转换:使用Jquery在单选按钮中选择 [英] Transforming: Select in Radio button using Jquery

问题描述

我有两个选择元素(第一个是尺寸，第二个是颜色).我在此代码中难以进行两次调整，我需要帮助以了解如何进行.

I have two select elemments (first is size, second is color). I am having trouble to make two adjusts in this code and I need help to understand how proceed.

首先: 选择选项(单选按钮)时，我使用的是已检查"类.但是问题是，当我选择第二个选项(颜色)时，我需要在第一个选项(大小)中保持选中"类.

First: I am using a class called 'checked' when I select a option (radio button). However the problem is I need keep the class 'checked' in the first option (size) when I select the second option (color).

第二: 用户必须先选择尺寸(第一个选项)，才能选择第二个选项(颜色).因此，我需要禁用颜色选项，直到用户选择尺寸为止.

Second: The user cannot select the second option (color) without select the size first (first option). So I need disable the color option until the user select a size.

$('select#iluria-product-variation1, select#iluria-product-variation2').each(function(i, select){
var $select = jQuery(select);
$select.find('option').each(function(j, option){
var $option = jQuery(option);
// Create a radio:
var $radio = jQuery('<input type="radio" />');
// Set name and value:
$radio.attr('name', $select.attr('name')).attr('value', $option.val()).attr('id', $option.text());
// Set checked if the option was selected
if ($option.attr('selected')) $radio.attr('checked', 'checked');
// Insert radio before select box:
    $select.before($radio);
    $radio.wrap('<div class="vari-option fix" />');
// Insert a label:
$radio.before(
    $("<label />").attr('for', $option.text()).text($option.text()).addClass($option.text())
);
    $(".product-variations-container").css("display", "block");
});
}); 

$(':radio').click(function(){
$(this).parent().parent().find('label').removeClass('checked');
$(this).siblings('label').addClass('checked');
$choice = $(this).attr('value');
$('select#iluria-product-variation1 option[value=' + $choice + ']').attr('selected',true).parent().trigger('change');
$('select#iluria-product-variation2 option[value=' + $choice + ']').attr('selected',true).parent().trigger('change');
});

推荐答案

您可以使用属性选择器和.on()方法来实现所需的功能，基本上，您只需要添加on()侦听器即可查看是否是否选中了第一组单选按钮.

You can use attribute selectors and the .on() method to acheive what you want to , basically you just need to add a on() listener to see if the first set of radio buttons are checked or not.

$('[name="iluria-product-variation2"]').prop('disabled', true); 

$(document).on('click' , 'input[name="iluria-product-variation1"]'  , function(){
    $('[name="iluria-product-variation2"]').prop('disabled', false) 
});

$('[name="iluria-product-variation2"]').click(function(){
    $('[name="iluria-product-variation2"]').siblings('label').removeClass('checked');
    $(this).siblings('label').addClass('checked');
    $choice = $(this).attr('value');
    $('select#iluria-product-variation1 option[value=' + $choice + ']').attr('selected',true).parent().trigger('change');
    $('select#iluria-product-variation2 option[value=' + $choice + ']').attr('selected',true).parent().trigger('change');
});

$('[name="iluria-product-variation1"]').click(function(){
    $('[name="iluria-product-variation1"]').siblings('label').removeClass('checked');
    $(this).siblings('label').addClass('checked');
    $choice = $(this).attr('value');
    $('select#iluria-product-variation1 option[value=' + $choice + ']').attr('selected',true).parent().trigger('change');
    $('select#iluria-product-variation2 option[value=' + $choice + ']').attr('selected',true).parent().trigger('change');
});

$('select#iluria-product-variation1').on('change' , function(){
    $('[name="iluria-product-variation2"]').prop('disabled', true);
});
