set title if headline changes

begood321

Hey Guys,

How do I change this code to set title item to equal the headline item from 1st input no matter how many times headline item changes on a form.

function setHeadline()
{
var headlineItem = IWDatacapture.getItem("/Headline");
var headline = headlineItem.getValue();

if (headline != null)
{
var metadataItem = IWDatacapture.getItem("/Metadata/title");
metadataItem.setValue(headline);
IWDatacapture.redraw();
}
}

Thanks

I'm not sure I understand the question - are you saying that if title is empty and Headline is set to "foo" - you want title set to "foo" - and that if they then change Headline to "bar" - you want to keep title set to "foo" (your code seems to do this already) - but if someone manually goes in and clears out "title" and changes Headline to "baz" you want title re-set to "foo"? - If so, when you set title - you should make it readonly - and you should also check to see if it has a value during init() and make it readonly then too.

If that's not what you were asking - then please try to add more detail to your question.

Fish thats exactly what I want, but can you help me out with the code. I have tried changing around the code to get it working but I got it to this point.

Please READ the FormAPI Developer's Guide and then look at your code again - it is simple to adjust your existing code to make the title field readonly after setting it, and it is equally simple to test the title field and make it readonly on form initialization.

If you have a bunch of money to burn and you want to throw some my way to have me come in and code the above for you - fine - but the above is pretty trivial code and shouldn't require that kind of external assistance (IMHO)

Tried setReadOnly(True) as per formAPI but title still changes, can you tell me what am I missing or not doing.

It should be true not True.

If it still doesn't work - please post the latest code - with as much context as warranted.

Still didn't work. Here is the code from javascript file linking to datacapture.cfg file. This is 1st version. Tried other things like while and for loops, break command out of loop still didn't work. So It put it back to original version here. I know its simple but its really kicking my but.

function init()
{
// update metadata.title
IWEventRegistry.addItemHandler("/Headline", "onItemChange", setHeadline);
}

function setHeadline()
{
var headlineItem = IWDatacapture.getItem("/Headline");
var headline = headlineItem.getValue();

if (headline != null)
{
var metadataItem = IWDatacapture.getItem("/Metadata/title").setReadOnly();
metadataItem.setValue(headline);
IWDatacapture.redraw();
}

}

Try "/Root/Headline" and "/Root/Metadata/title"

This is assuming you have xml style DCRs.

Also, you do not shot it, but how are you running init ? I assume you have an onFormInit event captured somewhere.

Like this in the before function init()

IWEventRegistry.addFormHandler("onFormInit", init);

Tried it, still doesn't work. Thanks

Can you post your entire JS and DCT ? Did you read my updated changes about he onFormInit ?

function init()
{
// update metadata.title
IWEventRegistry.addItemHandler("/Headline", "onItemChange", setHeadline);

function setHeadline()
{
var headlineItem = IWDatacapture.getItem("/Headline");
var headline = headlineItem.getValue();

if (headline != null)
{
var metadataItem = IWDatacapture.getItem("/Metadata/title").setReadOnly();
metadataItem.setValue(headline);
IWDatacapture.redraw();
}

}

Event handler pass a parameter, your function is not defined as such, setReadOnly requires a parameter and should only be set after you've populated the field - try altering it as follows:

function setHeadline(item) {
    var headline     = item.getValue();
alert("headline: " + headline); // debugging - make sure we get something

    if (headline != null) {
        var metadataItem = IWDatacapture.getItem("/Metadata/title");
        if(metadataItem.getValue() == null){
            alert("Setting title value"); [color=red]// debugging
            metadataItem.setValue(headline);
metadataItem.setReadOnly(true);
        }
        else {
            alert("title already has value: " + metadataItem.getValue()); // debugging 
        }[/color]
    }
}

In addition - you want to augment the init function like this:

function init() {
    // update metadata.title
    IWEventRegistry.addItemHandler("/Headline", "onItemChange", setHeadline);
// make title readonly if already populated
var title = IWDatacapture.getItem("/Metadata/title");
    if (title.getValue() != null){
        title.setReadOnly(true);
    }
}

I believe those changes should do what you're looking for.

Ok I read your post here is

entire js file

Don't just run init; use this instead:

IWEventRegistry.addFormHandler("onFormInit", init);

Ok I run your script but it doesn't put any value in title field. It should put and keep 1st headline value in title field even if headline field changes, title field will always retain 1st input of headline value. Will still work with it to see if I get desired result. Thanks

huh ?

Post what change you made since there have been multiple suggested.

Try the alerts (if you have not already) suggested in Adams post from 9:24 and tell what happens

Thanks Guys for all your help, I got it working. Now I can have good weekend. Here is my solution.

var h=0;
function init()
{
// update metadata.title
IWEventRegistry.addItemHandler("/Headline", "onItemChange", setHeadline);
// make title readonly if already populated
var title = IWDatacapture.getItem("/Metadata/title");
if (title.getValue() != null){
title.setReadOnly(true);
}
}

function setHeadline(item) {
var headline = item.getValue();
//alert("headline: " + headline); //make sure we get something

if (headline != null) {
var metadataItem = IWDatacapture.getItem("/Metadata/title");

if(metadataItem.getValue() != null && h==0) {
//alert("Setting title value");
metadataItem.setValue(headline);
metadataItem.setReadOnly(true);
h=h+1;

}
else {
//alert(title already has value: " + metadataItem.getValue());
}
}
}

I'm glad it's working for you now - though I'm not sure you really need that 'h' variable - but if you're happy, we're happy ;-)

begood321

h variable was needed. Before title changes everytime headline changes, but when h is declared everytime function is called h is incremented by 1 so title always remains same from if statement because h==0 always from 1st input of headline. Thanks ;-)

That's because you're testing to make sure that title is not null before setting it - whereas you should be testing that it is null (see my previously posted code)
