修改mui input键盘的enter(换行)键为搜索

正常输入框  // enter键为"换行"
<input type="search" class="mui-input-clear" placeholder="">

修改键盘enter键为搜索
<form action="#" onsubmit="return false;">   
    <input type="search" class="mui-input-clear" placeholder="">
</form> 

或者
<form @submit.prevent="formSubmit" action="javascript:return true">
    <input type="search" class="mui-input-clear" placeholder="">
</form>
