coldfusion - How do I unhide a CFDIV that has dynamic content with AJAX binding itself? -

-

i have following cfselect tags used populate text input:

<cfselect id="this" name="this" bind="cfc:data.getthis()" bindonload="true" />  <cfselect id="that" name="that" bind="cfc:data.getthat({p1})" />  <cfselect id="theother" name="theother" bind="cfc:data.gettheother({p1}, {p2})" />

the text input value needs submitted in form:

<cfform name="additem" method="post" action="somepage.cfm">     <cfinput          type="text"          id="item"          name="item"          bind="cfc:data.getresult({this}, {that}, {theother})" /><br />      <cfinput          type="submit"          name="addbutton"          value="add item" /> </cfform>

i want form , it's contents visible only when 3 selections have been made, , there value text input. best way this? i'm assuming use of cfdiv best way, i'm not sure how load dynamic content (the cfinputs) way.

<cfselect id="this" name="this" bind="cfc:data.getthis()" bindonload="true" onchange="toggleform();" /> <cfselect id="that" name="that" bind="cfc:data.getthat({p1})" onchange="toggleform();" /> <cfselect id="theother" name="theother" bind="cfc:data.gettheother({p1}, {p2})" onchange="toggleform();" />  <div id="theform" style="display:none"> <cfform name="additem" method="post" action="somepage.cfm">     <cfinput          type="text"          id="item"          name="item"          bind="cfc:data.getresult({this}, {that}, {theother})" /><br />      <cfinput          type="submit"          name="addbutton"          value="add item" /> </cfform> </div>  <script type="text/javascript">     function toggleform(){         var = document.getelementbyid("this").selectedindex;         var b = document.getelementbyid("that").selectedindex;         var c = document.getelementbyid("theother").selectedindex;         if (a > -1 && b > -1 && c > -1){             document.getelementbyid("theform").style.display = "";         }     } </script>

personally simplify js bit using jquery, don't know if you're using jquery on site, , don't want "use jquery" empty answer; should work without jquery, should want/need go without it. (but jquery awesome!)

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
