setTimeOut Arrgument Passing [英] setTimeOut Arrgument Passing

问题描述

在JavaScript中我想使用 setTimeOut（）这样的函数

In JavaScript I want to use the setTimeOut() function like this

<script>    
var id=12;

setTimeOut("showGrid('i want to pass variable id here')",5000);

</script>

推荐答案

最好的方法是通过匿名功能到setTimeout。这个匿名函数将能够访问 id

The best way to do this would be to pass an anonymous function to setTimeout. This anonymous function will be able to access id

setTimeout(function() { showGrid(id); }, 5000);

将字符串传递给 setTimeout （而不是函数）通常被认为是邪恶的，因为字符串将是 eval 'd，应该避免。

Passing a string to setTimeout (instead of a function) is usually considered evil, since the string will be eval'd, and should be avoided.

另请注意，您的代码中有一个小错字：函数是 setTimeout ，而不是 setTimeOut （注意小写 o ）

Also note that you had a slight typo in your code: the function is setTimeout, not setTimeOut (note the lowercase o)

编辑

根据您的评论，代码如下所示：

Based on your comment, the code would look like this:

setTimeout(function() { document.getElementById().inerHTML = data; }, 500);

除了你需要将某种id传递给 document.getElementById

except of course you need to pass some sort of id to document.getElementById
