There is no need for jQuery here, regular JavaScript will do:
这里不需要 jQuery，普通的 JavaScript 就可以了：
var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);
Or, the .split()and .pop()version:
var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();
Or, the regex version (several variants of this):
或者，正则表达式版本（它的几个变体）：
var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];
