blocks|key|3043327|text|您可以在jQuery对象内创建一个名称空间，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3043328|$.mynamespace+=+{+

$.mynamespace.myVar2+=+"somethingElse";|3043331|请记住，任何名为'mynamespace‘的插件方法都将被覆盖，因此请确保使用合理的名称。|3043332|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

You can create a namespace inside the jQuery object, like so:

<pre><code>$.mynamespace = { 
 myVar : "something", 
 myVar2 : "somethingElse" 
}; 
</code></pre>

or:

<pre><code>$.mynamespace = {};
$.mynamespace.myVar = "something";
$.mynamespace.myVar2 = "somethingElse";
</code></pre>

Bear in mind, any plugin method named 'mynamespace' will be overwritten so be sure to use a sensible name.

blocks|key|305257|text|对我来说，处理这种情况的最好方法是在窗口对象中定义一个对象：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|305258|window.my_config+=
{
++++my_var1+:+1,
++++my_var1+:+2,
++++my_var1+:+3
};|code-block|syntax|javascript|305259|这将使您的作用域保持整洁和干净。当您使用window.my_config访问全局数据库时，任何查看代码的人都会知道正在访问全局数据库。|offset|length|style|CODE|305260|entityMap^0|0|0|K|G|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

For me the best way to handle this situation is to define an object in the window object:

<pre><code>window.my_config =
{
 my_var1 : 1,
 my_var1 : 2,
 my_var1 : 3
};
</code></pre>

This would keep your scope neat and clean. And whenever you would access the global using <code>window.my_config</code> anyone looking at the code would know that a global is being accessed.

blocks|key|3043351|text|您可以在全局作用域中创建哈希并将其用作命名空间：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3043352|MyNamepace={}
MyNamespace.newvar+=+'value'
//+MyNamespace.newvar+=>+'value'|code-block|syntax|javascript|3043353|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You can create a hash in the global scope and use it as a namespace:

<pre><code>MyNamepace={}
MyNamespace.newvar = 'value'
// MyNamespace.newvar =&gt; 'value'
</code></pre>

blocks|key|305244|text|仅与您分享我的实践，我会在所需的JavaScript文件中创建一个带有合理前缀的全局对象/var，就像我在一个页面上工作，该对象将是一个文本框，然后我会将其命名为：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|305245|g_TxtMyValue+=+'value';++++//+g_+specifies+it+to+be+a+global+variable,+it+is+one
+++++++++++++++++++++++++++//+of+the+many+conventions+used|code-block|syntax|javascript|305246|如果您有多个全局变量，则还可以有一个名称空间，例如：|305247|my_txt+=+{};++//+For+a+real+site+I+would+use+a+prefix+relative+to+the+project
++++++++++++++//+name+instead+of+"my".

my_txt.testValueOne+=+'Value+one';
my_txt.testValueOne+=+'Value+two';|305248|这些变量在初始化后，将在整个网站中可用。|305249|我希望这能帮到你。|305250|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

Just sharing my practice with you, I would make a global object/var in the required JavaScript file with a sensible prefix, as in if I am working on a page where this object will be a text box then I would name it:

<pre><code>g_TxtMyValue = 'value'; // g_ specifies it to be a global variable, it is one
 // of the many conventions used
</code></pre>

If you have more than one global variable, you can also have a namespace such as:

<pre><code>my_txt = {}; // For a real site I would use a prefix relative to the project
 // name instead of "my".

my_txt.testValueOne = 'Value one';
my_txt.testValueOne = 'Value two';
</code></pre>

These variables will be available to you throughout the website, after they have been initialized.

I hope this helps.

blocks|key|310268|text|只是一个简短的通知：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|310269|fancybox是否执行AJAX+(意思是:如果它在iFrame中加载，您应该将"parent“添加到close方法中)，如下所示：|310270|parent.$.fancybox.close();|code-block|syntax|javascript|310271|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Just a short notice:

Is the fancybox doing AJAX (meaning: if it loads within an iFrame, you should add "parent" to the close method), like this:

<pre class="lang-js prettyprint-override"><code>parent.$.fancybox.close();
</code></pre>

blocks|key|310277|text|使用下划线isEmpty()。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|310278|_.isEmpty('')将返回true。|310279|entityMap|0|LINK|mutability|MUTABLE|url|http://underscorejs.org/#isEmpty^0|5|9|5|9|0|0|0|D|G|4|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]]|D|@$9|S|A|T|1|U]]|E|$]]|$1|F|3|G|5|6|7|V|8|@$9|W|A|X|B|C]|$9|Y|A|Z|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

Use underscore <a href="http://underscorejs.org/#isEmpty" rel="nofollow"><code>isEmpty()</code></a>.

<code>_.isEmpty('')</code> will return <code>true</code>.

Currently I am working on a legacy web page that uses a ton of JavaScript, jQuery, Microsoft client JavaScript, and other libraries. The bottom line - I cannot rewrite the entire page from scratch as the business cannot justify it. So... it is what it is. Anyway, I need to pollute (I really tried not too) the global namespace with a variable. There are the three options I was thinking about -

<ol>
<li>Just store/retrieve it using a normal JavaScript declaration - <code>var x = 0;</code></li>
<li>Use jQuery to store/retrieve the value in a DOM tag - <code>$("body").data("x", 0);</code></li>
<li>Use a hidden form field, and set/retrieve the value with jQuery - <code>$("whatever").data("x", 0);</code></li>
</ol>

Is there a better way? I looked at the existing pile of code, and I do not believe the variable can be scoped in a function.

How to store a global value (not necessarily a global variable) in jQuery?

目前，我正在开发一个遗留网页，它使用了大量的JavaScript、jQuery、微软客户端JavaScript和其他库。底线-我不能从头开始重写整个页面，因为业务无法证明它的合理性。所以..。这就是它的本质。无论如何，我需要用一个变量污染全局名称空间(我真的没试过)。我想有三个选择-var x = 0;Use 只需使用普通的JavaScript声明-var x = 0;Use来存储/检索DOM标记
