Question

我使用+/-按钮添加到我的product-list.tpl输入，直到我使用blocklayered模块中的任何过滤器，然后+/-按钮停止工作。

我的输入如下：

<input type='button' value='-' class='qtymin' field='qty' />
<input type="text" class='qtynum' name="qty" id="quantity_to_cart_{$product.id_product|intval}" value="1"/>
<input type='button' value='+' class='qtypl' field='qty' />

Js代码是：

jQuery(document).ready(function(){
        // This button will increment the value
        $('.qtyplus').click(function(e){
            // Stop acting like a button
            e.preventDefault();
            // Get the field name
            fieldName = $(this).attr('field');
            // Get its current value
            var currentVal = parseInt($('input[name='+fieldName+']').val());
            // If is not undefined
            if (!isNaN(currentVal)) {
                // Increment
                $('input[name='+fieldName+']').val(currentVal + 1);
            } else {
                // Otherwise put a 0 there
                $('input[name='+fieldName+']').val(0);
            }
        });
        // This button will decrement the value till 0
        $(".qtyminus").click(function(e) {
            // Stop acting like a button
            e.preventDefault();
            // Get the field name
            fieldName = $(this).attr('field');
            // Get its current value
            var currentVal = parseInt($('input[name='+fieldName+']').val());
            // If it isn't undefined or its greater than 0
            if (!isNaN(currentVal) && currentVal > 0) {
                // Decrement one
                $('input[name='+fieldName+']').val(currentVal - 1);
            } else {
                // Otherwise put a 0 there
                $('input[name='+fieldName+']').val(0);
            }
        });
    });

关于为什么这不起作用的任何想法？

尝试将事件附加到文档：

    jQuery(document).ready(function(){
        // This button will increment the value
        $(document).on('click', '.qtyplus', function(e){
            // Stop acting like a button
            e.preventDefault();
            // Get the field name
            fieldName = $(this).attr('field');
            // Get its current value
            var currentVal = parseInt($('input[name='+fieldName+']').val());
            // If is not undefined
            if (!isNaN(currentVal)) {
                // Increment
                $('input[name='+fieldName+']').val(currentVal + 1);
            } else {
                // Otherwise put a 0 there
                $('input[name='+fieldName+']').val(0);
            }
        });
        // This button will decrement the value till 0
        $(document).on('click', '.qtyminus', function(e) {
            // Stop acting like a button
            e.preventDefault();
            // Get the field name
            fieldName = $(this).attr('field');
            // Get its current value
            var currentVal = parseInt($('input[name='+fieldName+']').val());
            // If it isn't undefined or its greater than 0
            if (!isNaN(currentVal) && currentVal > 0) {
                // Decrement one
                $('input[name='+fieldName+']').val(currentVal - 1);
            } else {
                // Otherwise put a 0 there
                $('input[name='+fieldName+']').val(0);
            }
        });
    });
