Answer 1

尽管您不需要正则表达式完成此任务，但这里只是为了REGEX练习而提供解决方案。

var string = " http://192.168.84.98/scms?F=image&FORMAT=PNG32&TRANSPARENT=true&LAYERS=show:13&BBOXSR=aaa&IMAGESR=3857&SIZE=2528,867&BBOX=-104100.7571006687,-8544.352197105065,230333.2451006686,106152.75219710357&DPI=90";

string = string.replace(/(BBOXSR=)(\w)+(?=&)/g, "$1red");
console.info(string)
