如何通过比较 Jquery 或 Javascript 中的两个字符串来删除字符串中重复的部分
原标题:How to remove the duplicated part of string by comparing two string in Jquery or Javascript
$str1= <option value="AAA">AAA</option><option value="BBB">BBB</option><option value="CCC">CCC</option> ;

$str2= <option value="CCC">CCC</option><option value="DDD">DDD</option> ;

如果 $str2 的一部分与 $str1 的一部分重复,那么删除$2的重复部分。

预期成果:

$expectedStr =  <option value="DDD">DDD</option> ;

有人能帮我吗?

最佳回答
var str1= <option value="AAA">AAA</option><option value="BBB">BBB</option><option value="CCC">CCC</option> ,
    str2= <option value="CCC">CCC</option><option value="DDD">DDD</option> ,

    result = str2.replace(/<option .+?</option>/g, function(m) {
        return (str1.indexOf(m) > -1)? "" : m;
    });

console.log(result); //returns <option value="DDD">DDD</option>

(这里我假定您要检查 </option> )
