Change dialogWidth and dialogHeight's values

Question

The calendar web part is too wide and want to change dialogWidth and dialogHeight's values from 500px to 300px. Is it possible to change dialogWidth and dialogHeight of a web part like changing the table's width with javascript?

Thank you.

the code about dialogWidth/Height:

<div>
javascript:commonShowModalDialog(&#39;{SiteUrl}/_layouts/itemexpiration.aspx?ID={ItemId}&amp;List={ListId&#39;,&#39;center:1;
dialogHeight:500px;dialogWidth:500px;
resizable:yes;status:no;location:no;menubar:no;help:no&#39;,function GotoPageAfterClose(pageid){if(pageid == &#39;hold&#39;) {STSNavigate(unescape(decodeURI(&#39;{SiteUrl}&#39;))+&#39;/_layouts/hold.aspx?ID={ItemId}&amp;List={ListId}&#39;);return false;} 
if(pageid == &#39;audit&#39;) {STSNavigate(unescape(decodeURI(&#39;{SiteUrl}&#39;))+&#39;/_layouts/Reporting.aspx?Category=Auditing&amp;backtype=item&amp;
ID={ItemId}&amp;List={ListId}&#39;);return false;} if(pageid == &#39;config&#39;) {STSNavigate(unescape(decodeURI(&#39;{SiteUrl}&#39;))+&#39;/_layouts/expirationconfig.aspx?ID={ItemId}&amp;List={ListId}&#39;); return false;}}, null); return false;
</div>

I believe the answer to this is already on technet: How do I resize a dialog box once it's open?
