Question

我在表单中有一个输入框。我在这个输入框中使用easyautocomplete插件。当我在input-group-addon外面有输入框时，输入框的宽度适当。但是，当我在input-group-addon中添加它时，宽度会减小/折叠。（见截图）

HTML input-group-addon

<div class="form-group col-md-9">
  <label for="taskname">Task Name</label>
  <div class="input-group">
    <span class="input-group-addon"><i class="fas fa-anchor"></i></span>
    <input class="form-control" id="taskname" name="taskname" required autocomplete="off" maxlength="50" placeholder="Name" value="<?php echo h($dataset['taskname']); ?>">
  </div>
  <small class="form-text text-muted">Select Task name from auto suggestion or type your own </small>
</div>

HTML 没有 input-group-addon

<div class="form-group col-md-9">
  <label for="taskname">Task Name</label>
    <input class="form-control" id="taskname" name="taskname" required autocomplete="off" maxlength="50" placeholder="Name" value="<?php echo h($dataset['taskname']); ?>">
  <small class="form-text text-muted">Select Task name from auto suggestion or type your own </small>
</div>

的Javascript

$("#taskname").easyAutocomplete(tasknameoption);
var tasknameoption = {
  url: "/task/tasklistapi.php",
  getValue: "tasklistname",
  adjustWidth: false,
  requestDelay: 500,
  list: {
    maxNumberOfElements: 10,
    match: {enabled: true},
    onSelectItemEvent: function() {
      var value = $("#taskname").getSelectedItemData().iscomp;
      $("#iscomp").val(value).trigger("change");
    }
  }
};

当评论上述javascript时，表单如下所示

我尝试过的事情（但没有奏效）：

根据Github

adjustWidth: false

根据SO和SO

inline

Answer 1

实际上，这要容易得多。只需将类添加到初始化程序。示例：

var options = {
    data: ["Cyclops", "Storm", "Mystique", "Wolverine", "Professor X", "Magneto"],
    theme: "dark", **cssClasses: 'col'**
};
$("#theme").easyAutocomplete(options);

Answer 2

显然，EasyAutocomplete插件将<input class="form-control">包装到另一个<div class="easy-autocomplete">元素中。通过该修改，它打破了正确input-group样式所需的Bootstrap标记。不幸的是，我没有找到EasyAutocomplete的选项来控制它如何更改 DOM 。

为了克服这个问题，你有两个我能想到的解决方法。

您可以修改Bootstrap css 以解决新标记问题。最简单的方法是将修改后的 scss 文件重新编译为新的 css 。但是，这也可能导致容易出错的结果。
然而，第二个选项是使用javascript进一步修改标记。

我认为后者更容易实现，所以我在下面的例子中证明了这一点。

＆＃13;

// Init `easyAutocomplete`
var tasknameoption = {
    adjustWidth: false,
    data: ["blue", "green", "pink", "red", "yellow"]
};
$("#taskname").easyAutocomplete(tasknameoption);

// Fixing markup
$('.easy-autocomplete').closest('.input-group').each(function(i, inputGroup) {
    $(inputGroup).removeClass('input-group');
    $autocomplete = $(inputGroup).find('.easy-autocomplete');
    $(inputGroup).find('.input-group-addon').prependTo($autocomplete);
    $autocomplete.addClass('input-group');
});

＆＃13;

.easy-autocomplete-container {
    top: 100%;
}

＆＃13;

<div class="form-group col-md-9">
    <label for="taskname">Task Name</label>
    
    <div class="input-group">
        <span class="input-group-addon"><i class="fa fa-anchor"></i></span>
        <input class="form-control" id="taskname" name="taskname" required autocomplete="off" maxlength="50" placeholder="Name">
    </div>

    <small class="form-text text-muted">Select Task name from auto suggestion or type your own </small>
</div>

＆＃13;

根据您的初始标记，我猜您使用的是Bootstrap 4 Beta 2 。请务必注意 Beta 3 ，并且更改也包括输入组组件的样式。因此，对于最新的beta版本，标记和“重置”脚本将如下所示。

＆＃13;

// Init `easyAutocomplete`
var tasknameoption = {
    adjustWidth: false,
    data: ["blue", "green", "pink", "red", "yellow"]
};
$("#taskname").easyAutocomplete(tasknameoption);

// Fixing markup
$('.easy-autocomplete').closest('.input-group').each(function(i, inputGroup) {
    $(inputGroup).removeClass('input-group');
    $autocomplete = $(inputGroup).find('.easy-autocomplete');
    $(inputGroup).find('.input-group-prepend').prependTo($autocomplete);
    $autocomplete.addClass('input-group');
});

＆＃13;

.easy-autocomplete-container {
    top: 100%;
}

＆＃13;

<div class="form-group col-md-9">
    <label for="taskname">Task Name</label>
    
    <div class="input-group">
        <div class="input-group-prepend">
            <span class="input-group-text" id="basic-addon1">
                <i class="fa fa-anchor"></i>
            </span>
        </div>

        <input class="form-control" id="taskname" name="taskname" required autocomplete="off" maxlength="50" placeholder="Name" aria-describedby="basic-addon1">
    </div>

    <small class="form-text text-muted">Select Task name from auto suggestion or type your own </small>
</div>

注意：正如您在示例中所看到的，仍然需要为EasyAutocomplete选项设置adjustWidth: false。此外，还有一个正确显示的课程.easy-autocomplete-container。
