javascript - 插入 "lng": into string at specific point

Question

如何编写脚本来替换{"lat":-32.1814184, -64.4201269} 到 {"lat":-32.1814184, "lng":-64.4201269}。从 } 中查找第一次出现的 , 并替换的表达式是什么。

我的代码如下:

我正在尝试用所需的字符串替换该字符串。我写了一个函数，但是

<script>
    function getActualData(){ 
        while(true){
            var textData=document.getElementById("tss").innerHTML;
            var repeats = textData.match(/}/g).length;
            if(repeats=0) { break;}
            dIndex = textData.indexOf("}");
            if(dIndex>0){
                var s=textData.substring(dIndex-11,dIndex);
                alert(s);
                document.getElementById("tss").innerHTML=textData.replace(s,",lng:"+s);
            }
                else
                break;
        }
    }
</script>


<div id="tss">
{"ID":xxx,"Name":xxx,"emailID":xxx@aol.com,"Address":Provincial 51, Cordoba,xx ,lat":-32.1814184, -64.4201269}, {"ID":xx,"HolderName":xx,"emailID":x@aol.com,"Address":Department - Cordoba 51, xx, "lat":-32.2714158, -64.6214281}
</div>
<script>getActualData();</script>

Answer 1

这不是最令人愉快的解决方案，但这是一个Python解决方案:

import re
string = '''{"ID":xxx,"Name":xxx,"emailID":xxx@aol.com,"Address":Provincial 51, Cordoba,xx ,"lat":-32.1814184, -64.4201269},{"ID":xx,"HolderName":xx,"emailID":x@aol.com,"Address":Department - Cordoba 51, xx, "lat":-12.2714158, -64.6214281} '''
group = re.findall(r'\"lat\":[-]*[0-9]+\.[0-9]+,\ [-]*[0-9]+\.[0-9]+',string)
for coordinate_pair in group:
     string = string.replace(coordinate_pair,coordinate_pair.replace(', ',', "lng":'))

• group 是每个坐标对的列表
• 然后对其进行迭代，并替换为注入(inject)的“lng”
• 然后将固定坐标对替换为字符串
