如何使用 jQuery 根据单选按钮选择显示/隐藏 div？

发布于 2024-08-31 15:06:01 字数 1160 浏览 6 评论 0原文

我有一些单选按钮，我希望根据选择的单选按钮显示不同的隐藏 div。 HTML 如下所示：

<form name="form1" id="my_form" method="post" action="">
    <div><label><input type="radio" name="group1" value="opt1">opt1</label></div>  
    <div><label><input type="radio" name="group1" value="opt2">opt2</label></div>  
    <div><label><input type="radio" name="group1" value="opt3">opt3</label></div>  
    <input type="submit" value="Submit">
</form>

....

<style type="text/css">
    .desc { display: none; }
</style>

....

<div id="opt1" class="desc">lorem ipsum dolor</div>
<div id="opt2" class="desc">consectetur adipisicing</div>
<div id="opt3" class="desc">sed do eiusmod tempor</div>

这是我的 jQuery：

$(document).ready(function(){ 
    $("input[name$='group2']").click(function() {
        var test = $(this).val();
        $("#"+test).show();
    }); 
});

我这样做的原因是因为我的单选按钮和 div 是动态生成的（单选按钮的值将始终有一个相应的 div）。上面的代码部分工作 - 当选中正确的按钮时，div 将显示，但我需要添加一些代码，以便在取消选中按钮后使 div 再次隐藏。谢谢！

I have some radio buttons and I'd like to have different hidden divs show up based on which radio button is selected. Here's what the HTML looks like:

<form name="form1" id="my_form" method="post" action="">
    <div><label><input type="radio" name="group1" value="opt1">opt1</label></div>  
    <div><label><input type="radio" name="group1" value="opt2">opt2</label></div>  
    <div><label><input type="radio" name="group1" value="opt3">opt3</label></div>  
    <input type="submit" value="Submit">
</form>

....

<style type="text/css">
    .desc { display: none; }
</style>

....

<div id="opt1" class="desc">lorem ipsum dolor</div>
<div id="opt2" class="desc">consectetur adipisicing</div>
<div id="opt3" class="desc">sed do eiusmod tempor</div>

And here's my jQuery:

$(document).ready(function(){ 
    $("input[name$='group2']").click(function() {
        var test = $(this).val();
        $("#"+test).show();
    }); 
});

The reason I'm doing it that way is because my radio buttons and divs are being generated dynamically (the value of the radio button will always have a corresponding div). The code above works partially - the divs will show when the correct button is checked, but I need to add in some code to make the divs hide again once the button is unchecked. Thanks!

更新 2015/06

随着 jQuery 自问题发布以来不断发展，现在推荐的方法是使用 $.on

$(document).ready(function() {
    $("input[name=group2]").on( "change", function() {

         var test = $(this).val();
         $(".desc").hide();
         $("#"+test).show();
    } );
});

或外部 $.ready()

$(document).on( "change", "input[name=group2]", function() { ... } );

原始答案

您应该使用.change()事件处理程序：

$(document).ready(function(){ 
    $("input[name=group2]").change(function() {
        var test = $(this).val();
        $(".desc").hide();
        $("#"+test).show();
    }); 
});

应该可以工作

Update 2015/06

As jQuery has evolved since the question was posted, the recommended approach now is using $.on

$(document).ready(function() {
    $("input[name=group2]").on( "change", function() {

         var test = $(this).val();
         $(".desc").hide();
         $("#"+test).show();
    } );
});

or outside $.ready()

$(document).on( "change", "input[name=group2]", function() { ... } );

Original answer

You should use .change() event handler:

$(document).ready(function(){ 
    $("input[name=group2]").change(function() {
        var test = $(this).val();
        $(".desc").hide();
        $("#"+test).show();
    }); 
});

should work

在显示之前隐藏它们：

$(document).ready(function(){ 
    $("input[name$='group2']").click(function() {
        var test = $(this).val();
        $("div.desc").hide();
        $("#"+test).show();
    }); 
});

Just hide them before showing them:

$(document).ready(function(){ 
    $("input[name$='group2']").click(function() {
        var test = $(this).val();
        $("div.desc").hide();
        $("#"+test).show();
    }); 
});

我不咬妳我踢妳 2024-09-07 15:06:01
$(document).ready(function(){ 
    $("input[name=group1]").change(function() {
        var test = $(this).val();
        $(".desc").hide();
        $("#"+test).show();
    }); 
});

在此示例中，input[name=group1] 是正确的。不过，感谢您的代码！

$(document).ready(function(){ 
    $("input[name=group1]").change(function() {
        var test = $(this).val();
        $(".desc").hide();
        $("#"+test).show();
    }); 
});

It's correct input[name=group1] in this example. However, thanks for the code!

