Conditional Statement on a lookup field in JS

Posted on by HK

Hello,

I am using js to display or hide buttons on a form.

One snippet of the query is:

if (attributes[i].getIsDirty()
&& attributes[i].getName() != "decision" && attributes[i].getName() != "decisiondate" ) {<do stuff>}

The condition is working correctly on the normal date field, however is not working on the 'decision' field which is a lookup field.

Do I need different syntax to get this to evaluate a lookup field correctly?

Thanks in advance.

Hi Alex Br,

Add alerts or debug the code in both conditions where it is working and where it is not working. The issue might be resolved by you.

If I answer your question then please mark it as verified.

Let me know if I can provide you with more details.

Thanks

For lookups you have to get the name like below

attributes.get("fieldname").getValue()[0].name

Hi Alex Br,

Can you give more context about the attributes array?

And you should be able to debug by adding some console logs to see the return value of "getName()", sometime the name would be different, it is determined by how/where you get the attributes array.

if (typeof CRM === 'undefined') CRM = {};

if (typeof CRM.EntityName === "undefined") CRM.EntityName = {};

CRM.EntityName.Onload = function (executionContext) {
var formContext = executionContext.getFormContext();

formContext.getAttribute("decision").addOnChange(function () { CRM.EntityName.Function(formContext); });
formContext.getAttribute("decisiondate").addOnChange(function () { CRM.EntityName.Function(formContext); });

}
};

CRM.EntityName.Function = function (formContext) {

//Do Stuff
};

Above is an example of how to trigger logic based on onchange of specific fields. You can use this as reference

First take value in a variable

var abc=attributes.get("fieldname").getValue()[0].name

Then Apply condition

if (abc!=null && abc!=""){

//Code for showing Button

}else {

//Code For Hide Button

}
