greasemonkey修改网页内指定函数

var mydiv =document.getElementById("myDIV");
mydiv.innerHTML="Replaced!!";
window.func =null;

方法二：编写inject代码

alert("hello2");

function embed() {
    window.func = null;
  
    var mydiv =document.getElementById("myDIV");
    mydiv.innerHTML="Replaced!!";
}


var script = document.createElement('script'); 
script.type = "text/javascript"; 
script.innerHTML = "(" + embed + ")()";
document.getElementsByTagName('head')[0].appendChild(script);
