You should be able to set these via the <a href="http://api.jquery.com/attr/"><code>attr()</code></a> or <a href="http://api.jquery.com/prop/"><code>prop()</code></a> functions in jQuery as shown below:

jQuery (&lt; 1.7):

<pre><code>// This will disable just the div
$("#dcacl").attr('disabled','disabled');
</code></pre>

or

<pre><code>// This will disable everything contained in the div
$("#dcacl").children().attr("disabled","disabled");
</code></pre>

jQuery (>= 1.7):

<pre><code>// This will disable just the div
$("#dcacl").prop('disabled',true);
</code></pre>

or

<pre><code>// This will disable everything contained in the div
$("#dcacl").children().prop('disabled',true);
</code></pre>

or

<pre><code>// disable ALL descendants of the DIV
$("#dcacl *").prop('disabled',true);
</code></pre>

Javascript:

<pre><code>// This will disable just the div
document.getElementById("dcalc").disabled = true;
</code></pre>

or

<pre><code>// This will disable all the children of the div
var nodes = document.getElementById("dcalc").getElementsByTagName('*');
for(var i = 0; i &lt; nodes.length; i++){
 nodes[i].disabled = true;
}
</code></pre>

blocks|key|243565|text|以下操作将选择所有子代元素并禁用它们：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|243566|$("#dcacl").find("*").prop("disabled",+true);|code-block|syntax|javascript|243567|但只有禁用某些元素类型才有意义:输入、按钮等，因此您需要一个更具体的选择器：|243568|$("#dcac1").find(":input").prop("disabled",true);

++++$("selector+for+whatever+you+want+to+click").one("click",function()+{
+++++++$dcac1kids.prop("disabled",false);
++++}
}|243576|我缓存了选择器的结果，假设您在页面加载和单击之间不会向div添加更多元素。而且我已经用.one()附加了单击处理程序，因为您没有指定重新禁用元素的要求，所以大概只需要处理一次事件。当然，如果合适的话，您可以将.one()更改为.click()。|offset|length|style|CODE|243577|entityMap|0|LINK|mutability|MUTABLE|url|http://api.jquery.com/one/^0|0|0|0|0|0|0|0|0|0|0|0|17|6|2W|6|35|8|17|6|0|0^^$0|@$1|2|3|4|5|6|7|1A|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|1B|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|1C|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|1D|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|1E|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|1F|8|@]|9|@]|A|$]]|$1|N|3|O|5|P|7|1G|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|1H|8|@]|9|@]|A|$]]|$1|R|3|-4|5|6|7|1I|8|@]|9|@]|A|$]]|$1|S|3|T|5|6|7|1J|8|@]|9|@]|A|$]]|$1|U|3|V|5|D|7|1K|8|@]|9|@]|A|$E|F]]|$1|W|3|X|5|6|7|1L|8|@$Y|1M|Z|1N|10|11]|$Y|1O|Z|1P|10|11]|$Y|1Q|Z|1R|10|11]]|9|@$Y|1S|Z|1T|1|1U]]|A|$]]|$1|12|3|-4|5|6|7|1V|8|@]|9|@]|A|$]]]|13|$14|$5|15|16|17|A|$18|19]]]]

The following selects all descendant elements and disables them:

<pre><code>$("#dcacl").find("*").prop("disabled", true);
</code></pre>

But it only really makes sense to disable certain element types: inputs, buttons, etc., so you want a more specific selector:

<pre><code>$("#dcac1").find(":input").prop("disabled",true);
// noting that ":input" gives you the equivalent of
$("#dcac1").find("input,select,textarea,button").prop("disabled",true);
</code></pre>

To re-enable you just set "disabled" to false.

<blockquote>
 I want to Disable them at loading the page and then by a click i can enable them
</blockquote>

OK, so put the above code in a document ready handler, and setup an appropriate click handler:

<pre><code>$(document).ready(function() {
 var $dcac1kids = $("#dcac1").find(":input");
 $dcac1kids.prop("disabled",true);

 // not sure what you want to click on to re-enable
 $("selector for whatever you want to click").one("click",function() {
 $dcac1kids.prop("disabled",false);
 }
}
</code></pre>

I've cached the results of the selector on the assumption that you're not adding more elements to the div between the page load and the click. And I've attached the click handler with <a href="http://api.jquery.com/one/" rel="noreferrer"><code>.one()</code></a> since you haven't specified a requirement to re-disable the elements so presumably the event only needs to be handled once. Of course you can change the <code>.one()</code> to <code>.click()</code> if appropriate.

blocks|key|247320|text|如果你想禁用所有的div控件，你可以尝试在要禁用的div上添加一个透明的div，你可以让它不可点击，也可以使用fadeTo创建一个禁用的外观。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|247321|尝尝这个。|247322|$('#DisableDiv').fadeTo('slow',.6);
$('#DisableDiv').append('<div+style="position:+absolute;top:0;left:0;width:+100%25;height:100%25;z-index:2;opacity:0.4;filter:+alpha(opacity+=+50)"></div>');|code-block|syntax|javascript|247323|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|$]]

If you want to disable all the div's controls, you can try adding a transparent div on the div to disable, you gonna make it unclickable, also use fadeTo to create a disable appearance.

try this.

<pre><code>$('#DisableDiv').fadeTo('slow',.6);
$('#DisableDiv').append('&lt;div style="position: absolute;top:0;left:0;width: 100%;height:100%;z-index:2;opacity:0.4;filter: alpha(opacity = 50)"&gt;&lt;/div&gt;');
</code></pre>

I am looking for a method to Enable and Disable the 
 div id="dcalc" and Its children.

<pre><code>&lt;div id="dcalc" class="nerkheArz"
 style="left: 50px; top: 150px; width: 380px; height: 370px;
 background: #CDF; text-align: center" &gt;
 &lt;div class="nerkh-Arz"&gt;&lt;/div&gt;
 &lt;div id="calc"&gt; &lt;/div&gt;
&lt;/div&gt;
</code></pre>

I want to Disable them at loading the page and then by a click i can enable them ?

This is what i have tried 

<pre><code>document.getElementById("dcalc").disabled = true;
</code></pre>
