[英]jQuery and onclick html function callback
Let's say we have like 3 functions: 假设我们有3个函数:
// Notice there are no $(document).ready function
function third(par)
{
// uses jQuery.fadeIn() and jQuery.fadeOut()
}
function second()
{
// do normal javascript
third('Something')
}
function main()
{
var response = $.ajax() // an ajax call with jQuery
}
Now let's take a look at an HTML page 现在让我们看一下HTML页面
<button onclick="main()">Click me, please</button>
It seems that functions define inside $(document).ready
are unavailable out side, so main()
will be undefined if putted inside $(document).ready
I've checked the actions of each function with FireBug and i can tell you this: 似乎函数在$(document).ready
内部定义是不可用的,所以如果放在$(document).ready
, main()
将是未定义的$(document).ready
我已经用FireBug检查了每个函数的动作,我可以告诉你这个:
main()
function is called and the ajax call called returning the right data. 调用main()
函数,调用ajax调用返回正确的数据。 second()
function is called successfully second()
函数被成功调用 third()
function is called but an error occur: fadeIn() is not defined as any other jQuery functions. 调用third()
函数但发生错误:fadeIn()未定义为任何其他jQuery函数。 My question is: what should i do to attach a jQuery function to an HTML onclick event caller? 我的问题是:如何将jQuery函数附加到HTML onclick事件调用者?
$ ('button').click(main);
$ ('button').click(main);
inside document ready 内部文件准备好了
or 要么
var main;
$(document).ready(function(){
main = function(){...}
...
});
