You can do:
你可以做:
$("iframe[src*=sample]").attr("id");
where "sample" is the string which you are looking at.
其中“sample”是您正在查看的字符串。
Once you have the concerned iframe, you don't need the ID. You can simply reload it using the same selector.
拥有相关的iframe后,您不需要ID。您只需使用相同的选择器重新加载它。

You can give name attribute to element and then take the id of that object.
您可以为element赋予name属性,然后获取该对象的id。
var name = document.getElementsByName("box");
console.log(name[0].id);
