未捕获的ReferenceError：magento站点中未定义jQuery

Question

我们正在使用以下脚本，在控制台中我们遇到了这些错误：

我们有magento site 1.9.0

我们提供了一个保存前端值的选项。

此处在前端，值未保存在数据库中。

jquery错误有问题吗？我跟着第一个回答这个链接：Uncaught ReferenceError: $ is not defined?但它确实对我有用

html代码

<span class="label qty" id="valueqty_<?php echo $assinproducts->getId(); ?>">
        <?php echo intval($assinproducts['qty']); ?>

    <input type = "text" id = "qty_<?php echo $assinproducts->getId(); ?>" onkeydown="validateNumbers(event)" 
    name="stock" value="<?php echo intval($assinproducts['qty']); ?>" style="display:none;"/>

Answer 1

您的错误消息清楚地表明您的jQuery变量未定义。只需更改此

var $wk_jq = jQuery.noConflict();

到

var $wk_jq = $.noConflict();

Answer 2

  默认情况下，

magento-1.9使用jquery。因为它使用jquery，   建议坚持使用这个默认的jquery包。

默认jquery从目录js/lib/jquery/jquery-1.10.2.min.js加载。如果进一步检查，还可以看到另一个用于避免jquery冲突的jquery文件（/js/lib/jquery/noconflict.js）。这是该js文件的内容。

// Avoid PrototypeJS conflicts, assign jQuery to $j instead of $
var $j = jQuery.noConflict();

看看评论。它说，你应该使用$j而不是$。这意味着为了避免冲突，您需要确保三件事。

1）不要使用新的jquery包，坚持使用默认包。你不打扰这一步。 Magento会为你加载它的jquery。所以请不要再添加jquery。

2）确保在默认的jquery库之后加载noconflict.js。这也是默认Magento管理。

3）现在添加放大镜库js文件（如果有的话）（可选步骤。仅当放大镜技术依赖于任何jquery包时才需要）。

4）使用您使用放大镜js库的自定义js文件。在此文件中，您应该在任何地方使用$，而不是使用$j。这样Magento就不会发生任何jquery冲突。

Answer 3

可能你没有在页面上加载jQuery。不要在页面上包含jQuery，而应该通过布局xml来完成。您甚至可以通过将其添加到app / design / frontend / package / theme / layout中的page.xml来为前端的每个页面执行此操作。一旦确定在页面上加载了jQuery，就可以选择使用noconflict，或者只使用工作jQuery替换'$'。请确保你是一致的，我在你的代码中注意到了这一点：

function updateField(product_id,assignqty)
{

//  alert("Hello! I am an alert box!!");
    var qtyId           = '#qty_'+ product_id;
    var valueId         = '#valueqty_'+ product_id;
    var updatedqty      = '#updatedqty_'+ product_id;
    var editLink        = "#edit_link_"+ product_id;
    var updateButton    = "#update_button_"+ product_id;
    var resetButton     = "#reset_button"+ product_id;
    var url             = '<?php echo Mage::getUrl('marketplace/marketplaceaccount/updateField/')?>';

    $wk_jq(qtyId).toggle();
    $wk_jq(editLink).hide();
    $wk_jq(updateButton).show();
    $wk_jq(resetButton).show();

    $qty = $wk_jq(qtyId).val();
    jQuery(valueId).html($qty);
    hideReset(product_id);

    var tmpQty = assignqty+parseInt($qty) ;

    new Ajax.Request(url, {
        method: 'post',
        parameters: {id: product_id, qty: tmpQty},
        onComplete: function (transport) {
        //  alert(tmpQty);
            jQuery(priceId).val($price);                
    jQuery(updatedqty).show().delay(2000).fadeOut();
            $updateButton.prop('disabled', false);
        }
    });
}

您正在将noconflict与原型正在使用的普通$变量混合。例如$ qty，$ price和updatebutton。如果你在这里尝试使用php变量，你必须将它们包装在一个php标签中并将它们反射出去。

Answer 4

您遇到的错误是因为您没有给出正确的jQuery库路径，这就是为什么您的页面没有获得jQuery，因此它显示错误jQuery is not defined和$ is not defined。

Answer 5

正如我所见，jQuery.js就在carrousal.js文件的下方。请将jQuery放在页面顶部，然后使用no.Conflict希望这会对你有所帮助。
