Question

我在javascript中使用replace那个好但是当添加链接url替换我不想改变链接可以做到吗？

var someString = "The stack overflow good site http://stackoverflow.com ";
var replaced = somestring.replace(/the/g, "ing").replace(/s/g, "j");

是否可以在不更改链接的情况下进行更改？

您可以定义一个方法，将网址更改为某个内容，然后替换您的字符串，最后将网址放在原来的位置

    String.prototype.replaceStr = function (reg, strOrCallBack) {
        var str = this;
        var links = [];
        var found = true;

        while(found) {
            found = false;
            str = str.replace(/(https?:\/\/[^\s]+)/g, function(url) {
                links.push(url);
                found = true;
                return "(--" + (links.length-1) + "--)";
             });
        }

        str = str.replace(reg, strOrCallBack);

        return links.reduce(function (result, item, index) {
            return result.replace("(--" +  index + "--)", item);
        }, str);
    }

您可以在字符串上添加任意数量的网址，并且在调用方法replaceStr后，所有网址都会保持不变

var somestr = "Welcome to stack overflow --> http://stackoverflow.com";
var replaced = somestr.replaceStr(/too/g, "at").replaceStr(/o/g, "0");
// "Welc0me t0 stack 0verfl0w --> http://stackoverflow.com"

替换为javascript和链接网址
