javascript - 如何获取选择器使用 find() 函数获得的 radio 输入值

标签 javascript jquery html radio-button

我尝试从子元素中获取每个子元素(项目)具有相同名称的输入字段的值。为此，我使用了each() 函数。从 radio 输入检索值时遇到问题，我从不应该的 radio 输入中获取值。代码在这里

<button id="menu-nav-action" type="submit" class="btn btn-success btn-sm">Save</button>

$(document).ready(function () {

    $("#menu-ui-sortable").collapse().sortable({
        placeholder: "ui-sortable-placeholder",
        start: function(evt, ui ){

        }
    });

    $(document).on('click', '#menu-nav-action', function (evt) {
        var menuNav = [];
        var ctn = 0;

        $("#menu-ui-sortable > div.panel.menu-item").each(function () {

            var menu_item_target = $(this).find('input[name="menu_item_target"]');
            var menu_item_target_ = menu_item_target.is(':checked') ? menu_item_target.val() : '0';

            menuNav.push({
                nav_label: $(this).find('input[name="menu_item_title"]').val(),

                nav_open_new_tab: menu_item_target_,

                nav_order: ctn});
            ctn++;
        });
        console.log(menuNav);
        alert(JSON.stringify(menuNav));
    });

});

这里是输出:

[
    {
        "nav_label":"label 1",
        "nav_title_attr":"attr 1",
        "nav_open_new_tab":"1",
        "nav_css_classes":"fa fa-glass",
        "nav_css_classes_position":"", // **this should be "left"**
        "nav_type":"page",
        "nav_link":"www.example.com/page-12",
        "nav_order":0
    },
    {
        "nav_label":"label 2",
        "nav_title_attr":"attr 2",
        "nav_open_new_tab":"0",
        "nav_css_classes":"fa fa-search",
        "nav_css_classes_position":"", // **this should be "right"**
        "nav_type":"homepage-content",
        "nav_link":"#content-4",
        "nav_order":1
    },
    {
        "nav_label":"label 3",
        "nav_title_attr":"attr 3",
        "nav_open_new_tab":"0",
        "nav_css_classes":"fa fa-files",
        "nav_css_classes_position":"left",
        "nav_type":"custom-link",
        "nav_link":"www.example.com",
        "nav_order":2
    }
]

根据 HTML，每个项目中 nav_css_classes_position 的正确值为“左”、“右”和“左”。

最佳答案

您对每个组使用相同的 radio 名称[name="menu_item_classes_position"]。为每个组使用不同的名称。

在您的示例中，有 3 个菜单项包含包裹在 Accordion 中的单选按钮。但这些单选按钮作为一个整体起作用。也就是说，当您选择第二个菜单项的单选按钮时，它将取消选择第一个菜单项的单选按钮。
