javascript - get and set string onmouseover js value

Question

I want to run some onmousedown function, but how can I run this function without onmousedown event, in twebbrowser?

Can you suggest me a proper function, please?

Answer 1

尝试将函数名称设置为 null，如下所示：

alert('test'); // will show 'test'
alert = null;
alert('test'); // will do nothing
