How to check if a field is blank and if so do something...

Posted on by USA80

On my entity I have a dozen or so fields. When the field called, "ExtractID" is blank, the users are suppose to fill in the data for the other fields. When Extract ID contains data, I then need all other fields to wipe out the data (so to be null).

How can I do this with java script?

Hi,

could be something along these lines:

if(Xrm.Page.getAttribute("...").getValue() != null)//Check if extractid field is not null, then wipe out all other fields

{

Xrm.Page.getAttribute("...").setValue(null);

Xrm.Page.getAttribute("...").setValue(null);

Xrm.Page.getAttribute("...").setValue(null);

Xrm.Page.getAttribute("...").setValue(null);

...

}

else{ //Otherwise, make those other fields required

Xrm.Page.getAttribute("...").setRequiredLevel("required");

Xrm.Page.getAttribute("...").setRequiredLevel("required");

Xrm.Page.getAttribute("...").setRequiredLevel("required");

Xrm.Page.getAttribute("...").setRequiredLevel("required");

...

}

Hello,

You can use following code to get value of a field:

var fieldvalue = Xrm.Page.getAttribute("schema field name here").getValue();

To set field to required level (when your ExtractID is empty) you can use following:

Xrm.Page.getAttribute("other field schema name").setRequiredLevel("required");

To empty the same field when ExtractID is not empty you can use

Xrm.Page.getAttribute("other field schema name").setRequiredLevel("none");

Xrm.Page.getAttribute("other field schema name").setValue(null);

Feel free to get in touch if you have trouble combining this lines.

I can't make those fields required as sometimes the people filling out the form wont know what the answer is for those fields yet. By default these other fields are filled in first, and then the record is usually saved. Then the ExtractID field is filled in later. When this field is filled in, I need those other fields to be null. But if those other fields have data in them and ExtractID field is blank I need the data to show in those fields. Hope that makes sense.

If you don't want them to be required, don't make them required - just remove that "else".. If you want to hide the fields at some point, use setVisible:

Try that:

function iBAMExtractIDOnChange()

{

var iBAMExtractID = Xrm.Page.getAttribute("nhs_ibamextractidlookup").getValue();

if (iBAMExtractID != null || iBAMExtractID != 'undefined' || iBAMExtractID !='')

{

Xrm.Page.getAttribute("new_claimformat").setValue(null);

Xrm.Page.getAttribute("nhs_claimsextractlayoutcomments").setValue(null);

Xrm.Page.getAttribute("nhs_fileformat").setValue(null);

Xrm.Page.getAttribute("new_invoiced").setValue(null);

Xrm.Page.getAttribute("new_frequency").setValue(null);

Xrm.Page.getAttribute("nhs_filetype").setValue(null);

Xrm.Page.getAttribute("new_trailerfile").setValue(null);

Xrm.Page.getAttribute("nhs_claimsextractftpprovider").setValue(null);

Xrm.Page.getAttribute("new_finalftpfolder").setValue(null);

Xrm.Page.getAttribute("new_filename").setValue(null);

}

}
