免接口分享

实现免接口分享的逻辑：监听用户离开页面

var shareATimes = 0
var shareTTimes = 0
var hiddenProperty = 'hidden' in document ? 'hidden'
    : 'webkitHidden' in document ? 'webkitHidden'
        : 'mozHidden' in document ? 'mozHidden'
            : null
var visibilityChangeEvent = hiddenProperty.replace(/hidden/i, 'visibilitychange')
var onVisibilityChange = function () {
    if (!document[hiddenProperty]) {
        window.show_time = Date.now()
        if (show_time - hidden_time > 100) { // 用来判断用户离开页面事件
            // if (show_time - hidden_time > 0) {
            shareATimes += 1
            if (shareATimes > 4) {
                shareTTimes += 1
                setTimeout(share_tip(shareATimes, shareTTimes), 100) 
            } else {
                setTimeout(share_tip(shareATimes, -1), 100)
            }
        } else {
            console.log(11)
            // alert('分享失败')
        }
    } else {
        window.hidden_time = Date.now()
    }
}

监听用户是否离开页面 

document.addEventListener(visibilityChangeEvent, onVisibilityChange) // 监听

 分享方法的处理，可根据用户离开页面的次数依次处理

function share_tip(share_app_times, share_timeline_times) { // 分享处理
    console.log('处理了吗')

    if (share_timeline_times == -1) {
        if (shareATimes == 1) {
            $('#modal').css('animation', 'shakeOne 2s 2 linear')
            $('#fscg').html('发送成功<br>')
            $('#jx').html('请您继续分享视频至<br><span style="font-size: 1.3rem">\n' +
                '\t\t\t<span style="color: red;font-weight: bold">2</span>个微信群</span>\n' +
                '\t\t\t<br>分享后立即观看VIP免费视频')
        } else if (shareATimes == 2) {
            $('#modal').css('animation', 'shakeTwo 2s 2 linear')
            $('#jx').html('请您继续分享视频至<br><span style="font-size: 1.3rem">\n' +
                '\t\t\t<span style="color: red;font-weight: bold">1</span>个微信群</span>\n' +
                '\t\t\t<br>分享后立即观看VIP免费视频')
        } else {

        }
    }
}
