1.布局

<input id="timeInput" class="timeInput" placeholder="设置秒数" size="7" maxlength="10" onkeyup="this.value=this.value.replace(/\D/g,'')"/>

样式

.process-text input{
    position: relative;
    background: transparent;
    height: 100%;
    font: bold;
    outline:none;
    z-index: 10;
}
  
.process-text input:read-only {
    border: 2px solid cadetblue;
}

逻辑

$(".timeInput").on("focus", function(){
    $(this).attr("readonly", "readonly");
});
 
$(".timeInput").on("blur", function(){
    $(this).css("border", "").removeAttr("readonly");
});
 
$(".timeInput").keydown(function(event){
    $this = $(this);
    if(event.which == "13") {
        if("" === $(this).val())
        {
            return;
        }
        $(".video")[0].currentTime = $(this).val();
        $video.play();
        $(this).val("");
    }
    if(57 >= event.keyCode && 48 <= event.keyCode)
    {
        $this.val($this.val() + (event.keyCode-48).toString());
    }
});
