将四个单独的值保存到四个隐藏字段

Question

目前我有四个独立的部分：Sole、Collar、Lining 和 Tongue。在每个部分中都有 selecting a material 的选项，下面的代码是其中两个部分的示例。

<div class="sole_panel container active">
    <h3>sole</h3>
    <div id="sole_leather" class="material-btn">leather</div>
    <div id="sole_suade" class="material-btn">suade</div>
    <div id="sole_nubuck" class="material-btn">nubuck</div>
</div>
<div class="collar_panel container">
    <h3>collar</h3>
    <div id="collar_leather" class="material-btn">leather</div>
    <div id="collar_suade" class="material-btn">suade</div>
    <div id="collar_nubuck" class="material-btn">nubuck</div>
</div>

我创建了 div，这样当它们被点击时，它会获取 id 并将其传递给隐藏输入标签的值。

<input id="sole" class="material-value" type="hidden" value="sole_leather">

我遇到的问题是，如果我 select 皮革用于鞋底部分，例如它会填充所有四个隐藏的输入，如下面的代码所示。有没有一种简单的方法可以让隐藏的输入只应用于它相关的部分？

<div class="sole_panel container active"></div>
<input id="sole" class="material-value" type="hidden" value="sole_leather">
<div class="collar_panel container"></div>
<input id="collar" class="material-value" type="hidden" value="sole_leather">
<div class="lining_panel container"></div>
<input id="lining" class="material-value" type="hidden" value="sole_leather">
<div class="tongue_panel container"></div>
<input id="tongue" class="material-value" type="hidden" value="sole_leather">

我还使用 JavaScript 遍历一组面板和 materials

panelArray     = ['sole','collar','lining','tongue'];
materialArray  = ['leather','suade','nubuck'];

//loop over array to create selectors
for (x = 0; x < panelArray.length; x++) {

    mtr = '';
    clr = '';               
    var segments = panelArray[x];

    //loop over materials 
    for (y = 0; y < materialArray.length; y++) {

        var material = materialArray[y];
        //console.log(material);

        mtr += '<div class="material-btn" id="' + segments + '_' + material + '">' + material + '</div>';
    }                 

    container += '<div class="' + segments + '_panel container"><h3>' + segments + '</h3>';
    container +=        mtr;
    container +=   '<div class="colour-container">';
    container +=        clr;
    container +=   '</div>';
    container += '</div>';
    container += '<input id="' + segments + '" class="material-value" type="hidden">';

}

下面是将值传递给隐藏字段的代码

$('.material-btn').on('click', function() {              

    $('.material-btn').removeClass('select');
    $(this).addClass('select');

    // passes material type selction to hidden field
    var value = $(this).attr('id');    
    var result = $('.material-value').attr('value', value);
    //console.log(result);
});

Answer 1

您可以添加另一个属性：data-segment

mtr += '<div class="material-btn" id="' + segments + '_' + material + '" data-segment="' + segments + '">' + material + '</div>';

然后你可以使用

var value = $(this).attr('id');    
var result = $($(this).data('segment')).attr('value', value);

到select正确的输入字段

Answer 2

试试这个：

jsFiddle Demo

$('.material-btn').click(function(){
    var part = this.id.split('_')[0];
    var matl = this.id.split('_')[1];
    $('#'+part).val(matl);
});

备注：

(1) 使用 this.id（纯粹的 javascript）而不是 $(this).attr('id') 只是因为它更快一点，而且更容易打字。对于此示例，它们的工作方式相同。对所有 jQuery 执行完全相同的操作：var matl = $(this).attr('id').split('_')[1];

(2) this.id.split('_')[1] 获取 id，例如 sole_leather，并将其转换为数组，在每个 _ 字符处拆分字符串。因此，您将得到一个像这样的数组：array('sole','leather')——并且 [1] 选择位置 1 的元素（皮革）

(3) 为了将 material (nubuck) 保存到零件（鞋底）隐藏字段中，我们使用在步骤 2 中创建的存储变量。$('#'+part) 变为 $('#sole') -这是唯一部分隐藏字段的ID。

(4) 在 jsFiddle 演示中，隐藏字段只是取消隐藏，以便您可以看到字段内正在更新的值。

/*

*/
$('.material-btn').click(function(){
    var part = this.id.split('_')[0];
    var matl = this.id.split('_')[1];
    $('#'+part).val(matl);
});

Answer 3

仅出于演示目的，将输入类型保留为文本。

var a = document.querySelectorAll('.material-btn');
for(i=0;i<a.length;i++){
    a[i].onclick = function(){
                var type= this.getAttribute('target');
                document.getElementById(type).value = this.innerHTML
              }
}

<div class="sole_panel container active">
    <h3>sole</h3>
    <div id="sole_leather" class="material-btn" target="sole">leather</div>
    <div id="sole_suade" class="material-btn" target="sole">suade</div>
    <div id="sole_nubuck" class="material-btn" target="sole">nubuck</div>
</div>
<div class="collar_panel container">
    <h3>collar</h3>
    <div id="collar_leather" class="material-btn" target="collar">leather</div>
    <div id="collar_suade" class="material-btn" target="collar">suade</div>
    <div id="collar_nubuck" class="material-btn" target="collar">nubuck</div>
</div>

<div class="sole_panel container active"></div>
<input id="sole" class="material-value" type="text" value="sole_leather">
<div class="collar_panel container"></div>
<input id="collar" class="material-value" type="text" value="sole_leather">
<div class="lining_panel container"></div>
<input id="lining" class="material-value" type="text" value="sole_leather">
<div class="tongue_panel container"></div>
<input id="tongue" class="material-value" type="text" value="sole_leather">
