js implements copy log

Interpret network status   

var img = new Image();
img.src = 'https://www.baidu.com/favicon.ico?_t=' + Date.now();
img.οnlοad=function(){
    if (callback) callback(true)
};
img.οnerrοr=function(){
    if (callback) callback(false)
};

Realize replication (to prevent continuous replication when the network is disconnected)

copybox.oncopy = () => {
    let routeName = vm.$route.name;
    if(pageConfig.includes(routeName)){
        if(vm.remaminCount<=0){
            vm.copy("Please No Copies");
            this.$Message.warning("Your copy times for the day have been exhausted");
            return false
        }
        let selectedStr = window.getSelection().toString();
        let copyContent = selectedStr.replace(/\s*/g,'');
        vm.copy("Please No Copies");
        let params ={
            activityId: this.$route.params.id,
            copyContent:copyContent,
            page:routeName,
            contentLength:copyContent.length,
        }
        try{
            vm.addLog(params,selectedStr)
        }catch (e) {
            return false
        }

    }
}

False replication

copy(val) {
    var oInput = document.createElement('input');
    oInput.value = val;
    document.body.appendChild(oInput);
    oInput.select(); // select object
    document.execCommand("Copy"); // execute browser copy command
    oInput.className = 'oInput';
    oInput.style.display='none';
},