一个有趣的解决方案是使其成为声明式的：您只需为每个应该显示的 div 提供一个属性 automaticallyVisibleIfIdChecked 以及它所依赖的复选框或单选按钮的 id。也就是说，您的表单如下所示：

<form name="form1" id="my_form" method="post" action="">
    <div><label><input type="radio" name="group1" id="rdio1" value="opt1">opt1</label></div>  
    <div><label><input type="radio" name="group1" id="rdio2" value="opt2">opt2</label></div>  
</form>
....
<div id="opt1" automaticallyVisibleIfIdChecked="rdio1">lorem ipsum dolor</div>
<div id="opt2" automaticallyVisibleIfIdChecked="rdio2">consectetur adipisicing</div>

并且具有一些独立于页面的 JavaScript，可以很好地使用函数式编程：

function executeAutomaticVisibility(name) {
    $("[name="+name+"]:checked").each(function() {
        $("[automaticallyVisibleIfIdChecked=" + this.id+"]").show();
    });
    $("[name="+name+"]:not(:checked)").each(function() {
        $("[automaticallyVisibleIfIdChecked=" + this.id+"]").hide();
    });
}

$(document).ready( function() {
    triggers = $("[automaticallyVisibleIfIdChecked]")
        .map(function(){ return $("#" + $(this).attr("automaticallyVisibleIfIdChecked")).get() })
    $.unique(triggers);
    triggers.each( function() {
        executeAutomaticVisibility(this.name);
        $(this).change( function(){ executeAutomaticVisibility(this.name); } );
    });
});

类似地，您可以使用属性 automaticallyEnabledIfChecked 自动启用/禁用表单字段。

我认为这种方法很好，因为它避免了为您的页面创建特定的 JavaScript - 您只需插入一些说明应该做什么的属性。

An interesting solution is to make this declarative: you just give every div that should be shown an attribute automaticallyVisibleIfIdChecked with the id of the checkbox or radio button on which it depends. That is, your form looks like this:

<form name="form1" id="my_form" method="post" action="">
    <div><label><input type="radio" name="group1" id="rdio1" value="opt1">opt1</label></div>  
    <div><label><input type="radio" name="group1" id="rdio2" value="opt2">opt2</label></div>  
</form>
....
<div id="opt1" automaticallyVisibleIfIdChecked="rdio1">lorem ipsum dolor</div>
<div id="opt2" automaticallyVisibleIfIdChecked="rdio2">consectetur adipisicing</div>

and have some page independent JavaScript that nicely uses functional programming:

function executeAutomaticVisibility(name) {
    $("[name="+name+"]:checked").each(function() {
        $("[automaticallyVisibleIfIdChecked=" + this.id+"]").show();
    });
    $("[name="+name+"]:not(:checked)").each(function() {
        $("[automaticallyVisibleIfIdChecked=" + this.id+"]").hide();
    });
}

$(document).ready( function() {
    triggers = $("[automaticallyVisibleIfIdChecked]")
        .map(function(){ return $("#" + $(this).attr("automaticallyVisibleIfIdChecked")).get() })
    $.unique(triggers);
    triggers.each( function() {
        executeAutomaticVisibility(this.name);
        $(this).change( function(){ executeAutomaticVisibility(this.name); } );
    });
});

Similarily you could automatically enable / disable form fields with an attribute automaticallyEnabledIfChecked.

I think this method is nice since it avoids having to create specific JavaScript for your page - you just insert some attributes that say what should be done.

相同的简单 jquery 源 -

$("input:radio[name='group1']").click(function() {      
    $('.desc').hide();
    $('#' + $("input:radio[name='group1']:checked").val()).show();
});

为了使其更合适，只需将选中添加到第一个选项 -

<div><label><input type="radio" name="group1" value="opt1" checked>opt1</label></div>

从样式中删除 .desc 类并修改 div 之类 -

<div id="opt1" class="desc">lorem ipsum dolor</div>
<div id="opt2" class="desc" style="display: none;">consectetur adipisicing</div>
<div id="opt3" class="desc" style="display: none;">sed do eiusmod tempor</div>

无论如何，它看起来确实不错。

The simple jquery source for the same -

$("input:radio[name='group1']").click(function() {      
    $('.desc').hide();
    $('#' + $("input:radio[name='group1']:checked").val()).show();
});

In order to make it little more appropriate just add checked to first option --

<div><label><input type="radio" name="group1" value="opt1" checked>opt1</label></div>

remove .desc class from styling and modify divs like --

<div id="opt1" class="desc">lorem ipsum dolor</div>
<div id="opt2" class="desc" style="display: none;">consectetur adipisicing</div>
<div id="opt3" class="desc" style="display: none;">sed do eiusmod tempor</div>

it will really look good any-ways.

