Restrict specific characters/symbols from being accepted in field

Forms
1

We have a text field 'Project'.

How do we restrict users from typing in any of the following # % * : < > ? / |

Or accomplished in a different way, how do we stop people from submitting the form if those characters are using in our Projects field?

Thank you.

Hello @Viorel,

You can either add a code to replace symbols while user is typing

fd.field('FieldName').$on('change', function(value) {
    fd.field('FieldName').value = value.replace(/([\/\,\!\\\^\$\{\}\[\]\(\)\.\*\+\?\|\<\>\-\&])/g, "");
});

or add custom validation as described in this post:

Hello @mnikitina

This is really odd, neither of them work.

For the first JS I only replaced FieldName with Project and it doesn't work.

For the second option I tried two things and neither worked:

Any ideas?

Maybe the rest of my JS code is conflicting and disables this code?

Hello @Viorel,

Most probably there is an error in the code. Please check the browser console (CTRL+SHIFT+J) for the errors and share the screenshot.

You're right. Error for the first JS code:

fd.field('Project').$on('change', function(value) {
    fd.field('Project').value = value.replace(/([\/\,\!\\\^\$\{\}\[\]\(\)\.\*\+\?\|\<\>\-\&])/g, "");
});

For the second JS code:

fd.spRendered(function() {
    fd.field('Project').validators.push({
    name: 'Invalid characters',
    error: "Please remove invalid characters",
    validate: function() {
    	var str = fd.field('Project').value;
    	return !/[~"#%&*:<>?/\{|}.]/g.test(str);
    }
    });
});

Error:

Without either of the js codes, there are no errors.

@Viorel,

Make sure you are using the internal name of the field in the code.

Also, if you are suing Public Web Forms, you need to replace spRendered with rendered.

Changing spRendered to rendered solved my issue.

Final JS code where 'Project' is the field:

fd.rendered(function() {
    fd.field('Project').validators.push({
    name: 'Invalid characters',
    error: "Please remove invalid characters",
    validate: function() {
    	var str = fd.field('Project').value;
    	return !/[~"#%&*:<>?/\{|}.]/g.test(str);
    }
    });
});
