Required minimum characters in service catalog variable

[katelynlassan]

I have an item in my Service Catalog that needs to have a single line text field that will only allow a numeric value and no less than 7 digits.

i am using the following client script which prompts a pop up box warning stating a number is needed for this field, but once you acknowledge the box, the system considers the field fulfilled even though there are still letters in the field as opposed to numbers. It will still let me submit the request with letters in that field.

Also, i am using the following variable attribute to allow only 7 digits in the field, is there a way to require at least seven as opposed to no more that 7?

So, you have a couple options.   In your validation, when you display the alert you could clear the value out in the field, thus they need to enter from scratch again.   Then the required check will work correctly.   Secondly, you can have an OnSubmit script that validates it again and rejects the submission if it's not correct.

For something like this one, I would probably clear the value.

Also, for min length, when you're checking if it's a number you can also do a .length == 7 check and just update the message to reflect both requirements.

Hi Katelyn,

If I have read your comment correctly then following is your requirement:

1) The field should have only digits

2) Also the length should be exactly 7 and not less than that and not more than that

If yes then following is the approach:

1) Have a onChange script on this variable and check whether it's a digit. you can use isNaN() method of javascript and if not clear the field

2) Second you have to check whether the length is exactly 7 so you can use length property on that variable

So here is your code

function onChange(control, oldValue, newValue, isLoading) {

if (isLoading || newValue == '') {

          return;

    }

// first check whether it is a digit

var fieldValue = value;

if(!isNaN(fieldValue)){

alert("This field should have only digits");

g_form.clearValue('field_name');

}

// now check the length

if(fieldValue.length != 7){

alert("Field should have exact 7 digits");

g_form.clearValue('field_name');

}

}