您可以使用 jQuery 的 show() 和 hide() 方法。如下所示：

JQuery：

  $(document).ready(function(){
    $('input[type="radio"]').click(function(){
      var val = $(this).attr("value");
      var target = $("." + val);
      $(".msg").not(target).hide();
      $(target).show();
    });
  });

HTML：

<input type="radio" name="color" value="yellow"> Yellow
<input type="radio" name="color" value="red"> Red
<input type="radio" name="color" value="green"> Green

<div class="yellow msg">You have selected Yellow</div>
<div class="red msg">You have selected Red</div>
<div class="green msg">You have selected Green</div>

这是一个示例：根据单选按钮点击显示/隐藏 DIV

You can use jQuery’s show() and hide() methods. Like below:

JQuery:

  $(document).ready(function(){
    $('input[type="radio"]').click(function(){
      var val = $(this).attr("value");
      var target = $("." + val);
      $(".msg").not(target).hide();
      $(target).show();
    });
  });

HTML:

<input type="radio" name="color" value="yellow"> Yellow
<input type="radio" name="color" value="red"> Red
<input type="radio" name="color" value="green"> Green

<div class="yellow msg">You have selected Yellow</div>
<div class="red msg">You have selected Red</div>
<div class="green msg">You have selected Green</div>

下面的代码非常适合我：

$(document).ready(function(){
    $('input[type="radio"]').click(function(){
        var inputValue = $(this).attr("value");
        var targetBox = $("." + inputValue);
        $(".box").not(targetBox).hide();
        $(targetBox).show();
    });
});
.box{
        color: #fff;
        padding: 20px;
        display: none;
        margin-top: 20px;
    }
    .red{ background: #ff0000; }
    .green{ background: #228B22; }
    .blue{ background: #0000ff; }
    label{ margin-right: 15px; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
        <label><input type="radio" name="colorRadio" value="red"> red</label>
        <label><input type="radio" name="colorRadio" value="green"> green</label>
        <label><input type="radio" name="colorRadio" value="blue"> blue</label>
    </div>
    <div class="red box">You have selected <strong>red radio button</strong> so i am here</div>
    <div class="green box">You have selected <strong>green radio button</strong> so i am here</div>
    <div class="blue box">You have selected <strong>blue radio button</strong> so i am here</div>

Below code is perfectly workd for me:

$(document).ready(function(){
    $('input[type="radio"]').click(function(){
        var inputValue = $(this).attr("value");
        var targetBox = $("." + inputValue);
        $(".box").not(targetBox).hide();
        $(targetBox).show();
    });
});
.box{
        color: #fff;
        padding: 20px;
        display: none;
        margin-top: 20px;
    }
    .red{ background: #ff0000; }
    .green{ background: #228B22; }
    .blue{ background: #0000ff; }
    label{ margin-right: 15px; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
        <label><input type="radio" name="colorRadio" value="red"> red</label>
        <label><input type="radio" name="colorRadio" value="green"> green</label>
        <label><input type="radio" name="colorRadio" value="blue"> blue</label>
    </div>
    <div class="red box">You have selected <strong>red radio button</strong> so i am here</div>
    <div class="green box">You have selected <strong>green radio button</strong> so i am here</div>
    <div class="blue box">You have selected <strong>blue radio button</strong> so i am here</div>

我写了一个简单的代码来了解如何在 jquery 中显示和隐藏单选按钮，它非常简单

<div id="myRadioGroup">

    Value Based<input type="radio" name="cars" checked="checked" value="2"  />

    Percent Based<input type="radio" name="cars" value="3" />
    <br>
    <div id="Cars2" class="desc" style="display: none;">
        <br>
        <label for="txtPassportNumber">Commission Value</label>
       <input type="text" id="txtPassportNumber" class="form-control" />
    </div>
    <div id="Cars3" class="desc" style="display: none;">
        <br>
        <label for="txtPassportNumber">Commission Percent</label>
       <input type="text" id="txtPassportNumber" class="form-control" />
    </div>
</div>
</div>

Jquery 代码

$(document).ready(function() {
    $("input[name$='cars']").click(function() {
        var test = $(this).val();

        $("div.desc").hide();
        $("#Cars" + test).show();
    });
});
