您可以使用 substr() 和 indexOf() ：

＆＃13;

var someText = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque nec lorem eu ante ullamcorper semper. In venenatis augue sed dolor tincidunt aliquet. Quisque aliquam consectetur nunc eu congue. Ut aliquet nunc a vulputate ullamcorper. Fusce posuere nec tortor eget varius. Aenean blandit ultricies posuere. - See more at: https://mywebaddress.com#sthash.pUpdg9k4.dpuf";
someText = someText.substr(0, someText.indexOf('-')); 
console.log(someText);
