javascript - 尝试在 document.ready 中使用 jQuery 在 Bigcommerce Classic Next 主题中触发对产品选项的点击

好的，所以我有一个产品着陆页，没有加载特定产品选项的选项，这在将电子商务网站与特定尺寸及其各自的价格、重量等的产品提要链接时会产生一个大问题。所以我有这个某个产品的着陆页，我需要根据 URI 参数在 document.ready 上加载特定选项。我想传递“大小”并根据查询字符串触发对 Twin、Full、Queen 或 King 的点击。这是我正在查看的示例:mattress product page .不过，我离解析和处理参数还差得很远。

我的问题是我一下子跳进了 HTML、CSS、Javascript 和 jQuery 中，但我并不是 100% 了解自己在做什么。现在我只是想确定我应该在哪个对象上触发点击。我找到的所有教程都有一个名称供引用，如本例所示 jQuery not triggering on radio button change .我在 chrome 的开发者控制台中尝试了以下尝试的一系列组合，但它似乎不包括 header 中引用的 jQuery 脚本。

如果有人能解释我应该使用的对象是哪个类或选择器，它在脚本中的操作方式以及它在 DOM 中的显示方式，我将不胜感激。另外，如果有人有任何引用书可以推荐，请这样做。

应该是这样的吗

$(".ProductOptionList option:first").click();

或

$(".VariationSelect:eq(*index of array of selections I want to click*)").something? attr()? var()? html()?

这里是(希望)javascript的相关部分

来自 product.js:

$(document).ready(function() {

...

// disable all but the first variation box
$(".VariationSelect:gt(0)").attr('disabled', 'disabled');

var prodVarSelectionMap = {}
$(".VariationSelect").change(function() {
    // cache a map of currently selected values.
    var mapIndex = 0;
    $('.VariationSelect').each(function() {
        prodVarSelectionMap[mapIndex] = this.value;
        mapIndex++;
    });

    // get the index of this select
    var index = $('.VariationSelect').index($(this));

    // deselected an option, disable all select's greater than this
    if (this.selectedIndex == 0) {
        $('.VariationSelect:gt(' + index + ')').attr('disabled', 'disabled')
        updateSelectedVariation($('body'));
        return;
    }
    else {
        // disable selects greater than the next
        $('.VariationSelect:gt(' + (index + 1) + ')').attr('disabled', 'disabled')
    }

    //serialize the options of the variation selects
    var optionIds = '';
    $('.VariationSelect:lt(' + (index + 1) + ')').each(function() {
        if (optionIds != '') {
            optionIds += ',';
        }

        optionIds += $(this).val();
    });
    // request values for this option
    $.getJSON(
        '/remote.php?w=GetVariationOptions&productId=' + productId + '&options=' + optionIds,

            // were options returned?
            if (data.hasOptions) {
                // load options into the next select, disable and focus it
                $('.VariationSelect:eq(' + (index + 1) + ') option:gt(0)').remove();
                $('.VariationSelect:eq(' + (index + 1) + ')').append(data.options).attr('disabled', false).focus();

                // auto select previously selected option, and cascade down, if possible
                var preVal = prodVarSelectionMap[(index + 1)];
                if (preVal != '') {
                    var preOption = $('.VariationSelect:eq(' + (index + 1) + ') option[value=' +preVal+']');
                    if (preOption) {
                        preOption.attr('selected', true);
                        $('.VariationSelect:eq(' + (index + 1) + ')').trigger('change');
                    }
                }
            }
            else if (data.comboFound) { // was a combination found instead?
                // display price, image etc
                updateSelectedVariation($('body'), data, data.combinationid);
            }
        }
    );
});

//radio button variations
$('.ProductOptionList input[type=radio]').click(function() {
    //current selected option id
    var optionId = $(this).val();
    // request values for this option
    $.getJSON(
        '/remote.php?w=GetVariationOptions&productId=' + productId + '&options=' + optionId,
        function(data) {
            if (!data) {
                return;
            }

            if (data.comboFound) { // was a combination found instead?

最佳答案

如果您正在使用 radio 并尝试取消选择所有 radio 然后选择一个特定的 radio ，您需要两件事:名称和唯一标识符。使用名称取消选择该组中的所有，并使用 ID 选择您需要的那个。如果你没有身份证，你总是可以使用值(value)。或者，如果您只想选择第一个可用的元素，请使用名称获取单选/检查组，并使用 .first() 过滤器获取第一个匹配的元素。

如何使用名称或值的属性选择器:http://api.jquery.com/attribute-equals-selector/

如何通过 ID 获取:http://api.jquery.com/id-selector/

触发“点击”事件也会触发任何绑定(bind)到点击或更改元素的事件。如果您需要，请像您尝试的那样触发点击。但是，如果您只需要切换检查状态，则可以使用此方法:How to uncheck a radio button?

作为您评论后的编辑:很高兴看到您为此使用一些核心 JavaScript。当我处理表单时，我喜欢结合使用 jQuery。像这样的东西:

$('[name="attribute[251]"]').each(function() {
    this.checked = false;
});

或

$('#b0204680fe57cec48dab9edc28a34a7d')[0].checked = true;

每个人对此都有自己的偏好。这只是一个示例方法。
