Question

尝试根据使用mixin时有多少问题循环显示某些HTML。

我希望这段代码能在div上循环3次并将每个问题传递给input-label和input-field的混合，并吐出正确的html，好像我正在使用mixin只有文字。

PUG代码

- var questions = ['question one', 'question two', 'question three'];
- var answers = ['answer one', 'answer two', 'answer three'];

- for (var i = 0; i < questions.length; i++) {
    div.row.row-loose
        div.col-md-6
            +input-label(#{questions[i]})
        div.col-md-5
            +input-field()(val=#{answers[i]} disabled)
        - if(i == 0) {
            span &nbsp;   
        - }
        - else {
            div.col-md-1
                +button-default('Modify')                    
        - }
- }

输入label.pug

mixin input-label(label)
    label.control-label(class=attributes.class required for=attributes.id+'-'+label)
        if attributes.required
            span.required *
        =label+':'

输入field.pug

mixin input-field()
    input.form-control(type='text' class=attributes.class id=attributes.id value=attributes.value disabled=attributes.disabled readonly=attributes.readonly)

预期结果

<div class="row row-loose">
    <div class="col-md-6">
        <label class="control-label">question one</label>
    </div>
    <div class="col-md-5">
        <input class="form-control" type="text" disabled="disabled" val="answer one" />
    </div><span>&nbsp;   </span></div>
<div class="row row-loose">
    <div class="col-md-6">
        <label class="control-label">question two</label>
    </div>
    <div class="col-md-5">
        <input class="form-control" type="text" disabled="disabled" val="answer two" />
    </div>
    <div class="col-md-1">
        <button class="btn btn-default" type="button">Modify</button>
    </div>
</div>
<div class="row row-loose">
    <div class="col-md-6">
        <label class="control-label">question three</label>
    </div>
    <div class="col-md-5">
        <input class="form-control" type="text" disabled="disabled" val="answer three" />
    </div>
    <div class="col-md-1">
        <button class="btn btn-default" type="button">Modify</button>
    </div>
</div>

实际结果 - pugjs错误

27|                 div.row.row-loose
28|                     div.col-md-6
29|                         +input-label(#{questions[i]})
------------------------------------------^
30|                     div.col-md-5
31|                         +input-field()(val=#{questions[i]} disabled)
32|                     - if(i == 0) {

发现问题..

变量不需要插值，因为它被传递给mixin而不仅仅是文本。输入标签mixin调用应为+input-label(questions[i])

对于输入字段mixin调用，我的属性错误。它的value不是val。并删除插值。所以看起来像这样：+input-field()(value=answers[i] disabled)

pugJS将变量传递给循环中的mixin
