Question

我最近使用的是jquery花式产品设计师，我遇到了以下问题。我想用产品价格进行计算，但我找不到办法。

代码是：
//价格变化时的事件处理程序

$('#clothing-designer').bind('priceChange', function(evt, price, currentPrice) {
    $('#thsirt-price').text(currentPrice);
});

，HTML是：

<div class="col-md-3">
PRICE <span class="price badge badge-inverse"><span id="thsirt-price"></span> €</span>
</div>

如何以数字形式获得价格？

额外的代码是

FancyProductDesigner.prototype.removeElement = function(element) {

    if(typeof element === 'string') {
        element = thisClass.getElementByTitle(element);
    }

    if(element.params.price != 0 && !element.params.uploadZone) {
        currentPrice -= element.params.price;
        $elem.trigger('priceChange', [element.params.price, currentPrice]);
    }

    $contextDialog.find('.fpd-content-layers .fpd-list').children('[id="'+element.id+'"]').remove();

    stage.remove(element);

    if(element.params.hasUploadZone) {

        //check if upload zone contains objects

Answer 2

如果你的HTML好像

<div class="col-md-3">
PRICE <span class="price badge badge-inverse"><span id="thsirt-price">1234</span> €</span>
</div>

然后你可以这样做

 var currentPrice = parseInt($('#thsirt-price').text().trim());

这一定有帮助。如果您将号码放在别处，请告诉我
