正则表达式问题-删除:和之间的所有内容~

var your_string = "some text would be here and Blah St:39.74908:-104.99482:272~Turn right over here";
alert(your_string.replace(/:.+~/, "")); /* some text would be here and Blah StTurn right over here */

var str = "some text would be here and Blah St:39.74908:-104.99482:272~Turn right over here";
alert(str.replace(/:[^~]+~/g, ""));

您不需要非常复杂的正则表达式:

var str = 'Blah St:39.74908:-104.99482:272~Turn right over here';

str.replace(/:.*~/, '');

var string = 'some text would be here and Blah St:39.74908:-104.99482:272~Turn right over here'
var string2 = string.replace(/(?::-?\d+(?:\.\d+)?){3}~/g, '')

数字可以是负数,也可以是小数
