JavaScript implements method of passing parameters to setTimeout execution code_javascript skills

The example in this article describes how JavaScript implements passing parameters to the setTimeout execution code. Share it with everyone for your reference. The specific analysis is as follows:

The setTimeout function is the most critical function in JavaScript to achieve dynamic effects. But yesterday when I was writing code, I discovered that when the first parameter is a function call, parameters cannot be passed to the called function. This is really a very serious problem. It took me a long time to find out the problem, and I wasted a lot of time. .

I checked online later and found that this is actually a BUG in IE. There are many solutions, and I think the most awesome one is to rewrite the setTimeout function. . . This is too much trouble. . Here is a very simple method recommended. Just add the function{} keyword before the function you want to call.

function ShowMsg(x,y)
{
}
setTimeout(funtion(){ShowMsg(x,y)},1000);

This conveniently solves the problem of not being able to pass parameters.

I hope this article will be helpful to everyone’s JavaScript programming design.
