单击“继续”按钮Javascript时单选按钮验证

Question

我创建了一个包含 4 个单选按钮和 1 个“继续”按钮的模板，其效果如下所示

我正在尝试在单击“继续”时添加 javascript 代码：

1. 如果选择了任何单选按钮，它将弹出一个提示，您需要选择一个按钮
2. 如果选择了radio 1，它会打开页面choice1.php，如果选择radio 2，它将打开页面choice2.php，依此类推...

我正在学习一些教程并在基本示例上对其进行测试，它对我有用，但我通常会看到

<form onsubmit="return validateSubmit();" action="#"> 

和

<input type="submit" value="Submit">

当我将按钮更改为提交类型时，我失去了使用 css 添加的效果。

这是我的代码 sn-p

谁能帮我请教如何保持“继续”按钮的相同设计并添加javascript部分。

非常感谢。

如果您只想切换到其他页面而不是提交表单，您可以简单地检查单选按钮的值，然后直接重定向到特定页面，如下所示：

当您取消注释 window.location.href 行时，您将被重定向到您在控制台输出中看到的文件。

$(function(){
	$('.bttn').on('click', function(){
    	if($('input[name="selector"]').groupVal() === undefined){
        	alert('Please select an option!');
        } else {
        	console.log('choice' + $('input[name="selector"]').groupVal() + '.php');
    		//window.location.href = 'order' + $('input[name="selector"]').groupVal() + '.php';
        }
    });
});

jQuery.fn.extend({
    groupVal: function() {
        return $(this).filter(':checked').val();
    }
});
