每次运行特定功能时执行Jquery [英] Execute Jquery every time a specific function runs
问题描述
每次特定函数运行时,是否可以执行某些操作,而不需要知道该函数的名称?
这将会是类似于绑定
var clicked = 0;
('#foo')。bind('click',function(){
clicked + = 1;
alert(clicked);
});
因此,每次使用ID foo
被点击后,它会向变量点击
添加1,这样我就知道它被点击了多少次。如果它是正确的语法,我想要做的就是以下的等价:
var fired = 0;
('my_function')。bind('run',function(){
fired + = 1;
alert(fired);
});
我不在乎在任何特定的情况下,您会一直能够找出关于这个函数的东西并使用它,我不想要工作,这就是我想要的答案:
如何在每次特定的时间执行某些操作函数运行,只是给出了函数的名称。如果这是不可能的,为什么不呢?
试试这样:
var temp = my_function,fired = 0;
my_function = function(){
fired ++;
temp.apply(this,arguments);
}
Is it possible to execute something every time a specific function runs without any knowledge about that function besides its name?
This would be similar to bind
var clicked = 0;
$('#foo').bind('click',function(){
clicked += 1;
alert(clicked);
});
So there, every time something with the ID foo
is clicked, it will add 1 to the variable clicked
so that I know how many times it has been clicked. What I want to do would be the equivalent of the following if it were correct syntax:
var fired = 0;
$('my_function').bind('run',function(){
fired += 1;
alert(fired);
});
I don't care if in any given situation you would be in, you would always be able to figure something out about the function and use that, I don't want work arounds, this is what I want for an answer:
How I can execute something everytime a specific function runs, just given the name of the function. If that is not possible, why not?
Try something like this:
var temp = my_function, fired = 0;
my_function = function() {
fired++;
temp.apply(this,arguments);
}
