RegExp('\\b' + city + '\\b')

var pattern = RegExp('\\ b'+ city +'\\ b')

var pattern = RegExp("\\b("+ city +")")

var pattern = RegExp(“\\ b(”+ city +“)”)
