Question

ColdFusion.navigate Javascript does not work.

Asked by: pigmentarts

my problem

i have a page with a simple javascript function on it. if i run this page it works, however if i have a link to this page  like this....  href="javaScript:ColdFusion.navigate('includes/departments-new.cfm','center')" the pages loads but the  javascript function will not work.  using cfdebug it states that the function can not be found. in order to get it to work i have to add the javascript to the main index page but this means that the javascript function is on every page taking up space when i dont want it to.

question

why when i use ColdFusion.navigate to load a page in to my cflayout area why does javascript on that page stop working?


 

example this works if i run this page, however if i was to load this into one of my cflayout areas using
javaScript:ColdFusion.navigate('includes/departments-new.cfm','center') 
it stops working, "javascript function textCounter not found"
 
<!---Function to Count and Limit Characters --->
<SCRIPT>
function textCounter(field,cntfield,maxlimit) {
if (field.value.length > maxlimit) // if too long...trim it!
field.value = field.value.substring(0, maxlimit);
// otherwise, update 'characters left' counter
else
cntfield.value = maxlimit - field.value.length;
}
</script>
 
<form name="myForm" action="" method="post">
<textarea name="message1" wrap="physical" cols="28" rows="5"
onKeyDown="textCounter(document.myForm.message1,document.myForm.remLen1,125)"
onKeyUp="textCounter(document.myForm.message1,document.myForm.remLen1,125)"></textarea>
<br>
<input readonly type="text" name="remLen1" size="3" maxlength="3" value="125">
characters left
<input type="Submit" name="Submit" value="Submit">
<br>
</form>

When you use ColdFusion.navigate to populate a cfdiv or a cflayoutarea, the browser will not create the functions included in your <script> tag. You need to define all your javascript functions in the main page. This is also why you need to use cfajaximport when you use any coldfusion code that generates javascript (suchase cfform, cfwindow, etc) in a template that is intended to be used within a cflayourarea, or a cfdiv, or a cfwindow.

So just cut the Function to Count and Limit Characters code out of the 'includes/departments-new.cfm' file and place it in the head of the template with your cflayout tags.

thanks SBennett, yes taking it out and putting the function in the head of the main page does indeed work. i wanted to try and cut the amount javascript on the main page as it has all my cfajaximport as you stated, but it looks like this is not an option :(

thanks
