Question

我需要从名为“price”的id中的值中获取数字（条带逗号和货币符号）。我有以下内容：

<!doctype html>

        <meta charset="utf-8">

    </head>
    <body>
        <div class="container">
            <div id="homepage" class="main">
                <div id="fullpage">
                    <section class="slider section" style="background: url('http://neonrobot.com/wp-content/uploads/2014/09/unsplash-1.jpg') center center;">
                        <div class="hero">
                            <div class="header">
                                <div class="logo"><img src="assets/img/logo.png" alt="logo"></div>
                                <i id="menu-open" class="fa fa-bars fa-lg"></i>
                            </div>
                            <div class="welcome">
                                <div>
                                    <div class="hero-  headings">Hello.</div>
                                    <div class="hero-description"></div> 
                                </div>
                            </div>
                        </div>
                        <div class="clients">
                            <div class="padding25">
                                <div class="clients-intro">Our Clients. &nbsp; <i class="fa   fa-angle-right"></i><i class="fa   fa-angle-right"></i></div>
                                <div class="clients-logos">sds</div>
                            </div>
                        </div>
                    </section>

                </div>
            </div>
        </div>
        
        <script src="https://www.google-analytics.com/analytics.js" async defer></script>
    </body>
</html>

这很好用的价值就像“10.50英镑”。但如果我的值有逗号，例如“£2,050.00”，则返回“050.00”。

我如何获得数字并替换任何货币符号和逗号？

Answer 1

知道了：

function() {

var element = document.querySelector('*[id^="bew-price"]');
var price = element.innerHTML.replace(/\u00A3/g, '');
var trueprice = price.replace(/,/g , "");


return trueprice;

}

仅从值中获取数字 - 替换字符和符号
