javascript - 如何从文本 javascript 中获取 url 字符串

Question

如何从生成的文本中获取 url 字符串。 例如我生成了一个文本

text =  "This is my sample text try http:\/\/sample.com\/23411";

convertedString = "This is my sample text try http://sample.com/23411";

我想做这个

var disp = "";

disp += "This is my sample text try";
disp += "<a href = 'http://sample.com/23411'>http://sample.com/23411</a>";

结果

这是我的示例文本尝试 http://sample.com/23411

最简单的方法是使用正则表达式:

disp = text.replace(/(http:\/\/[^ ]+)/, "<a href='$1'>$1</a>");
