这是一个示例字符串变量：
var abc='[{"choices":"[1,2,598,214,14]","question":"There is a tom","correctAnswer":"2"},{"choices":"[1,2,598,214,14]","question":"There is a tom1","correctAnswer":"3"},{"choices":"[1,2,598,214,14]","question":"There is a tom2","correctAnswer":"4"},{"choices":"[1,2,598,214,14]","question":"There is a tom3","correctAnswer":"1"}]'
我想将"choices":"[1,2,598,214,14]"替换为此"choices":[1,2,598,214,14]并替换其他所有字符串（全局在字符串中）。
我尝试了这些：
abc.replace('"[', '[');
abc.replace(/"[/g, '['); //This also not worked though
但这仅替换第一个实例，然后停止。 我该怎么做呢？ 谢谢！
