我想使用bootstrap css：
我写了一个jsfiddle来做我的测试：
http://jsfiddle.net/xr4uofje/
<div class="container">
<div class="col-lg-6">
<div class="input-group">
<input class="input-group-addon" size="8" type="text">
<span class="input-group-btn">
<select class="form-control"></select>
<button type="button" class="btn btn-default">Get</button>
</span>
</div>
</div>
</div>
解决方法
你可以把这种类型的元素
HTML
<div class="container">
<div class="col-lg-6">
<div class="input-group my-group">
<input type="text" class="form-control" name="snpid" placeholder="Test"/>
<select id="lunch" class="selectpicker form-control" data-live-search="true" title="Please select a lunch ...">
<option>Hot Dog,Fries and a Soda</option>
<option>Burger,Shake and a Smile</option>
<option>Sugar,Spice and all things nice</option>
<option>Baby Back Ribs</option>
<option>A really really long option made to illustrate an issue with the live search in an inline form</option>
</select>
<span class="input-group-btn">
<button class="btn btn-default my-group-button" type="submit">GO!</button>
</span>
</div>
</div>
<div>
CSS
.my-group .form-control{
width:50%;
}
JQUERY
if ( $.browser.webkit ) {
$(".my-group-button").css("height","+=1px");
}
