Problems mixing Flash & non-Flash form elements...

[rmarmer]

I have a flash cfgrid wrapped inside a non-flash cfform tag along with other
non-flash form elements. When the user selects a grid row, the flash cfgrid
onchange calls an actionscript, the actionscript calls a javascript function
passing the selecteditem grid row values which are used to populate the other
form elements via javascript & DOM.

I started off cautiously with explicit numerical & string values - not a
problem. But when I tried to pass values dynamically, only the variables
containing numerical values were recognized by the javascript. Below is the
test I ran... here are the results:

Initial Grid Row Values:

someNumber = 578;
someString = "myString";

TEST 1: myVar = someGrid.selecteditem.someNumber;

>> actionscript alert outputs: "578number".
>> javascript alert outputs : "578number".

TEST 2: myVar = someGrid.selecteditem.someString;

>> actionscript alert outputs: "myStringstring".
>> javascript alert fails.

TEST 3: myVar = "578";

>> actionscript alert outputs: "578string".
>> javascript alert outputs : "578number".

TEST 4: myVar = "578";

**changed actionscript getURL() to pass asType instead of myVar...

>> actionscript alert outputs: "578string".
>> javascript alert fails.

I'm viewing in IE, but to check the JS I switched to Firefox & the following
message showed up in the JavaScript Console when it failed on TEST 2:

Error: myString is not defined
Source File: javascript: passStr(myString)

Does anyone know if there is any way to pass dynamically created string
variables to javascript via the getURL() actionscript function?



<script language="javascript">

function passStr(msg)
{
var jsType = typeof(msg);

alert(msg + jsType);
}

</script>


<cfsaveContent variable="onClick">

var myVar = some-grid-row-value;

var asType = typeof(myVar);

alert(myVar + asType);

getURL("javascript:passStr(" + myVar + ")");

</cfsavecontent>


<cfform name="someForm">

<cfgrid name="someGrid" query="someList" onChange="#onClick#"
rowheaders="false" format="flash" >

<cfgridcolumn name="someNumber" header="Job">
<cfgridcolumn name="someString" header="Data?">

</cfgrid>

</cfform>

I am having a similar error. I have a flash cfgrid within an HTML form. The
grid is not passing or populating the needed arrays of values to the action
page. I have a case logged with MM support. I will get back to this forum when
I know more.

Thanks!

Hey,

I finally got the following to work... note: the single quotes (it's hard to
see with the font used in this forum)
around " + myVar + " but within the paren in 2 & 3 !

See if this does it for you...


javascript: alert(msg + '/' + typeof(msg));

1) myVar = 999;
getURL("javascript:callJS(" + myVar + ")");

js output: 999/number

2) myVar = "myString";
getURL("javascript:callJS('" + myVar + "')");

js output: myString/string

3) myVar = 999;
getURL("javascript:callJS('" + myVar + "')");

js output: 999/string


Just out of curiosity...

The two main reasons that I am not enclosing everything in format=flash
context are:
1) Flexibility!

2) The relative cost in user perception caused by flash forms having to
re-initialize every time the user switches back & forth btw pages...

Howvever, at the same time, & from a "lazy developer" perspective, I'd still
like to use flash form elements if I can arrive at what feels like a reasonable
compromise.

In this case, the compromise is using only the grid in flash format. This buys
me;

1) The benefits of cfgrid in flash format

2) The flexibility to still use html form elements such a s fieldset...

2) The non-flash form elements load immediately, drawing the users attention
to those elements & making the initialization of the flash grid seem to take
less time - or so the logic goes...

What is your rationale around mixing & matching?

Thanks!

My rationale is very much the same as your's for using the flash version of
cfgrid.

1. I don't want users to have to download or use the JVM from Sun or Microsoft
in order to use my application.
2. I am not a fan of applets and flash is more light weight.
3. Within my company, we have flash as a standard install on all machines, so
I know it will work on any machine. The applets are hit and miss.
4. I also like the look and feel presented by the flash cfgrid. It provides a
better display of the data and not so much scrolling is need to view it.

Thanks for the info! I will try what you provided. I have not heard anything
back on my case from Macromedia. When I do I will post it.
