视频的currentTime无法修改，自动跳到0

Question

        opro.onchange = function() {//拖动range改变currentTime
        var ovideo=document.getElementsByClassName("video")[0];
        ovideo.load();
        var son = document.getElementById("purse");
        if(p == 0) {
            son.src = "../img/开始.png";
            ovideo.play();
            p = 1;
        }
        ovideo.currentTime = opro.value;  //opro是一个range。
        otito.innerText = turnTime(ovideo.currentTime);
        };

问题就是每次拖动range后进度自动跳到0

Answer 1

//下面2句放到放opro.onchange函数外，要不每次拖动后video.load从头开始，currentTime重置为0，从而触发timeupdate更新orpo.value为0了

有帮助麻烦点个采纳【本回答右上角】，谢谢~~

var ovideo=document.getElementsByClassName("video")[0];
ovideo.load();
opro.onchange = function() {
//下面这2句放到opro.onchange外，
//var ovideo=document.getElementsByClassName("video")[0];
// ovideo.load();
var son = document.getElementById("purse");
if(p == 0) {
son.src = "../img/开始.png";
ovideo.play();
p = 1;
}
ovideo.currentTime = opro.value;
otito.innerText = turnTime(ovideo.currentTime);//turnTime就是用来转换单位的
console.log(opro.value);
};
