javascript - 样式化选择框

Question

我很难将页面顶部的选择框样式设置为看起来像下面的可折叠 DIV。当我的 API 返回 2 个对象时(当有 2 个选项可供选择时，我只需要进行此外观更改盒子)。我也不想使用一个插件，如果可以的话，它可以让你给按钮一个 onClick 函数来模拟下拉选择——这需要大量的重新开发等。

当有 2 个选项时，我想将它的样式设置为糟糕:

white plus sign added to the left of the select box

这是我用来设置按钮样式的一些代码:

var innerdiv = $('<div class="acc_list" data-role="collapsible" data-collapsed="true" data-theme="b" data-content-theme="b" ></div>');

这为 DIV 添加了可折叠功能。

我已经尝试将选择框添加到 DIV 中，但它似乎是在右下角添加的。

 <div id="selectBoxContainer" data-role="fieldcontain">
              <select id="selectbox" class="combobox" name="selectbox" onchange="PolicyChange('selectbox')"></select>
          </div>

我检查数据是否包含两个对象，如果是:

  if (parseInt(policies.length) > 1)
{
    select.removeClass('combobox');
    changeBox.addClass('ui-collapsible-heading-toggle ui-btn ui-btn-icon-left ui-icon-plus ui-btn-b');
}

下面是我的 CSS 页面:

尝试以下响应后 - 我得到了白色加号，但它位于左下角 - 似乎无法使其与文本内联。很难在图像中看到，但十字在那里但不是内联:

Top of the cross on the bottom left of the text

还有什么建议吗？

Answer 1

jQM 选择小部件具有用于将图标放在左侧和选择要显示的图标的属性(data-iconpos="left"data-icon="plus"):

<div id="selectBoxContainer" data-role="fieldcontain">
      <select id="selectbox" class="combobox" name="selectbox" data-iconpos="left" data-icon="plus" >
          <option val="1">Option 1</option>
          <option val="2">Option 2</option>
      </select>          
</div>

然后，如果您想隐藏图标后面的灰色圆盘，以便只显示白色加号，请使用此 CSS:

#selectBoxContainer .ui-select .ui-btn-icon-left::after {
    background-color: transparent !important;
}
