TextField - Read failing in custom objects using getFieldValue() function.

[SanjayAgarwal]

Hi,

We are trying to read the value of text field ( In field options it is text field and not text area) using custom objects like $CM.getFieldValue() by passing correct arguments. But it fails with error that textField.get_value() is not defined function.

As a wordaround I am using $("#textFieldID").html() to get the value but is there more generic way to read it in javascript? 

[DavidPetty]

Sanjay, calling the $CM.getFieldValue([field id]) needs to be called within the Sys.Application.add_load(function() { }); function like so:

Sys.Application.add_load(function() {
     var txtFieldValue = $CM.getFieldValue(1234);
});‍‍‍

Hi David,

Yes currently it is part of add_load method but still getting the error at in debugger windows at below code snippet - 

, _getTextFieldValue: function (field, other, newValue) {
if (newValue !== undefined) {
return newValue;
}
var val = null, textField = null;
if (field.displayControl == 1) {
textField = this.getFieldControl(field);
if (textField) {
val = textField.get_value();
if (val == '') {
val = null;
}
}
}

The Bold portion above fails with error::

   Object doesn't support property or method 'get_value'

Please see the code example above.  What you have isn't how the getFieldValue() function works.

[DavidPetty]

Also make sure the field is on the layout and not in a tab that's not the default tab.

[SanjayAgarwal]

I tried with one more field which is on default layout and kept minimal code as per example above but still getting same error. Any thoughts please.

[DavidPetty]

Can you post your complete custom object code?

[SanjayAgarwal]

Update: Below code works well in Edit mode but not in view mode. Do we have different function to read value in read mode? 

<script type="text/javascript">
Sys.Application.add_load(function(){
var txtFieldValue = $CM.getFieldValue(122625);
});
</script>

[DavidPetty · Accepted solution]

Yes, that function only works in edit mode.  You'll have to use $("#textFieldID") for view mode.

You can use the following to detect which mode the record is in (inside of Sys.Applicaton.add_load):

ArcherTech.UI.GenericContent.GetInstance().get_mode();   // 1 = Edit, 2= View‍

Thanks again David! Also thanks for sharing correct way to read the mode of record. This will make coding much easier.
