রোল্যান্ড Bouman এর উত্তর ভাল, সহজ ভ্যানিলা উপায়। আমি জেকিউ প্লাগগুলিতে কিছু প্রচেষ্টা লক্ষ্য করেছি, তবে সেগুলি কেবল আমার পক্ষে যথেষ্ট "পূর্ণ" বলে মনে হচ্ছে না, তাই আমি নিজের তৈরি করেছি। এখন পর্যন্ত একমাত্র ধাক্কা সরাসরি কল না করেই গতিযুক্ত যুক্ত অ্যাটর্সগুলিতে অ্যাক্সেস করতে অক্ষম elm.attr('dynamicAttr')। তবে এটি jQuery উপাদান অবজেক্টের সমস্ত প্রাকৃতিক বৈশিষ্ট্য ফিরিয়ে দেবে।
প্লাগইন সাধারণ jQuery স্টাইল কলিং ব্যবহার করে:
$(elm).getAttrs();
// OR
$.getAttrs(elm);
আপনি কেবল একটি নির্দিষ্ট অ্যাটর পাওয়ার জন্য দ্বিতীয় স্ট্রিং পরমও যুক্ত করতে পারেন। এটি একটি উপাদান নির্বাচনের জন্য সত্যই প্রয়োজন নেই, যেমন jQuery ইতিমধ্যে সরবরাহ করে $(elm).attr('name'), তবে, আমার প্লাগইনটির সংস্করণটি একাধিক রিটার্নের অনুমতি দেয়। সুতরাং, উদাহরণস্বরূপ, একটি কল পছন্দ
$.getAttrs('*', 'class');
[]বস্তুর অ্যারে রিটার্নের ফলস্বরূপ {}। প্রতিটি বস্তু দেখতে পাবেন:
{ class: 'classes names', elm: $(elm), index: i } // index is $(elm).index()

<p>Roland Bouman's answer is the best, simple Vanilla way. I noticed some attempts at jQ plugs, but they just didn't seem "full" enough to me, so I made my own. The only setback so far has been inability to access dynamically added attrs without directly calling <code>elm.attr('dynamicAttr')</code>. However, this will return all natural attributes of a jQuery element object.</p>
<p>Plugin uses simple jQuery style calling:</p>
<pre class="default prettyprint prettyprinted"><code><span class="pln">$</span><span class="pun">(</span><span class="pln">elm</span><span class="pun">).</span><span class="pln">getAttrs</span><span class="pun">();</span><span class="pln">
</span><span class="com">// OR</span><span class="pln">
$</span><span class="pun">.</span><span class="pln">getAttrs</span><span class="pun">(</span><span class="pln">elm</span><span class="pun">);</span></code></pre>
<p>You can also add a second string param for getting just one specific attr. This isn't really needed for one element selection, as jQuery already provides <code>$(elm).attr('name')</code>, however, my version of a plugin allows for multiple returns. So, for instance, a call like</p>
<pre class="default prettyprint prettyprinted"><code><span class="pln">$</span><span class="pun">.</span><span class="pln">getAttrs</span><span class="pun">(</span><span class="str">'*'</span><span class="pun">,</span><span class="pln"> </span><span class="str">'class'</span><span class="pun">);</span></code></pre>
<p>Will result in an array <code>[]</code> return of objects <code>{}</code>. Each object will look like:</p>
<pre class="default prettyprint prettyprinted"><code><span class="pun">{</span><span class="pln"> </span><span class="kwd">class</span><span class="pun">:</span><span class="pln"> </span><span class="str">'classes names'</span><span class="pun">,</span><span class="pln"> elm</span><span class="pun">:</span><span class="pln"> $</span><span class="pun">(</span><span class="pln">elm</span><span class="pun">),</span><span class="pln"> index</span><span class="pun">:</span><span class="pln"> i </span><span class="pun">}</span><span class="pln"> </span><span class="com">// index is $(elm).index()</span></code></pre>
