我的输入类似于下面的字符串:

IN|1st Cross,1st Block,IN|282,Sector 19,IN|10th Floor,Winchester House,DN|id,fgh,FG|ag

我想要的应该是这样的:

IN|1st Cross,1st Block IN|282,Sector 19 IN|10th Floor,Winchester House DN|id,fgh FG|ag

请问如何实现上述结果？

Answer 1

给你:

function separateComaForCountry(str) {
    // find a coma, that has any amount of letters after it that are not , nor | and then stop when you see either the end of the string or another | 
    var reg = /,([^|,]+(?:$|\|))/g;
    return str.replace(reg, function(match, country){
        return ' ' + country;
    });
}

然后只需根据您的用例调用该函数即可。

separateComaForCountry("IN|1st Cross,1st Block,IN|282,Sector 19,IN|10th Floor,Winchester House,DN|id,fgh,FG|ag");
// outputs IN|1st Cross,1st Block IN|282,Sector 19 IN|10th Floor,Winchester House DN|id,fgh FG|ag
