  1. POJquery is not allowing line breaks in text areas

    copied!<p>I'm having a weird issue. When adding support for Jquery 1.7.2, I am unable to add line-breaks to textareas in forms. When I click, enter, nothing happens.</p> <p>I fiddled with the source code in jquery, and found that if I commented out the following code (on line 4845)</p> <pre><code>for ( var type in Expr.match ) { Expr.match[ type ] = new RegExp( Expr.match[ type ].source + (/(?![^\[]*\])(?![^\(]*\))/.source) ); Expr.leftMatch[ type ] = new RegExp( /(^(?:.|\r|\n)*?)/.source + Expr.match[ type ].source.replace(/\\(\d+)/g, fescape) ); } </code></pre> <p>the ability to add line breaks was restored. I'm not seeing anyone else having this issue, so I'm guessing something else is going on. However, my question is: what is the purpose of the code above (I'm not very javascript-savvy), and does removing it pose any risk? I'd like to just remove the code and restore line break ability to textareas, but don't want to bork the site unknowingly. I did notice that after doing this, I'm seeing an error in the js console:</p> <pre><code>Uncaught TypeError: Cannot call method 'exec' of undefined -- jquery.js:4185 </code></pre> <p>Any help would be greatly appreciated!</p> <hr> <p>Here is some code sample. The html:</p> <pre><code> &lt;form class="form-input" method="post"&gt; &lt;fieldset&gt; &lt;ol&gt; &lt;li&gt; &lt;label for="activity_type_id"&gt;Activity Type&amp;nbsp;&lt;em&gt;*&lt;/em&gt;&lt;/label&gt; &lt;select name="activity_type_id"&gt;&lt;option value="17" label="Call"&gt;Call&lt;/option&gt;&lt;option value="23" label="Connectivity Meeting"&gt;Connectivity Meeting&lt;/option&gt;&lt;option value="22" label="Conversation"&gt;Conversation&lt;/option&gt;&lt;option value="16" label="Email (incoming)"&gt;Email (incoming)&lt;/option&gt;&lt;option value="15" label="Email (outgoing)"&gt;Email (outgoing)&lt;/option&gt;&lt;option value="19" label="Implementation Notes"&gt;Implementation Notes&lt;/option&gt;&lt;option value="20" label="Meeting Minutes"&gt;Meeting Minutes&lt;/option&gt;&lt;option value="18" label="Task"&gt;Task&lt;/option&gt;&lt;option value="21" label="Tip / Unusual Attribute"&gt;Tip / Unusual Attribute&lt;/option&gt;&lt;/select&gt; &lt;/li&gt; &lt;li&gt; &lt;label for="summary"&gt;Summary&amp;nbsp;&lt;em&gt;*&lt;/em&gt;&lt;/label&gt; &lt;input size="40" maxlength="80" id="summary" name="summary" value=""/&gt; &lt;/li&gt; &lt;li&gt; &lt;label for="details"&gt;Details&amp;nbsp;&lt;/label&gt; &lt;textarea class="wide" name="details" id="details" rows="10" columns="80"&gt;&lt;/textarea&gt; &lt;/li&gt; &lt;/ol&gt; &lt;/fieldset&gt; &lt;input id="submit" name="addactivity" value="Add Activity" type="submit" /&gt; &lt;/form&gt; </code></pre> <p>And the javascript that isn't included with other plugins:</p> <pre><code>&lt;script&gt; // Dynamic lookup of C2 companies $(document).ready(function () { $(window).keydown(function(event) { if(event.keyCode == 13) { event.preventDefault(); return false; } }); $("#search_input").autocomplete( { source: function(request,response) { $("#loading-search").show(); $("#no-results").hide(); $.getJSON("/services/json/cust_search.php",request,function(data) { response(data); $("#loading-search").hide(); if (data.length == 0) { $("#no-results").show(); } else { $("#no-results").hide(); } }); }, minLength: 3, select: function(event,ui) { $("#search_input").hide(); $("#search_input").val(ui.item.value); $("#search_source").val(ui.item.source); $("#search-form").submit(); } }); }); &lt;/script&gt; &lt;script type="text/javascript"&gt; //--------------------------------------------------------------------------- // Hide all the submenus on start. When a non-expanded menu is clicked, // expand that menu while collapsing the menu above it. If a menu is // clicked when its expanded, collapse. //--------------------------------------------------------------------------- $(function() { // $("dd:not(:first)").hide(); $("dd").hide(); $("#menu-nexmark").slideDown("fast"); $("dt a").click(function() { var curr_dd = $(this).parent().next(); if (curr_dd.css("display") != "none") { $("dd:visible").slideUp("medium"); return; } $("dd:visible").slideUp("slow"); curr_dd.slideDown("slow"); return false; }); }); &lt;/script&gt; </code></pre>
