Selectpicker (bootstrap-select) unfocus onchange

Question

我正在使用隐藏的锚点来取消引导选择的焦点，如下所示：

HTML：

<select id="SelectAddress" name="SelectAddress" class="selectpicker" title="Select an address" data-header="Select an address">
    <option id="1" value="1" selected >First address</option>
    <option id="2" value="2"  >Second address</option>
</select>

jQuery：

$("#SelectAddress").on("change", function() {
//...mycode...
  $("#AFocus").focus();
});

$("#AFocus").focus(); 使选择选择器失去焦点，但它也使目标页面上升。焦点在页面顶部，所以...

如何在不滚动页面的情况下不使用像我的AFocus 这样的锚标记来取消选择选择器的焦点？

这是一个示例：http://jsfiddle.net/ya0o7hzb/ 向下滚动页面以查看引导选择。

bootstrap-select 会像这样在 DOM 中添加一些 HTML：

<div class="btn-group bootstrap-select"><button type="button" class="btn dropdown-toggle btn-default" data-toggle="dropdown" role="button" data-id="SelectAddress" title="Address 1" aria-expanded="false"><span class="filter-option pull-left">Address 1</span>&nbsp;<span class="bs-caret"><span class="caret"></span></span></button><div class="dropdown-menu open" role="combobox" style="padding-top: 0px; max-height: 297px; overflow: hidden; min-height: 37px;"><div class="popover-title"><button type="button" class="close" aria-hidden="true">×</button>Select an address</div><ul class="dropdown-menu inner" role="listbox" aria-expanded="false" style="max-height: 248px; overflow-y: auto; min-height: 0px;"><li data-original-index="1" class="selected"><a tabindex="0" class="" data-tokens="null" role="option" aria-disabled="false" aria-selected="true"><span class="text">Address 1</span><span class="glyphicon glyphicon-ok check-mark"></span></a></li><li data-original-index="2" class=""><a tabindex="0" class="" data-tokens="null" role="option" aria-disabled="false" aria-selected="false"><span class="text">Address 2</span><span class="glyphicon glyphicon-ok check-mark"></span></a></li></ul></div><select id="SelectAddress" name="SelectAddress" class="selectpicker" title="Select an address" data-header="Select an address" onchange="blur_picker('SelectAddress')" tabindex="-98"><option class="bs-title-option" value="">Select an address</option>

所以你必须blur()包含类btn的按钮：

$(".btn").blur();

试试这个。这可能会奏效。

<select id="SelectAddress" name="SelectAddress" class="selectpicker" title="Select an address" data-header="Select an address" onChange="blur_picker('SelectAddress')">
<option id="1" value="1" selected >First address</option>
<option id="2" value="2"  >Second address</option>

function  blur_picker ( element ) {
element = document.getElementById(element);
element.blur;
  }

希望这会有所帮助！
