Browser basic attributes can be monitored,

Through the browser can monitor whether minimize or whether to switch to other page:

 
Document. The addEventListener (' visibilitychange ', function () {
Var isHidden=document. Hidden; 
If (isHidden) {
Alert (" your browser minimizes the, you cheated on "); 
} 
});

Through add events to the body can monitor to see if there is other software pop-up box, such as QQ pop-up box, youdao dictionary, such as:

 
<script> 
Document. The addEventListener (' visibilitychange ', function () {
Var isHidden=document. Hidden; 
If (isHidden) {
Alert (" your browser minimizes the, you cheated on "); 
} 
}); 

The function (aa) {
Alert (" do you have other software pop up "); 
} 
</script> 
<body onblur="aa ()" & gt;
