javascript - HTML5 自定义视频控件

Question

我希望替代按钮在点击时播放视频。当我点击按钮时，什么也没有发生。这没有正常的控制，我只是用标准按钮测试这个功能，但我没有得到任何响应。

var func = function(){
var video = document.getElementById('video');
var but = document.getElementById('play-pause');
but.addEventListener("click",function(){
    if (video.paused == true) {
        video.play();
    }else{
        video.pause();
    }
});
}
func();

html

  <div id="vid">
<video id="video" width="420" controls>
<source src="images/tutorialUPLOAD.mp4" type="video/mp4" />
<p> your browser does not support HTML5 video </p>
</video>



<div id="vidctrl">
<button type="button" id="play-pause">click here to start</button>
</div>
</div>

JS:-

jQuery(function ($) {
    //For adding play pause layer on top on the player
    $("#Layer").css({
        position: "absolute",
        top: $("#video").offset().top,
        left: $("#video").offset().left,
        width: $("#video").outerWidth(),
        height: $("#video").outerHeight()
    });

    //Switching play/pause image on the player
    $("#Layer").on("click", function (e) {

        var myVideo = $("#video")[0];
        if (myVideo.paused) {
            myVideo.play();
            $(this).addClass("pause");
        } else {
            myVideo.pause();
            $(this).removeClass("pause");
        }
    });

    //Toggle behaviour for play/pause 
    $("#video").on("click", function (e) {
        var myVideo = $(this)[0];
        if (myVideo.paused) {
            myVideo.play();
        } else {
            myVideo.pause();
        }
    });

    //Showing/Hiding layer on top of the player
    $("#video").on("mouseenter", function (e) {
        $("#Layer").toggle();
    });

    //Volume bar to control video volume
    $("#volume-bar").on("change", function () {
        var myVideo = $("#video")[0];
        myVideo.volume = $(this).val();
    });

    //Seek bar to sync with the current playing video
    $("#video").on("timeupdate", function () {
        var myVideo = $(this)[0];
        var value = (100 / myVideo.duration) * myVideo.currentTime;
        $("#seek-bar").val(value);
    });

    //Seek bar drag to move the current playing video at the time.
    $("#seek-bar").on("mouseup", function () {
        var myVideo = $("#video")[0];

        var currentTime = $("#seek-bar").val() / (100 / myVideo.duration);
        myVideo.currentTime = currentTime;
    });

    $("#seek-bar").on("mousedown", function () {
        var myVideo = $("#video")[0];
        myVideo.pause();
    });

});
