JavaScript 链接省略号

Question

我有以下代码:

function urlify(text) {
    var urlRegex = /(https?:\/\/[^\s]+)/g;
    return text.replace(urlRegex, function(url) {
        return '<a href="' + url + '">' + url + '</a>';
    })
    // or alternatively
    // return text.replace(urlRegex, '<a href="$1">$1</a>')
}
function dome() {
    var desc = document.getElementById('eow-description');
    desc.innerHTML = urlify(desc.innerHTML);
}

它用链接替换所有网址，但有些链接显示起来太长，这就是我想要的:

Answer 1

您可以修改urlify函数并添加slice()

function urlify(text, maxlength) {
    var urlRegex = /(https?:\/\/[^\s]+)/g;
    return text.replace(urlRegex, function(url) {
        var u = url.length > maxlength ? url.slice(0, maxlength) + '…' : url;
        return '<a href="' + url + '">' + u + '</a>';
    });
}

function dome() {
    var desc = document.getElementById('eow-description');
    desc.innerHTML = urlify(desc.innerHTML, 25);
}
