Managed Metadata

[stieland]

I am trying to work with Managed Metadata fields and have not been able to pick up the change event for a Managed Metadata field.

fd.field('RCategory').change(function() {
alert('Category Changed');
});

Never fires the alert. Do Managed Metadata fields work differently?

[Dmitry Kozlov]

Please, try to use the following code to handle changing of Management Metadata field:

Code: Select all

var container = fd.field('InternalName').control()._el().find('.ms-taxonomy').get(0);
container.JavascriptOnValidation = "alert('Managed metadata changed!')"; 

[stieland]

While that is firing when the item is updated, also a few more times. I am still missing a few items to get my piece working.

I need to know when the managed metadata field equals 'Option 2' and if it equals 'Option 2', then I need to make another control visible. If it does not equal 'Options 2' then the other control is hidden.

I do not seem to be able to get the value of the managed metadata field so that I can compare it.

You can find examples of getting and setting Taxonomy field values in the following article:

http://blog.vgrem.com/tag/taxonomywebtaggingcontrol/

Getting:

Code: Select all

var container = fd.field('InternalName').control()._el().find('.ms-taxonomy').get(0);
var taxCtlObj = new Microsoft.SharePoint.Taxonomy.ControlObject(container);
var termValue = taxCtlObj.getRawText();

Should that alternat event registration also work for SP 2010?

I did put that code into the JavaScript part of the form, but the alert never shows up...

[Dmitry Kozlov]

Please, try the following code for SP2010:

Code: Select all

var container = fd.field('TermStore1').control()._el().find('div.ms-taxonomy').get(0);
container.JavascriptOnValidation = "alert('Managed metadata changed!')";

It seems like the only thing you can do in here is report out that it's fired. Trying to call an handler function doesn't seem to work properly. I've tried a couple things and some variations of them:


container.JavascriptOnValidation = "mmChangeHandler()";


function mmChangeHandler() {

console.log("Managed Metadata Changed!");

}

/* OR */

container.JavascriptOnValidation = function() {

console.log("Managed Metadata Changed!");

}

You can define a global function and then call it:

container.JavascriptOnValidation = "func()";

Code: Select all

window.func = function () { 
   console.log("Managed Metadata Changed!");
}

That worked! Thanks!

Hi!

I checked with alert and it works fine indeed. I need to insert the check for mandatory field with metadata. I tried some options like:

fd.field('FieldName').control()._el().find('.ms-taxonomy').value()

fd.field('FieldName').control()._el().find('.ms-taxonomy').value() == ""

fd.field('FieldName').control()._el().find('.ms-taxonomy').length > 0

but nothing works Howcan I use it in IF statement to check if the metadata field contains any information?
