Uniapp implementation forbids video drag fast forward

In the process of project development , It's hard to avoid using video Video Tags . According to customer requirements , The video can only be viewed normally , Cannot fast forward manually , The following is the implementation method ：

<!--1.video label -->
<video id="myVideo" @timeupdate="videoFun" :src="videourl" initial-time="initial_time" >


<script> export default {
       data() {
       //2.data Data section  return {
       videourl: "https://vd3.bdstatic.com/mda-me38qw5ayq6m5x6k/sc/cae_h264/1620080580731464743/mda-me38qw5ayq6m5x6k.mp4?v_from_s=hkapp-haokan-nanjing&auth_key=1654941744-0-0-e46a5e5c83b069fcaf54124cd256af20&bcevod_channel=searchbox_feed&pd=1&cd=0&pt=3&logid=1944747745&vid=1074518001243819841&abtest=102599_2-102777_6-102784_1-17451_1-3000225_3-3000232_1&klogid=1944747745", video_real_time: 0, // Real time playback progress  nitial_time: '', // Video jump progress   second  } }, onLoad(option) {
       //3.onload part  this.initial_time = '0' // Video progress  }, methods: {
       //4. Method section  videoFun(e){
       var isReady = 1; //  Whether to enable video fast forward  1  Do not turn on  // Jump to the specified playback position  initial-time  Time is seconds  let that = this; // Total playing time  var duration = e.detail.duration // Real time playback progress   Number of seconds  var currentTime = parseInt(e.detail.currentTime) // Current video progress  // console.log(" Play the video to " + currentTime + " second ")// View the playing time , In seconds  if (that.video_real_time == 0) {
       var jump_time = parseInt(that.initial_time) + parseInt(that.video_real_time) } else {
       var jump_time = parseInt(that.video_real_time) } if (isReady == 1) {
       if (currentTime > jump_time && currentTime - jump_time > 3) {
       let videoContext = wx.createVideoContext('myVideo') videoContext.seek(that.video_real_time) wx.showToast({
       title: ' I haven't watched the video completely , Don't fast forward ', icon: 'none', duration: 2000, }) } } that.video_real_time = currentTime // Real time playback progress  } } } </script>
