Question

Currently I have four separate sections: Sole, Collar, Lining and Tongue. In each section there is the option of selecting a material, the code below is an example of two of the sections.

<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>

I have created the divs so that when they are clicked on it takes the id and passes it to the value of a hidden input tag.

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

The problem I am having is that if I select leather for the Sole section for example it populates all four hidden inputs like in the code below. Is there a simple way to have the hidden input only apply to the section it relates to?

<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">

I’m also using JavaScript to loop over an array of panels and 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">';

}

below is the code that passes the value to the hidden field

$('.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

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);
});

注意：

（1）仅使用this.id（纯javascript）代替$(this).attr('id')，因为它更快，更容易输入。对于这个例子，他们将工作相同。要对所有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，您将得到如下数组：array('sole','leather') - 而[1]选择位置1处的元素（皮革）

（3）要将材料（正绒面革）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') - 这是唯一的隐藏领域。

（4）在jsFiddle演示中，隐藏的字段仅被取消隐藏，以便您可以在字段内看到正在更新的值。

Answer 2

You could add another attribute: data-segment

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

and then you can use

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

to select the correct input-field

Answer 3

仅用于演示目的，将输入类型保留为文本。

＆＃13;

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
              }
}

＆＃13;

<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">
