JSFiddle包装在onLoad？ [英] JSFiddle wrap in onLoad?

问题描述

我试图理解JSFiddle如何在'onLoad'中基于这个描述'包装'代码：
[1]： http://doc.jsfiddle.net/basic/introduction.html#javascript 。我已经看到onLoad被用在HTML的BODY标签中来加载函数。那么JSF（幕后）是如何包装每一个调用以及我在JS窗口中创建的每个函数？ AKA：

  onLoad =myfunc1（），myfunc2，alert（1）; 
  

如果是这样，那么当我选择jQuery作为框架时，我应该避免使用这种格式：

$ b $

  $（document）.ready（function（）{
 myfunc1 {（...）} 
 myfunc1 { （...）} 
 ... 
  

如果有骨架问题，请提前道歉。

解决方案

它们将所有JS放入< script> 标签中例如，如果您选择包含jQuery和<$ c $> onLoad 事件代码，

 < script type =text / conLoad 然后这就是jsfiddle的用法： javascript> 
 //<！[CDATA [
 $（window）.load（function（）{/ * your js here * /}）; 
 //]]> ; 
  
  

如果您不包含库， ：

 < script type =text / javascript> 
 //<！[CDATA [
 window.onl oad = function（）{/ *你的js在这里* /} 
 //]]> 
< / script> 
  

我假设他们也使用其他库特定的 load

使用 $（document）.ready（function（）{}）; $ c $>

I'm trying to understand how JSFiddle 'wraps' code in 'onLoad' based on this description: [1]: http://doc.jsfiddle.net/basic/introduction.html#javascript. I've seen onLoad being used in the HTML's BODY tag to load function(s). So does JSF (behind the scenes) wrap every call and every function I create int its JS window? AKA:

onLoad = "myfunc1(),myfunc2,alert(1);" 

If so then when I select jQuery as a framework, should I avoid using this format:

 $(document).ready(function(){
     myfunc1{(...)}
     myfunc1{(...)}
     ...

Apologize in advance if an armature question.

解决方案

They put all your JS inside <script> tags with the onLoad event code wrapped around it.

For example, if you choose to include jQuery and onLoad then this is what jsfiddle will use:

<script type="text/javascript">
    //<![CDATA[
        $(window).load(function(){ /* your js here */ });
    //]]>
</script>

If you don't include a library then they use:

<script type="text/javascript">
    //<![CDATA[
        window.onload=function(){ /* your js here */ }
    //]]>
</script>

I presume they also use other library specific load events depending on what you choose to include.

Using $(document).ready(function(){ }); isn't required when running your code in a fiddle.
