jQuery 单选按钮、标签、更改和单击事件

发布于 2024-10-08 07:59:38 字数 4496 浏览 0 评论 0原文

我正在尝试开发一个具有多个单选按钮的表单。选择一个单选按钮将显示一组与该单选按钮相关的选项。单击标签（在本例中为图像）应该执行相同的操作。我的单选按钮部分正常工作，但标签有问题。单击标签会选择正确的单选按钮...但不会显示该按钮的内容。我知道我可以像解决单选按钮更改事件一样解决这个问题，但我不想引入超出我需要的代码。话虽这么说，我也知道必须有一种更有效的方法来处理单选按钮更改事件，因为它们都做同样的事情，只有值在变化。

这是我正在使用的内容的精简版本。我正在寻找有人帮助我正确地完成这项工作，并且同样重要的是，解决我的编码方法中的低效率问题。

I'm trying to develop a form piece that has multiple radio buttons. Selecting a radio button will display a set of options relating to that radio button. Clicking on the label (which will be an image in this case) should do the same. I have the radio button part working and am having trouble with the labels. Clicking on a label selects the correct radio button... but the content for that button is not displayed. I know I can probably work around this in the same way I am addressing the radio button change events, but I don't want to introduce more code than I need. With that being said, I also know there has to be a more efficient way to tackle the radio button change events since they all do the same thing and only the value is changing.

Here's a stripped-down version of what I am working with. I'm looking for someone to help me make this work correctly and, equally as important, address the inefficiencies in my coding approach.

      $('#contain-me .option.option-1').addClass('chosen').show();

      $('.label').click(function() {
          $(this).prev('input[type=radio]:first').attr('checked', 'checked');
      });

      $("#payment-visual-selector :radio[name='pt']").change(function(){
          var newVal = $(":radio[name='pt']:checked").val();       
          if (newVal === "1") {
              $('#contain-me .option').hide();
              $('#contain-me .option.option-1').addClass('chosen').show();
          } else if (newVal === "2") {

在收紧代码方面，这里是一个开始：

 $("#payment-visual-selector :radio").change( function(){ 
    var otherClass = '.option.option-' + $(this).val();
    $('#contain-me '+otherClass)
        .addClass('chosen').show()
        .siblings().removeClass('chosen').hide();     
 });

对于单选按钮 change 事件未由标签点击触发的问题，请尝试如下操作：

$('.label').click( function(){
  $(this).prev('input:radio')
      .attr('checked', true)
      .change(); // Manually trigger the change event
  });
});

In terms of tightening up the code, here's a start:

 $("#payment-visual-selector :radio").change( function(){ 
    var otherClass = '.option.option-' + $(this).val();
    $('#contain-me '+otherClass)
        .addClass('chosen').show()
        .siblings().removeClass('chosen').hide();     
 });

For the problem with the radio button change event not being triggered by the label click, try something like this:

$('.label').click( function(){
  $(this).prev('input:radio')
      .attr('checked', true)
      .change(); // Manually trigger the change event
  });
});
