Concatenate in Dynamics 365 with JavaScript

Updated: Dec 17, 2018

Introduction to using JavaScript with Dynamics 365 forms and fields

  • I have created 5 fields, shown below

  • All of them are Single Line of Text fields, except for State which is a global option set

Concatenate Dynamics 365 Fields with JavaScript
  • Open up Visual Studios, you can download the free version here

  • Click "New File" in the top left, shown below

  • Click the File tab in the top left and select Save As or press Ctrl Shift S

  • Name the file something sensible like FullAddress.js, make sure to include .js or select the file type from the "Save as type:" drop down

Copy the following code into Visual Studio Code:

//Create a function and REMEMBER THIS FUNCTION'S NAME function CreateFullAddress() { //Create a variable for each of the form's fields //Name the variables sensibly and set them equal to the field's logical name //Get the logical name from the form editor var street = Xrm.Page.getAttribute("new_streetaddress").getValue(); var city = Xrm.Page.getAttribute("new_city").getValue(); //Use .getText() for the State field because it is a global option set field //Using .getValue() would return the state's option set value, example 100,000,000 var state = Xrm.Page.getAttribute("new_state").getText(); var zip = Xrm.Page.getAttribute("new_zipcode").getValue(); //Create a variable to contain the concatenated values var fullAddress = ""; //Create conditional checks for blank or null values if (street != "" && street != null) { //Add the street value to the fullAddress variable //Add a coma and space afterwards fullAddress += street + ", "; } //Repeat the conditional checks for the rest of the fields //Repeat the addition of a coma and space to each field if (city != "" && city != null) { fullAddress += city + ", "; } if (state != "" && state != null) { //Only add a space after state, no comma fullAddress += state + " "; } if (zip != null) { //Do not add anything to the end zip code fullAddress += zip; } //push the concatenated value into the fulladdress field on the form Xrm.Page.getAttribute("new_fulladdress").setValue(fullAddress); }
  • Click the File tab in the top left and select Save or press Ctrl S

  • Please examine the code, read the comments and understand the purpose of each step

  • Open up your Dynamics 365 solution or select Customize the System from Settings

  • Scroll down and select Web Resources from the entity list on the left, see below

  • Click New above the Web Resources Sub-grid to create a new Web Resource

  • Choose a sensible logical name for the web resource

  • Choose a sensible Display name for the web resource

  • Select "Script (JScript)" from the Type drop down

  • Upload the JavaScript file with the "Choose File" button

  • Click Save at the top of the window and then select Publish

  • Navigate to the form where we will use the Web Resource

Which fields act as inputs in our function?

  • Street Address, City, State, Zip Code

  • Double click the Address field to open the Field Properties Menu

  • Select the Events Tab

  • Click "Form Libraries" to expand the corresponding section


  • Click the green Add button

  • Search for the Web Resource that you just uploaded, Type in new_ and then the Web Resources Name

NOTE: I suggest using folders for your Web Resources, that is why my file path is new_/Scripts/Project/FullAddress.js

  • Select the Web Resource and click add

  • Navigate to the section below Form Libraries labeled Event Handlers

  • Notice that the event selected from the Event drop down is OnChange

  • We are telling the system that we want an event to occur if the field value changes

  • In our case we want to execute a JavaScript function

  • Click the green Add button to add an Event Handler

  • Select the Web Resource from the Library drop down

  • Type in the function from the JavaScript file that we would like to execute if there is a field value change to Street Address, example "CreateFullAddress"

  • Make sure Enabled is checked, and select OK

  • Do the same exact steps for the other input fields, City, State, and Zip Code

  • Click Save and then click publish

  • Navigate to the form and make a change to any of the input fields to test your function

  • You're all set!
