There have been several requests recently for the ability to have custom validation in Nintex Forms using JavaScript and/or how to submit a form via JavaScript. Here you will find an example of how to accomplish this.

 

Here is a sample JavaScript that can be inserted into 'Custom JavaScript' in your form settings:

JavaScript
  1. //Sets fields in parameter to have a red background.
  2. function showInvalidFields(fields){ 
  3.   
  4.         for (var i = 0; i < fields.length; i++) {
  5.       
  6.         fields<i].css('background-color', 'red !important');    }
  7.   
  8. }
  9.  
  10. //Sets fields in parameter to have a white background.
  11. function resetInvalidFields(fields){ 
  12.   
  13.         for (var i = 0; i < fields.length; i++) {
  14.       
  15.         fieldsfi].css('background-color', 'white !important');    }
  16.   
  17. }
  18.  
  19. //Pass Client ID configured in Control to this function.
  20. function validateBlankField(nfclientid){
  21.   
  22. if(!NWF$('#' + nfclientid).val().match(/./)) return false;
  23.   
  24.     return true;
  25.   
  26. }
  27.  
  28. //Pass label of out of the box 'Save and Submit' button as parameter.
  29. function submitForm(buttonName){
  30.   
  31.     var validated = true;
  32.     var invalidFields = ];
  33.     var validFields = r];
  34.   
  35.     //Validating the field 'mytextbox'.
  36.     if (!validateBlankField(mytextbox)){
  37.         validated = false;
  38.         invalidFields.push(NWF$('#' + mytextbox));
  39.     }
  40.   
  41.     else{
  42.         validFields.push(NWF$('#' + mytextbox));
  43.     }
  44.  
  45.     //If form passes validation, submit.
  46.     if(validated){
  47.         resetInvalidFields(validFields);
  48.         NWF$(".nf-disableonsubmit>value="+buttonName+"]").click();
  49.     }
  50.   
  51.     //If form fails validation, show invalid fields and prompt.
  52.     else{
  53.          resetInvalidFields(validFields);
  54.          showInvalidFields(invalidFields);
  55.       
  56.         alert('The form is invalid, please correct the highlighted fields, and submit again');       
  57.     }
  58. }
 

 

Example script Usage:

 

Add a Textbox and give it a Client ID  of 'mytextbox'.

Add a button and set its action to 'Save and Submit'. Set its label to 'mysubmitbutton'.

Add another button and set its action to 'JavaScript'. Set its label to 'Submit' and its 'Client Click' setting to 'submitForm('mysubmitbutton');'.

Place the 'Submit' button over the 'mysubmitbutton' so that the 'mysubmitbutton' is hidden.

Preview the form and try to submit the form with 'mytextbox' blank. You should get an alert indicating a field should be corrected and it will be highlighted.

Note: This solution is fully compatible with the built in Validation system in Nintex Forms however, this validation will occur prior to the form being evaluated by the built in Forms Validation.

I'm using Nintex Forms 2010 and IE11.  I got the validation to work but the fields will not highlight in red.  Any ideas?

This seems to work great for single-line text fields.

However, the highlighting only works for single-line text fields.

Also, the validation fails on multi-line text fields - it won't let the submission go through.

Are there any updates to this script for these issues?

Thanks in advance!

Hi Larry,

I only ever wrote this for single-line text fields as that was what suited my needs at the time. That said, if I get some time I will look at expanding this out to support other control types.

What fields specifically are you looking at other than multi-line text fields?

Cheers!

Aaron

I'm working on a very large form, and it uses every data type: single-line text, multi-line text, choices as dropdowns, choices as checkboxes, lookups as dropdowns, dates and of course, numbers as integers, currency and percentages, although it appears that Nintex Forms treats numbers as single-line text boxes.

Thanks again for your efforts!

When I tried for Dropdown , lookup control doesn't hightlight in RED! please help the css

DropdownCtrl.css('background-color', 'red !important');  --- > doesn't work here

 

I am trying to highlight drop down menus too.  However I can only highlight single line text fields.  Does anyone have a solution to this?

// validate list lookup field

  1. if ((!validateBlankField(listLookup))||(NWF$('#' +listLookup).val()=="**SelectValue**")){
  2.         validated = false;
  3.         listLookup = listLookup.replace("_hid","");
  4.         invalidFields.push(NWF$('#' + listLookup));
  5.     }
  6.   
  7.     else{
  8.         validFields.push(NWF$('#' +listLookup));
  9.     }

Are you able to apply CSS to lookup fields dynamically?  As mentioned by @Prashanth Hamse 
DropdownCtrl.css('background-color', 'red !important'); --> doesn't work.

Try this insert this in form setting in Custom CSS

.redborder {
 border: 2px solid red !important; 
 }

and replace

fields.css('background-color', 'red !important'); 

to 

fields.addClass("redborder");  

for remove 

fields.removeClass("redborder");
