Magento2

Question

我使用的代码是这样的：

jQuery(document).ready(function($){
    if(window.location.href =='https://mysite/csproduct/vproducts/new/set/4/type/simple/'){
    console.log('ready');
    $("[name='product[vendor_price]']").keyup(function() {
    $("[name='product[price]']").val($(this).val()).change();
    });
    }
});

如果我将代码粘贴到控制台，它就可以工作。即使没有粘贴我得到的代码 console.log - 准备就绪。除此之外，控制台没有错误。

这里使用的

HTML是这样的：

<div class="admin__field _required" data-bind="css: $data.additionalClasses, attr: {'data-index': index}, visible: visible" data-index="vendor_price">       
<label class="admin__field-label" data-bind="attr: {for: uid}, visible: $data.labelVisible" for="CTK9J41">

<span data-bind="attr: {'data-config-scope': $data.scopeLabel}, text: label" data-config-scope="[STORE VIEW]">Vendor Price</span>
</label>   

<div class="admin__field-control" data-bind="css: {'_with-tooltip': $data.tooltip, '_with-reset': $data.showFallbackReset &amp;&amp; $data.isDifferedFromDefault}">
<input class="admin__control-text" type="text" data-bind="
        event: {change: userChanges},
        value: value,
        hasFocus: focused,
        valueUpdate: valueUpdate,
        attr: {
            name: inputName,
            placeholder: placeholder,
            'aria-describedby': noticeId,
            id: uid,
            disabled: disabled
    }" name="product[vendor_price]" aria-describedby="notice-CTK9J41" id="CTK9J41">
    </div>
</div>


<div class="admin__field admin__field-small _required" data-bind="css: $data.additionalClasses, attr: {'data-index': index}, visible: visible" data-index="price">

<span data-bind="attr: {'data-config-scope': $data.scopeLabel}, text: label" data-config-scope="[STORE VIEW]">Price</span>
    </label>

<div class="admin__field-control" data-bind="css: {'_with-tooltip': $data.tooltip, '_with-reset': $data.showFallbackReset &amp;&amp; $data.isDifferedFromDefault}">

<div class="admin__control-addon">                

<input class="admin__control-text" type="text" data-bind="
        event: {change: userChanges},
        value: value,
        hasFocus: focused,
        valueUpdate: valueUpdate,
        attr: {
            name: inputName,
            placeholder: placeholder,
            'aria-describedby': noticeId,
            id: uid,
            disabled: disabled
    }" name="product[price]" aria-describedby="notice-JHLHU2O" id="JHLHU2O">   

<label class="admin__addon-prefix" data-bind="attr: {for: uid}" for="JHLHU2O">

<span data-bind="text: addbefore">₹</span>
</label>
    </div>
</div>

Answer 1

Magento 2 使用 Knockout.js 框架动态构建其前端的某些部分。该建筑物也会在 jQuery ready 事件触发后发生。所以可能是name='product[vendor_price]'的元素在你找的时候DOM里面还没有

使事件侦听器工作的一种方法是使用 event delegation with on:

$(document).on("keyup", "[name='product[vendor_price]']", function() {
    $("[name='product[price]']").val($(this).val()).change();
});

注意：与您的问题无关，但请尝试使用 "input" 事件而不是 "keyup"：这也将通过上下文菜单（清除、剪切、粘贴），通过其他输入设备，或者当一个键被按住并重复时。

Magento2 - 添加一个小的 jquery ，它在升级前工作正常
