Coldfusion 8 - How to submit a form using enter key

I have a page that contains a single field search form and a cfgrid. When I hit the eneter key, regardless of whether the text field is in focus or not the entire page refreshes instead of the search form being submitted. How do I fix this behavior? I do not want the page to ever refresh when hitting enter and I would like the form to be submitted on hitting enter only if there is a search term in the field.

oh right, we need to move the return false; to only happen on the Enter key..

both function and input tag have changed...
<script type="text/javascript">
 function doSearch(evt){
   evt = (evt) ? evt : event;
   var charCode = (evt.which) ? evt.which : evt.keyCode;
   if(charCode==13) {javascript:ColdFusion.Window.show('searchResults');return false;}
   else {return true;}
 }
</script>
 
 
<cfinput type="text" value="Search Term" name="searchTerm" onKeyPress="return doSearch(event);">

Open in new window

I assume you mean hitting enter when the focus is on the search field?  If so you could use a JavaScript function to trigger in the onBlur event of the searchfield

<input type="text" name="searchfield" size="10"onBlur="ProcessForm()">

<SCRIPT LANGUAGE="JavaScript">
<!-- hide

 function ProcessForm()
  {
if(document.yourformname.elements("searchfield").value!=""
{
document.yourformname.submit();
      }
}
//-->

</script>

Hmmm. Can you have an onBlur and an onClick event for the same button? I currently have an onClick event the launches a cfwindow. Below is my code for the button as it currently stands.
	<cfform name="clientSearch">
        <cfinput type="hidden" name="collname" value="searchDB">
        <cfinput type="text" value="Search Term" name="searchTerm" required="yes">
        <cfinput type="button" name="searchButton" value="Search" onClick="javascript:ColdFusion.Window.show('searchResults')" ><br />
	</cfform>

you can have onBlur and onClick together.   OnBlur fires when someone leaves a field, onClick fires when someone clicks the field/button.

You definitely do not want to execute a search onBlur.   Imagine putting your cursor into a search field and then you move to another field and the page automatically submits a search on you..

Thanks but please excuse my ignorance. What you are saying is that I can leave my onClick in place and add onKeyPress? Or is there a way to use onKeyPress to fire off both the submit and launch the cfwindow?

I am really new to programming so if you can help me out with what the code will look like that would be great.

Can you explain what you're trying to do?   Your initial question just asks to test for the Enter key to submit a form.  Where does the pop-up box come in?  

Are you trying to submit a form and open a new window at the same time?  Why both?   Are you thinking the form submit will appear in the new open window doing that?  (it won't)     What is in the pop-up?

Ahh. I overlooked that in my initial question. Sorry. I have a page with both a cfgrid and a cfform. THe form is a single text field and a single button. When the user enters a search terms and clicks the button a cfwindow opens (essentially a positioned div that loads another page). That all works great. The problem is that the window is only triggered by the onClick event. When a person hits enter after entering a search term that page refreshes instead of submitting the term to the cfwindow. Below is the code for the cfwindow that opens up.
<!--- cfform that opens the cfwindow with the search results --->
 
<cfform name="clientSearch">
   <cfinput type="hidden" name="collname" value="searchDB">
   <cfinput type="text" value="Search Term" name="searchTerm" required="yes">
   <cfinput type="button" name="searchButton" value="Search" onClick="javascript:ColdFusion.Window.show('searchResults')" >
</cfform>
 
 
<!--- cfwindow that displays the search results --->
 
 
<cfwindow center="true" width="610" height="500" name="searchResults"
        minHeight="400" minWidth="500" 
        title="Search Results" initshow="false"
        source="sresults.cfm?collname={clientSearch:collname}&searchTerm={clientSearch:searchTerm}"/>

So, you do NOT want to submit when the user presses enter.   You keep saying you do...

When the user presses enter you want to do the same action as onClick which is the javscript  show window command, you do NOT want to submit the form..



<script type="text/javascript">
 function doSearch(evt){
   evt = (evt) ? evt : event;
   var charCode = (evt.which) ? evt.which : evt.keyCode;
   if(charCode==13) {javascript:ColdFusion.Window.show('searchResults');}
 }
</script>
 
 
<cfinput type="text" value="Search Term" name="searchTerm" onKeyPress="doSearch(event);">

When I say submit when the enter key is pressed I am wanting the same functionality as I have when I click the button. In this case it is lauching the cfwindow and passing the parameters. Please forgive my poor usage of the jargon ;)

That almost did it. The cfwindow now pops open when the cursor is in the text field and enter is pressed but immediately after that behavior the entire page is refreshed.

That is the default action of a form with only one field, try this...

change..
onKeyPress="doSearch(event);"

to..

onKeyPress="doSearch(event);return false;"

That did the trick but now the search box is disabled. I can put the cursor in the text box but I can not type a new search term or delete the default value.
